[Crustacea • 2017] Kani maranjandun • A New Genus and New Species of A Fully Arboreal Crab (Decapoda: Brachyura: Gecarcinucidae) from the Western Ghats, India, with Notes on the Ecology of Arboreal Crabs



Kani maranjandun 
Kumar,  Raj & Ng, 2017


Abstract
A new genus and new species of tree crab is described from the Western Ghats biodiversity hotspot in Kerala, southern India. Kani maranjandun gen., n. sp., is substantially different from all congeners in a suite of characters, notably the diagnostic carapace and male abdominal structure, as well as the conspicuously elongated ambulatory legs. The species is wholly arboreal, living in tree-hollows or the canopy.
Keywords: freshwater crabs, Kerala, new taxa, systematics

Superfamily Gecarcinucoidea Rathbun, 1904 
Family Gecarcinucidae Rathbun, 1904

Kani n. gen. 

Etymology: The genus is named after the people of the Kanikkaran (also known as Kani) tribe in Kerala, who helped in the collection of tree crab from near their hamlet. India’s Agasthyamala Biosphere Reserve, southern Western Ghats is home to the largest population of this ancient Indian tribe. The gender of the genus name is neuter

  Kani maranjandu n. gen., n. sp. in its natural habitat.
Paratype male (40.5 × 30.0 mm) (DABFUK). Kerala, India. 

Kani maranjandu n. gen., n. sp. 

Etymology: The species name is derived from the Malayalam word mara for “tree” and njandu for “crab”. The name is used as a noun in apposition.

Ecology: Kani maranjandu n. gen., n. sp. is the first tree-climbing crab reported from India. Morphological features such as distinctly long legs with hooked dactyli are clearly arboreal adaptations. The type series was collected from the tree hollows of a Bedda nut tree, Terminalia bellirica (Gaertn.) Roxb. (Combretaceae).  ....

When approached by members of the Kani tribe, the crabs climb up the trunk of Cinnamomum verum, the tribesmen then cut a series of holes in trees to climb up after them.
