Holotype male. Face and clypeus, black, front and vertex black 

 with a trace of dark greenish color; pronotum, sides of thorax and 

 sides of propodeum black, the dorsum of thorax and propodeum a 

 coppery green; abdomen black with sides of first tergite yellowish; 

 inner orbits from clypeus to just above antennae broadly white; 

 apex of mandibles reddish, mouth parts brown, first four joints of 

 antennae reddish yellow, rest lost; coxae all black, fore trochanters 

 yellow, last two pairs black; all femora and tibiae yellow, the basal 

 joints of all tarsi yellow except apex of last two pairs darker; last two 

 joints of foretarsi and last four joints of middle and hind tarsi, dark; 

 about the middle third of clypeus projecting beyond the sides, each 

 side rather deeply concave, the front edge of clypeus thickened; 

 the clypeus and face strongly silvery sericeous; clypeus slightly more 

 than 2.0 broad as long; ratio of lengths of third and foiu-th antennal 

 joints is 10:10 upper interocular distance (12) equal to the lower; 

 head 1.2 as broad as long; wings hyaline; veins and stigma yellow; 

 the basal vein in forewings basad of transverse by about 0.75 the 

 length of latter, in rear wings the subdiscoidal basad of cubital by 

 about same length; parameres of genitaha of the broad heavy type, 

 somewhat acute at apex, free of hair except a few at apex; volsellae 

 short and the apex with more of a V-shaped concavity instead of the 

 more general U-shaped type; parapenial lobes slender on basal 0.75 

 with the apical 0.25 much broadened; subgenital plate with the raised 

 basal triangular surface very broad at base, the triangle closed about 

 apical fourth, a narrow ridge from there to apex. 



Length head and thorax 4.0 mm., abdomen 4.0 mm., forewing 

 6.3 mm., rear wing 4.6 mm. ; length genitalia 0.93 mm., width 0.53 mm., 

 length subgenital plate 0.93 mm., width 0.55 mm.
