RICCHIARDI, PERISSINOTTO, and CLENNELL: Breviclypeus, a new South African Trichiina genus (Coleoptera: Scarabaeidae, Cetoniinae)

Breviclypeus, a new South African Trichiina genus (Coleoptera: Scarabaeidae, Cetoniinae)


A new genus, Breviclypeus gen. nov., endemic to South Africa, is erected. The type species is here designated to be Agenius rufipennis Gory & Percheron 1833 (comb. nov.). A second species, Campulipus plagosus (Pèringuey, 1885) is recognized to belong into this new genus (comb. nov.). Consequently, the genus Campulipus Kirby, 1827 is now represented by three species only, Campulipus limbatus (Olivier, 1789), Campulipus clavus (Schaum, 1844) and Campulipus suturalis (Waterhouse, 1885). A fourth taxon, Agenius nobilis J. Thomson, 1878 is here transferred to Campulipus (comb. nov.) and synonymized with C. limbatus (syn. nov.) The two genera not only exhibit key morphological differences, but also occupy different habitats and diverge substantially in their ecology. An updated key of the genera of South African Trichiina is also provided. A separate key is provided for the genus Breviclypeus.


This work, like previous others (Ricchiardi 1997, 1998, 1999, 2000, 2015; Ricchiardi et al. 2004, 2008, 2013, 2014; Sipek et al. 2012) is aimed at enhancing knowledge of the rich Trichiina entomofauna of South Africa. Including those analysed in this study, the total number of South African Trichiina species currently stands at 39, with the description of a 40th currently in progress (Ricchiardi, in press). These are subdivided into 12 genera, three of which are not endemic to the country, namely Calometopus Blanchard, 1850, Diploa Kolbe, 1893 and Myodermum Burmeister & Schaum, 1840 (Ricchiardi 1997).

A recent review of large numbers of specimens reposited in several museums and private collections has led to the conclusion that the erection of a new genus is actually necessary, in order to account for the broad morphological differences observed among the six member species that currently constitute the genus Campulipus Kirby, 1827. Some of these differences were already pointed out by Péringuey (1907), who had included them in his dichotomous key (Péringuey 1907, pag. 301), without though recognising the need for the species attributed at that stage to the genus Agenius Serville, 1828 (synonymized with Campulipus Kirby, 1827 by Krikken in 1984) to be grouped into two different genera. Upon implementing the separation into separate genera, the species that truly belong to Campulipus are: C. clavus (Schaum, 1844), C. limbatus (Olivier, 1789), C. nobilis (Thomson, 1878; new combination) and C. suturalis (Waterhouse, 1885). Campulipus nobilis was placed within the genus Agenius by Schenkling (1922), but its holotype specimen, reposited in the MNHN, is here recognised as a female of C. limbatus (new junior synonym). The remaining species, C. plagosus Péringuey, 1885 and C. rufipennis (Gory & Percheron, 1833) are now placed in a new genus, Breviclypeus Ricchiardi (gen. nov., comb. nov.), on the basis of at least two major synapomorphic characters.

E. Ricchiardi wrote the taxonomical part of this study, including the descriptions of the new genus. Renzo Perissinotto and Lynette Clennell contributed all biological and ecological observations.

Material and methods

Specimens length was measured between the apex of the pygidium and the anterior margin of the pronotum. The specimen width is the maximum elytron width. The clypeus length was measured laterally, between the frontal margin and the antennal basal attachment.

Photographs were taken using a Nikon DigitalSight DS-Fi2 camera attached to a Nikon SMZ25 dissecting microscope, or alternatively with a Nikon Coolpix P7700 attached to one of the eyepieces of a Wild dissecting microscope. All photos were processed with photo stacking software (Zerene Stacker Version 1.04 Build T20510021255, http://www.zerenesystems.com [accessed 9 Dec. 2015]) and backgrounds were removed using GIMP 2.8.16, in order to increase contrast. Individual photograms were finally merged to generate composite images using the same GIMP software.

The maps reported in Fig 3 were obtained using Google Earth Pro

The only revision undertaken so far for the genus Agenius Le Peletier & Serville, 1828 (including Campulipus Kirby, 1827, as motivated here below) was published by Péringuey (1907) at the beginning of the previous century. According to this author, Agenius included five species, but the number was later increased to six by Schenkling (1922), who added Agenius nobilis J. Thomson, 1878, previously unnoticed by Péringuey (1907).

