Figs 75–78

Diagnosis

The female of S. tenera sp. nov. can be separated from that of all other species by the combination of the following characters: S6 bifid posteriorly, apical notch four times as long as its apical width, more or less spatulate, shape as shown in Fig. 76C; body length 3.5–5.8 mm; metasoma partially red (Fig. 75B); fore tibia and tarsi usually black, sometimes with small reddish spots (Fig. 75A); T6 covered with golden hair (Fig. 76B); head and mesosoma with light hair (Fig. 75C–D); propodeum densely covered with short white or yellowish-white hair (Fig. 76A); T5 apically densely covered with short white hair (Fig. 76B); T6 rounded apically, covered with short golden hair forming a fringe (Fig. 76B). 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. 77B); fore legs usually black, sometimes with small reddish spots (Fig. 77A); propodeum covered with white hair (Fig. 77E); head and mesosoma with white hair (Fig. 77C–D); T7 very sparsely covered with short golden hair (Fig. 77F); gonostylus inclined inward, penis valves narrower, slightly shorter than gonostylus (Fig. 78C); S8 broadly rounded apically (Fig. 78B).

Etymology

The name refers to the small and delicate appearance of the species.

Comment

Five specimens display slight morphological differences: in S. cf. 1 tenera sp. nov. the marginal zone of T5 is covered less densely with fewer short, white hairs; T6 is broader, sparsely covered with short, golden hair and more truncate apically without a hair fringe. In S. cf. 2 tenera the marginal zone of T5 is much more densely covered with short, white hair and T6 densely covered with short, golden hair, slightly more truncate apically with a smaller, sparse hair fringe. In S. cf. 3 tenera T6 is narrower and more truncate apically.

At present, the taxonomic status of these specimens is unclear so we do not assign them to S. tenera sp. nov. but make their collection data available to enable further investigation:
