Figs 1–9, 86
DiagnosisNasus elongate, apex slightly expanded. Scape and pedicel of antenna yellow; flagellar segments 1–4 grayish yellow, other segments pale brown, except base darker. Prescutum almost wholly reddish brown with four olive-gray striped pruinescence, median stripe broadened apically and gradually narrowing to base. Posterior margin of gonocoxite with a sharp black spine. Tergite 9 separated medially, with a pair of angular arms arising from ventral surface of tergite 9, with granulated margins, apex with a small inner projection, outer surface of arms with a pair of depressions (Fig. 9). Outer gonostylus slender, spoon-like. Lower beak of inner gonostylus absent.
EtymologyThe species is named after the shape of inner gonostylus, it looks like a ‘Magatama’, a curved commashaped bead from prehistoric Japan, called ‘勾玉’ in China. The name is to be treated as a noun in apposition.