In his literature review, Krikken (1984, p. 40), realised that the correct year of publication of the genus Agenius by Le Peletier & Serville was 1828, while Kirby had already erected the genus Campulipus in 1827, using the same type species, namely Melolontha limbata Olivier, 1789. The latter name was thus regarded as senior to Agenius. In the same review, Krikken (1984) indicated that the genus Campulipus included nine species, without though naming them. A list of nine species, probably representing the same set intended by Krikken (1984), was eventually published by Krajcik (1999) and included the six highlighted earlier by Schenkling (1922) with the addition of another three, erroneously associated with Campulipus. These, however, belongs to the Afrotropical genus Clastocnemis Burmeister & Schaum, 1840 and are actually unrelated to Campulipus. They are: Clastocnemis nigritulus (Burgeon, 1934); Clastocnemis simulator (Burgeon, 1934) and Clastocnemis tabaccoi (Burgeon, 1935).

The recent study of numerous material, both old and new, including most type specimens has revealed that two species known as Campulipus rufipennis (Gory & Percheron, 1833) and Campulipus plagosus (Péringuey, 1885) exhibit several key morphological characters (e.g. shape of male mesotibiae, clypeal structure of both sexes, etc.) that require the erection of a new genus, Breviclypeus Ricchiardi gen. nov. While Breviclypeus plagosus (Péringuey, 1885) comb. nov. is a species widely distributed throughout the eastern and central parts of South Africa, the second species belonging to this genus, Breviclypeus rufipennis (Gory & Percheron, 1833) comb. nov., appears to be restricted to the southern part of the Western Cape and is currently known from a few records only. Indeed, Péringuey (1907) had already noted its rarity and remarked as follows: “I have seen two males only of this seemingly rare species”. Since then, most of the new specimens have been collected by two of the authors of this work (RP & LC).

Description (Figs 2, 3)

Head. ♂ black, glabrous, slightly shining, shagreened; ♀ black, glabrous, matt, markedly sculptured but sometimes effaced on clypeus (one ♀ exhibits anterior clypeal margin smooth and external protibial teeth worn – most likely as a result of burrowing into soil). Antennal clubs slightly arched in ♂ and less than 1.5 times the clypeus in length; antennal club of ♀ shorter and virtually straight. Internal antennal club of both sexes with recumbent, thick, short, testaceous setae on external surface. Antennal scapus and clubs black; other segments testaceous. Clypeus broader than long in both sexes, and: ♂, anterior margin centrally straight, anterior corners strongly rounded, lateral margins rounded, posteriorly narrowing, all margins elevated and rounded; ♀ maximum width at middle of total length; anterior margin tapering.

Pronotum. Hexagonal, centrally prominent at sides, front corner produced and widely rounded, hind corner pointed or rounded, laterally not crenulated, lateral foveas absent, emarginate along full perimeter except at centre of posterior margin; without any cretaceous markings or maculae; ♂ black, glabrous, shiny, covered with scattered, rounded, small punctures; ♀ glabrous on disc; with very scattered, long, laterally erected, black setae on lateral margins. Scutellum. Black, as broad as long, arched at sides, apex rounded, covered with large, scattered punctures; or covered with small, scattered punctures.

Elytron. ♂: shiny orange, with a black juxta-sutural band not reaching scutellum, enlarged at middle to form a semioval (oval with both elytra combined) black macula; or orange, with a black juxta-sutural band not reaching scutellum, sometimes enlarged at centre; ♀: same colour as male (B. rufipennis) or black (B. plagosus). Elytron of ♂ occasionally exhibiting small cretaceous macula at centre of disc. Striae in ♂ with row of large, nearly regularly spaced punctures; or with row of small, slightly darker, nearly regularly spaced punctures. Striae in ♀ effaced or with rows of deep, large, regularly spaced punctures. Interstriae in both sexes mainly glabrous, unpunctured, flat, or first 5 and external margin of juxta-sutural interstria raised with horizontal and shiny rows. Juxta-sutural margin elevated in both sexes.

Pygidium. Black, wrinkled, nearly matt, without any cretaceous maculae; ♂ triangular, broader than long, dorsal margin semi-circular; ♀ triangular, longer than wide, dorsal and ventral margins rounded, laterally depressed in ventral half.

Abdomen. Black, without any cretaceous markings; ♂ slightly medially depressed, not hollowed longitudinally, anal sternites rounded; ♀ anal sternites shagreened.

Protibia. Black, externally tridentate; first two teeth closer to each other than third; ♀ with protibia larger than in male; ♂ first protarsal segment not laterally dilated, much shorter than second; protibial spur normally developed.

Mesotibia. Black. ♂ nearly straight, strongly enlarged apically, with a marked central tooth. Internal apical spur half as long as external.

Metatibia. Black, first metatarsal segment longer than second; ♂ nearly straight, with strong central tooth, strongly enlarged apically with long, sharp tip at dorsal apical corner; ♀ enlarging towards apex, with central very noticeable tooth, with dorsal apical corner sharply spiny.

