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.
