New Records for Two Sergestids: Sergestes orientalis Hansen, 1919 and Sergia umitakae Hashizume and Omori, 1995 (Crustacea, Decapoda, Sergestidae)

This paper is on 2 holopelagic shrimps, Sergestes orientalis and Sergia umitakae. Sergestes orientalis is examined on the basis of the material of the International Indian Ocean Expedition (IIOE) for taxonomy and distribution. The species was found during the Anton Brunn, Diamantina, Discovery, Oshoro Maru, and Varuna cruises, and reported from the tropical Indian Ocean, the Indo-Australian Archipelago, the western tropical Pacific, and Hawaiian Islands. Two research vessels (Diamantina, Oshoro Maru) collected the material of S. orientalis from the Bay of Bengal located at GPS coordinates between 21°30´S, 110°00´E and 05°55´S, 95°04´E. This report of S. orientalis fills the gap in its distribution. We provide a brief description and illustrations based on the material collected from the Bay of Bengal. The other shrimp, Sergia umitakae, was originally described from the Indian Ocean off Sri Lanka and characterised by having many lenses bearing dermal photophores. The species is reported for the first time from near Java based on the collection sampled by the research vessels Anton Brunn, Argo, Conch, Discovery, Gascoyne, Koyo Maru, Oshoro Maru, Pioneer, and Varuna during the IIOE (1960-1965). Sergia umitakae is described and illustrated based on the Java specimens. Specimens examined here are preserved in the Marine Reference Collection and Resource Centre (MRC & RC), University of Karachi.
