Diagnosis.
This species resembles
S. toyaensis
Okada & Sidorenko,
1992
in some characters of the male terminalia, but can be distinguished by the mesonotum dark brown, with 1 thin, unconspicuous, yellow longitudinal stripe medially, yellowish brown laterally (
Fig. 2C
); aedeagus slightly flat apically in ventral view (
Fig. 6C, D
). The minimum interspecific genetic distance to
S. toyaensis
is 3.5%, which is smaller than to other species (
Table 2
).
Description.
Male: Frons black. First flagellomere yellow on basal 2/3, black on distal 1/3. Clypeus and palpus yellow. Katepisternum entirely white. Scutellum black (
Fig. 2C
). Femur of foreleg with 4 long erect setae near distal part of posteroventral surface. Abdominal tergites dark brown to black (
Fig. 2C
). Male terminalia (
Fig. 6
): Epandrium slightly protruded ventrally, with numerous setae on posterior portion per side. Surstylus with numerous setulae basally. Cercus lacking pubescence. Tenth sternite broadened, with 1 pair of processes submedially. Paramere with 1 setula.
