Dashymenia Poppius

( Figures 5–12 , 44–45 , 50–51 , 55–86 )

Dashymenia Poppius, 1910: 170 [gen. nov.], type species: Dashymenia convexicollis Poppius, 1910 (original designation) Dashymenia: Carvalho 1955: 17 [key to genera], 1957: 27 [catalog]; Schuh 1995: 24 [catalog]; Gorczyca 2000: 47 [list], 2006: 11 [catalog]

Dasymenia: Bergroth 1920: 69 [unnecessary emendation]

Diagnosis. Body elongate oval to suboval ( Figs. 5–12 , 55 , 64 ), usually larger than 4.5 mm; dorsum shining, covered with long, dense vestiture; head moderately rugose ( Figs. 44–45 ); antenna shortened ( Figs. 5–12 ); antennal segment I cylindrical along entire length, weakly narrowed basally ( Figs. 55 , 64 , 74 ); segment II stout ( Figs. 5–12 ), covered with dense vestiture ( Figs. 74–75 ); apex of labium reaching beyond apex of procoxae ( Fig. 51 ); pronotal calli flattened, not distinctly separated from remainder of pronotum, sometimes absent ( Figs. 5–12 ); scutellum almost flattened or weakly arched, without any medial swelling ( Figs. 5–12 ); metepisternum inpunctate ( Figs. 50–51 , 69–70 ); ostiolar peritreme characteristically rounded, devoid of microtrichae and shiny ( Figs. 71 ); cuneus longer than its width ( Figs. 5–12 , 76, 78 ); endosoma with DSS stout, strongly broadened basally and with full set of other sclerites ( Figs. 39 , 57–58, 60–61 , 80, 84 ).

Dashymenia is most similar to Bakeriola in sharing inpunctate metepisternum. This genus can, however, be distinguished by the flattened, indistinct pronotal calli.
