AMIOTA HESONGENSIS XU & CHEN SP. NOV. ( FIG. 3 )

Specimens examined: Holotype male ( SCAU 110042 ) and four male paratypes ( SCAU 121256–121259 ), China, Hesong, Menghai, Xishuangbanna , Yunnan, 1900 m a.s.l, 6–9 April 2011, J.M. Lu, Z.F. Shao, Y.R. Su, and S.J. Yan.

Etymology: Pertaining to the type locality.

Diagnosis: This species is similar to A. sinuata in the shape of the distal part of the paramere, but can be distinguished by the following characters. In A. sinuata , the distal part of the paramere is slightly longer than the basal part, which is basally not narrowed in lateral view ( Fig. 1C in Chen & Toda, 1998b).

Description: Male. Thorax brownish yellow, with dark-brown patches and stripes; pleura brownish; scutellum yellow, brown on margin. Abdominal tergites black; first to third yellow, medially. Male terminalia: epandrium pubescent except for anterior margin, with about ten setae near posterior margin on each side of the body ( Fig. 3A ). Surstylus with several setae and about nine prensisetae ( Fig. 3B ). Vertical lobe of gonopod broad, arched, slightly sclerotized ( Fig. 3C ). Paramere with a row of ~12 sensilla submedially to apically ( Fig. 3C ). Aedeagal apodeme longer than wide ( Fig. 3C ). Female: unknown.
