Differential diagnosis
This species resembles S. brachyurum sp. nov. and S. nigrum sp. nov.; however, it can be distinguished from them by the rounded apical dark mark on the fore wing (extending downwards in S. brachyurum sp. nov. and S. nigrum sp. nov.), and turned up clypeus in lateral view (not turned up in S. brachyurum sp. nov. and S. nigrum sp. nov.). It is also easily distinguished from other Japanese Spilopteron by the above character states.
Description
Female (n = 11)
BODY LENGTH. 10.5–13.0 mm.
HEAD. Vertex 0.6–0.7 times as long as maximum length of eye in dorsal view. Frons without a depression between eye and antennal socket in frontal view ( Fig. 2i View Fig ). Clypeus 0.6 times as long as wide, with two strong lateral projections, and anterior margin turned up ( Figs 2i View Fig , 3i View Fig ). Face 0.6–0.7 times as long as wide. Length of malar space 0.9–1.2 times as long as basal mandibular width. Ocello-ocular line/lateral ocellar diameter = 1.4–1.8. Postocellar line/lateral ocellar diameter = 0.9–1.4. Antenna with 32–33 flagellomeres; first flagellomere 1.3 times as long as second flagellomere.
MESOSOMA. Propleuron densely punctate ( Fig. 5i View Fig ). Lateral area of pronotum densely punctate and transversely striate medially ( Fig. 5i View Fig ). Collar weakly punctate. Mesoscutum densely punctate. Subalar prominence extensively punctate ( Fig. 5i View Fig ). Scutellum weakly punctate in dorsal view. Postscutellum flattened in lateral view ( Fig. 5i View Fig ). Metapleuron weakly punctate ( Fig. 5i View Fig ). Propodeum strongly carinate ( Fig. 6i View Fig ). Area externa and area dentipara punctate ( Fig. 6i View Fig ). Area basalis polished ( Fig. 6i View Fig ). Area superomedia weakly carinate ( Fig. 6i View Fig ). Area petiolaris polished ( Fig. 6i View Fig ). Fore wing length 9.5–10.0 mm. Vein cu-a basad of vein Rs&M ( Fig. 4i View Fig ). Vein rs-m opposite vein 2m-cu ( Fig. 4i View Fig ). Hind femur 3.5–3.9 times as long as maximum depth in lateral view, without distinct convexity ventrally. Hind tibia 10.8– 11.8 times as long as maximum depth in lateral view. First hind tarsomere 2.4–2.6 times as long as second and 2.2–2.5 times as long as longer hind tibial spur.
METASOMA. T1 2.2–2.5 times as long as maximum width, 2.0–2.3 times as long as T2. T2 0.6–0.7 times as long as maximum width. T1 weakly and sparsely punctate. T2–T8 weakly densely punctate. S1 without distinct sharp projection basally. Ovipositor sheath 2.0–2.1 times as long as hind tibia.
COLOR. Body black ( Fig. 5i View Fig ). Antennal flagellum with a white band. Inner margin of eye and hind tarsomeres 3–5 white to yellowish white. Fore and mid legs brown. Fore wing with a rounded apical dark mark ( Fig. 4i View Fig ).
Male (n = 7; genitalia, n = 2)
Similar to female. Clypeus 0.6–0.8 times as long as wide. Length of malar space 1.0–1.3 times as long as basal mandibular width. Ocello-ocular line/lateral ocellar diameter = 1.4–2.0. Postocellar line/lateral ocellar diameter = 1.1–1.5. Antenna with 37–39 flagellomeres; first flagellomere 1.2–1.3 times as long as second flagellomere. Hind femur 3.4–4.1 times as long as maximum depth in lateral view. First hind tarsomere 2.1–2.7 times as long as second and 2.7–3.3 times as long as longer hind tibial spur. Metasoma. T1 2.6–3.0 times as long as maximum width, 1.9–2.3 times as long as T2. T2 0.8–1.0 times as long as maximum width. Face, basal area of mandible, hind tarsus and apices of T1 and T2 yellowish white. Fore and mid legs, trochanters and trochantelli yellowish brown.
Subgenital plate pentagonal with basal angle obtuse ( Fig. 8h View Fig ), its length ca 0.7 times as long as aedeagus. Paramere short, basal part strongly projecting towards base of subgenital plate ( Fig. 7o View Fig ). Aedeagus gently curved, its penis valve ca 1.3 times as long as basal apodeme ( Fig. 8h View Fig ).
Distribution
