AMIOTA REIKAE XU & CHEN SP. NOV. ( FIG. 1 )

Specimens examined: Holotype male ( SCAU 121071 ) and five male paratypes ( SCAU 121072–121076 ), China, Mengla, Xishuangbanna , Yunnan, 600 m a.s.l., 17, 18 April 2007, HW Chen and JJ Gao.

Etymology: Patronym, in honor of Ms Lihua Wang (SCAU), who helped Hongwei Chen in the study of drosophlids.

Diagnosis: This species is similar to A. apodemata in the male terminalia, can be distinguished from the latter by having the paramere broad, slightly bifurcated dorsad, with a strongly sclerotized, arcuate process basally (pr; Fig. 1C, D ).

Description: Only the important characters are listed here; see Chen & Toda (1998a) for the rest (common to the apodemata group). Male terminalia: epandrium not constricted mid-dorsally, with about nine setae near posterior to ventral margins on each side of the body ( Fig. 1A ). Surstylus lacking pubescence, with finger-like process at posteroventral corner, about seven prensisetae on distal margin, and a few stout, spine-like setae on inner surface ( Fig. 1B ). Hypandrium narrowly separated into two lateral arches at middle of anterior portion ( Fig. 1C, D ). Gonopods sclerotized and slender ( Fig. 1D ). Parameres subbasally fused to each other, with numerous pits along outer margins ( Fig. 1C, D ). Aedeagus single, somewhat sclerotized, spoon-shaped lobe, basally fused to apodeme ( Fig. 1C, D ). Aedeagal apodeme nearly straight ( Fig. 1C, D ). Female: unknown.
