Differential diagnosis
The new species most resembles S. brachyurum sp. nov. and S. pyrrhonae , but it is distinguished from them by the long malar space, 1.3–1.4 times as long as the basal mandibular width (0.9–1.2 times in S. brachyurum and S. pyrrhonae ), and the yellowish white marking on the apex of the metasoma (entirely black in S. brachyurum and S. pyrrhonae ).
Description
Female (n = 11)
BODY LENGTH. 7.5–10.0 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. 2a View Fig ). Clypeus 0.5–0.7 times as long as wide, with three weak projections of equal size ( Figs 2a View Fig , 3a View Fig ). Face 0.7–0.8 times as long as wide. Length of malar space 1.3–1.4 times as long as basal mandibular width. Ocello-ocular line/lateral ocellar diameter
= 1.1–1.3. Postocellar line/lateral ocellar diameter = 0.7–1.0. Antenna with 30–31 flagellomeres; first flagellomere 1.3–1.5 times as long as second flagellomere.
MESOSOMA. Propleuron densely punctate ( Fig. 5a View Fig ). Lateral area of pronotum weakly punctate and transversely striate medially. Collar sparsely punctate. Mesoscutum densely punctate ( Fig. 5a View Fig ). Subalar prominence densely punctate ( Fig. 5a View Fig ). Scutellum weakly punctate in dorsal view. Postscutellum flattened in lateral view ( Fig. 5a View Fig ). Metapleuron strongly punctate ( Fig. 5a View Fig ). Propodeum indistinctly carinate ( Fig. 6a View Fig ). Area superomedia confluent with area petiolaris. Fore wing length 6.5–9.0 mm. Vein cu-a basal to vein Rs&M ( Fig. 4a View Fig ). Vein rs-m opposite or basal to vein 2m-cu ( Fig. 4a View Fig ). Hind femur 3.2–3.5 times as long as maximum depth in lateral view, without distinct convexity ventrally. Hind tibia 10.0–11.7 times as long as maximum depth in lateral view. First hind tarsomere 2.1–2.6 times as long as second and 1.9–2.2 times as long as longer hind tibial spur.
METASOMA. T1 1.9–2.2 times as long as maximum width, 1.9–2.2 times as long as T2. T2 0.7 times as long as maximum width. T1 sparsely punctate. T2–T8 densely punctate. S1 without distinct sharp projection basally. Ovipositor sheath 2.1–2.5 times as long as hind tibia.
COLOR. Body black ( Fig. 1a View Fig ). Antennal flagellum with a white band ( Fig. 1a View Fig ). Inner margin of eye yellowish white, pale color sometimes extended to most of face ( Fig. 2a View Fig ). Clypeus, basal area of mandible, scutellum, postscutellum, propodeum, apices of metasomal tergites, apex of metasoma, and subgenital plate yellowish white (propodeum and T1 sometimes entirely black). Fore and mid legs yellowish brown ( Fig. 1a View Fig ). Fore wing with a rounded apical dark mark ( Fig. 4a View Fig ).
Male (n = 12; genitalia, n = 2)
Similar to female ( Fig. 1b View Fig ). Body length 6.0–10.0 mm. Head 0.6–0.7 times as long as wide in dorsal view. Vertex 0.4–0.5 times as long as maximum length of eye in dorsal view. Ocello-ocular line/ lateral ocellar diameter = 1.0–1.4. Postocellar line/lateral ocellar diameter = 0.8–1.2. Antenna with 31–35 flagellomeres. Hind femur 3.4–3.6 times as long as maximum depth in lateral view. Hind tibia 10.0–11.7 times as long as maximum depth in lateral view. First hind tarsomere 1.9–2.2 times as long as longer hind tibial spur. T1 2.0–2.5 times as long as maximum width, 1.8–2.1 times as long as T2. T2 0.7–0.8 times as long as maximum width.
