Abstract
AbstractSeven species of chirostyloid and galatheoid crustaceans, including three new species, are reported from the eastern Arabian Sea and Bay of Bengal, India, based on material from depths ranging from 32–1420 metres.Trapezionida samudrikasp. nov. appears close toT. munin(Komai, 2011), but is distinguished by the shape of the carapace and fourth thoracic sternite, the armature of the third maxilliped merus, the length and armature of the cheliped, and the armature of the ambulatory legs.Paramunida travancoricasp. nov. differs from its closest speciesP. bineeshiMacpherson, Chan, Kumar & Rodriguez-Flores, 2020,P. mozambicaCabezas, Macpherson & Machordom, 2010, andP. stichasMacpherson, 1993 in the morphology of the carapace and antennular and antennal peduncles.Munidopsis bhavasagarasp. nov. is similar toM. dentifalxOsawa, Lin & Chan, 2007, but distinguishable by the absence of a pair of elevated, short ridges on the epigastric carapace region and the proportionally shorter chelipeds and ambulatory legs. The present material ofMunidopsis unguiferaAlcock & Anderson, 1894 represents only the third record of the species in India and a detailed description and illustrations are provided to supplement the previous descriptions. The remaining three species,Eumunida multispinaKomai, Chakraborty, Paramasivam & Gidda, 2019,Munidopsis scobinaAlcock, 1894, andM. stylirostrisWood-Mason in Wood-Mason & Alcock, 1891, are recorded from additional localities within their known geographic regions.
