            </p>
            <p> Remarks.  Sphaerodromia nux was originally described from supposedly juvenile specimens (1 male of undetermined size, 1 female 10 × 11 mm) from the Gulf of Martaban off Myanmar at 129 m depth (Alcock, 1900a). The original description by Alcock (1900a) described only the carapace, and a subsequent monograph by Alcock (1901) provided a short description of the third maxilliped, chelipeds, and the vestigial male pleopods on pleonal somites 3–5 supplemented with a line illustration of the dorsal habitus (Alcock, 1901: fig. 19). Lewinsohn (1984) redescribed this species from adult specimens from Madagascar, and reported differences from the type specimen in the absence of a gap between the anterior margin of the third maxillipeds and the buccal cavern. McLay(1991)provided a detailed comparison between  S. nux and  Sphaerodromia ducoussoi McLay, 1991 , and supplemented with a table comparing the diagnostic morphological characters of all  Sphaerodromia species. Crosnier (1994) commented that  S. nux possessed well-developed podobranchs on the cheliped and pereopod 2, and vestigial bud-like podobranchs on pereopod 3. McLay (2001) amended Lewinsohn’s redescription and added morphological details of female specimens from the Philippines. A systematic revision of the family  Dromiidae by Guinot and Tavares (2003) included illustrations of the vestigial male pleopods, P5 coxa and G2. </p>
            <p>The present specimen agrees with the updated description by McLay (2001), except for the presence of lines of compressed granules on the P2–P3 meri (Fig. 4F–G) and a relatively higher dactylus length/ propodus length of 0.90 for P2–P3. The present observation is a new record in Indian waters.</p>
            <p>Distribution. Gulf of Martaban at 129 m depth (Alcock, 1900a; 1901), Madagascar (Guinot and Tavares, 2003), and Andaman Sea, India at 290 m depth (present study).</p>

            <p> Remarks. Specimens from the genus  Intesius Guinot and Richer de Forges, 1981 are extremely rare, with only 18 specimens (including the present study). The genus is characterized by a squarish carapace with less prominent anterolateral teeth, male pleon with strongly ankylosed somites 3–5 and a mobile sixth somite (Guinot and Richer de Forges, 1981a; Davie, 1998; Crosnier and Ng, 2004). Hitherto known only from the Western Pacific region (eastern Australia, New Caledonia, Norfolk Ridge, Philippines, French Polynesia, and Mariana Islands), the present observation is the first record of this genus from the Indian Ocean region.  Intesius brevipes sp. nov. differs from the existing congeners in: </p>
            <p> (1) sub-hexagonal carapace, CW/CL ratio 1.22 (Fig. 5A) (vs. quadrangular in  I. crosnieri,CW /CL ratio1.17 (Davie, 1998: figs. 1A, 2A) and  I. lucius, CW /CL ratio 1.15–1.17 (Crosnier and Ng, 2004: figs. 3B, 7); subcircular in  I. pilosus, CW /CL ratio 1.07–1.20 (Davie, 1998: figs. 1B, 2B); rectangular in  I. richeri, CW /CL ratio 1.26 (Crosnier and Ng, 2004: figs. 2, 3A)); </p>
            <p> (2) relatively less dense short setation on carapace that does not conceal the edges (Fig. 5A, B), similar to  I. lucius (Crosnier and Ng, 2004: figs. 3B, 7) (vs. dense setation in  I. crosnieri (Davie, 1998: figs. 1A, 2A),  I. pilosus (Davie, 1998: figs. 1B, 2B), and  I. richeri (Crosnier and Ng, 2004: figs. 2, 3A)); </p>
            <p> (3) distinctly projecting, bilobed frontal margin separated from the supraorbital margin by a distinct notch (Fig. 5A–C) (vs. very distinctly projecting, strongly bilobed frontal margin separated from the supraorbital margin by a wider notch in  I. pilosus (Guinot and Richer de Forges, 1981a:pl.7, fig.1,1a; Davie, 1998: figs.1B, 2B); less distinctly projecting, weakly bilobed frontal margin separated from the supraorbital margin by a narrow notch in  I. crosnieri (Davie, 1998: figs. 1A, 2A),  I. lucius (Crosnier and Ng, 2004: figs. 3B), and  I. richeri (Crosnier and Ng, 2004: fig. 3A)); </p>
            <p> (4) slightly elevated inner supraorbital lobe (Fig. 5A–C) similar to  I. pilosus (Davie, 1998: fig. 2B) (vs. indiscernible inner supraorbital lobe in the remaining species (Davie, 1998: fig. 2A; Crosnier and Ng, 2004: fig. 3A–B)); </p>
            <p> (5) distinctly curved anterolateral margins (Fig. 5A–C) (vs. moderately curved in its first part and then runs sub-parallel to longitudinal axis in  I. pilosus (Guinot and Richer de Forges, 1981a: pl. 7, fig. 1, 1a; Davie, 1998: figs. 1B, 2B); gently convex in  I. lucius (Crosnier and Ng, 2004: figs. 3B, 7); gently convex in its first part and then runs sub-parallel to longitudinal axis in  I. crosnieri (Davie, 1998: figs. 1A, 2A) and  I. richeri (Crosnier and Ng, 2004: figs. 2, 3A)); </p>
            <p> (6) more salient anterolateral teeth of carapace, particularly second and third teeth, bearing distinct granules (Fig. 5A–C), similar to  I. pilosus (Davie, 1998: figs. 1B, 2B) (vs. moderately salient teeth bearing moderately large granules in  I. crosnieri (Davie, 1998: figs. 1A, 2A) and  I. richeri (Crosnier and Ng, 2004: figs. 2, 3A); less developed teeth bearing short granules in  I. lucius (Crosnier and Ng, 2004: figs. 2, 3A)); </p>

