ABSTRACT
A new species of the crab spider Pharta tangi sp. nov. (male
and female) from Guizhou province in China is described.
Photos of body and copulatory organs as well as dierence
comparison between the new and closely related species are
given. Locality map is also provided.
Introduction
Pharta is a poorly known genus relatively although it was revised by Benjamin
(2011). Up to now, only eight species have been described from South-East Asia
(World Spider Catalog 2016). e type species P. bimaculata was reported by
orell in 1891, P. brevipalpus was originally described as Epidius brevipalpus
(Simon 1903). P. gongshan, P. nigra, and P. tengchong were originally placed in
the genus Sanmenia (Yang et al. 2006; Tang et al. 2009). Pharta was revised by
Benjamin (2011). ree members were added by Sen et al. (2012) and Benjamin
(2014). So far, two species were described from China: P. gongshan and P. tengchong.
While examining the specimens collected from Fanjingshan National Nature
Reserve (Guizhou province, southwest China), a new species of genus Pharta
was recognized. Diagnosis and description of body and copulatory organs of the
species are given in this paper.
Material and methods
All specimens were xed in 75% ethanol. Color photos were taken with a Canon
PowerShot G12 digital camera mounted on an Olympus SZX16. Compound focus
images were generated using Helicon Focus soware (3.10).
All measurements were given in millimeters. Leg measurements are giving as:

Taxonomy
Genus Pharta orell, 1891
Pharta tangi sp. no v.
Figures 1–3
Type materials: Holotype: ♂, CHINA: Guizhou: Tongren City, Songtao County,
Wuluo Township, Taoyuan Village, 28°00′0113N, 108°46′4784E, 880m, 31 July

Liao leg.
Paratypes: 3♀, same data as holotype.
Etymology: e specic name is in honor of Doctor Guo Tang, an arachnological
scholar on omisidae of China.
Diagnosis: e male of the new species is similar to P. koponeni Benjamin 2014
in having similar shapes of ventral tibial apophysis and conductor, but can be dis-
tinguished from the latter by: (1) length of palp tibia about 1.5times longer than
its width (Figures 1(C–E), 2(A–B)) versus about as long as wide in P. koponeni;
(2) ventral tibial apophysis curved slightly at middle part in ventral view (Figures
1(C), 2(B)) versus without curved in P. koponeni; and (3) conductor located in
alveolus, not extended beyond the promargin of cymbium in ventral view (Figures
1(C), 2(B)) versus part of conductor beyond the pro-margin of cymbium in P.
koponeni. e female of the new species is similar to P. gongshan, but can be dis-
tinguished from the latter by: (1) atrial intermediate margin clear (Figures 1(F),
2(C)) versus indistinct in P. gongshan; (2) copulatory openings invisible versus
visible in P. gongshan; and (3) fertilization ducts positioned transversally (Figure
2(D)) versus stretching longitudinally in P. gongshan.
Description. Male: Total length 3.35, Carapace 1.62 long, 1.50 wide. Abdomen
1.73 long, 1.35 wide. Carapace yellowish brown, median area darker. AER and
PER both recurved, ocular area covered with several brown hairs. Eye sizes and
interdistances: AME 0.05, ALE 0.13, PME 0.10, PLE 0.16. AME–AME 0.08, AME–
ALE 0.06, PME–PME 0.10, PME–PLE 0.09. MOA 0.17 long, anterior width 0.14,
posterior width 0.11. Carapace groove and fovea indistinct, radial grooves shallow.
Endites longer than wide, pro-marginal scopula present. Labium dark brown,
wider than long, the terminal with bristles. Sternum almost cordiform, covered
with yellow hairs. Legs yellow to yellowish brown, trochanters, coxae, and femurs
lightly pale. Dorsum of abdomen (Figure 1(A)) oval, scattered with small white
patches, anterior middle part with three pairs of large white patches, median area

with two pairs of large dark brown patches, covered with sparse black hairs. Venter
gray, with some gray patches medially.

lateral trichobothria, the ventral apophysis slightly curved at middle part and the

from the base of bulb, the proximal atted, and then becoming thinner suddenly,
more than 2/3 length was covered by conductor. Conductor originated from the
