Figs 13–14
Diagnosis
The male of S. convexoides sp. nov. can be separated from that of all other species of this group by the following character combination: dense (i = 0.3 d) punctation of discs of T1–T4 (Fig. 13D); dense (i = 0.3 d) punctation on disc of T2 covers more than half of the tergum (Fig. 14A); each tergum curved from anterior to posterior (Fig. 13A) and form of S7 (Fig. 14C). The female is unknown.
Etymology
The name refers to the conspicuously (in lateral view) convex metasomal terga of the male.
