Lateron he located a very robust with 2 rows of apic al spines; ♀ genitalia with similar clearwing species (Fig. 1) in copula twice, once sclerotized an trum, short mem branous ductus bursae, positioned next to a large pupal exuvia protruding from corpus bursae without sig num. mistletoe (Loranthus sp.), apparently the food plant. Differential diagnosis. The ♂ of the new genus is mor One of the ♂♂ unfortunately escaped while trying to pho logically most resembling Alonina Walker, 1856 photograph them. He initially thought they would be from West, East and South Africa, and Melittosesia the same species as the former, but after spreading he Bartsch, 2009, described from Madagascar. Also the realised that the pattern on the thorax is different. wing venation (Fig. 6) is similar, but Cu1 and Cu2 of fw. Both species proved to be new to science and are adjoining each other (in ♂ only). However, genitalia de scribed below. They belong to the tribe Sesiini. are quite different from the latter, with robust gnathos, Despite the close resemblance of the females there are remarkably short valve, the outer half covered with long con si der able morphological differences in antennae and bifurcate setae, phallus with 2 rows of apical spin es. And molecular biology causing serious doubt that both spe the characteristic beardlike tuft of 1st pal po mere in ♀ cies belong to the same genus. It seems likely that this is has never been mentioned in Afro tro pic al Se siini (♀♀ of a case of remarkable morphological convergence. How most species being unknown, however). ever, since the male of one species remains un known and it is not desirable to create a new genus for every new Barbaspheciahephaistos sp. n. (Figs. 1, 3, 4, 6–9) species, both species were placed into one new genus. Holotype ♂: Ghana, Central Region, Kakum Forest, Abra fo Gyawale, 5°21'21.17" N, 1°22'17.70" W, 127 m, 18.–28. ix.
