Treatment

Amiota (Amiota) subsinuata Chen and Aotsuka View in CoL , sp. nov.

( Figure 2 View Figure 2 )

Diagnosis. Vertical lobe of gonopod extremely elongated basally, forming one pair of strongly curved, rod-shaped processes with one sickle-like projection submedially ( Figure 2C, D View Figure 2 ).

Description

Thorax. Thorax dark yellow, medially with one broadened, brown stripe, and laterally with two thin versicolour stripes; pleura yellow, with brown patch on upper half; scutellum dark yellow, with brown margin.

Wing. Ventral surface of costal vein with ca 14–15 distinct, peg-like spinules between R 2+3 and R 4+5.

Abdominal tergites. Abdominal tergites dark brown; second yellow medially; third and fourth with yellow stripe medially; fifth and sixth entirely black.

Male terminalia. Epandrium with ca 10–11 setae near posterior margin and at postero-ventral corner ( Figure 2A View Figure 2 ). Surstylus with ca seven prensisetae ( Figure 2B View Figure 2 ). Hypandrial apodeme with two pairs of sharply pointed projections subbasally and distally. Paramere basally curved triangularly in lateral view, with a row of ca eight or nine sensilla submedially to apically. Aedeagal apodeme very small, less sclerotized ( Figure 2C, D View Figure 2 ). Ejaculatory apodeme with ca six pits on each lateral margin; stalk slightly longer than the apical plate ( Figure 2E View Figure 2 ).

Measurements. BL 53.03 mm; ThL 51.40 mm; WL 52.47 mm; WW51.00 mm.

HOLOTYPE: „, Yunnan: Yexianggu , 14 September 2002, H.-W. Chen leg. ( KIZ).

Distribution. China (Yunnan).

Relationship. This species closely resembles A. (A.) sinuata in the general morphology of male terminalia, but can be distinguished from it by the vertical lobe of gonopod being elongated basally (not elongated basally in sinuata ).

Etymology. In reference to a close relationship to sinuata .
