New record of the swimming crab Charybdis (Archias) hongkongensis Shen, 1934 (Brachyura, Portunidae) from India

Abstract

Charybdis (Archias) hongkongensis Shen, 1934 was collected from the Indian coast of the Bay of Bengal and this is the first record from Indian waters. The distinct key characters of this species are: a relatively more produced last antero-lateral tooth, strongly convergent postero-lateral margins, and a smooth, rounded, reduced apex of the male first gonopod. This is the ninth member of Charybdis (Archias) Alcock, 1899 from Indian waters. The species is diagnosed and figured herein.
