Diagnosis. Male of S. gollum Lin & Li , sp. nov. is similar to Raveniola montana Zonstein & Marusik, 2012 (the genus is allied to Sinopesa , distinguished only by the longer legs and developed scopulae) in having a similarly shaped E but can be distinguished by the terminus, which is directed opposite of the tarsus (vs. directed toward the tarsus in R. montana ), and S. gollum Lin & Li , sp. nov. has six eyes (vs. eight eyes in R. montana ).
