Crustacea Leucosiidae systematics new genus Chilika Lake India

Abstract

The identity of Philyra alcocki Kemp, 1915 (Leucosiidae), a species described from Chilika Lake, India is clarified. The redescription of lectotype male and examination of fresh material collected from Chilika Lake, Odisha state of India revealed that P. alcocki is significantly different morphologically from members of Philyra senso stricto and other allied genera in possessing two tuberculated rows on the branchial region of carapace, and a well-developed tubercle on male thoracic sternite 5 on either side of the sternopleonal cavity. Therefore, a new genus Alcolyra n. gen. is established herewith for the species.
