The male of  O. limushanresembles  O. jianfenglingin having similar median plate, but the male can be distinguished from it by: 1) shorter and thinner embolus; 2) hilt-like tegular apophysis; 3) thinner RTA; 4) smaller FA. This new species also resembles  O. florifera  sp. nov.in having a similar RTA, but can be separated from the latter by: 1) thicker and straight copulatory ducts, 2) broader median plate, 3) thinner RTA, and 4) no body stripes.  © Zoological Systematics, 40(4): 436–450  Figs 38–45.  Otacilia limushanFu, Zhang & Zhu, 2010. 38.

Copulatory openings small, situated medially on epigyne, located in the shallow concavities anteriorly ( Figs 36, 44, 50). Vulva anteriorly with a pair of large, transparent kidney-shaped bursae, posteriorly with a pair of spermathecae connecting with lightly curved copulatory duct, glandular appendage much shorter than fertilization duct. Distribution. China( Hainan). Note.  Otacilia limushanwas originally described by Fu, Zhang & Zhu (2010) on the basis of a female holotypecollected from Mt. Limu, Hainan Province, China. While examining the  Otaciliaspecimens collected from Mt. Limu in 2015, we easily identified the female as  O. limushanaccording to the original description, and considered that the male specimen also belongs to the same species because the habitus and the marking are very similar to those of the female. Therefore the male  O. limushanis reported for the first time. 3359630313 2007-08-18 Feng Zhang China Qiongzhong County 19.3 Mt.
