Cicinnoscelis Holland, 1893 rev. stat. Type species: Cicinnoscelis longipes Holland 1893: 183, by original designation. Literature. Hampson 1919: 78 (as Cicinoscelis [sic]); Dalla Torre & Strand 1925: 120 (as Cicinoscelis [sic]); Naumann 1971: 14; Heppner & Duckworth 1981: 42; Fletcher & Nye 1982: 38; Pühringer & Kallies 2004: 43. The poorly known genus Cicinnoscelis was considered synonymous with Alonina for many years (sensu Hampson 1919). However, significant differences of the antenna, the wing venation and the structure of the genitalia do not support a close relationship to Alonina. The type species Cicinnoscelis longipes Holland, 1893 rev. comb. from Gabon is only known in the male sex. It seems closely related to and may well be congeneric or even conspecific with Megalosphecia gigantipes Le Cerf, 1916 from Cameroon, the type species of Megalosphecia Le Cerf, 1916, which is solely represented by females. Both species share important structural characters, namely the large size, the long, clavate antennae, the very long and tufted hind legs, the opaque, blackish wings and the rather similar wing venation. The exact relationship of Cicinnoscelis and Megalosphecia could not be definitively clarified. Both genera are here placed in Sesiini for the first time. The following redescription of Cicinnoscelis based on two males of Cicinnoscelis longipes from Eala (Fig. 1) and Bamanya, Congo, which are deposited in MRAC, and two females from southern Africa, below described as Cicinnoscelis flavipes new sp. and C. krooni new sp. Redescription. Very large clearwing moths with long, slender, tufted hind legs, wingspan varies from 45 to 64 mm. Head with labial palpus moderately upturned, covered with short and ventrally rough scales, third palpomere smooth, second palpomere about three times the length of other palpomeres; proboscis reduced; eyes very large, width of frons about equal the diameter of the eye; antenna spindle-shaped, in male bipectinate, rami covered with minute ciliae, in female simple ...
