Amiota (Amiota) nuerhachii View in CoL sp. nov.

(figure 11)

Diagnosis. Paramere with ap-like expansion between apical and lateral processes figure 11D). Description. Male: Ocellar triangle and frontal vitta dark brown; fronto-orbital plate brownish orange in upper part, dark brown in lower part.

Fig. 11. Amiota (Amiota) nuerhachii sp. nov., holotype: (A) epandrium and cercus; (B) surstylus and tenth sternite; (C) hypandrium and gonopo d (ventral view); (D) parameres, aedeagus and aedeagal apodeme (ventral view); (E) aedeagal apodeme (lateral view); (F) ejaculatory apodeme (scale-line =0.1 mm).

Wing with 21–22 minute, peg-like spinules on ventral surface of costal vein between R and R.

2+3 4 +5

Legs: Mid tarsus with a row of minute cuneiform setulae on posteroventral surface. Hind femur with seven to eight long setae posteroventrally; hind tibia with seven setae ventrally.

Sixth abdominal tergite tapering laterally, but reaching lateral margin of fi fth tergite, broadened dorsally.

M ale terminalia: Epandrium completely separated mid-dorsally, with 11–12 setae near posterior to ventral margins (figure 11A). Surstylus very slightly pubescent only on medial mesal surface, not expanded at posteroventral corner, with about fi ve short prensisetae on distal margin, many thin setae on ventral margin, and a few ones on outer surface (figure 11B). Tenth sternite nearly bilobed, but not separated mid-dorsally, laterally narrowly fused to surstyli; lateral lobe-like process somewhat oblong (figure 11B). Anterior portion of hypandrium entirely thin (figure 11C). Vertical lobe of gonopod slightly sclerotized, protruded apically (figure 11C). Parameres separated from each other, lobe-shaped, each with apical, strongly sclerotized and lateral, less sclerotized processes and six to seven sensilla on medial mesal surface (figure 11D). Aedeagus separated into a pair of simple rods, each fused to base of paramere (figure 11D). Ejaculatory apodeme: apical plate with four pits per side; stalk thick, long (figure 11F).

M easurements: BL =2.78 mm; ThL =1.14 mm; WL =2.40 mm; WW =1.10 mm.

Indices: arb =4 / 2-3, avd =0.50, adf =1.30, w =1.50, F W / H W =0.36, ch / o = 0.13, prorb =0.94, rcorb =0.65, vb =0.38, dcl =0.62, presctl =0.54, sctl =1.05, sterno =0.87, orbito =2.10, dcp =0.34, sctlp =1.13, C =2.10, 4 c =1.67, 4 v =3.17, 5 x =1.25, ac =3.33, M =0.83, C3F =0.67.

Hol ot ype:, China: Changbaishan , Jilin, 11 July 1992, around human eyes, H.- W. Chen leg. (D BSC).

Distribution. China (Jilin).

R elationship. This species resembles A. lanceolata in the shape of vertical lobe of gonopod, but diVers from it in having the lateral, less sclerotized process on the paramere (strongly sclerotized in lanceolata ) and about fi ve short prensisetae on the surstylus (six to seven long ones) in addition to the diagnostic character.

Etymology. Patronym, after the name of the fi rst king of Manchuria originating from the area of Changbaishan, the type locality of this species.
