Etymology.

The species name is a patronym in honor of Prof. Xianjin Peng (Changsha, China), who has made significant contributions to the taxonomy of Chinese salticids; noun (name) in genitive case.

Diagnosis.

The new species resembles Phintelloides versicolor (C. L. Koch, 1846) and Phintella leucaspis (Simon, 1903) in the copulatory organs, but it can be easily distinguished by the straight embolus (Fig. 12B ) vs. curved in P. versicolor and Phintella leucaspis ( Żabka, 1985: figs 83, 88, 91 and Bohdanowicz and Prószyński 1987: fig. 214) and the laterally located, widely separated copulatory openings, separated from each other by more than 3 times the spermathecal width (Fig. 13A ) vs. anteriorly located copulatory openings, separated slightly more than 2 times the spermathecal width in P. versicolor ( Żabka, 1985: fig. 93).

Description.

Male (Figs 12 , 13C, D, F, G ). Total length 3.57. Carapace 1.71 long, 1.40 wide. Abdomen 1.83 long, 1.19 wide. Clypeus 0.10 high. Eye sizes and inter-distances: AME 0.42, ALE 0.23, PLE 0.22, AERW 1.25, PERW 1.21, EFL 0.89. Legs: I 3.73 (1.15, 1.45, 0.75, 0.38), II 3.49 (1.13, 1.23, 0.75, 0.38), III 3.94 (1.25, 1.28, 0.98, 0.43), IV 4.22 (1.33, 1.45, 1.01, 0.43). Carapace dark brown, with a fan-shaped yellow area on anterior thoracic part and pair of yellow lateral bands with white scales, covered with white and yellow scales anteriorly. Fovea longitudinal, red, thin, bar shaped. Chelicerae yellow-red to dark brown, with 1 retromarginal tooth and 2 promarginal teeth. Endites dark, somewhat greenish, pale entally. Labium colored as endites. Sternum pale, with white and brown setae. Legs green-brown to dark brown except tarsi, metatarsi yellow and coxae, trochanter of legs II, III, IV pale. Abdomen sub-oval, dorsum gray-white to dark green, pale and dotted laterally, with longitudinal dark green band over entire surface medially; venter colored as dorsum, with pair of dotted lines medially.

Palp (Fig. 12A-C ): femur about 2.5 times longer than wide, dark brown proximal half; tibia almost as long as wide, with tapered retrolateral tibial apophysis, broad basally, slightly curved distally, pointed apically; cymbium about 2.5 times longer than wide in ventral view, bearing white scales dorsally; bulb inflated, with digitiform baso-retrolateral tegular bump; embolus straight, longer than retrolateral tibial apophysis, originating from apical portion of bulb, tip directed towards about 12:30 o’clock in ventral view.

Female (Fig. 13A, B, E ) Total length 4.27. Carapace 1.77 long, 1.56 wide. Abdomen 2.26 long, 1.51 wide. Clypeus 0.11 high. Eye sizes and inter-distances: AME 0.44, ALE 0.26, PLE 0.25, AERW 1.42, PERW 1.39, EFL 1.03. Legs: I 3.74 (1.18, 1.43, 0.73, 0.40), II 3.70 (1.15, 1.42, 0.73, 0.40), III 4.19 (1.33, 1.40, 1.01, 0.45), IV 4.71 (1.50, 1.63, 1.13, 0.45). Carapace similar to that of male except pale. Abdomen dark brown dorsally, with 3 longitudinal, pale bands anteriorly, 3 transverse, pale bands medially, irregular pale markings and dots posteriorly, pair of pale spots at terminus.

Epigyne (Fig. 13A, B ) slightly wider than long; atrium large, with an arc-shaped anterior ridge; copulatory openings slit-shaped, located at lateral edges of atrial ridge, separated by almost 3 times the spermathecal width; copulatory ducts short, straight, oblique, connected to anterior edges of spermathecae, with short accessory glands at terminus; spermathecae almost oval, overlapping entally, anteriorly with tube-shaped extensions connected to lamellar fertilization ducts.

Distribution.

Known only from the type locality in Yunnan, China.

Comments.

The male and female are considered to be the same species because they were collected from the same site without other candidates and have copulatory organs similar to Phintelloides versicolor . Phintella leucaspis (Simon, 1903) shares a very similar palp with Phintelloides versicolor and the new species, thus it most likely belongs to Phintelloides .
