Diagnosis

The female of S. flavipunctatus sp. nov. can be separated from that of all other species of this group by the following character combination: metanotum partly yellowish; T3 anterior of premarginal line impunctate ( Fig. 70E ); coarse punctation on metasoma ( Fig. 70E ); no basal hair bands on T3–T4 ( Fig. 70E ); supraclypeal area delimited by sharp edges ( Fig. 70B ). The male is characterized by hairs on the apicolateral lobes and form of S7 ( Fig. 70C ), narrow basal part of T2 haired and finely, dense (I> 1 d) punctate ( Fig. 72A ), major part of front femur and tibia yellowish ( Fig. 71A ).

Etymology

Named after the unique yellow spot on the metanotum of the female.

Female

BODY LENGTH. 6.9–7.1 mm.

HEAD. Wider than long. Integument brownish, mandibles dark brownish to reddish. Face irregularly and sparsely covered with brownish hair, more densely around basis of antennae. Ocelli slightly in front of posterior margin of compound eyes. Clypeus medially with shallow longitudinal depression; punctation fine and sparse (i = 2–4 d); surface between punctures smooth and shiny ( Fig. 70B ). Malar area medially narrow, slightly curved. Antennal flagella ventrally yellow, dorsally black. Supraclypeal area delimited by sharp edges and with dispersed punctation.

MESOSOMA. Integument black, scutum, scutellum and part of metanotum yellowish-brown, pronotal lobe lighter than integument ( Fig. 70C ). Scutum coarsely and irregularly punctate (i = 1–3 d); surface between punctures smooth and shiny ( Fig. 70C ). Metanotum less than half as long as scutellum. Propodeum completely coarsely areolate ( Fig. 70D ). Scutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with short, brownish to greyish, erect hair.

WINGS. Yellowish-brown, stigma and wing venation brownish ( Fig. 70A ).

LEGS. Integument brownish, fore tibia with yellow spot. Vestiture greyish-white, scopa greyish to brownish, partly black ( Fig. 70A ).

METASOMA. Integument brownish, marginal zones yellowish-brown shimmering. T2–T3 laterally with sparse, short, brownish-grey, erect hair; T4 completely sparsely haired; T3–T4 anterior of premarginal line with row of hairs; prepygidial and pygidial fimbriae greyish-brown ( Fig. 70E ). Disc of T1 sparsely (i = 1–3 d) and finely punctate; basally on T2 more densely (i = 1 d) punctate than disc (i = 1–3 d); disc of T3 completely sparse punctate (i = 1–3 d); surface between punctures smooth and shiny ( Fig. 70F ).

Male

BODY LENGTH. 7.3–7.6 mm.

HEAD. Wider than long. Integument brownish-black to black, mandibles dark brownish to reddish. Face densely covered with long, white, erect hair. Ocelli in front of posterior margin of compound eyes. Malar area medially narrow, slightly curved. Antennal flagella ventrally yellow, dorsally black.

MESOSOMA. Integument black, pronotal lobe brownish. Scutum irregularly and sparsely (I <1 d) punctate; surface between punctures matt ( Fig. 71B ). Propodeum completely coarsely rugulose-areolate ( Fig. 71C ). Scutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with long, brownish to greyish, erect hair.

WINGS. Yellowish-brown, stigma and wing venation brownish ( Fig. 71A ).

LEGS. Integument brownish, fore and mid tibia with yellow spot of different sizes; fore legs often generally lighter than other legs. Vestiture greyish-brown ( Fig. 71A ).

METASOMA. Integument brownish, marginal zones yellowish-brown. Disc of T1 without hair ( Fig. 72A ), T2–T4 basally narrow, greyish-brown, dense, middle-long, erect hair band. T2–T4 laterally sparsely, but long haired. T3–T4 anterior of premarginal line at least laterally row of short, erect, greyish hair ( Fig. 71D ). Disc of T1 finely and relatively sparsely (i = 2–4 d) punctate ( Fig. 72A ); discs of T2–T4 basally more densely (i = 1 d) and finer punctate than apically (i = 2–3 d); surface between punctures matt ( Fig. 71D ).

TERMINALIA. Genitalia ( Fig. 72B ), S7 ( Fig. 72C ) and terminal plate of S8 ( Fig. 72D ) as illustrated.
