Abstract [en]

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 grossus sp. n. (Angola, Namibia), Laccophilus rocchii sp. n. (Tanzania, Namibia, Botswana, Mozambique), Laccophilus ferrugo sp. n. (Mozambique), Laccophilus furthi sp. n. (Madagascar), Laccophilus isamberti sp. n. (Madagascar), Laccophilus inobservatus sp. n. (Gambia, Senegal, Mali, Niger, Sudan, Chad, Ethiopia, Burkina Faso, Ivory Coast, Ghana, Nigeria, Cameroon, Zaire and Asia: Yemen), Laccophilus cryptos sp. n. (Zaire, Mozambique, Zimbabwe, Namibia, Botswana, South Africa), Laccophilus enigmaticus sp. n. (Nigeria, Sudan), Laccophilus bellus sp. n. (Benin, Nigeria), Laccophilus guentheri sp. n. (Guinea, Ghana), Laccophilus guineensis sp. n. (Guinea), Laccophilus decorosus sp. n. (Uganda), Laccophilus empheres sp. n. (Kenya), Laccophilus inconstans sp. n. (Guinea, Ivory Coast, Ghana, Nigeria, Cameroon), Laccophilus brancuccii sp. n. (Central African Republic), Laccophilus incomptus sp. n. (Cameroon), Laccophilus australis sp. n. (Tanzania, South Africa), Laccophilus minimus sp. n. (Namibia), Laccophilus eboris sp. n. (Ivory Coast), Laccophilus insularum sp. n. (Madagascar), Laccophilus occidentalis sp. n. (Gambia, Senegal, Mali, Guinea, Sierra Leone, Ivory Coast, Ghana, Benin, Nigeria, Central African Republic, Zaire) and Laccophilus transversovittatus sp. n. (Madagascar). Laccophilus restrictus Sharp, 1882, is restored as good species; not junior synonym of Laccophilus pictipennis Sharp, 1882. New synonyms are established as follows: Laccophilus continentalis Gschwendtner, 1935 = Laccophilus perplexus Omer-Cooper, 1970, syn. n., Laccophilus taeniolatus Régimbart, 1889 = Laccophilus congener Omer-Cooper, 1957, syn. n., Laccophilus adspersus Boheman, 1848 = Laccophilus vitshumbii Guignot, 1959, syn. n. = Laccophilus adspersus nigeriensis Omer-Cooper, 1970, syn. n. = Laccophilus adspersus sudanensis Omer-Cooper, 1970, syn. n., Laccophilus modestus Régimbart, 1895 = Laccophilus espanyoli Hernando, 1990, syn. n., Laccophilus flaveolus Régimbart, 1906 = Laccophilus pampinatus Guignot, 1941, syn. n., Laccophilus trilineola Régimbart, 1889 = Laccophilus simulator Omer-Cooper, 1958, syn. n., Laccophilus mediocris Guignot, 1952 = Laccophilus meii Rocchi, 2000, syn. n., Laccophilus epinephes Guignot, 1955 = Laccophilus castaneus Guignot, 1956, syn. n., Laccophilus saegeri Guignot, 1958 = Laccophilus comoensis Pederzani & Reintjes, 2002, syn. n., Laccophilus restrictus Sharp, 1882 = Laccophilus evanescens Régimbart, 1895, syn. n., Laccophilus incrassatus Gschwendtner, 1933 = Laccophilus virgatus Guignot, 1953, syn. n., Laccophilus cyclopis Sharp, 1882 = Laccophilus shephardi Omer-Cooper, 1965, syn. n., Laccophilus burgeoni Gschwendtner, 1930 = Laccophilus wittei Guignot, 1952, syn. n., Laccophilus secundus Régimbart, 1895 = Laccophilus torquatus Guignot, 1956, syn. n., Laccophilus desintegratus Régimbart, 1895 = Laccophilus sanguinosus Régimbart, 1895, syn. n. and Laccophilus flavopictus Régimbart, 1889 = Laccophilus bergeri Guignot, 1953, syn. n. = Laccophilus segmentatus Omer-Cooper, 1957, syn. n.

Laccophilus remex Guignot, 1952, comprises a species complex with uncertain taxonomic delimitation; the complex includes Laccophilus concisus Guignot, 1953, Laccophilus turneri Omer-Cooper, 1957 and Laccophilus praeteritus Omer-Cooper, 1957, as tentative synonyms of Laccophilus remex Guignot, 1952.
