Wing (fig. 55e): Hyaline, unmarked, veins slightly brownish; IRC small, sometimes poorly formed, vein R4+5 thickened from base of IRC to tip of 2RC; CR ; r-m to stem lengths as 7:17; anal angle obtuse; alula with fringe lacking on proximal half; macrotrichia con- fined to a row close to margin between 2RC and tip of vein Mi. Halter slightly Figure 55.—Stilobezzia insolita, new species (9 ). a, frontovertex; b, last 1 tarsomeres and claws; c, palpus; d, 9 genitalia; e, wing;/, spermathecae; g, abdominal terga I-IV. Abdomen (fig. 55g): Pale brownish, tergum I and extreme distal terga yellowish brown; distal segments with definite tapering con- formation; I with 3 setae on each side; I I-IV with sparse setae in a caudal row on each tergum. Spermatheca (fig. 55/), 1, peculiarly re- tort-shaped to unequally U-shaped, with slender, long, sclerotized neck; main portion measuring mm by mm. Genital sclerotization as in figure 55d. Male.—Unknown. Distribution.—Malaya. Types.—Holotype female, Kuala Lumpur, Selangor, Malaya, July 1958, R. Traub, light trap (USNM 69456). Paratypes, 2 females. MALAYA: Pahang, Kuala Singgora, 18 July 1958, R. H. Wharton, light trap, 1 female. Selangor, same data as type, but 12 June, 1 female. Discussion.—This species is set off distinctly by the wide eye separation, the reduced anal angle of the wing, and the fringe on the alula, as well as the poorly developed IRC and thickened R4+s; the long sharp fe
