Abstract:Trawls from the Bay of Bengal obtained material of a new species of the goneplacid crab, Carcinoplax mistio, the sixth species of the genus known from India. The new species superficially resembles C. purpurea Rathbun, 1914, and C. sinica Chen, 1984, from the western Pacific. Records of C. sinica from the Persian Gulf are also here referred to the new species. Carcinoplax mistio n. sp. differs from its closest congeners mainly in the form of the carapace, anterolateral armature, proportions of the ambulatory l… Show more

“…On 22 January 2023, a single specimen of goneplacid crab, C. haswelli was collected from the trawl bycatch landing of Veraval fishing harbour (20°50 ′ N and 70°28 ′ E), Gujarat, Northwest coast of India (Figure 1). The specimen was caught through the demersal trawler targeted for the commercial group of crustaceans and the trawler was operated at an actual depth of 30-150 m. The collected specimen was identified as C. haswelli (Figure 2) by referring to taxonomic literatures Ng and Mitra, 2019;Ng and Castro, 2020). The morphometric measurements of the specimen was made using the Vernier caliper with an accuracy of 0.1 mm and the photographs of the crab were captured using the Nikon D-5300 camera.…”

“…Further, the reddish carapace colour pattern in C. sinica makes it to differ from the closest species C. purpurea (Guinot, 1989). Ng and Mitra (2019) recently described a new species, Carcinoplax mistio from the Bay of Bengal region. They stated that C. mistio superficially looks like C. sinica, particularly the transverse-shaped carapace and 2nd prominent front-lateral tooth spiniform and mildly curved; in G1 of C. sinica two-third of distal part is straight and the tip is round and short (Figure 7), on the other hand in C. mistio two-third of distal part is curved and the tip is elongated; this was observed from the holotype male (29.2 × 19.0 mm, ZSI Reg.…”
A single male specimen of Goneplacid crab, Carcinoplax haswelli (Miers, 1884) is recorded for the first time from the Indian Ocean. The crab specimen was collected from the trawl bycatch landing of the commercial demersal trawler operated between 30 and 150 m depth along the Gujarat coastal region, Northwest coast of India. This C. haswelli is previously recorded from northern Australia and Taiwan to South China Sea. Until now, C. haswelli is not observed or recorded from the Indian Ocean. In the present study, detailed information regarding the taxonomic identification and previous distribution of the goneplacid crab, C. haswelli is described.

“…Nauplius, 29: e2021034 introduction The deep-water brachyuran fauna of India is moderately diverse and was substantially documented during the colonial era (Wood-Mason, 1885;1888;Wood-Mason and Alcock, 1891;1895;1896;1898;1899a;1899b;1900a;1900b;1901;Alcock and Anderson, 1894;1899;McArdle, 1900;1901;MacGilchrist, 1905;Lloyd, 1907;Kemp and Sewell, 1912). In comparison, the recently published literature revealed few reports on the deep-water Brachyura based on the collections of the deep-sea by-catch species along the peninsular coasts of India (Kumar et al, 2013;Ng and Kumar, 2015;2016;Mendoza and Devi, 2017;Ng et al, 2017a;2018a;2018b;Ng and Mitra, 2019;Mendoza et al, 2020).…”
Section: Rare Deep-water Crabs From Indiamentioning
Deep-water brachyuran crabs collected from the Indian Exclusive Economic Zone by the Fishery Oceanographic Research Vessel "Sagar Sampada" in the southeastern Arabian Sea (50 m depth), southwestern Bay of Bengal (307 m depth), and in the vicinity of the Andaman and Nicobar Archipelagos (271-535 m depth) were studied. They are referred to Sphaerodromia kendalli (Alcock and Anderson, 1894) and Sphaerodromia nux Alcock, 1900 (family Dromiidae), Intesius brevipes sp. nov. (family Mathildellidae), Tunepugettia corbariae B.Y. Lee, Richer de Forges and P.K.L. Ng, 2019 (family Epialtidae), Cyrtomaia suhmii Miers, 1885 (family Inachidae), Chaceon alcocki Ghosh and Manning, 1993 (family Geryonidae), and Sphenomerides trapezioides (Wood-Mason, 1891) (family Trapeziidae). Sphaerodromia nux and T.corbariae are new records from Indian waters. The first male specimen of C. alcocki is reported, with a description of the male first gonopod. Intesius brevipes sp. nov. is the fifth species of the genus, differing from the four known congeners in the form and setation of the carapace, distinctly curved and granular anterolateral margins, and shorter pereopods with much slender merus and carpus articles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
