Figs 42–43

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 .

MESOSOMA. Integument black. Scutum relatively regularly and densely (i = 0.5–1 d) punctate; surface between punctures smooth and shiny ( Fig. 42B ). Propodeum completely areolate ( Fig. 42C ). Scutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with long, brownish to greyish, erect hair.

METASOMA. Integument brownish-black, marginal zone yellowish-brown. Disc of T1 without hair ( Fig. 43A ), T2–T4 basally greyish, dense, short, erect hair band, covering third to half of terga, which covers less of tergum the farther posterior it is. T3–T4 anterior of premarginal line laterally row of short, erect, greyish hair ( Fig. 42D ). T2–T4 basally more densely (i = 0,2 d) and much finer punctate than apically (i = 1–4 d) ( Fig. 42D ); dense punctation covers more than half of T2 ( Fig. 43A ); less than 15 points medially on T2; T2–T3 anterior of premarginal line with row of points; surface between punctures smooth and shiny ( Fig. 42D ).
