The species name is derived from the type locality; noun in apposition. Diagnosis. This new species resembles O. longituba Wang, Zhang & Zhang, 2012 in having a similar-shaped embolus, but can be recognized by: 1) the palmate-shaped retrolateral tibial apophysis (vs rectangular, cf. Fig. 47B and fig. 5F in Wang et al. [2012] ), 2) the closely situated copulatory openings (vs separated by about one spermatheca diameter, cf. Fig. 47E and fig. 5H in Wang et al. [2012] ), and 3) distinctly separated spermathecae (vs close to each other, cf. Fig. 47F and fig. 5G in Wang et al. [2012] ). Description.
