Structures: Head (Fig. 16) inclined from longitudinal body axis by about 70°, slightly wider than mesoscutum; inner apical corners of vertex slightly protruding, drop between vertex and gena not very conspicuous, area above antennal insertion not depressed. Genal processes conical, slightly longer than half of vertex along median suture, apex subacute (narrowly rounded), genal whip setae outstanding in length. Antenna short, not conspicuously longer than head width.
Pronotum relatively long longitudinally, and relatively less arched, strongly inclined from longitudinal body axis. Both branches of dorsal end of propleural suture (Fig. 22) clear, proepimeron much larger than proepisternum. Forewing (Fig. 21) membranous; cell cu1 relatively broader and less leaned backwards; surface spinules covering most fields of cells, leaving spinule-free bands along veins that gradually grow narrower apically; fields of radular spinules as shown in Fig. 21. Metatibia with blunt basal spine.
Male terminalia: Proctiger (Fig. 17) tubular, strongly curved caudad, covered with setae that gradually grow denser apically. Paramere (Figs 17 & 19) shorter than proctiger, apical part rather broad; base with a lamellar lobe near posterior margin; lateral lobe relatively large, its posterior margin indented, inner surface with 20 or more curved long spines, which are longer and thicker marginally and dorsally. Distal segment of aedeagus (Fig. 18) long, slender and nearly straight; apical dilatation small, apex rounded; end tube of ductus ejaculatorius curved posterior-dorsally. Subgenital plate (Fig. 17) semi oval, dorsal margin with a longitudinal band of setae, apical 2/3 of ventral surface with evenly spaced setae.
Female terminalia (Fig. 20): Apex of proctiger distinctly curved dorsally; apical process of proctiger with 1+1 longitudinal rows of relatively long setae and dozens of peg setae near lateral margins. Ventral bulge of subgenital plate outstanding; subgenital plate with peg setae bilaterally and short setae around ventral bulge and apically.
Material examined. Holotype: ♂, dry mounted, China: Xinjiang: Altay, Xiaodonggou Forest Park, 30.vi.2011, Luo Xinyu, on Spiraea hypericifolia. Paratypes: 4 ♂, 4 ♀, same data; 1 male, Xinjiang: Yumin, Bashan Taste, 21.vii.2013, Luo Xinyu, on Spiraea hypericifolia.
Host plant. Spiraea hypericifolia.
Distribution. China: Xinjiang.
Etymology. The species name is given because of the superficial resemblance with C. fasciata, “pseudo-” = “fake”.
Remarks. This species possesses the same forewing pattern as C. fasciata. However, the illustrations of Baeva (1985) of C. fasciata show that the lateral lobe of the paramere bears sclerotised spines on margin and boundary with the main part, a different pattern from the new species; C. pseudofasciata also possesses a conspicuously shorter female subgenital plate than C. fasciata.
