Description
Summary:Encephaloides is a monotypic genus with only one species, E. armstrongi, now known to be widely distributed in both the Arabian Sea and Bay of Bengal. A large number of specimens of Encephaloides armstrongi were collected during commercial trawling operations on board two vessels FV Hu Yu-823 and Hu Yu-824 on Aug 1, 2004 from a depth of 120m depth off Shumal Bundar. Two specimens are now donated to and housed in Marine Reference Collection and Resource Centre, University of Karachi, the rest of the material is kept at the Marine Fisheries Department, Karachi. The specimens from Pakistan agree well with the original and latter descriptions. According to Griffin, the very small specimens, measuring 10mm carapace length have the branchial region meeting anteriorly only, and a small medial spine is visible on the cardiac and intestinal regions. However, in larger specimens the cardiac spine is still visible. The specimens are all collected from North-east Indian Ocean, almost all specimens were male.
