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.
