Description

Male (Fig. 1 , Fig. 2 C, D, F and G). Total length 2.93. Carapace 1.74 long, 1.39 wide. Abdomen 1.26 long, 0.98 wide. Eye sizes and inter-distances: AME 0.44, ALE 0.22, PME 0.21, AERW 1.26, PERW 1.24, EFL 0.83. Legs: I 4.21 (1.25, 0.60, 1.13, 0.83, 0.40), II 3.54 (1.10, 0.48, 0.88, 0.75, 0.33), III 4.14 (1.25, 0.53, 0.95, 1.03, 0.38), IV 4.44 (1.30, 0.53, 1.05, 1.13, 0.43). Carapace elevated, dark brown to dark, covered with clusters of white scale-like setae between PLEs and PMEs, with pair of sub-triangular dark patches inner to PMEs, irregular median yellow area and pair of oval dark patches bearing dense dark scale-like setae posteriorly on thorax; fovea dark red, longitudinal. Chelicerae dark yellow, mingled with green-brown, with two promarginal teeth and one larger, medially located retromarginal tooth. Endites sub-square, bearing scopulae on antero-inner portions. Labium tapered. Sternum yellow to green-brown. Legs green-brown to dark brown, except metatarsi and tarsi III and IV pale. Abdomen almost oval, dorsum setose, with median, transverse white setal band; venter dark.

Palp (Fig. 1 A-C): tibia slightly wider than long in retrolateral view; retrolateral tibial apophysis strongly sclerotised, tapered, with pointed tip slightly curved ventrally; cymbium about 1.8 times longer than wide; bulb elongated; posterior lobe posteriorly extended, with blunt end; tegular bump sub-triangular, near distal portion of retrolateral tibial apophysis; lamellar process anteriorly located, near half-round; embolus short, strongly sclerotised, originating from antero-prolateral portion of bulb, slightly curved at base and with rather blunt end.

Female (Fig. 2 A, B and E). Total length 3.01. Carapace 1.48 long, 1.15 wide. Abdomen 1.61 long, 1.07 wide. Eye sizes and inter-distances: AME 0.39, ALE 0.20, PME 0.18, AERW 1.13, PERW 1.13, EFL 0.78. Legs: I 2.71 (0.85, 0.43, 0.63, 0.50, 0.30), II missing, III 3.16 (1.00, 0.43, 0.65, 0.75, 0.33), IV 3.56 (1.08, 0.40, 0.83, 0.90, 0.35). Carapace (Fig. 2 E) pale to yellow, with similar dark patches as in male. Chelicerae yellow, with two promarginal teeth and one retromarginal tooth almost equal in size. Endites coloured as chelicerae. Labium pale. Legs pale, spiny. Abdomen elongate-oval, dorsum (Fig. 2 E) pale to yellow, with two discontinuous, transverse dark stripes; venter pale, with terminal green-brown patch.

Epigyne (Fig. 2 A and B): wider than long; copulatory openings mediolaterally located on atrium and opened laterally; copulatory ducts transversely extended at origin and then downward descending, distal end connected to base-inner portion of spermathecae; spermathecae oval, apart from each other by about one-fourth their width; fertilisation ducts lamellar.

Diagnosis

The male of Phintella hongkan sp. nov. resembles that of P. arcuata Huang, Wang & Peng, 2015 in having similar habitus and palpal structure, but it differs in: 1) the carapace posteriorly has a pair of dark patches (Fig. 2 C) versus absent in P. arcuata ( Huang et al. 2015: fig. 1 A); 2) the cheliceral fang lacks terminal flap (Fig. 2 G) versus present in P. arcuata ( Huang et al. 2015: figs. 1 B and 3 C); 3) the posterior lobe is downward extended (Fig. 1 A) versus postero-retrolaterally in P. arcuata ( Huang et al. 2015: figs. 1 C and 3 A); 4) the bulb has antero-retrolaterally extended lamellar process (Fig. 1 A) versus retrolaterally in P. arcuata ( Huang et al. 2015: figs. 1 C and 3 A); 5) the retrolateral shoulder of bulb has an inverted V-shaped edge (Fig. 1 A) versus arc-shaped edge in P. arcuata ( Huang et al. 2015: figs. 1 C and 3 A). The female closely resembles that of P. pygmaea (Wesołowska, 1981) in having an almost identical epigyne, but it can be easily distinguished by the absence of the basal epigynal plate (Fig. 2 A) versus present in P. pygmaea ( Wang et al. 2023: fig. 25 A) and the presence of a pair of dark patches posteriorly on carapace (Fig. 2 E) versus absent in P. pygmaea ( Wang et al. 2023: fig. 25 E).

Etymology

The specific name is after Hongkan Waterfall, a famous scenic spot nears the type locality; noun (name) in apposition.

Distribution

Known only from the type locality in Hainan, China.
