BMNH, United Kingdom. S y n o n y m s: givenbyGRAHAM (1969), NOYES (2017). D i a g n o s i s: ♀: Antenna (Fig. 1 n) with anelli plus F 1 2.4 x as long as pedicellus; F 1 2.21 x as long as width; F 2 slightly longer than width; F 3 quadrate; F 4 slightly, F 5 - F 6 distinctly transverse. club 0.88 x as long as F 1. Malar space hardly one third length of an eye; Forewing (Fig. 3 n) with stigmal vein forming an less acute angle 40 o with the postmarginal vein; costal cell of fore wing 10.5 - 11 times as long as broad; sometimes relatively longer; submarginal vein 1.63 x as long as marginal vein; marginal vein 1.57 x stigmal vein; post marginal vein equal to marginal vein. Propodeum with transverse costula, median and plicae. Metasoma 1.3 x longer than as mesosoma. Antennal scape and pedicel pale, flagellum dark; mesosoma black, forewing with black spot; Metasoma often with a pale transverse band on the basal tergite, sometimes the whole base yellowish. Legs with coxae and femora mostly black, concolorous with body, at most tips of femora and tibiae and tarsi pale coloroud. ♂: Similar to ♀ except as follows: Antennae (Fig. 2 f; Fig. 289 of BOUCEK & RASPLUS (1991) with all 9 flagellar segments separated by peduncles, therefore no club is differentiated; combined length of pedicel and flagellum 2.1 - 2.75 times the breadth of the head; segments of funicle elongate, the first 3.5 - 5.5 times, the seventh 1.8 - 3.0 times as long as broad; scape 11, in anterior view its anterior margin distinctly convex, posterior margin almost straight; distinctly expanded in its upper half, where there is a distinct shiny boss on its outer aspect; pedicel 1.5 x as long as wide and 0.26 x as long as F 1; flagellum 70, 6.36 x length of scape, filiform; funicular segments gradually decreasing in length, F 1 11.5; F 2 9; F 3 7.5; F 4 7; F 5 7; F 6 6.5; F 7 5, 2.5 x as long as wide; F 8 4.5; F 9 6 (= club 1 segmented), acuminate, short, 0.52 x as long as F 1; linear sensillae on F 1 5, in 3 rows; F 2 - F 9 4 in 2 rows, (3 apically 1 medially); Fore wing with costal cell 10 - 13 times as long as broad; speculum sometimes effaced by scattered hairs; Fore wing with speculum, on lower surface of wing, more or less effaced by scattered hairs; basal cell partly, sometimes entirely, pilose. Larger species, up to 3.1 mm. Diagnostic characters were created from WALKER (1835), GAHAN (1933), GRAHAM (1969) and Figure 289 of BOUCEK & RASPLUS (1991).
