Congo), P. aethiopicus n. sp. (Etiopia), P. baehri n. sp. (Namibia), P. balyi n. sp. (Angola), P. beharui n. sp. (Etiopia), P. bertiae n. sp. (Madagascar), P. bezdeki n. sp. (Rep. Pop. Congo), P. bracarumvestitus n. sp. (Rep. Pop. Congo), P. bryanti n. sp. (Mali), P. burgeoni n. sp. (Natal), P. camerun­ensis n. sp. (Camerun), P. cristiani n. sp. (Namibia), P. crocodilinus n. sp. (Zambia), P. daccordii n. sp. (Yemen), P. danielssoni n. sp. (Sierra Leone), P. danielssoni congoanus n. ssp. (Rep. Pop. Congo), P. demeyeri n. sp. (Rep. Pop. Congo), P. episternalis n. sp.

The lectoypes of P. conspersus Gerstaecker, 1871, P. senegalensis Achard, 1914, P. latior Pic, 1921 and P. testaceipes Fairmaire, 1880 are designated. A new synonymy (P. costatus Achard, 1914 n. syn. of P. torridus Baly, 1878) and a nomenclatural change (Mecistes lineatus (Pic, 1921) n. comb. for Pachnephorus lineatus Pic, 1921) are proposed; the Lectotypes of M. lineatus and of M. flavipes (Gerstaecker, 1855) are designated.
