Kemp, however, also illustrated differences morphology male thoracic sternums, chelae, first gonopods and, accordingly, divided D. into subcategories which he called “high form” “low form”. The recent designation a lectotype for...

Abstract The present study reports the first zoogeographical record of squat lobster Munidopsis lauensis Baba and de Saint Laurent, 1992 from a cold-seep site in Krishna-Godavari Basin (Bay Bengal), Northern Indian Ocean. Molecular analysis partial mitochondrial gene coding for cytochrome C oxidase subunit I (COI mtDNA), 16S ribosomal RNA (16S rRNA) validated its identity. observation extends geographical distribution to Additionally, molecular barcodes (COI) were generated scobina Alcock,...

The identity of “Ptychognathus andamanica Alcock, 1900” originally described from Saddle Hill in North Andaman Island, India, is clarified. This species was synonymized with Ptychognathus riedelii (A. Milne-Edwards, 1868) based on the morphological characters female specimens by 1900. A re-examination sole remaining syntype (deposited Zoological Survey India collection and herein designated as lectotype) a fresh male specimen collected Islands revealed that P. andamanicus morphologically...
