Apophylia yangi sp. nov.

( Figs. 1 , 6 )

Type locality. China, Xizang, Longzi.

Type material. HOLOTYPE: J, CHINA: XIZANG, Longzi, 3340 m a.s.l., 25.vii.1981, Xinnian Li leg. ( IZCAS). PARATYPES: 1 J 1 ♀, same label data as holotype (♀ in IZCAS and J in JBCB); 1 ♀, XIZANG, Longzi, vii.1981, without the name of collector ( IZCAS). The specimens are provided with additional printed red labels: ‘HOLOTY- PUS [or PARATYPUS], / Apophylia / yangi sp. nov., / det. Bezděk & Zhang 2006’.

Description. Body length: males 5.20-5.30 mm (holotype 5.30 mm); females 6.15-6.70 mm.

Male. Body flattened, parallel, densely pubescent. Head black, mouthparts brownish. Antennomeres 1-3 yellow, antennomere 1 darkened dorsally, antennomeres 2 and 3 slightly darkened apically, antennomere 4 dark with paler base, antennomeres 5-11 black. Pronotum black with yellow extreme margins. Scutellum black, elytra metallic dark green. Prosternum yellow. Meso-, metasternum and abdomen black. Legs black, trochanters and bases of femora brownish.

Labrum transverse, covered with several pale setae, anterior margin slightly sinuate.Anterior part of head semiopaque, sparsely covered with pale setae. Frontal tubercles small, subtriangular, lustrous. Interantennal space with small deep groove. Vertex with slightly impressed median line, dull, coarsely and densely punctate, and covered with short pale hairs. Antennae slender, 0.70 times as long as body, length ratios of antennomeres 1-11 equal to 18-10-19-23- 14-14-12-12-10-10-13. Last three antennomeres very short, nearly as long as wide.

Pronotum transverse, 1.70 times as broad as long, widest at anterior third, slightly narrowed anteriad and posteriad, with two lateral depressions. Surface covered with fine punctures, lustrous, lateral depressions semiopaque.Anterior and posterior margins almost straight, thinly bordered. Lateral margins rounded, indistinctly bordered. Anterior angles rounded, posterior angles obtusely angulate; all angles with small distinct teeth bearing one long pale seta.

Scutellum subtriangular with widely rounded apex, semiopaque, densely covered with small punctures and short pale hairs.

Elytra parallel. Humeral calli well developed. Elytral surface dull, covered with small and very dense confluent punctures and very short pale hairs. Epipleura distinct, narrow, disappearing before apex. Macropterous.

Ventral surface semiopaque, finely punctate, and covered with pale hairs. Last visible ventrite with subtriangular incision. Pygidium with very small apical incision.

Hind tarsomere 1 ca 1.05 times as long as two following tarsomeres combined. Claws bifid.

Shape of aedeagus as in Fig. 1 .

Female. Pronotum 1.75-1.80 times as broad as long. Both last ventrite and pygidium not emarginate. Middle and hind tarsomeres 1 thin. Claws appendiculate.

Variability. One female with the yellow margins of pronotum somewhat wider and the pronotal surface not as lustrous as in the other three specimens.

Differential diagnosis. Owing to the coloration of the pronotum, A. yangi sp. nov. resembles other Apophylia species with extended black pattern on the pronotum – A. grandicornis (Fairmaire, 1888) , A. frischi Bezděk, 2003 , and females of A. variicollis Laboissière, 1927 . However, all these species have a yellow anterior part of the head (completely black in A. yangi sp. nov.), at least partly yellow legs, and a dull or semiopaque pronotum.

Etymology. The species is dedicated to Prof. Xing-ke Yang ( China, Beijing), an excellent specialist in Chinese Galerucinae.

Bionomics. Unknown.

Distribution. China: Xizang.
