Anatkina leishanensis Yang, Meng & Yu , sp. nov.

( Figs 1–9 )

Type material. Holotype, ♂, Mt. Leigong, Leishan, Guizhou, 15. September. 2005, collected by Zizhong Li.

Length: ♂ 10.5 mm.

Coloration ( Figs 1–3 ). Head and thorax orange-yellow in dorsal view. Head with two rhomboid black spots at transition from crown to face and with blackish-brown linking line between them. Crown with transverse black band in concavity between ocelli; ocelli, eyes and antennae blackish-brown. Pronotum with anteromedian black spot and pair of large black spots posteriorly; scutellum with black spot bordering anterior margin near each of its basal angles, apical angle black. Forewing orange-red except for castaneous membranous apex; with eight black markings, one spot at base, one small spot at median portion of clavus near posterior margin of forewing, two large spots near base and apex of clavus respectively, two large spots at one-third and two-thirds of corium, one short longitudinal stripe at base of first apical cell, and one broad transverse band at subapical portion of forewing crossing all of apical cells. Face castaneous, frontoclypeus black in posterior half. Thoracic sternum black with yellowish-brown stripes; legs yellowish-brown; coxae, tarsi and pretarsi black; metathoracic legs with tibial apex black. Abdomen blackish-brown in ventral view; sternites with posterior margins pale.

External features. Head weakly produced, anterior margin almost square; median length of crown nearly 2/3 of interocular width; coronal suture distinct only at base of crown; crown concave between ocelli, with fovea between ocelli and eye; ocelli on imaginary line between anterior eye angles; lateral frontal sutures extending onto crown and attaining ocelli; frontoclypeus nearly flattened medially, muscle impressions distinct; transclypeal suture complete. Pronotum broader than head; anterior margin rounded; posterior margin concave medially; disk with transverse concavity at anterior portion, minutely punctuate at median and posterior portion; scutellum slightly convex behind transverse depression; forewing with apical membrane distinct, base of second apical cell slightly more proximal than base of third; hindleg with femoral setal formula 2:1:1.

Male genitalia. Pygofer ( Fig. 4 ) well produced posteriorly, in lateral view with posterior margin angularly convex; surface with macrosetae on posterior portion; pygofer process extending posterodorsally, apex strongly curved dorsally, hook-like, with minute denticles on outer margin and with acute tip. Subgenital plates ( Fig. 5 ) slender, abruptly narrowed on apical one-third portion and curved dorsad, apical half of surface with longitudinal uniseriate macrosetae medially and short microsetae. Aedeagus ( Fig. 6 ) with preatrium curved posteroventrad and articulated with paraphyses; shaft slender, slightly curved ventrally, extending posteriorly slightly beyond apex of paraphyses, apex acute. Paraphyses ( Fig. 7 ) slender, in lateral view bended dorsally at middle, apical portion slightly broader. Connective ( Fig. 8 ) U-shaped. Style ( Fig. 9 ) slender, apical portion abruptly narrowed, with hooked apex.

Etymology. The new species name refers to the type locality, Leishan.

Remarks. This new species resembles A. illustris ( Distant, 1908) , but it differs from the latter in that the crown has a larger black spot located between the ocelli ( Fig. 1 ), the frontoclypeus is mostly black ( Figs 2, 3 ), and the pronotum has a median anterior black spot in front of pair of posterior black spots ( Fig. 1 ). In addition, its male pygofer process, subgenital plates, preatrium, connective and styles differ in shape ( Figs 4–9 ).
