Geothelphusa cilan • Description of A New Montane Freshwater Crab (Crustacea: Potamidae) from northern Taiwan 
A new freshwater crab is described from a montane area in northern Taiwan based on morphological characters and molecular evidence. Geothelphusa cilan sp. nov., from the Cilan Forest, situated on the boundary of Hsinchu and Yilan (= Ilan) counties, is close to G. monticola Shy, Ng & Yu, 1994, and G. takuan Shy, Ng & Yu, 1994, but can be distinguished by its male first gonopod (G1) and the ratio of thoracic sternites. Molecular evidence from mitochondrial cytochrome oxidase subunit I (COI) also supports the identity of the new species.
The specimens were collected from the headstream of Danshuei River (Fig. 2H) near the boundary of Hsinchu and Yilan counties, near Yuanyang Lake Nature Reserve, with an altitude about 2000 m. The mean monthly water temperatures were 10.3–14.6°C during April to December, 2012 (mean 12.6°C) for the adjacent Yuanyang Lake, with the same drainage…
