Cyamophiliopsis xinjiangana sp. nov.

(Fig. 38‒44)

Description. Coloration: Body bicolor in overall view. Head and thorax appearing orange as dorsal surface is mostly covered by orange markings. Vertex white in ground color, pattern as in Fig. 38; genal processes white medially in front view, other parts orange; compound eyes grey, ocelli orange; antenna yellow, with brown apices on segments IV and VI, light brown apex on segment VII, black apex on segment VIII, and segments IX‒X entirely black. Thoracic terga white in ground color, mostly covered by orange stripes and markings; central portion of pronotum with three longitudinal stripes. Thoracic pleurites orange. Legs yellow, dorsal surface of fore- and mesofemora more or less darker. Forewing (Fig. 43) membrane whitish and translucent, with apical-posterior margin infuscate, gradually fading basally, veins yellow. Abdomen pale yellow or green. Male and female terminalia of the same color as abdomen, with tip of paramere black.

Structures: Head (Fig. 38) inclined from longitudinal body axis by about 80° and slightly wider than mesoscutum. Inner anterior corner of vertex protruding, outer anterior corner of vertex indistinct, gradually transiting into antennal base. Genal process cone shaped, slightly longer than half of the length of vertex along median suture, apex subacute; genal whip setae outstanding in length. Antenna slightly longer than head width and slender; higher based terminal seta about half as long as lower based one.

Pronotum relatively long longitudinally, and relatively less arched, strongly inclined from longitudinal body axis. Base of the anterior branch of dorsal bifurcation of propleural sulcus (Fig. 44) unclear, posterior branch longer than the anterior branch and clear; section ventral to pleural apophysis of propleural sulcus slightly coalescent. Forewing (Fig. 43) membranous; cell m1 conspicuously wider than m2 apically, cell cu1 less leaned backwards; surface spinules stout, covering most fields of all cells, leaving spinule-free bands along veins; fields of radular spinules as in Fig. 43. Metatibia with small and blunt basal spine.

Male terminalia: Proctiger (Fig. 39) tubular and arched, with setae that gradually grow denser apically. Paramere (Fig. 39 & 41) shorter than proctiger, base with a small lamellar lobe posteriorly; apical part small, with the lower corner relatively reduced; lateral lobe nearly triangular, margin slightly indented, dorsal margin with 4 or 5 thick blunt spines, and anterior margin with 2 or 3 thick setae on inner surface; a band of relatively smaller blunt spines present at transition line between lateral lobe and the main part of paramere on inner surface, along with several thick setae anteriorly. Distal segment of aedeagus (Fig. 40) long and slender; apical dilatation relatively large, with apex blunt; membranous sack relatively plump; end tube of ductus ejaculatorius strongly curved posteriorly. Subgenital plate (Fig. 39) hemispherical, with several setae on dorsal margin, and evenly spaced setae on ventral surface.

Female terminalia (Fig. 42): Apex of proctiger relatively acute, and moderately raised; apical process of proctiger with 1+1 longitudinal rows of relatively long setae and dozens of peg setae near lateral margins. Ventral bulge located in middle of ventral surface of subgenital plate, rather outstanding in profile; subgenital plate with peg setae bilaterally and short setae around ventral bulge and apically.

Materials examined. Holotype: ♂, dry mounted, China: Xinjiang: Yumin, Bashan Taste, 21.vii.2013, Luo Xinyu, on Spiraea hypericifolia . Paratypes: 8 ♀, same data; 7 ♂, 9 ♀, Xinjiang: Bole, Guaishiyu, 13.vii.2011, Luo Xinyu, on Spiraea hypercifolia .

Host plants. Spiraea hypericifolia .

Distribution. China: Xinjiang.

Etymology. Named after the type locality “Xinjiang”.

Remarks. This species resembles C. sarmatica in general aspect, differing in the smaller body size, the blunt basal spine of the metatibia, the shape of the lateral lobe of paramere and the shape of the ventral bulge of female subgenital plate.
