Figs 17–18

Diagnosis

The female of S. acuta sp. nov. can be separated from that of all other species of the genus by the combination of the following characters: S6 bifid posteriorly, tips barely curved inward, apical notch with a small tip distally, shape as shown in Fig. 18C. Body length max. 5.3 mm; metasomal terga T1–T2 red (Fig. 17B); fore tibia and tarsi usually black (Fig. 17A); T6 covered with black hair (Fig. 17B); head and mesosoma with shorter black hair and more dispersed punctation (Fig. 17C–D); propodeum covered with short, white hair only (Fig. 18A); mesoscutum more finely and densely (i=0.25–0.5 d) punctate (Fig. 17D). The male is unknown.

Etymology

The name refers to the unusual thin and needle-like sharp tip of the female S6.
