Diagnosis

Body length 1.6 mm, wing length 1.4 mm. Palpus yellow. Thorax black. Acrostichal and dorsocentral bristles extending to base of scutellum. Legs almost wholly yellow, only tarsomere 5 of all legs and tarsomere 1 of hind leg brownish. Mid femur slender; with 1 black posteroventral spine beyond middle and row of 7 moderately long, spine-like bristles in basal part, 1 long, yellowish bristle near base. Mid tibia with row of black ventral spinules. Hind femur (viewed laterally) evenly thickened toward middle, with at least 5 moderately long anteroventral bristles in apical part. Wing normally developed, more or less evenly infuscate. R 2+3 present, about 2.5 times longer than Rs. Distance between apices of R 2+3 and R 4+5 subequal to distance between apices of R 1 and R 2+3. R 4+5 and M 1+2 divergent and evenly arcuate in apical part. Abdominal gland-like structures present between tergites 2-3 and 3-4. Male terminalia with upper lobe of left surstylus bearing markedly developed surstylar comb. Female similar to male, except mid femur with 3 longer, yellow ventral bristles; mid tibia lacking black ventral spinules; abdominal gland-like structures absent.

Distribution

Cambodia.

Habitat and seasonal occurrence

No data on habitat, only known from January.

Remarks

Currently, S. angkorensis  is known only from Cambodia. However, its occurrence in Singapore is quite possible. This species belongs to the S. divergens  group and is comparable to S. goesi  (also described from Cambodia), but can be distinguished as given in the key.
