ÁBRAHÁM, L. & DOBOSZ, D.: ANT-LION AND OWL-FLY FAUNA OF MADAGASCAR 123 Vise a mutila Navás, 1927 (Fig. 5.) Visca mutila Navás, 1927 - Navás, 1927 (Odescr), Marki 1954 (Morph), Penny 2003 (Chlist), 2006 (Chlist, Dist), Stange 2004 (Mon). Chabalus ineptus Navás, 1935 - Navás 1935 (Odescr), Stange 2004 (Syn). Material examined: In Coli. USMB: [Prov. Toamasina,] Antsahatsaka 5 km of Moramanga 9-11. 12. 1999 1$ leg. J. Stolarczyk 5858/1182. Comment: It is an endemic and rare species. STANGE (2004) listed the genus of Visca Navás, 1927 in the tribe of Nemo/eontini Banks, 1911 and in the subtribe of Neuroleontina Navás, 1912 but we agree with ASPÖCK et al. (2001) and KRIVOTHATSKY (1998) who assigned that genus for Glenurini Banks, 1927. It is an endemic genus with two known species ( STANGE 2004) in the island of Madagascar. Genera of Chabalus Navás, 1935 and Belelion Auber, 1955 are synonymised by STANGE (2004). The genus of Visca is characterized by A2 forked, A3 simple on the fore wing and CuP+Al almost parallel with hind margin on both wings. The costal area of fore wing is simple, there are 1-3 radial cross-veins in the front of origin of Rs on the hind wing. No pilulla axillaries can be found at the base of male's hind wing. The pronotum is longer than wide. There are no tibial spurs on long legs. Male ectropoct is an oval plate. Distribution: Prov. Antananarivo, Toamasina. Visca magnus Ábrahám sp. n. (Fig. 6.
