near its middle; second tergite subpolished, its basal 0.25 ± with 

 moderately strong, mostly longitudinal wrinkling, its pimctures small, 

 moderately sharp, on median part of tergite very sparse and separated 

 by about 1.5 to 3.0 the length of the hairs, marginally denser and 

 more regularly distributed, separated by about 0.8 the length of the 

 hairs. 



Coloration as in the female. 



Female: Front wing 4.4 to 9.5 mm. long; flagellum with about 39 

 segments, its first segment about 1.35 as long as second; head about 

 0.98 as wide across temples as across eyes; punctures on temple 

 moderately small, separated by about 3.0 their diameter; thorax 

 about 2.26 as long as high; upper 0.2 ± of pronotum with some small 

 punctures that are separated by about 3 times then* diameter; trough 

 of pronotum smooth; epomia absent or very weak; mesoscutal punc- 

 tures fine, separated by about 5 times their diameter; mesepimeron 

 with hairs on its upper 0.8 ±; metapleurum rather coarsely rugoso- 

 punctate; petiolar area about 0.57 as long as combined areola and 

 basal area; propodeal teeth about 0.9 as long as then* basal width; 

 hairs in first lateral area sparse, their sockets separated by about 1.2 the 

 length of the hairs; hind femur about 2.10 as long as deep, the punc- 

 tures on its upper 0.4 ± of moderate size, moderately strong, closely 

 spaced, on its lower 0.6 the pimctures very sparse, separated by about 

 5 times their diameter; second segment of middle tarsus about 2.0 

 as long as deep; fifth segment of hind tarsus about 1.35 as long as 

 second segment; second tergite mostly smooth and polished but its 

 basal 0.3 ± partly rugulose and finely wrinkled, the wrinkles at 

 extreme base transverse, the rest mostly longitudinal; punctures on 

 second tergite very small, separated by about 3 times the length of 

 the hairs; ovipositor sheath about 1.50 as long as front wing. 



The female is distinguished by the black abdomen, pale fulvous 

 legs, fuscous apex of hind femur, pronotal trough without trans- 

 verse wrinkles, sparse punctures on lower part of hind femur, and 

 second segment of middle tarsus about 2.0 as long as deep.