Diagnosis. While both genera, Breviclypeus and Campulipus, exhibit a superficially similar habitus (e.g. elytral ornamentation), they can be separated on the basis of numerous diagnostic characters. In general, Campulipus species are also larger in size (12–18 mm) than their Breviclypeus counterparts (9–12 mm).

The head of Campulipus male is black, with surface covered in small, round punctures and long testaceous setae, generally bent backwards. The head of Breviclypeus is also black, shagreened and glabrous. The clypeus of Campulipus is as wide (as measured at its maximum width, at mid length of the clypeus) as long, emarginate and raised along the margins. In Breviclypeus, however, the clypeus is wider than long, raised and rounded along the entire perimeter, but narrowing posteriorly.

In female Campulipus, the clypeus is slightly less wide than long (at maximum width), with the anterior margin narrowing significantly. In female Breviclypeus the clypeus is notably wider than long (at maximum width), but again with a narrowing anterior margin. Some female B. plagosus specimens exhibit a clypeal shape worn-out due to burrowing activity. In Campulipus, the pronotum is emarginate along the entire perimeter in both sexes, and the lateral foveas are always present. In Breviclypeus, on the other hand, the lateral foveas are completely lacking and the emargination along the perimeter is interrupted at the centre of the posterior margin. In Campulipus, the male pronotum is black (occasionally with two lateral reddish bands not reaching the margins), covered in dense round punctures, effaced at sides and bearing long testaceous setae folded backwards. While the male pronotum of Breviclypeus is also black, shining, glabrous and covered in small and scattered punctures. The pronotum of Campulipus female is black and glabrous, apart from its lateral margins where numerous horizontal black setae protrude. In female Breviclypeus, the pronotum is also black and glabrous, but it exhibits only a few lateral setae. The scutellum of Campulipus is covered in frosted black coating, while that of Breviclypeus is not. In male Campulipus, the background colour of the elytra is generally reddish-orange, with black ornamentation varying from species to species. The females of Campulipus exhibit ornamentation similar to that of their male counterparts (e.g. C. limbatus), or at least have some reddish areas on the elytral surface, but can also be completely black and matt. Conversely, the elytral colour in male Breviclypeus is dark yellow to reddish-orange, with consistent black ornamentation. In Breviclypeus females, the elytral ornamentation can be similar to that of males (B. rufipennis) or completely black (B. plagosus). In both sexes of Campulipus, the protibiae are externally tridentate, with all teeth equally spaced. In Breviclypeus, protibiae are also tridentate, but the third tooth is further apart than the other two. The mesotibiae in male Campulipus are black and strongly bent, while in male Breviclypeus these are black but only slightly arched. Finally, the male metatibiae of Campulipus are black, markedly expanded at the apex and bearing a very visible tooth at the centre of the dorsal margin. The metatibiae of male Breviclypeus are similar, but exhibit an additional long and sharp tooth at the dorsal corner of the apex. Similarly, the metatibiae of female Breviclypeus bear a tooth at the dorso-apical corner, but this is less pronounced than in the male.

Derivatio nominis. The genus name is derived from its characteristically short clypeus, substantially reduced in comparison to that of species belonging to Campulipus.

Remarks. No female of either species has been previously described, thus this is the first account of this sex for the genus. Concerning biology/ecology, members of the genus Breviclypeus emerge from the soil immediately after substantial rainfall events during spring and summer. Adults have never been observed on either flowers, fruits or sapping trees and, therefore, are most likely non-feeding stages. This is reflected in their period of activity, which is normally restricted to a few days after rain. Males are far more active than females and take off around mid-morning (10:00-11:00), as soon as the temperature has reached a critical threshold of > 23 oC, after climbing up grass stems, blades and/or bush branches to reach a high point within their grassland habitat. They then fly at high speed, but relatively low above the grass searching for female pheromonal signals. Females are generally found crawling on the ground within the grassland and move slowly from one egg-laying point to the next. They are nevertheless fully winged and capable of undertaking substantial flights, particularly towards the end of their life span.

Conversely, within the genus Campulipus, both males and females are regularly found feeding on a variety of flowers either in typical succulent Karoo or fynbos plant species (e.g. Ruschia spp., Delosperma spp., Lampranthus spp.; Mesembryanthemaceae). Thus, most of the day in these species is actually spent renewing their energy reserves, while also mating on the same feeding plants. As a result, individuals remain alive and active for relatively long periods, possibly about 2-4 weeks or longer.

Intersexual differences. Size: ♀ generally slightly larger than ♂.

Colour. ♂: glabrous, black, with antennae flavescent, and elytra pale yellow to reddish, but marginated with black and having a broad sutural band reaching the suture from the apex to the median part, where it expands into a quadrate patch. ♀: glabrous, black, occasionally with humeral umbones faintly reddish-brown.

