Treatment

Mesembrinella bicolor species-group

Recognition. Anterior spiracle with broad oval opening above; disc of T5 without horizontal row of stout setae.

Male with epandrium moderate in size; surstylus and cercus in close proximity, tending to curve toward each other in lateral view (as in Fig. 63 View FIGURES 63–68 ); only M. longicercus has both surstylus and cercus straight ( Fig. 77 View FIGURES 75–80 ). Surstylus usually with a distinct curve posteriorly, whereas the cercus is fairly straight except for forward-curving tip; phallus broad in dorsal view anterior to hypophallic lobes (as in Fig. 154 View FIGURES 153–162 ); sternites typically broader at base (ST1) and usually progressively narrower and smaller distally (ST2–4), with ST5 bilobed as in Fig. 262 View FIGURES 252–265 [in a few species, segments ST1–4 are about of equal width, Fig. 278 View FIGURES 266–279 ]; T4 and T5 about equal in length.
