Papp, L.: Two new genera of the Oriental Sphaeroceridae (Diptera)

Pellucialula gen. n. Type species - Pellucialula polyseta sp. n. Gender - Feminine. Description - A robust fly with numerous perpendicular macrotrichia on both sides of the wing (on the upper (radial) part) (Fig. 11 ). The other characters of the species are as follow: Eyes large. Lateral arista, long aristal cilia, weak poc but 2 pairs of strong occipitals, strong genal bristle, no inner orbitals. Three or four short pairs of dc in front of the longer posterior de. A third, basal pair of scutellars present. Costal vein without erect perpendicular hairs but costal hairs dense and rather long even distally to R,. No strong basal (costagial) seta. Vein R

4+5 slightly bent up to costa, costal vein ending at R

4+5 (Fig. 11 ). Medial and cubital veins continue over dM-Cu only by very short faint vein shadows, but anal vein reaching wing margin or nearly so. Alula large. Short and flattened tarsomeres, particularly so for the hind leg. A complete row of strong anterodorsals on mid tibia (posterodorsals much weaker). No mid ventral seta on mid tibia. No ventro-apical seta on mid tibia of male (present in female) but a ventral seta on mid basal tarsomere plus rows of other thick setae there, short thick ventral spur on hind tibia. Male sternite 5 with a strongly sclerotized small black plate (Figs 14-15), which is ventral to sternite 5 (and it seems rather disconnected and movable up and down). Medial part of sternite 6 with a patch of small pointed black thornlets, which cover partly also membrane. Nothing special in male genitalia: long hypandrium and phallapodeme (Fig. 17), hypandrium without ventral appendages, short phallus, extremely long but only apically curved postgonite (Fig. 18), rather strong epiphallus (Fig. 17).
