Treatment

Amiota (Amiota) curvispina Chen and Gao View in CoL , sp. nov.

( Figure 5 View Figure 5 )

Diagnosis. Paramere and aedeagus much sclerotized, basally fused to each other, apically pointed ( Figure 5D, E View Figure 5 ); paramere lacking sensillum ( Figure 5D, E View Figure 5 ); M-shaped processes of gonopod long, apically much sclerotized and sharply pointed ( Figure 5C View Figure 5 ).

Description

Wing. Wing with ca 18–21 minute, peg-like spinules on ventral surface of costal vein between R 2+3 and R 4+5.

Male terminalia. Epandrium constricted heavily, with ca 12 setae from posterior to ventral margins ( Figure 5A View Figure 5 ). Surstylus pubescent medially, with three aristate processes fused to each other and forming palm-like lobe on mesal surface, finger-like process at postero-ventral corner, ca 14–15 long prensisetae on distal margin, and a few spine-like stout setae on inner surface ( Figure 5B View Figure 5 ). Anterior portion of hypandrium slightly

broadened at middle ( Figure 5C View Figure 5 ). Ejaculatory apodeme: apical plate with ca 11 pits on each lateral margin, stalk thin, expanded on base ( Figure 5F View Figure 5 ).

Measurements. BL 52.96 mm in holotype; ThL 51.25 mm; WL 52.43 mm; WW 51.13 mm.

HOLOTYPE: „, Yunnan: Mt Wuliang , 1 July 2001, J.-J. Gao leg. ( KIZ).

Distribution. China (Yunnan).

Relationship. This species closely resembles A. (A.) flagellata in having the muchsclerotized paramere and aedeagus, but can be distinguished from the latter by the hind tarsus lacking long setae (with long, fringe-like setae in flagellata ).

Etymology. Referring to the curved aedeagus.

Amiota (Amiota) lipingae Chen and Gao , sp. nov.

( Figure 6 View Figure 6 )

Diagnosis. Paramere much sclerotized, basally curved in lateral view; aedeagus slender, curved, slightly sclerotized ( Figure 6D, E View Figure 6 ).

Description

Wing. Wing with ca 18–21 minute, peg-like spinules on ventral surface of costal vein between R 2+3 and R 4+5.

Male terminalia. Epandrium constricted heavily, with ca 16 setae from posterior to ventral margins ( Figure 6A View Figure 6 ). Surstylus lacking pubescence, with four aristate processes basally and forming palm-like lobe on mesal surface, finger-like process at postero-ventral corner, eight long prensisetae on distal margin, and a few spine-like stout setae on inner surface ( Figure 6B View Figure 6 ). Anterior portion of hypandrium slightly broadened at middle ( Figure 6C View Figure 6 ). Vertical lobe of gonopod with two sclerotized basally fused M-shaped processes. Paramere submedially with ca three or four sensilla basally articulated with aedeagus ( Figure 6D View Figure 6 ). Aedeagus separated into two processes as long as paramere, slightly sclerotized, somewhat expanded subbasally ( Figure 6E View Figure 6 ); outer membrane high and erected basally. Ejaculatory apodeme: apical plate with ca nine pits on each lateral margin; stalk thick ( Figure 6F View Figure 6 ).

Measurements. BL 53.23 mm; ThL 51.70 mm; WL 52.90 mm; WW 51.70 mm.

HOLOTYPE: „, Yunnan: Lake Lugu , 23 July 2001, L.-P. He leg. ( KIZ).

Distribution. China (Yunnan). Relationship. This species is similar to A. (A.) aristata in the shape of aedeagus, but can be easily distinguished from it by the basally curved paramere (straight in aristata ).

Etymology. Patronym of the collector Ms L.-P. He.
