Treatment

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

( Figure 1 View Figure 1 )

Diagnosis. Prescutellar setae present; vertical lobe of gonopod apically with one pair of elongated processes, which is much sclerotized apically and contiguous to well-developed outer membrane of aedeagus with fine serration ( Figure 1D View Figure 1 ).

Description

Thorax. Thorax and scutellum dark yellow; pleura nearly brown.

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 black; first and second tergites yellow medially.

Male terminalia. Epandrium with ca 12–13 setae near posterior margin and at posteroventral corner ( Figure 1A View Figure 1 ). Surstylus with ca eight or nine prensisetae ( Figure 1B View Figure 1 ). Paramere slightly curved basally in lateral view, medially with ca 14–15 sensilla, distally with ca four or five minute sensilla. Aedeagal apodeme large, broadened, sclerotized ( Figure 1C, D View Figure 1 ). Ejaculatory apodeme with ca six pits on each lateral margin; stalk ca 2.2 times as long as the apical plate ( Figure 1E View Figure 1 ).

Measurements. BL 52.93 mm; ThL 51.40 mm; WL 52.50 mm; WW 51.25 mm.

HOLOTYPE: „, Yunnan: Wangtianshu , 11 September 2002, ex tree trunks, H.-W. Chen leg. ( KIZ).

Distribution. China (Yunnan).

Relationship. This species is very characteristic in having prescutellar setae, although it surely belongs to the sinuata species-group by other diagnostic characters (body colour, length of aristal branches, broad hypandrium, shaped of paramere, etc.). This suggests a taxonomic relationship between sinuata and apodemata groups.

Etymology. Referring to the outer membrane of aedeagus with fine serration.
