Material examined.

China: Yunnan: Xishuangbanna: Mengla County: Menglun Town : Menglun Nature Reserve : 1♂ 1♀, 48 km landmark in Nature Reserve , seasonal rainforest (21°58.704'N, 101°19.748'E, 1080 m), 12 August 2011, G. Zheng leg. ; 1♂ 1♀ (YHCLU0124-125), 55 km landmark in Nature Reserve , seasonal rainforest (21°57.953'N, 101°12.305'E, 780 m), 13 August 2011, G. Zheng leg.

Diagnosis.

Both sexes of P. pteronetoides are similar to those of P. viridula in having similar palps and epigynes but can be differentiated by the elongate-oval bulb in ventral view (Fig. 15B ) (vs. pyriform or triangular) and by the oval spermathecae that are ~ 2 × longer than wide (Fig. 16C, D ) (vs. claviform spermathecae that are ~ 3-4 × longer than wide).

Description.

See Deeleman-Reinhold (2001). Male palp as in Fig. 15A-E , epigyne as in Fig. 16A-D , habitus as in Fig. 16E-H .

Comments.

There is almost no difference between males from Xishuangbanna (Fig. 15A-E ) and the holotype from Thailand ( Deeleman-Reinhold 2001: 97, figs 5-7). However, some intraspecific variation is exhibited by females from the two localities, related to distance between the two copulatory openings. The copulatory openings are separated by ~ 1/4 of their diameter in material from Xishuangbanna (Fig. 16A-D ) but not separated in the paratype ( Deeleman-Reinhold 2001: 97, fig. 4).

Distribution.

Thailand (Prachuap Khiri Khan Province), China (Yunnan Province, new record). The present results extend the range of this species by ~ 1090 km to the northwest (Xishuangbanna) from the type locality (Prachuap Khiri Khan).
