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

( Figure 18 )

Diagnosis. Vertical lobe of gonopod broadened, large, with three pointed processes; medial process slender, less sclerotized; lateral ones much sclerotized ( Figure 18C ); paramere apically with one pointed, sclerotized process and submedially with one bifurcated process ( Figure 18D ).

Description

Wing. Wing with 22–23 minute, peg-like spinules on ventral surface of costal vein between R and R 4+5.

2+3

Leg. Hind femur with ca four to six long setae postero-ventrally; hind tibia with a row of ca four to six setae ventrally.

Male terminalia. Epandrium entirely separated laterally at mid-dorsal portion, with 14–16 setae near posterior to ventral margins ( Figure 18A ). Surstylus pubescent on lateral margin, not expanded at postero-ventral corner, with six long prensisetae on distal margin and a few thin setae on lateral and ventral margins. Anterior portion of hypandrium entirely thin ( Figure 18C ). Parameres separated from each other, lobe-shaped, each with apical, longer, strongly sclerotized and small, lateral, slightly sclerotized processes and six sensilla on subdistal mesal surface ( Figure 18D ). Aedeagus separated into one pair of small rods, pointed apically, medially each fused to base of paramere; outer membrane undeveloped ( Figure 18E, F ). Ejaculatory apodeme: apical plate with four pits on each lateral margin; stalk thick, long ( Figure 18G ).

Measurements. BL 52.82 mm in holotype (5 „ paratypes: 2.63–2.97); ThL 51.20 mm (1.17–1.23); WL 52.25 mm (2.15–2.38); WW51.00 mm (0.93–1.00).

HOLOTYPE: „, Hunan: Mt Badagong , 3 August 2000, M. Nozawa leg. ( KIZ). PARATYPES: 9 „, same data as the holotype except for 1–7 August 2000, M. Nozawa, Y.-G. Hu and H. Takamori leg. ( KIZ, BDNU and SEHU).

Distribution. China (Hunan).

Relationship. This species somewhat resembles A. (A.) jizushanensis sp. nov. in the shape of male genitalia, but can be distinguished from it by the vertical lobe of gonopod with three processes.

Etymology. Patronym of the collector Mr M. Nozawa.
