Diagnosis

The female of S. atricapillata sp. nov. can be separated from that of all other species of the genus by the combination of the following characters: S6 bifid posteriorly, apical notch about as long as its apical width, shape as shown in Fig. 34C; body length 7–9 mm; metasoma partially red (Fig. 33B); fore tibia and tarsi usually black (Fig. 33A); T6 covered with black hair (Fig. 34B); head and mesosoma with conspicuously dense, long, black hair (Fig. 33C–D); T5 with black hair on the disc and bright white hair on the apical margin (Fig. 34B); T6 apically slightly rounded (Fig. 34B); mesoscutum very densely punctate (i =0–0.25 d), surface appears rugged (Fig. 33D). The male can be separated from that of all other species of the genus by the combination of the following characters: metasoma at least partially red (Fig. 35B); fore legs usually black (Fig. 35A); head and mesosoma with conspicuously dense, long, black hair (Fig. 35C–D); mesoscutum more finely punctate (Fig. 35D); gonostylus shorter than gonocoxa and apically broader (Fig. 36C–D); penis valves less distinctly curved downward (Fig. 36C–D).

Etymology

The species is named for its conspicuous black hair.
