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
