The African theraphosid genera Pterinochilus Pocock, 1897 and Eucratoscelus Pocock, 1898 are revised, keyed, and their species distributions mapped. The subfamily Harpactirinae is redefined and its genera keyed. The follow- ing new synonyms and transfers are proposed: Brachionopus Pocock, 1897 is transferred to the Barychelidae; Pterino- chilus chordatus (Gerstäcker, 1873) is removed from the synonymy of P. constrictus (Gerstäcker, 1873); Pterinochilus widenmanni Strand, 1906, P. raptor Strand, 1906, P. affinis Tullgren, 1910, P. sjostedti Tullgren, 1910, P. carnivorus Strand, 1917, P. brunellii Caporiacco, 1940 and Coelo- genium raveni Smith, 1990=P. chordatus; Idiothele pluri- dentata Hewitt, 1919 and Eucratoscelus tenuitibialis Schmidt & Gelling, 2000=P. lugardi Pocock, 1900; P. elevatus (Karsch, 1878) is removed from the synonymy of P. con- strictus; P. elevatus nomen oblitum, P. mamillatus Strand, 1906 and P. hindei Hirst, 1907=P. murinus Pocock, 1897 nomen protectum; P. mutus Strand, 1920=P. simoni Berland, 1917; P. constrictus is transferred to Eucratoscelus, n. comb.; E. longiceps Pocock, 1898 and P. spinifer Pocock, 1898=E. constrictus (Gerstäcker, 1873); Augacephalus, gen. n. is established for P. breyeri Hewitt, 1919 and P. junodi Simon, 1904; Idiothele Hewitt, 1919 is removed from the synonymy of Pterinochilus; P. crassispinus Purcell, 1902= I. nigrofulva (Pocock, 1898); Trichognatha, gen. n. is estab- lished for P. schonlandi Pocock, 1900. The males of Augacephalus breyeri (Hewitt, 1919), A. junodi (Simon, 1904) and Eucratoscelus pachypus Schmidt & von Wirth, 1990 are described for the first time, as is the female of Trichognatha schonlandi.
