Cacopsylla (Hepatopsylla) maculatili Li

( Figs 52–59 )

Cacopsylla maculatili Li, 2011: 880 .

Adult. Coloration: Body orange. Vertex yellow, discal foveae dark brown; fore margin, lateral margin and area alongside the median suture orange. Genal process brownish yellow. Compound eyes grey; ocelli yellow. Antennae yellow, with black apices on segments IV–VII and segments VIII–X entirely black. Thoracic terga yellow to orange, with brown stripes. Legs yellow, femora and apical tarsal segments dark brown. Fore wing ( Fig. 59 ) transparent, veins yellow; marking near apex of claval suture dark brown, extending to wing base in cell cu2, growing lighter meanwhile. Abdomen alternates orange with brown. Female terminalia brownish yellow, with black patterns in proctiger and subgenital palte as is shown in Fig. 57 .

Structures: Body glabrous and robust. Head moderately inclined from longitudinal body axis, about as wide as mesoscutum. Vertex ( Fig. 53 ) finely sculptured with microscopic setae and scaly micro structures that are relatively small, smooth, and moderately spaced from each other; discal foveae rather deep. Genal processes ( Fig. 52 ) cone-shaped and rather robust, relatively blunt and moderately divergent apically, about as long as vertex along median suture, covered with long setae. Antenna long and slender, terminal setae ( Fig. 58 ) not as long as each other, the longer one about 1.5 times as long as the shorter one, and slightly longer than antennal segment X. Metatibia with sharp basal spine, apical spurs arranged in (1+3+1). Fore wing ( Fig. 59 ) oval, widest in about the apical third; pterostigma long, ending in the apical third of cell r1; cell cu1 relatively tall, turning of vein Cu1a relatively smooth; two small fields of scattered surface spinules present in only cell cu2, one in the base, the other near apex of claval suture; 4 sets of radular spinules present in cells r2, m1, m2 and cu1, in r2 less developed.

Male terminalia rather small. Proctiger ( Fig. 54 ) simple, densely covered with short setae. Paramere ( Figs 54 & 56 ) lamellar, relatively robust, apex rounded and projected caudad, posterior margin thickened; setae present in both inner and outer surface, much denser and longer in posterior margin than in anterior margin. Apical dilatation ( Fig. 55 ) of aedeagus spoon-shaped; sclerotised end tube of ductus ejaculatorius projecting back-upwards. Subgenital plate ( Fig. 54 ) near quadrate, with several setae that vary in length in dorsal margin and relatively dense short setae in ventral surface.

Female terminalia ( Fig. 57 ) relatively short. Proctiger moderately convex dorsally, with a shallow transverse gap in about the middle, lying cephalad to the convex part; basal-most part moderately rising upward; dense short setae present in dorsal-lateral surface; laterally and apex of the apical 2/3 of apical part covered with peg setae, with the involved field surrounded by fields of short setae. Subgenital plate near triangular, with ventral surface covered with short setae and peg setae.

Material examined. Holotype: male, slide mounted, China, Liaoning, Shenyang, v.1986, Sun Lihua, on Pyrus ussuriensis .

Paratypes: 3 female, with same data as holotype.

Remarks. This species resembles C. qiuzili in the paramere shape (robust, with blunt apex projecting caudad, and produced posterior margin) and female proctiger shape. The two species can be distinguished by different body size, shape of genal processes, distal segment of aedeagus and fore wing shape, colour and spinulation, and setation of paramere posterior margin of C. maculatili is conspicuously longer and denser than that of C. qiuzili .
