Treatment

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

( Figure 16 View Figure 16 )

Diagnosis. Vertical lobe of gonopod broad, large, strongly sclerotized, with one process apico-medially ( Figure 16C, D View Figure 16 ).

Description

Wing. Wing with ca 22–23 minute, peg-like spinules on ventral surface of costal vein between R 2+3 and R.

4+5

Leg. Hind femur with ca four or five long setae postero-ventrally; hind tibia with ca 10 setae submedio-ventrally.

Male terminalia. Epandrium entirely separated laterally at mid-dorsal portion, with ca 12– 14 setae near posterior to ventral margins ( Figure 16A View Figure 16 ). Surstylus pubescent on lateral margin, not expanded at postero-ventral corner, with ca six long prensisetae on distal margin, and a few thin setae on lateral to distal margin and inner surface. Anterior portion of hypandrium entirely thin ( Figure 16C View Figure 16 ). Parameres separated from each other, lobeshaped, each with apical, longer, strongly sclerotized and small, lateral, slightly sclerotized processes and ca six sensilla on subdistal mesal surface ( Figure 16D View Figure 16 ). Aedeagus separated into one pair of small rods, pointed both apically, medially each fused to base of paramere; outer membrane undeveloped ( Figure 16E View Figure 16 ). Ejaculatory apodeme: apical plate with ca four pits on each lateral margin; stalk thick, slightly curved ( Figure 16G View Figure 16 ).

Measurements. BL 53.26 mm in holotype (1 „ paratype: 3.00); ThL 51.38 mm (1.15); WL 52.51 mm (2.57); WW 51.18 mm (1.13).

HOLOTYPE: „, Yunnan: Mt Jizu , 17 August 2000, H.-W. Chen leg. ( KIZ).

PARATYPES: 3 „, Yunnan: Bamboo Temple , 31 July 2000, 15 July 2002, J.-J. Gao leg. ( KIZ, DBSU and SEHU) .

Distribution. China (Yunnan).

Relationship. This species somewhat resembles A. (A.) cuii in the shapes of paramere and aedeagus, but can be distinguished from it by the vertical lobe of gonopod with one large, much-sclerotized process apico-medially.

Etymology. In reference to the broad, large vertical lobe of gonopod.

Amiota (Amiota) luguhuensis Chen and Watabe , sp. nov.

( Figure 17 View Figure 17 )

Diagnosis. Vertical lobe of gonopod slightly sclerotized apically, height longer than width ( Figure 17C View Figure 17 ).

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 three long setae postero-ventrally; hind tibia with ca 10 setae ventrally.

Male terminalia. Epandrium entirely separated laterally at mid-dorsal portion, with ca eight setae near posterior to ventral margins ( Figure 17A View Figure 17 ). Surstylus glabrous on medial mesal surface, not expanded at postero-ventral corner, with five longer prensisetae on distal margin, and several thin setae on distal margin to inner surface. Anterior portion of hypandrium entirely thin ( Figure 17C View Figure 17 ). Parameres separated from each other, lobe-shaped, each with apical and lateral, strongly sclerotized, pointed processes and ca five sensilla on medial mesal surface ( Figure 17D View Figure 17 ). Aedeagus separated into one pair of small rods, each fused to base of paramere; outer membrane undeveloped ( Figure 17D, E View Figure 17 ). Ejaculatory apodeme: apical plate with ca five pits on each lateral margin; stalk thick, curved ( Figure 17F View Figure 17 ).

HOLOTYPE: „, Yunnan: Lake Lugu , 25 July 2001, L.-P. He leg. ( KIZ).

Distribution. China (Yunnan).

Relationship. This species resembles A. (A.) arcuata sp. nov. in the shape of paramere and aedeagus, but can be distinguished from it by the vertical lobe of gonopod height longer than width.

Etymology. In reference to the type locality.
