NEW RECORDS OF PREDATORY LONG-LEGGED FLIES FROM THE REPUBLIC OF GUINEA (DIPTERA: DOLICHOPODIDAE) WITH DESCRIPTION OF SIX NEW LICHTWARDTIA SPECIES

Six new long-legged fly species, Lichtwardtia aurocuprea sp. n., Lichtwardtia caeruleifacies sp. n., Lichtwardtia sychevae sp. n., Lichtwardtia nudicauda sp. n., Lichtwardtia argentifacies sp. n. and Lichtwardtia ripariensis sp. n., from Faranah and Labé provinces of Guinea, are described and illustrated. Males of the new species differ from others in face colour, postpedicel shape, sometimes modified wing costa and features of the male genitalia. In addition, seven new species records are listed for the Republic of Guinea, including four species reported from the country for the first time: Amblypsilopus auratus (Curran), Chaetogonopteron nectarophagum (Curran), Condylostylus beckeri Speiser and Pseudoparaclius zogualensis (Grichanov). Lichtwardtia nikolaevae Grichanov, 1998 is placed in synonymy with L. microlepis (Parent, 1939). A list and a key to West African Lichtwardtia species are compiled. As a result, the dolichopodid species number in the Guinean fauna has increased to 25, the World fauna of the genus Lichtwardtia contains now 47 species, and its Afrotropical fauna has increased to 29 species.
