2. Aplomerus robustus Townes and Townes, new species 



Male. Front wing 3.0 to 6.5 mm. long; temple long, most of it 

 weakly rounded but posteriorly rather strongly rounded to the 

 occipital carina; punctures on temple coarse, separated by about 0.5 

 their diameter; first abdominal tergite 3.2 to 3.9 as long as wide, its 

 basal half with sharp median longitudinal carinae between which it is 

 weakly concave, most of its surface covered with close, moderately 

 fine, longitudinal wrinkling; second tergite covered with fine, rather 

 regular, sharp longitudinal wrinkles; third tergite with finer, less 

 distinct longitudinal wrinkling that covers its basal 0.8 ± ; fourth and 

 fifth tergites with some very fine irregular transverse wrinkling. 



Black. Palpi light brown; tegula brown; front and middle legs 

 varying from light fulvous to blackish brown, their coxae always 

 more or less fuscous or black, their trochanters usually infuscate at 

 least basally, and their tarsi infuscate apically, hind coxa blackish; hind 

 trochanters light brown to blackish; hind femur dark brown to black, 

 its base and extreme apex usually paler; hind tibia and tarsus dark 

 brown; wings subhyaline. 



Female: Front wing 4.7 to 9.0 mm. long; body, especially the 

 abdomen, unusually stout; flagellum with 25 to 29 segments; head not 

 strongly depressed, about 0.84 as high as long; temple moderately 

 rounded, not distinctly bulged; punctures on temple coarse, sub- 

 adjacent, tending to be confluent in irregular rows that result in weak 

 rugose furrows; notaulus foveolate; propodeal areola with strong 

 bounding carinae, lateral propodeal areas strongly rugose; first 

 abdominal tergite uniformly convex or medially with a faint flatten- 

 ing, its surface covered with fine, irregular longitudinal wrinkles; 

 tergites 2-4 with fine but sharp striae on all but their polished apical 

 margins ; striae on tergite 2 longitudinal basally, oblique lateroapically, 

 and irregularly transverse medioapically ; striae on tergite 3 transverse 

 but medially with a gentle curve; striae on tergite 4 transverse; fifth 

 and following tergites with progressively finer and failing transverse 

 striae; ovipositor sheath about 1.4 as long as front wing. 



Black. Palpi dark fulvous; tegula dusky ferruginous; legs and 

 abdomen ferruginous, the basal tergite sometimes partly infuscate; 

 ovipositor sheath fulvous, its apical expanded part brownish fulvous; 

 wings weakly infuscate.
