Ma, JXZ06#011 (UBC-SEM AR00168). Paratypes: 1 female, CHINA: GUANGXI: Pingxiang City, Longzhou County, Daqingshan Forestry Center, 22.299° N, 106.700° E, elev. 806–989 m, 15 May 2006, coll. J. Zhang, M. S. Zhu, W. G. Lian & H. Q. Ma, JXZ06#005 (UBC-SEM AR00169); 1 female, same data as previous.

Etymology. The specific epithet is a patronym in honor of Dr. Xianjin Peng, who has made great contributions in studying the jumping spider fauna of China.

Diagnosis. Differs from Chinophrys liujiapingensis ( Yang & Tang, 1997) , the other species of this genus, in the presence of six promarginal teeth on the chelicera ( Fig. 5 ; four in C. liujiapingensis ), the shape of the proximal tegular lobe and the longer retrolateral tibial apophysis of the male palp ( Figs 3–4 ).

Description. Male (holotype, UBC-SEM AR00168). Carapace length 2.5; abdomen length 2.4. Chelicera ( Fig. 5 ): yellow brown; promargin with six small teeth, retromargin with a six-cuspid fissident tooth. Palp ( Figs 3–4 ): gray brown. Embolus long and coiled for about a circle; palpal tibia with a long finger-like retrolateral apophysis and a round ventral bump. First tibia with three pairs of ventral macrosetae; first metatarsus with two pairs of ventral macrosetae. Measurements of legs: I 5.1, II 4.5, III 5.1, IV 5.2. Color in alcohol ( Fig. 1 ): carapace dark brown, with some white scales; abdomen dark gray brown, with light yellow dots and chevron-like markings, anterior and median part with a relatively sclerotized area; legs dark brown.

Female (paratype, UBC-SEM AR00169). Carapace length 2.4 (variation: 2.4–2.5, n=2); abdomen length 2.9. Chelicera: with four small teeth on promargin and one four-cuspid tooth on retromargin. First tibia with three pairs of ventral macrosetae; first metatarsus with two pairs of ventral macrosetae. Measurements of legs: I 3.7, II 3.5, III 4.5, IV 4.7. Epigynum ( Fig. 8 ): median septum narrow with posterior end wider; with coiled grooves within window. Vulva ( Fig. 9 ): copulatory duct long and thin; spermatheca with a spherical head region and a kidney-shaped body region. Color in alcohol ( Fig. 2 ): similar to that of male, but legs paler in color with brown annuli.

Natural history. Specimens were found by beating foliage in forest and at forest edge.
