( Figs. 2 , 7 )

Type locality. China, Guangxi, Longsheng, Tianpingshan Mt.

Type material. HOLOTYPE: J, CHINA: GUANGXI, Longsheng, Mt. Tianpingshan , 740 m a.s.l., 5.vi.1963, Yongshan Shi leg. ( IZCAS) . PARATYPE: 1 ♀, GUANGXI, Longsheng, 1150 m a.s.l., 18.vi.1963, Shuyong Wang leg. ( IZCAS). The specimens are provided with additional, printed, red label: ‘ HOLOTYPUS [or PARATYPUS], / Apophylia / cheni sp. nov., / det. Bezděk & Zhang 2006’.

Description. Body length: male (holotype) 6.05 mm; female 6.55 mm.

Male. Body flattened, parallel, densely pubescent, dull. Head black, anterior part of head and mouthparts yellow, mandibles brown. Frontal tubercles black. Antennomeres 1-3 yellow and slightly darkened dorsally, gradually darkened from antennomere 4, last five antennomeres black. Pronotum, scutellum and underside black, elytra metallic green, legs yellow, tarsi infuscate.

Labrum transverse, covered with several pale setae, anterior margin distinctly sinuate. Anterior part of head with microsculpture, semiopaque, sparsely covered with pale setae. Frontal tubercles small, subtriangular, and semiopaque. Vertex dull, coarsely and densely punctate, covered with short pale hairs. Antennae filiform, 0.80 times as long as body, length ratio of antennomeres 1-11 equal to 21-10-18-23-20-20-18-18-18-15-17.

Pronotum transverse, 1.90 times as broad as long, widest at anterior third, dull, densely covered with small punctures and pale hairs; anterior marginal ridge sparsely covered with coarse punctures. Surface with two large lateral depressions. Anterior margin widely and shallowly concave, lateral margins rounded, posterior margin straight with small indicated median emargination. Anterior marginal ridge interrupted in the middle. Anterior and posteri- or margins thinly bordered, lateral margins indistinctly bordered. Anterior angles rounded with very small teeth, posterior angles obtusely angulate with distinct teeth; all angles 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 short pale hairs. Epipleura narrow, disappearing before apex. Macropterous.

Ventral surface semiopaque, finely punctate, covered with pale hairs. Last visible ventrite with semicircular emargination.

Hind tarsomere 1 long, 2.25 times as long as the following two tarsomeres combined. Claws bifid.

Shape of aedeagus as in Fig. 2 .

Female. Hind tarsomere 1 only 1.75 times as long as the following two tarsomeres combined. Last ventrite not emarginate. Claws appendiculate.

Differential diagnosis. Owing to the filiform antennae, black frontal tubercles and yellow anterior part of the head, A. cheni sp. nov. is most similar to A. excavata Bryant, 1954 from Myanmar and Thailand, A. kimotoi Bezděk, 2003 from Japan, and A. weisei (Jacoby, 1896) from Java and Sumatra. Males of A. cheni sp. nov. are easily distinguished from other similarly coloured species by the unique left latero-apical incision of the aedeagus ( Figs. 2-5 ).

Etymology. The species is dedicated to Prof. Sicien Chen, an excellent specialist in Chinese Chrysomelidae and a pioneer of Chinese studies in Coleoptera .

Bionomics. Unknown.

Distribution. China: Guangxi.
