Treatment

Amiota (Amiota) shangrila Chen and Watabe View in CoL , sp. nov.

( Figure 20 View Figure 20 )

Diagnosis. Vertical lobe of gonopod heavily sclerotized apically, basal two-thirds squareshaped ( Figure 20D View Figure 20 ); lateral process of paramere slender ( Figure 20C View Figure 20 ).

Description

Wing. Wing with ca 21–22 minute, peg-like spinules on ventral surface of costal vein between R 2+3 and R 4+5.

Leg. Hind femur with six long setae postero-ventrally; hind tibia with five setae ventrally. Male terminalia. Epandrium nearly separated laterally at mid-dorsal portion, with ca 18–20 setae near posterior to ventral margins ( Figure 20A View Figure 20 ). Surstylus glabrous on medial mesal surface, not expanded at postero-ventral corner, with six longer prensisetae on distal margin, and several thin setae on outer to inner surface ( Figure 20B View Figure 20 ). Anterior portion of hypandrium very thin ( Figure 20C View Figure 20 ). Parameres separated from each other, lobe-shaped, with ca three apically, much-sclerotized sensilla on medial surface ( Figure 20D View Figure 20 ). Aedeagus separated into one pair of small rods, each fused to base of paramere; outer membrane undeveloped ( Figure 20E View Figure 20 ). Ejaculatory apodeme: apical plate with ca four or five pits on each lateral margin; stalk thick, long ( Figure 20F View Figure 20 ).

Measurements. BL 53.39 mm in holotype; ThL 51.38 mm; WL 52.83 mm; WW 51.24 mm.

HOLOTYPE: „, Yunnan: Lake Lugu , 23 July 2001, J.-J. Gao leg. ( KIZ).

Distribution. China (Yunnan).

Relationship. This species resembles A. (A.) ailaoshanensis sp. nov. in the general morphology of male genitalia, especially paramere and aedeagus, but can be distinguished from it by the vertical lobe of gonopod basal two-thirds quadrate (roundish in ailaoshanensis ).

Etymology. In reference to the type locality.
