Emended diagnosis.
Male: Vertex broad and flattened, slightly inclined. Occiput slightly convex. Frons inclined dorsally and ventrally, and nearly two times wider than antennal scape. Antennal scape shield-like. Median ocellus ovoid, lateral ocelli transversely ovoid. Two lateral ocelli located on the upper edge of the antennal scape and distributed in an inverted triangle with the median ocellus. Eyes ovoid. Pronotum broad and flattened. The median groove of the pronotal disc distinct. Posterior margin straight, the middle of the anterior margin concave, and the posterior and anterior margins almost equal in width. In the dorsal field of tegmina, bearing three chord veins, with the apical one connecting to the proximal part of the mirror by two veins; diagonal vein proximally bifurcated, both branches connecting to CuA vein; two oblique veins; mirror shield-like; dividing vein absent. Outer tympanum shaped as an elongate oval, inner tympanum ovoid or absent. Hind tibiae armed with dorsal spurs which almost equal in length. Epiphallus armed with a finger-like median lobe (Fig. 4 View Figure 4 ). Female: Similar to male in the head, pronotum, and feet features. Tegmina don’t reach the end of the abdomen, with longitudinal veins interspersed with false veins. Ovipositor smooth, arrow-like.
Included species.
Mitius blennus (Saussure, 1877) Mitius castaneus (Chapord, 1937), Mitius enatus (Gorochov, 1994), Mitius flavipes (Chopard, 1928), Mitius minor (Shiraki, 1911), Mitius minutulus Yang & Yang, 1995, Mitius vaturu (Otte & Cowper, 2007), and Stephoblemmus humbertiellus Saussure, 1877.
Remarks.
Stephoblemmus was established by Saussure (1877) and its dominant feature is the flat frons of males (Fig. S5C-D, G-H). Mitius was established by Gorochov (1985) and species of the genus possess two types of frons (truncated and rounded) (Fig. S5A-B, E-F, I-P). The phylogenetic relationship reveals that Stephoblemmus ( S. humbertiellus ) and Mitius ( M. minor (= S. minor comb. n. )) are sister group (Fig. 2 View Figure 2 ) and their male genitalia are also similar. Accordingly, Mitius should be a junior synonym of Stephoblemmus and we combine them.
