CENTROMERIA CURVA SP. NOV.

FIGS 2A , 13A – I , 14A – F

Type specimens. Holotype: ♂, China, Yunnan, Xishuangbanna, Menglun , 800 m a.s.l., 10.ix.2004, Z.S. Song ( IZCAS).

Paratypes: China, 3♂♂, 1♀, same data as holotype ; 1♀, Yunnan, Yiwubanna [Xishuangbanna], Menglun , 650 m a.s.l., 28.vii.1959, Z.F. Li ; 1♂, Yunnan, Xishuangbanna, Mengla, Mangzhuang , 2.viii.2004, Z.Z. Yang (all in IZCAS) .

Etymology. This new species name is derived from the Latin ‘ curvus ’, referring to its strongly upwardly curved head process.

Diagnosis. This species is very similar to C. speilinea in the speilinea clade, but can be separated from the latter by the longer cephalic process and the male genitalia, especially the different aedeagus. It may be distinguished from C. surgens by the phallobase with two pairs of ventral lobes.

Description. BL, ♂ 15.2 – 15.6 mm, ♀ 16.7 – 17.0 mm; HL, ♂ 1.6 – 1.7 mm, ♀ 1.7 – 1.8 mm; HW, ♂ 1.2 – 1.3 mm, ♀ 1.3 – 1.4 mm; TL, ♂ 12.3 – 12.5 mm, ♀ 13.6 – 13.9 mm.

Cephalic process in front of eyes strongly upturned and ascending at about 60°; in lateral view slightly longer than length from anterior margins of eyes to posterior margin of vertex ( Fig. 13B ). Vertex relatively narrow, posterior margin narrower than transverse diameter of eyes; in dorsal view ratio of length to width between eyes about 2.8: 1 ( Fig. 13A ); lateral carinae abruptly constricted and strongly upturned in front of eyes ( Fig. 13A ). Tegmina and hindwings as Fig. 10A, B . Fore femora with a minute spine near apex; hind tibiae with six or seven lateral spines; hind tarsomeres I with 12 or 13 apical teeth and tarsomeres II with 11 or 12 apical teeth.

Male genitalia with pygofer in lateral view large and broad, with ratio of ventral to dorsal width about 2.0: 1; posterior process near dorsal margin elongate, robust, and curved, apex acute ( Fig. 13E ). Gonostyles ( Fig. 13E ) more or less expanded towards apex, broadest subapically, apex bluntly rounded; upper process relatively short, acute apically. Aedeagus ( Fig. 13G – I ) large and robust, endosomal processes extended posteriorly and curved dorsoanteriorly, apex obtuse ( Fig. 13G ); phallobase membranous and strongly inflated, with one pair of apical lobes short and acute, directed dorsally on ventrolateral part, and one pair of additional lobes small and rounded on ventral base ( Fig. 13H, I ). Segment X in lateral view large and elongate, basal ventral margin projecting ventrally ( Fig. 13E ), in dorsal view with ratio of length to width near middle about 1.7: 1 ( Fig. 13D ).

Distribution. China (Yunnan).
