Key to species of Stenopsoides

1. Tegmen covered with brown or black fine dots ( Figs 1B , 4A–B ); body length (including pronotal extension) less than 6 mm ............................................................................ S. punctatus Semeraro sp. nov.

- No brown dots on tegmen or if present then confined to the costal cells; body length (including pronotal extension) 6 mm or greater.............................................................................................. 2

2. Pronotal extension with brown or black stripes laterally on both sides, apex of pronotum slightly expanded dorsoventrally ( Figs 1D,L , 2A–B ); tegmen costal cells with brown or black fine dots ( Fig. 2A ); tegminal veins mostly yellow or pale brown; anteclypeus yellow ( Fig. 2D )................................................................ S. turneri Evans

- Pronotal extension without a pair of lateral brown/ black stripes, at most a single diffuse brown dorsal stripe, apex conical and tapering/ rounded at tip or parallel-sided and truncate ( Fig. 1A,C,J,K ); tegmen without any brown or black fine dots; tegminal veins yellow but may be orange at the base of costal margin; anteclypeus reddish/ orange or at least orange at the apex ( Fig. 1E,G ).............................................................................................. 3

3. Pronotal extension lateral margins almost parallel-sided and truncate at apex, brown/ black marking at apex ( Figs 1K , 5C–D ); scutellum dark yellow/ orange, with some concolorous pitting ( Fig. 5B ); distance between coronal pits, equal/ subequal to interocellar distance............................................................... S. truncatus Semeraro sp. nov.

- Pronotal extension tapering and rounded at apex, with brown diffuse dorsal longitudinal stripe ( Figs 1J , 3A–C ); scutellum bright pale yellow and unpitted; distance between coronal pits slightly greater than inter-ocellar distance................................................................................................ S. newi Semeraro sp. nov.
