Diagnosis

The female of S. angulata 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 one and a half times as long as its apical width and without a small tip distally, notch wide, shape as shown in Fig. 20C; T 1–T 3 to a variable extent red, from only T1 apical half and T2 basal half red to completely red ( Fig. 19B ); fore tibia and tarsi with small reddish spots ( Fig. 19A ); T6 covered with black hair ( Fig. 20B ); head and mesosoma with short black hair and more dispersed punctation ( Fig. 19C–D ); T6 almost truncate apically ( Fig. 20B ). The male is unknown.

Etymology

The species is named for its conspicuously angular female T6.
