Diagnosis

The male of Phintella jiugongensis sp. nov. closely resembles that of P. panda Huang, Wang & Peng, 2015 , but differs in: (1) the lamellar process being about two times as long as wide ( Fig. 17A ), whereas about four times as long as wide in P. panda ( Fig. 22A ); (2) the tegulum having a knob below the embolic base ( Fig. 17A–B ), whereas absent in P. panda ( Fig. 22A–B ). The female also resembles that of P. panda in having a similar epigyne, but it can be distinguished by the following: (1) the copulatory openings being below the anterior-most spermathecal margins ( Fig. 18A–B ), whereas anterior to spermathecae in P. panda ( Fig. 23A–B ); (2) the distance between two protrusions of the basal epigynal plate being almost equal to spermathecal width ( Fig. 18A–B ), whereas about half the spermathecal width in P. panda ( Fig. 23A–B ). The female also resembles P. linea (Karsch, 1879) in the general shape of the epigyne, but it can be easily distinguished by the copulatory openings, which are below the anterior-most spermathecal margins and separated from each other about half the spermathecal width ( Fig. 18A–B ), whereas anterior to spermathecae and separated from each other by more than the spermathecal width in P. linea ( Prószyński 1973: figs 42–43).

Etymology

The species name is derived from the name of the type locality, Jiugong Mountain National Nature Reserve; adjective.

Legs: I 4.88 (1.38, 0.75, 1.25, 1.00, 0.50), II 3.98 (1.20, 0.58, 0.95, 0.75, 0.50), III 4.64 (1.40, 0.58, 1.03, 1.13, 0.50), IV 5.01 (1.50, 0.53, 1.25, 1.23, 0.50).

HABITUS. Carapace brown to dark brown, covered with white and dark scale-like setae and brown setae, with yellow area bearing white scale-like setae medially on thorax, a pair of later-marginal yellow bands, and two clusters of white scale-like setae between ALEs and PLEs ( Fig. 18C, F ). Chelicerae with one retromarginal tooth and two promarginal teeth, and distal flange of fang ( Fig. 18G ). Legs pale to dark brown somewhat mingled with green. Abdomen sub-oval, dorsum green-brown anteromedially, with alternate dark brown and pale yellow stripes posteromedially; venter with green-brown, central, longitudinal band extended from epigastric furrow to terminus ( Fig. 18C–D ).

PALP. Tibia wider than long; RTA strongly sclerotized, tapered, broadened at base, slightly curved medially in ventral view and almost triangular at distal half in retrolateral view; bulb elongated, with sub-triangular posterior lobe and small knob below embolic base; tegular bump lamellar, medio-retrolaterally located; lamellar process about two times as long as wide; embolus short, strongly sclerotized, directed towards about 2 o’clock position apically in ventral view ( Fig. 17 ).

Female (paratype, TRU-JS 0153)

MEASUREMENTS. Total length 3.96. Carapace 1.64 long, 1.38 wide. Abdomen 2.38 long, 1.72 wide. Eye sizes and interdistances: AME 0.45, ALE 0.25, PLE 0.23, AERW 1.32, PERW 1.24, EFL 0.89. Legs: I 3.54 (1.08, 0.60, 0.80, 0.68, 0.38), II 3.39 (1.05, 0.53, 0.78, 0.65, 0.38), III 3.74 (1.13, 0.53, 0.78, 0.90, 0.40), IV 4.34 (1.28, 0.53, 1.05, 1.05, 0.43).

HABITUS. Similar to that of male except paler in color ( Fig. 18E ).

EPIGYNE. With broad, bow-shaped basal plate and a pair of anterior atrial ridges inner to copulatory openings; copulatory openings almost round, located anteriorly; copulatory ducts strongly curved more than 90° posteromedially, with short accessory glands at terminus; spermathecae pear-shaped, separated from each other by one-seventh the spermathecal width; fertilization ducts lamellar, anterior-laterally extended ( Fig. 18A–B ).
