Diagnosis
The female of S. nigritarsis sp. nov. can be separated from other species of this group by the combination of the following characters: supraclypeal area and clypeus sparsely but distinctly punctate, mostly finely sculptured and slightly matt (Fig. 19 C–D), scutum sparsely but relatively coarsely punctate, basal area of propodeum basally largely carinate (Fig. 19B), stigma brown, apical margins of metasomal terga black or only slightly brownish translucent, terga impunctate (Fig. 19E). The male is characterized by an unmodified antenna, simple and black hind tibia and hind basitarsus (Fig. 20A), almost hairless and impunctate abdominal terga (Fig. 20C) and form of S7 (Fig. 20D).
Etymology
Named for the black tarsi of the females.

Description
Female
BODY LENGTH. 4.5 mm.
HEAD. Head slightly wider than long. Integument black, except part of mandibles dark reddish-brown. Face sparsely covered with long, greyish, erect hair (Fig. 19C). Clypeus almost flat with dispersed large, shallow punctation (i = 1–2 d); surface between punctures apically smooth or only superficially sculptured, shiny, basally more heavily sculptured and matt (Fig. 19 C–D). Malar area medially narrow, almost linear. Antenna dorsally blackish-brown, ventrally yellowish-brown.
MESOSOMA. Integument black. Mesoscutal disc between punctures strongly reticulate, matt; disc sparsely (i = 2–3 d), finely and shallowly punctate (Fig. 19B). Metanotum about half as long as basal area of propodeum, apically with distinct, narrow carinate depression (Fig. 19B). Propodeum with distinct carination covering more than half of the basal area (Fig. 19B). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with short, greyish, erect hair (Fig. 19A).
WINGS. Yellowish-brown; wing venation and stigma brown.
LEGS. Integument black to dark reddish-brown; fore tibia basally with small yellow spot. Vestiture greyish-white, scopa greyish-white, dorsally blackish-brown.
METASOMA. Integument black, apical margins of terga sometimes narrowly translucent dark reddishbrown (Fig. 19E). Discs of T1 and T2 without hair; following terga with sparse and short but increasingly more and longer hair; apical tergal hair bands missing on all terga (Fig. 19E). Prepygidial and pygidial fimbriae very sparse, brownish. Terga impunctate, superficially and ± densely sculptured, mostly shiny; T2–T4 with finely sculptured, narrow and indistinct apical tergal depression (Fig. 19E).
Male
BODY LENGTH. 4.4 mm.
HEAD. Head slightly wider than long. Integument black, except mandible partly dark reddish-brown. Face densely covered with long, greyish-white, erect hair. Malar area medially narrow, almost linear. Antenna dorsally dark brown, ventrally dark orange-brown (Fig. 20A).

LEGS. Integument black to dark reddish-brown; fore tibia anteriorly dominantly yellow to yellowishbrown (Fig. 20A). Hind tibia unmodified. Vestiture greyish-white.
METASOMA. Integument black, apical margins of terga partly translucent yellowish to dark reddishbrown (Fig. 20C). Disc of T1 without hair; apical tergal hair bands missing on all terga (Fig. 20C). Terga impunctate, sculptured and slightly matt; terga with broad and superficially sculptured, more shiny apical tergal depression (Fig. 20C). S3–S5 without distinct apical hair fringes.
