Dashymeniella Poppius 1914a: 53 [gen. nov.], type species by monotypy: Dashymeniella tibialis Poppius, 1914 Dashymeniella: Carvalho 1955: 18 [key to genera], 1957: 27 [catalog]; Schuh 1995: 24 [catalog]; Gorczyca 2000: 47 [list]; 2006: 12 [catalog]

Diagnosis. Dashymeniella can be recognized by the following set of features: body suboval, small (usually <3.5 mm); dorsum strongly shinning, nearly devoid of setae or covered with sparse vestiture; head sparsely punctate or rugose ( Fig. 46 ); apex of frons somewhat swollen ( Fig. 46 ); clypeus separated from frons by moderately deep, short, transverse incision; clypeus narrowed towards apex, convex basally; antenna thin; antennal segment I narrowed at basal one fourth ( Figs. 94 ), covered with very sparse setae, sometimes almost devoid of vestiture ( Fig. 94 ); segment II usually weakly thickened towards apex, covered with moderately dense setae, being sparser basally ( Fig. 95 ); pronotal calli distinct, usually flattened and inpunctate ( Figs. 13–17 ); scutellum usually with medial inpunctate shining swelling ( Figs. 13–17 ); metepisternum deeply and densely punctate ( Fig. 53 ); ostiolar peritreme characteristically convex, rounded, devoid of microtrichae, and shining; cuneus strongly reduced, much shorter than its width ( Figs. 13–17 , 89 ); membrane with major cell rounded apically ( Fig. 88 ); tibiae with whitish or yellowish apical annulation; DSS usually stout, strongly broadened apically; AES, MES and PES usually present and well developed ( Figs. 96, 99, 102, 105 ).

Most similar to Leprocapsus in having similar structure of the head, the antennal segment I, the metepisternum, and the ostiolar peritreme. Dasymeniella can, however, be distinguished by the smaller size, the moderately convex pronotal calli, the medial swelling of the scutellum less distinctly elevated, the cuneus distinctly reduced, and the membrane with the major cell broad and rounded apically.
