Treatment

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

( Figure 3 View Figure 3 )

Diagnosis. Paramere slender; distal part longer than basal one, apically slightly broadened in lateral view, with ca five or six minute sensilla on distal margin ( Figure 3D View Figure 3 ).

Description

Thorax. Thorax yellow, with dull, brown patches and stripes; scutellum yellow, brown on margin; pleura 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 to third yellow medially.

Male terminalia. Epandrium with ca 12 setae near posterior margin and at postero-ventral corner ( Figure 3A View Figure 3 ). Surstylus with ca eight prensisetae ( Figure 3B View Figure 3 ). Paramere acutely curved basally and formed triangular corner in lateral view, with ca 15–16 sensilla submedially and subapically ( Figure 3D View Figure 3 ). Aedeagal apodeme less-sclerotized ( Figure 3C, D View Figure 3 ). Ejaculatory apodeme with ca five pits on each lateral margin; stalk as long as the apical plate ( Figure 3E View Figure 3 ).

Measurements. BL 52.55 mm in holotype (range in 3 „ paratypes: 2.48–2.65); ThL51.00 mm (1.00–1.15); WL52.00 mm (1.90–2.00), WW 50.96 mm (0.88–0.90).

HOLOTYPE: „, Yunnan: Yexianggu , 13 September 2002, ex tree trunks, H.-W. Chen leg. ( KIZ).

PARATYPES: 4 „, Yunnan: same data as the holotype ( KIZ, DBSU and SEHU) .

Distribution. China (Yunnan).

Relationship. This species resembles A. (A.) sinuata in the general morphology of male terminalia, but can be distinguished from the latter by the apically broadened paramere (not broadened in sinuata ).

Etymology. In reference to the type locality.
