RIASSUNTO
Abstract
The African species of the genus Laccophilus Leach, 1815, are revised, on the basis of study of adult specimens. In all, 105 species are now recognized. A phenetic character-analysis was undertaken, which resulted in a split of the genus into 17 species groups. Diagnoses and a description of each species are given together with keys for identification of species groups and species. We also provide habitus photos, illustration of male genitalia and distribution maps for all species. New species are described as follows: Laccophilus grossussp. n. (Angola, Namibia), Laccophilus rocchiisp. n. (Tanzania, Namibia, Botswana, Mozambique), Laccophilus ferrugosp. n. (Mozambique), Laccophilus furthisp. n. (Madagascar), Laccophilus isambertisp. n. (Madagascar), Laccophilus inobservatussp. n. (Gambia, Senegal, Mali, Niger, Sudan, Chad, Ethiopia, Burkina Faso, Ivory Coast, Ghana, Nigeria, Cameroon, Zaire and Asia: Yemen), Laccophilus cryptossp. n. (Zaire, Mozambique, Zimbabwe, Namibia, Botswana, South Africa), Laccophilus enigmaticussp. n. (Nigeria, Sudan), Laccophilus bellussp. n. (Benin, Nigeria), Laccophilus guentherisp. n. (Guinea, Ghana), Laccophilus guineensissp. n. (Guinea), Laccophilus decorosussp. n. (Uganda), Laccophilus empheressp. n. (Kenya), Laccophilus inconstanssp. n. (Guinea, Ivory Coast, Ghana, Nigeria, Cameroon), Laccophilus brancucciisp. n. (Central African Republic), Laccophilus incomptussp. n. (Cameroon), Laccophilus australissp. n. (Tanzania, South Africa), Laccophilus minimussp. n. (Namibia), Laccophilus eborissp. n. (Ivory Coast), Laccophilus insularumsp. n. (Madagascar), Laccophilus occidentalissp. n. (Gambia, Senegal, Mali, Guinea, Sierra Leone, Ivory Coast, Ghana, Benin, Nigeria, Central African Republic, Zaire) and Laccophilus transversovittatussp. n. (Madagascar). Laccophilus restrictus Sharp, 1882, is restored as good species; not junior synonym of Laccophilus pictipennis Sharp, 1882.
