  Revision of the Afrotropical Xantholinini (Coleoptera Staphylinidae)

  ABSTRACT
  A revision of the staphylinids Xantholinini (Coleoptera) of the Afrotropical Region is presented including a historical review, a discussion of diagnostic characters, morphology and techniques and some conclusive remarks mostly on the zoogeography of this group in Africa south Sahara. Twenty-nine genera and 425 species are recognized, 14 genera and 273 species are described as new. Linosomus Kraatz, 1857 sensu nov. and Notolinopsis Casey, 1906 sensu nov. are redescribed. Pedinolinus Bernhauer, 1912 is placed in synonymy with Nudobius Thomson, 1860; Elgonia Bordoni, 2001 and Echdisia Bordoni, 2007 (n. g. for Elgonia, n. preoc.) with Notolinopsis Casey, 1906 sensu nov., and Notolinus Casey, 1907 with Linosomus Kraatz, 1857 sensu nov. On the specific level, Leptacinus cephalotes Coiffait, 1968 is placed in synonymy with Microafra minutissima (Cameron, 1959); Xantholinus microphthalmus Bernhauer, 1939 with Nudobius micropterus (Bernhauer, 1939); Nudobius magnus Cameron, 1956 with N. nigrocyaneus Chapman, 1939; N. pulcher Tottenham, 1956 with N. burgeoni Bernhauer, 1934; N. opacinus Tottenham, 1956 with N. abessinus Bernhauer, 1915; N. concinnus Tottenham, 1956, N. meruensis Cameron, 1951, N. cinctipennis Scheerpeltz, 1956 with N. quadriceps Cameron, 1929; Pedinolinus subviridipennis Bernhauer, 1912 with Nudobius pictipennis (Fauvel, 1904); Gauropterus methneri Bernhauer, 1908 with G. nasutus (Harold, 1879); G. adjacens Tottenham, 1939 with G. hauseri Bernhauer, 1937; Xantholinus abessinus Bernhauer, 1931, X. aeneipennis Bernhauer, 1934, X. tripunctatus Tottenham, 1951 with Gyrohypnus remotus (Eppelsheim, 1895); Mitomorphus dubitans Tottenham, 1956, M. evanescens Tottenham, 1956, M. angolensis Cameron, 1959, M. gabonicus Coiffait, 1968 with Belinga africana (Bernhauer, 1929); Pachycorynus conradsi Bernhauer, 1937 with Aleutia marginella (Fauvel, 1905); Xantholinus capensis Boheman, 1858 with Notolinopsis fallax Sachse, 1852; Notolinopsis diligens Casey, 1906 with N. capensis Casey, 1906; Xantholinus bicoloripennis Scheerpeltz, 1974 with Linosomus tenuicornis (Nordman, 1837); Notolinus parvus Casey, 1906, Notolinopsis incultus Casey, 1906, Leptacinus caffer Scheerpeltz, 1074, L. natalensis Scheerpeltz, 1974, L. brincki Scheerpeltz, 1974 with Linosomus socius (Fauvel, 1877); Leptacinus aethiopicus Bernhauer, 1931 with Balchis abessina (Bernhauer, 1931); Leptacinus macropterus Bernhauer, 1939 with Agaporina elgonensis Bernhauer, 1939; Leptacinus luofuensis Cameron, 1950 with Byziniella abacta (Tottenham, 1956); Leptacinus pholeobius Jeannel et Paulian, 1945 with Byziniella hypsibatha (Bernhauer, 1939); Leptacinus parvus Cameron, 1950 with Byziniella debilis (Cameron, 1950); Leptacinus irritans Tottenham, 1956, L. pallescens Tottenham, 1956 with Byziniella shoutedeni (Cameron, 1929); Xantholinus longipennis Cameron, 1950 with Byziniella wittei (Cameron, 1950); Leptacinus vicinus Coiffait, 1968 with Leptacinus oculatus (Coiffait, 1968).
