Head with the interocular space on vertex in $ as broad as ocellar tubercle, in $ a little more than 2 times width of tubercle; frons without a distinct, or even shallow, central depression in £, but with a very shallow one in $; facial cone conically projecting; antennae with joints 1 and 2 short, but with 1 slightly longer and broader than 2, joint 3 more or less shaped like that of psammophila, narrowed from a broad base, but. Text-fig. 28. Side and ventral views of hypopygium of $ Plesiocera rufiventris n. sp. with the apical part distinctly more marked off as a slender part; proboscis about 1-1-4 mm- long> confined to buccal cavity. Legs without any spines visible on front and middle femora in & the middle ones in $, however, with about 4 minute apical ones; hind femora with about 4 separated spines on outer apical aspect, of which the apical one is the longest; front tibiae without any visible spicules; front claws reduced, but not the same extent as in flavilabris and curvistoma. Hypopygium of <£ (text-fig. 28) with the beaked apical joints elongate, narrowish, slightly laterally compressed, ending apically in an upturned, sharp point, the joints slightly S-curved when viewed from above (see dorsal view in middle)
