Insulamon Palawanense is species of freshwater crab from the Philippines described in 2012.[1][2] They are 2.5–5.3 centimetres (1.0–2.1 in) wide and are a striking purple colour. The species was described by Hendrik Freitag of the Senckenberg Museum of Zoology in Dresden, Germany, having previously been included in a wider circumscription ofI. unicorn.[1] The species is endemic to the island of Palawan, where it has a wide distribution.[2] The striking iridescent purple coloration may help the crabs to recognise others of its species,[2] or may serve no purpose.[3]
