Diagnosis
The male of S. perpunctatulus sp. nov. can be separated from that of all other species of the thus group by the following character combination: dense (i = 0.2 d) and irregular punctation basally on T2–T4 (Fig. 42D), dense punctation covers more than half of T2, less than 15 points medially of terga (Fig. 43A); basal hair bands on T3–T4 coarse and long (Fig. 44D). The female is unknown.
Etymology
The name refers to the morphological similarity to S. perpunctatus.
