Doryphorina guizhouensis Zheng, Yang & Chen sp. n. Figs 6-10, 22-32

Measurement.

♂, BL: 17.7-17.9 mm; HL: 5.4-5.6 mm; HW: 1.6-1.7 mm; FWL: 10.5-10.9 mm.

Description.

Body greenish or greenish-ochraceous, marked with bluish green and reddish ochraceous on head and thorax.

Cephalic (Figs 6-8, 22, 24) process relatively slender, a little upturned, with ratio length to length of pronotum and mesonotum combined 2.2. Vertex (Figs 6, 8, 22) broad, media carina weakly, only distinct at apex and base, ratio of length to width between eyes 6.3. Frons (Figs 10, 23) elongate, intermediate carinae sub-parallel, nearly approaching frontoclypeal suture; median carina complete, length 5.5 times long than wide. Pronotum (Figs 6-8, 22, 24) distinctly shorter than mesonotum medially, media carina distinct, lateral carina replaced by two pits. Mesonotum (Figs 6, 8, 22) tricarinate on disc, lateral carinae straight, nearly parallel. Forewings (Figs 6, 25) hyaline, with ratio length to maximum width 3.1; stigma distinct, with 4-5 cells. Legs moderately elongate, fore femora not flattened and dilated, without spine; hind tibiae with 5 lateral black-tipped spines and 7 apical black-tipped teeth.

Male genitalia. Pygofer (Fig. 27) wider ventrally than dorsally, posterior margin with a blunt process. Anal tube (Fig. 29) in dorsal view, the apex broader than base, the ratio of length to width about 1.8. Gonostyles (Fig. 27) relatively small in lateral view, shorter than the apex of anal tube in lateral view, inner face with numerous setae in ventral view. Aedeagus (Figs 30-32) with 1 pair of short endosomal processes, without extending from phallotheca. Phallobase (Figs 30-32) sclerotized and pigmented, with 2 pairs of apical membranous lobes: dorsal apical lobes (Fig. 31) long and slender, with 4 long apical spines each, ventral lobes (Fig. 31) with 2 pairs of apical lobes connected, not produced laterally, apex and base with about 16-19 long spines totally in ventral view.

Female. Unknown.

Type material.

Holotype ♂, China: Guizhou, Congjiang, 24 Jul. 2005, coll. Deyan Ge. Paratype, 1♂, China: Guizhou, Libo, Aug. 1997, coll. Zizhong Li (both in GUGC).

Distribution.

China (Guizhou).

Diagnosis.

This species is similar to Doryphorina minor , but can be distinguished from the later by phallobase ventral lobes (Fig. 31) with 2 pairs of apical lobes connected, not produced laterally, apex and base with about 16-19 long spines totally in ventral view (ventral part with two pairs of V-shaped elongate apical lobes, directed laterally and ventrally, each with 4-5 long spines in ventral view in Doryphorina minor ).

Etymology.

This new species name refers to the type locality, Guizhou Province.