Head. ♂: clypeus short, concave, slightly arcuate in front, margins reflexed and not thick; head and clypeus glabrous and covered with deep, nearly contiguous punctures. ♀: clypeus virtually flat, slightly elevated at centre; margins not reflexed.

Pronotum. ♂: Black, slightly shiny; covered in large and deep punctures, occasionally scattered ; sub-angular laterally shortly before the median part and evenly attenuate thence to the apex or the base, which is bi-sinuate with angles acute; all margins exhibiting continuous groove parallel to edge, except on central part of posterior margin. ♀: black, matt or slightly shiny, with same shape and margins as in male; punctures are however denser, deeper and larger.

Elytra. ♂: slightly widened laterally in the median part, narrower at apex than at base: striae and interstriae marked with lines of round punctures, shallow and not incised. ♀: striae incised and marked with dense, horse-shoe punctures, deeper than in male. Interstriae slightly arched and centrally marked with lines of punctures similar to those of male, occasionally interrupted by roughness.

Mesotibia and metatibia. Tibial apex substantially more expanded in female than in male.

Venter. Substantially more convex in female.

Anal sternites. Longer in female than in male.

Distribution. Breviclypeus plagosus is a species with wide distribution range within South Africa, from Mpumalanga and KwaZulu-Natal in the east to the eastern part of the Western Cape (Fig. 1).

Remarks. In his original description, Péringuey (1885) did not specify the number of specimens examined in his work. For this reason, the type specimen reposited at the ISAM (TYPE 3392) is here designated as Lectotype. Judging from available records, the flight period of B. plagosus appears to be relatively long, with collecting dates ranging from 22 October to 6 January. On two occasions, two of the authors (RP and LC) have collected females at the end of the summer, on 14 and 15 March, respectively. The first was retrieved from Hofmeyr, but it was already dead and resting inside the crown of a plant of Aloe broomii, where it has been observed that carcasses are preserved in good conditions for long periods. The second was found in the Bosberg Nature Reserve but unfortunately there is no information available on its state (dead or alive) at the time of collection.

Remarks. Unfortunately, the holotype designated by Gory for this species has yet to be traced. However, both drawings and description contained in the work of Gory & Percheron (1833, Plate II, Figure 5) match well the specimens included in this study.

B. rufipennis is a species very poorly collected. Indeed, the majority of specimens currently available have been collected by two of the authors (RP and LC). Already in 1907, Péringuey had defined this species as “rare”. As our knowledge currently stands, the species is only known from three localities, two on the southernmost coastal area of the Western Cape (Cape Agulhas and Pearly Beach) and the third in a mountainous area above the town of Wellington, at an altitude of about 850–1000 m (Limietberge). The female was previously unknown and the recent collection of one specimen in the Agulhas National Park has finally allowed its description and the identification of differences from its male counterpart, as follows. Unlike the pattern observed in the only other species of this genus, B. plagosus, where the female elytra are completely black, the elytra of B. rufipennis female exhibit an ornamentation similar to that of its male. Among the five males currently known for this species, two have a small cretaceous spot at the centre of each elytral disc and the shape of the anterior part of the black area towards the sutural margin of the elytra is noticeably more expanded than in those males that do not exhibit the cretaceous spots (Fig. 3B).

Intersexual differences

Size. The only known female is significantly longer than the males (12 mm versus 9.5–10 mm).

Colour. ♂: glabrous, black, with antennas flavescent, elytra pale yellow to reddish, not marginated with black but with black sutural band reaching the suture from apex to median part, where it expands to assume elliptical shape. ♀: glabrous, colours of elytra as in ♂.

Head. ♂: clypeus short, concave, slightly arcuate in front, margins reflexed and moderately thickened; head and clypeus glabrous and covered with deep, nearly contiguous punctures. ♀: clypeus virtually flat, slightly raised at middle; margins not reflexed; head and clypeus both with rough but shiny surface.

Pronotum. ♂: black, glabrous and shiny; covered in small, shallow and scattered punctures; sub-angular laterally just anteriad of median part and evenly attenuate thence to the apex or the base, which is bi-sinuate with angles acute; groove running parallel to the edge on all margins, except at centre of posterior. ♀: black, glabrous and shiny, with shape and margins similar to those of male; punctures as in male.

Elytra. ♂: Slightly expanded laterally in the median part and narrower at apex than at base; striae not incised and interstriae marked with lines of round, shallow punctures. ♀: as in male.

Mesotibia and metatibia. Apex of female tibiae slightly more expanded than in male.

Venter. Substantially more convex in female than in male.

Anal sternites. Longer in female than in male.
