Cyamophiliopsis spinosa sp. nov.

( Fig. 31‒37 )

Cyamophiliopsis fasciata Löw sensu Li 2011: 679 , misidentification.

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. 31 ; genal processes yellow medially in front view, other areas orange; compound eyes grey, ocelli orange; antenna yellow, with brown apices on segments IV and VII, black apices on segments VI and 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. 36 ) membrane yellowish and translucent, with apex of r2, m1, apical half of m2, cu1, and apical 1/4 of cu2 infuscate, gradually fading basally, veins yellow. Abdomen pale yellow. Male and female terminalia of the same color as abdomen, with tip of paramere black.

Structures: Head ( Fig. 31 ) inclined from longitudinal body axis by about 70° and slightly wider than mesoscutum. Inner anterior corner of vertex protruding, outer anterior corner of vertex indistinct, gradually transiting into antennal base. Genal processes cone-shaped, about 0.7 times as long as vertex along median suture, conspicuously dilated, with lateral margins from front view slightly convex instead of slightly emarginated, apex subacute; genal whip setae outstanding in length. Antennae partially missing in examined specimens.

Pronotum relatively long longitudinally, strongly arched, strongly inclined from longitudinal body axis. Anterior branch of the dorsal bifurcation of propleural sulcus ( Fig. 37 ) short and obscure, posterior branch about twice as long as the anterior branch and distinct. Forewing ( Fig. 36 ) membranous; cell m1 conspicuously wider than m2 apically, cell cu1 rather wide apically; surface spinules stout, covering most fields of all cells, leaving spinulefree bands along veins that gradually grow narrower apically; fields of radular spinules as in Fig. 36 . Metatibia with small and blunt basal spine.

Male terminalia: Proctiger ( Fig. 32 ) tubular and arched, with setae that gradually grow denser apically. Paramere ( Fig. 32 & 34 ) shorter than proctiger, base with a small lamellar lobe posteriorly; apical part small, with apex relatively strongly curved inwards; lateral lobe nearly triangular and large, with dorsal margin strongly indented, inner surface of dorsal margin and apical angle with 6 or 7 thick spines which are with an acute and transparent tip each, and anterior margin with 2 or 3 thick setae on inner surface; a band of about 20 relatively smaller subacute spines present at the transition line between lateral lobe and the main part on inner surface. Distal segment of aedeagus ( Fig. 33 ) long and slender; apical dilatation relatively large and elongated, with apex relatively long stretching and rounded; membranous sack relatively plump; end tube of ductus ejaculatorius stretching dorsally-posteriorly. Subgenital plate ( Fig. 34 ) hemispherical, with rather wide dorsal-caudal thickened band; a longitudinal band of several setae present in dorsal margin, ventral surface with evenly spaced setae.

Female terminalia ( Fig. 35 ): Field surrounding perianal ring waved; apex of proctiger relatively acute, moderately raised; apical process of proctiger with 1+1 longitudinal rows of relatively long setae and dozens of peg setae near lateral margins. Subgenital plate relatively elongated, in profile with relatively inconspicuous ventral bulge located in posterior 1/3; peg setae present bilaterally and short setae present around ventral bulge and apically.

Material examined. Holotype: ♂, slide mounted, China: Inner Mongolia: Ewenki, Honghuaerji, 780 m, 21.viii.1986, Li Fasheng. Paratypes: 2 ♀, same data.

Host plant. Spiraea aquilegifolia (Li 2011) .

Distribution. China: Inner Mongolia.

Etymology: Name after the inner surface of paramere that is beset with many sclerotised spines, “spinosus” = “bearing spines”.

Remarks: This species resembles Psylla spiraeae Konovalova, 1979 in body size, forewing shape, venation and coloration. However, according to Konovalova’s description, P. s pi r ae a e possesses rather retracted fields of surface spinules, which is the main difference with the new species.
