Genus Dallatorrella Kieffer

Dallatorrella Kieffer, 1911:244 . Type species Dallatorrella rubriventris Kieffer, 1911 , by monotypy.

DIAGNOSIS: Body usually entirely black to dark brown or at least so on mesosoma. Foveate sculpture present on lower face, lateral surfaces of pronotum, and scutellum. Antenna short in both sexes, shorter than the length of head and mesosoma combined; F1 at most 1.7 times as long as wide at midpoint; flagellomeres distinctly swollen submedially. Eyes distinctly protruding laterally beyond temple. Parascutal carinae posterolaterally produced into a triangular process. Scutoscutellar sulcus divided by two or more submedian carinae into three or more foveae; median carina absent. Mesoscutellum at least raised laterally and sometimes also posteriorly; dorsal surface entirely foveate­reticulate or foveate­rugose and without transverse costae. Metapleural sulcus straight to slightly bent at middle, metepisternum subtriangular. M + Cu 1 of forewing run almost parallel basally to R + Sc before turning away abruptly from the latter apically. Procoxa anterolaterally with a vertical carina (figs. 18, 19, 28, 29). Median, ventral hump on petiolar annulus present in females but absent in males. T7–T8 not fused with each other.
