Diagnosis

The female of S. minutuloides sp. nov. can be separated from other species of this group by the combination of the following characters: head distinctly broader than long, supraclypeal area and clypeus densely and distinctly punctate, only partly superficially sculptured and matt ( Fig. 14 C–D), scutum densely but relatively finely punctate ( Fig. 14 E–F), stigma brown, apical margins of metasomal terga black, terga densely and coarsely punctate ( Fig. 14B ). The male is unknown.

Etymology

Named for the small body size of the species.

Description

Female

BODY LENGTH. 4.7 mm.

HEAD. Head wider than long. Integument black, except part of mandibles dark reddish-brown. Face sparsely covered with long, greyish-brown, erect hair ( Fig. 14C ). Clypeus strongly convex with coarse and dense punctation (i = 1.0–1.5 d); surface between punctures mostly smooth and shiny, basally partly superficially sculptured and less shiny ( Fig. 14 C–D). Malar area medially narrow, almost linear. Antenna dorsally blackish-brown, ventrally yellowish-brown ( Fig. 14C ).

MESOSOMA. Integument black. Mesoscutal disc between punctures superficially reticulate, slightly matt; disc sparsely (i = 3–5 d) and finely punctate ( Fig. 14 E–F). Metanotum slightly shorter than basal area of propodeum, apically with indistinct, narrow carinate depression ( Fig. 14F ). Propodeum basally finely but broadly carinate ( Fig. 14F ). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with short, greyish, erect hair ( Fig. 14A ).

WINGS. Brownish; wing venation and stigma brown.

LEGS. Integument black. Vestiture greyish-white, scopa greyish-white, dorsally blackish-brown.

METASOMA. Integument black, apical margins of terga partly narrowly translucent dark reddish-brown ( Fig. 14B ). Discs of T1 and T2 without hair, following terga with very short but increasingly more and longer hair; apical tergal hair bands missing on all terga ( Fig. 14B ). Prepygidial and pygidial fimbriae blackish-brown. T1 densely (i = 1 d) but very finely punctate, between punctures polished and shiny; T2–T4 basally superficially sculptured, apically smooth and shiny, with dense (i = 0.5–1.0 d), fine, superficial punctation; T2–T4 with superficially sculptured, broad apical tergal depression ( Fig. 14B ).
