Female – Length: 1.2 mm. Black, A1-A6 reddish yellow; legs dark brown; trochanters, fore tibia, both ends of mid tibia, base of hind tibia, and segments 1–4 of all tarsi reddish yellow. Head from above (Fig. 41) 1.7 times as wide as long, very slightly wider than mesosoma, evenly and distinctly reticulate-coriaceous; occiput with a complete but not strong carina. OOL equal to diameter of lateral ocellus. Head in frontal view 1.1 times as wide as high; antenna (Fig. 42) with A1 0.8 times as long as height of head. Mesosoma 1.5 times as long as wide, 1.1 times as high as wide. Sides of pronotum distinctly reticulate-coriaceous as head, smooth only in extreme lower corner. Mesoscutum sparsely hairy, uniformly and somewhat finer reticulate-coriaceous than head; notauli posteriorly hardly indicated; mid lobe posteriorly slightly prolonged, rather finely pointed, not smooth or swollen, with about seven long hairs at each side. Mesopleuron smooth. Scutellum (Fig. 43) finely sculptured and hairy, with a strong, slightly semitransparent spine, without lamella below. Metapleuron with pilosity all over. Propodeal carinae low and straight. Fore wing hardly shorter than body, 2.5 times as long as wide, faintly brownish, with fine and dense microtrichia, without marginal cilia. Marginal cilia of hind wing 0.2 width of wing. Metasoma (Fig. 44) 0.9 times as long as mesosoma, hardly as wide as this, 1.4 times as wide as high. Hind margins of T2–T6 distinctly reticulate-coriaceous; T4–T5 each with a transverse row of punctures with hairs.

Differs from S. acutispinus BUHL, 1998 in structure of head, from S. hansseni BUHL, 1998 e.g. in absence of notauli and sculpture of mesopleuron, from S. marttii BUHL, 2004 in shape of scutellum, and from S. romsoeensis BUHL, 1999 e.g. in slightly different structured head and antennae, and in lacking marginal cilia of fore wing, cf. also BUHL (1998 a, b, 1999, 2004 a).
