Review of Namibian material

Until recently, very little information was available with respect to the Namibian Dolichopodidae. Twenty species were recorded and described in recent reviews of Afrotropical genera and subfamilies of the family (Grichanov 1996-1999). The majority of species have been collected in the central arid part of the country, being xerophilous and halophilous by nature. Some of these species are widely distributed across semi-deserts or maritime territories of the Old World (Amblypsilopus munroi (Curran, 1924), Hydrophorus praecox Lehmann, 1822, Tachytrechus tessellatus (Macquart, 1842), Thinophilus indigenus Becker, 1902). The remaining are regarded as being endemic to Namibia (Medetera chumakovi Grichanov, 1997, Medetera rikhterae Grichanov, 1997, Thinophilus munroi setiscutellatus Grichanov,1997) or to southern part of Africa (Cemocarus griseatus (Curran, 1926), Hydrophorus vaalensis Parent, 1954, Medetera norlingi Grichanov, 1997, Medetera polleti Grichanov, 1997, Medetera subchevi Grichanov, 1997, Condylostylus imitator Curran, 1924). Namibia as a whole and north-eastern parts of the country (Kwando river basin) has a significant tropical element, with many species common with central Africa or occurring across the continental Afrotropics. To date I have examined about 50 species of the family collected in Namibia, some of which should be described as new taxa, but the real number may reach 100-200 species following a special expedition covering a wider geographical area of the country. First records of a species from Namibia are marked with (!).
