LEPTOPHLEBIIDAE Adenophlebiodes (Adenophlebiodes) massirius ELOUARD-HIDEUX et ELOUARD, 1991 Material examined - GHANA: Northern Region, Banda-Nkwanta, Volta, 2°09'W, 8°22'N, 122 m, 2 $$,07.10.1965 (G089); same locality, 1 $, 01.09.1965 (G070); 1 $,27.09.1965 (G083); 1 $, 09.09.1965 (G072); 3 $$, 01.10.1965 (G088); 4 $$, 13.09.1965 (G073); Ashanti Region, Kumasi, Volta, 1°36'W, 6°43'N, 293 m, 1 $, 31.05.1969 (G365); same locality, 1 $, 25.06.1969 (G377). All collected by S. ENDRŐDY-YOUNGA. Diagnostic features - In the genus Adenophlebiodes ULMER, 1924, the male genitalia do not allow a species-level determination. The diagnosis of the different species is mainly based on the colour pattern on the fore wings and abdomen. The different species were separated into two groups depending on the pigmentation of the basal half of the forewing. In the A. ornatus ULMER, 1916 group, the pigmentation is restricted to patches and margination of crossveins (ELOUARD-HlDEUX & ELOUARD 1991). Adenophlebiodes massirius can be separated from other species of the A. ornatus group by having brown fore femora with a central dark brown spot (fig. 41 in ELOUARD-HlDEUX & ELOUARD 1991), the relatively poorly developed markings on fore and hindwings (figs 18 to 25 in ELOUARD-HlDEUX & ELOUARD 1991) and the absence of a rounded brown marking on the apical half of the forewing (as in A. adrieni ELOUARD-HlDEUX et ELOUARD, 1991, figs 26 to 28 in ELOUARD-HIDEUX & ELOUARD 1991). Distribution - Adenophlebiodes massirius is the most abundant and widespread species of Adenophlebiodes in West Africa. It has already been reported from Ghana as well as from Guinea, Ivory Coast, Mali, Senegal, Sierra Leone and Togo (ELOUARD-HlDEUX & ELOUARD 1991). Adenophlebiodes (Adenophlebiodes) rubeus ELOUARD-HIDEUX et ELOUARD, 1991 Material examined - GHANA: Ashanti Region, Kwadaso/Kumasi, 1°39"W, 6°42'N, 259 m, 1 cj, 04.08.1969 (G224), ENDRŐDY-YOUNGA, S. Diagnostic features - A. rubeus belongs to the A. decoratus (NAVÀS, 1931) species group. As in other species of the group, almost the whole basal half of the forewing is pigmented. The determination of the different species is rather difficult and based mainly on coloration of the thorax and fore femora as well as the number of crossveins in forewing (ELOUARD-HlDEUX & ELOUARD 1991). The problematic determination is amplified by a species only known at the subimaginai stage.
