Cacopsylla (Cacopsylla) accincta View in CoL sp. n.

( Figs 1–8 View FIGURES 1 – 8 )

Adult. Coloration: Body brown, vertex yellowish brown, discal foveae and surrounding concave area dark brown. Genal processes blackish brown, apical half lighter. Antenna yellowish brown, with black apices on segments IV–VIII and segments IX–X entirely black. Ocelli light orange; compound eyes purplish red. Thoracic terga with dark brown stripes. Legs brown, femora darker. Fore wing transparent, veins brown. Abdominal segments blackish orange to mostly black with red hind margins. Male and female terminalia yellowish brown to black; female proctiger and subgenital plate with black pattern as shown in Fig. 6 View FIGURES 1 – 8 or entirely black.

Structure: Body glabrous and robust. Head strongly inclined from longitudinal body axis, slightly wider than mesoscutum. Vertex ( Fig. 2 View FIGURES 1 – 8 ) finely sculptured with microscopic setae and scaly micro structures that are relatively dense, narrow and smooth. Genal processes ( Fig. 1 View FIGURES 1 – 8 ) elongate cone-shaped, gradually tapering and moderately divergent apically, about as long as vertex along median suture, covered with long setae, apex relatively acute. Antenna long and slender; terminal setae ( Fig. 7 View FIGURES 1 – 8 ) subequal in length, slightly longer than antennal segment X. Metatibia with well developed basal spine, apical spurs arranged as 1+3+1. Fore wing ( Fig. 8 View FIGURES 1 – 8 ) oblong oval, widest in apical third; pterostigma short, ending in the middle of cell r1; cell cu1 relatively flat, curvature of vein Cu1a relatively smooth; surface spinules present in all cells, leaving narrow spinule-free stripes along veins, fields narrowing along wing margin in cells r2, m1, m2 and cu1, in c+sc sparse and scattered with the field reduced; 4 sets of radular spinules present in cells r2, m1, m2 and cu1, in r2 relatively reduced.

Male terminalia: Proctiger ( Fig. 3 View FIGURES 1 – 8 ) slightly arched, evenly covered with short setae. Paramere ( Figs 3, 5 View FIGURES 1 – 8 ) lamellar and relatively slender; apical tooth acute, strongly inflexed and projecting cephalad; erect or curved setae present on both inner and outer surface, almost evenly spaced on outer surface, denser and longer basally on inner surface and posterior margin, conspicuously denser on posterior than anterior margin; several long, erect and relatively thick setae growing from small tubercles on anterior margin, seemingly forming a row. Apical dilatation of aedeagus ( Fig. 4 View FIGURES 1 – 8 ) hook-shaped; sclerotised end tube of ductus ejaculatorius obliquely and straightly rising upward. Subgenital plate ( Fig. 3 View FIGURES 1 – 8 ) more or less quadrate in profile, with a band of moderately long setae extending from the middle of the dorsal margin towards the rear.

Female terminalia ( Fig. 6 View FIGURES 1 – 8 ): Proctiger with a relatively long apical part, dorsal margin weakly concave in profile, densely covered with setae that vary in length; apex of proctiger covered with relatively sparse peg setae. Ventral surface of subgenital plate evenly covered with short setae and peg setae.

Material examined. Holotype: male, dry mounted, China, Gansu, Beishan, Hanji, Linxia, on Pyrus ussuriensis 14.ix.2011, Ma Yanfang.

Paratypes: 8 male, 10 female with same data as holotype.

Non-paratypic specimens: Additional specimens from the same series are preserved in absolute ethanol.

Etymology. From Latin, accinctus = armed, referring to the coloration that’s like military suit and the robust body.

Remarks. This species resembles Cacopsylla mali , which is the type species of Cacopsylla s. str., in shape and setation of paramere, shape of cells and area of surface spinules in fore wing, all aspects of female terminalia, etc. For such reason, it is herein assigned to Cacopsylla s. str.
