Differential diagnosis
This new species most resembles S. pseudonigrum sp. nov., but is easily distinguished from it by the distinct apical marking on the fore wing (the apical portion is only infuscate in S. pseudonigrum sp. nov.).
Description
Female (n = 41)
BODY LENGTH. 10.0–12.0 mm.
HEAD. Vertex 0.4–0.5 times as long as maximum length of eye in dorsal view. Frons without a depression between eye and antennal socket in frontal view ( Fig. 2f View Fig ). Clypeus 0.5–0.6 times as long as wide, with three weak projections of equal size ( Fig. 2f View Fig ). Face 0.6–0.7 times as long as wide. Length of malar space 1.1–1.2 times as long as basal mandibular width. Ocello-ocular line/lateral ocellar diameter = 1.1–1.7. Postocellar line/lateral ocellar diameter = 1.0–1.3. Antenna with 28–30 flagellomeres; first flagellomere 1.3–1.4 times as long as second flagellomere.
MESOSOMA. Propleuron densely punctate ( Fig. 5f View Fig ). Lateral area of pronotum densely punctate and transversely striate medially. Collar weakly punctate. Mesoscutum densely punctate ( Fig. 5f View Fig ). Subalar prominence extensively punctate ( Fig. 5f View Fig ). Scutellum densely punctate in dorsal view. Postscutellum flattened in lateral view ( Fig. 5f View Fig ). Metapleuron strongly punctate ( Fig. 5f View Fig ). Propodeum strongly carinate ( Fig. 6f View Fig ). Area externa and area dentipara sparsely punctate ( Fig. 6f View Fig ). Area basalis and area superomedia polished ( Fig. 6f View Fig ). Area posteroexterna confluent with area petiolaris and polished ( Fig. 6f View Fig ). Fore wing length 6.0– 8.5 mm. Vein cu-a basad of vein Rs&M ( Fig. 4f View Fig ). Vein rs-m opposite or distad of vein 2m-cu ( Fig. 4f View Fig ). Hind femur 3.4–3.6 times as long as maximum depth in lateral view, without distinct convexity ventrally. Hind tibia 9.4–11.3 times as long as maximum depth in lateral view. First hind tarsomere 2.4–2.8 times as long as second and 2.2–2.5 times as long as longer hind tibial spur.
METASOMA. T1 2.0–2.3 times as long as maximum width, 2.4–2.6 times as long as T2. T2 0.6 times as long as maximum width. T1 weakly and sparsely punctate. T2–T8 weakly and densely punctate. S1 without distinct sharp projection basally. Ovipositor sheath 2.1–2.3 times as long as hind tibia.
COLOR. Body black ( Fig. 1e View Fig ). Antennal flagellum with a white band ( Fig. 1e View Fig ). Inner margin of eye and middle area of mandible yellowish white ( Fig. 2f View Fig ). Fore and mid legs grayish brown ( Fig. 1e View Fig ). Apex of hind tarsus sometimes yellowish white ( Fig. 1e View Fig ). Fore wing with an apical dark mark, extending downwards ( Fig. 4f View Fig ).
Male (n = 1).
Similar to female ( Fig. 1f View Fig ). Body length: 9.0 mm. Head 0.7 times as long as wide in dorsal view. Face 0.8 times as long as wide. Antenna with 36 flagellomeres; first flagellomere 1.1 times as long as second flagellomere. Fore wing length 8.0 mm. Hind femur 3.2 times as long as maximum depth in lateral view. First hind tarsomere 3.7 times as long as longer hind tibial spur. T1 2.5 times as long as maximum width, 2.3 times as long as T2. T2 1.0 times as long as maximum width. Antennal flagellum without a white band ( Fig. 1f View Fig ). Face, clypeus, basal area of mandible, apices of T1–3, and fore and middle legs yellowish white.
Male genitalia of this species were not examined due to the limited number of specimens.
