DATA ON AFROTROPICAL HISTERIDAE (COLEOPTERA), WITH DESCRIPTION OF HISTER SINDARAE N. SP. Yélamos, T., 1992. Data on Afrotropical Histendae (Coleoptera), with description of Hister sin- darae n. sp. Misc. Zool., 16: 37-43. Data on Afrotropical Histeridae (Coleoptera), with description of Hister sindarae n. sp.- Thirty nine species from the Afrotropical region are recorded, including Hister sindarae n. sp. from Gabon. This species is related to Hister montanus Marseul, 1857, but it differs from it mainly by the morphology of the outer lateral stria of the pronotum, dorsal elytral striae, subhumeral fovea, pygidium and protibiae. Two species recently descnbed from Gabon Cyclobacanius morenoi Yélamos & Gomy, 1990 and Cyclobacanius teresae Yélamos & Gomy, 1990) are also recorded. The most interesting species in relation to the localities where they were found are Saprinus cruciatus jlavipennis Péringuey, 1888 (Kenya), Saprinus rhytipterus Marseul, 1862 (Gabon), Hister amphystrius Marseul, 1880 (Gabon), Atholus chariensis (Desbordes, 1916) (Gabon), Atholus cycloides (Burgeon, 1939) (Gabon), Atholus ruptistrius Lewis, 1913 (Kenya) and Hololepta optiva Lewis, 1914 (Gabon). Key words: Coleoptera, Histendae, Hister sindarae n. sp., Taxonomy, Distribution, Afrotropical region.
