Scaphotettix Matsumura 1914

Scaphotettix Matsumura, 2014 Scaphotettix Matsumura, 1914: 227; Zahniser & Dietrich, 2013: 118. Type species: Scaphotettix viridis Matsumura, 1914. Diagnosis. Body dorsoventrally flattened. Head slightly narrower to slightly wider than pronotum; crown longer medially than length next to eye; ocelli on anterior margin of crown, close to eye; face angularly convex dorsally in profile; anteclypeus narrowing towards apex; antennae arising near upper corners of eye. Forewing with outer subapical cell extended to wing margin. Male genitalia. Pygofer lobe elongate, with one or two elongate processes at mid-ventral margin, extending caudally, rarely curved medially (S. aurantiacus), dorsal margin rarely with a short internal process on each side (S. aurantiacus). Subgential plate long-triangular with uniseriate row of macrosetae on lateral margin. Style elongate and linear, with margin between inner and outer basal arms strongly oblique; preapical lobe undeveloped; apical process tapered to acute or rounded apex, short and curved laterally, rarely elongate and curved medially (S. aurantiacus). Connective with arms broadly arched, stem reduced, connective rarely trapezoidal (S. aurantiacus). Aedeagal shaft simple, curved dorsally with or without processes; gonopore apical on ventral surface; rarely with distinct basal apodeme and preatrium present (S. aurantiacus). Distribution. Oriental and Pacific region. Remarks. Scaphotettix was revised by Dai et al. (2009) who adequately described the genus; all previously described species except the type species were removed from the genus and three species were described as new. Subsequently, Zahniser & Dietrich (2013) transferred the genus from Athysanini to Mukariini. Checklist to species of Scaphotettix Matsumura, 2014 aurantiacus sp. nov.
