[Entomology • 2017] Coeliccia duytan • A New Species of Damselfly (Odonata: Platycnemididae) from the Central Highlands of Vietnam

Coeliccia duytan  Phan, 2017


Coeliccia duytan sp. nov. (holotype male, from Chu Mom Ray National Park, Kon Tum Province, the Central Highlands of Vietnam, deposited in zoological collection of Duy Tan University) is described based on both sexes. The new species is closely related to C. hayashii Phan & Kompier, 2016 by the extensive rectangular pruinosity on the synthorax but differs in lacking a pale antehumeral stripe, genital ligula with flagella pointed at tip and the shape of cerci.

Keywords: Odonata, Platycnemididae, Coeliccia duytan sp. nov., Vietnam

Etymology. This specific epithet is derived from my office Duy Tan University; duytan, a noun in apposition.

Habitat and Ecology. This is a shy species, usually perching ca. 20–30 cm high in dark forest underlain with decomposing leaf litter. It was found at streams (4–6m width) with large stones in pristine forest. At the type locality, this species occurs with two other congeners C. mientrung Kompier & Phan, 2017 and C. dydima (Selys, 1863) (new record for Vietnam, unpublished).
