A new species of cavernicolous crab from Coron Island, Palawan, the Philippines (Decapoda: Brachyura: Varunidae)

Pukaway Cave, an anchialine cave on Coron Island (Palawan Province, Philippines) is shown to harbour three distinct species of Orcovita Ng & Tomascik, 1994. Two of these have been previously described elsewhere (viz. O. angulata Ng, Guinot & Iliffe, 1996, and O. holthuisi Ng & Ng, 2009). A new species, O. tabiacoud, as well as the male of O. angulata, are described for the first time here. The presence of three different species of Orcovita in the same biotope is discussed.