            <p> (8) pereopods 2–5 bearing relatively short setae (Fig. 5A), similar to  I. lucius (Crosnier and Ng, 2004: fig. 7) and  I. richeri (Crosnier and Ng, 2004: fig. 2) (vs. long dense setae in  I. crosnieri (Davie, 1998: fig. 1A) and  I. pilosus (Davie, 1998: fig. 1B)); </p>
            <p>(9) relatively shorter P4–5 (pereopod length/ CL ratio 1.83 for P4, 1.49 for P5) with much more slender pereopod meri and carpi (length/width ratio 5.02 and 2.10 for P4, 4.73 and 1.96 for P5) (vs. longer P4–5 (pereopod length/ CL ratio 1.99–2.20 for P4, 1.78–1.97 for P5) with less slender meri (length/width ratio 3.88–4.48 for P4, 3.55–4.35 for P5) and carpi (length/width ratio 1.87–2.06 for P4, 1.48–1.83 for P5) in the remaining congeners).</p>
            <p>Etymology. The species name is derived from the combination of Latin terms “brevis” and “pede” alluding to the relatively shorter P4–P5. Gender is masculine.</p>

            <p> Remarks.  Tunepugettia corbariae was originally described from a male (31.4 × 21.2 mm) collected from Ainto Bay, Papua New Guinea at 430–620 m during the MADEEP Expedition (Lee et al., 2019). </p>
            <p>The present female specimen largely agrees with the original description, with exception of a relatively narrow carapace, PCL/CW ratio 1.29 (vs. Papuan female specimens, PCL/CW ratio 1.45–1.67 (Lee et al., 2019 )) and slightly less prominent protuberances on the carapace (Fig. 6A–C). The above differences in the present specimen as compared to the Papuan material could be attributed to the comparatively smaller size of the present material. The present observation is a new record in Indian waters.</p>

            <p> Remarks.  Cyrtomaia suhmii was originally described from a damaged male specimen (25 × 28mm) collected from the South China Sea, Indonesia at 915 m depth during the HMS Challenger Expedition (Miers, 1886). Doflein (1904) recognized two subspecies from the “Valdivia” collections in the Nicobar Islands, Indonesia (  C. suhmi typica ) and the Western Indian Ocean (  C. suhmi platyceros ) based on the differences in the form of carapace, rostrum, female pleon as well as the carapace ornamentation and texture. Bouvier (1915) recognized a separate subspecies from Japan,  C. suhmi curviceros based on arched pseudorostral and gastric spines, and poorly developed branchial spines. Serène and Lohavanijaya (1973) provided a key to the species and subspecies of the genus  Cyrtomaia including these subspecies. Griffin (1974) reported this species from the Andaman Sea off Thailand, along with morphological differences from the holotype with respect to the armature of the carapace and the basal antennal article. He also elaborated upon its synonymy and morphological relationships with congeners. Griffin and Brown (1976) reported a large female from Australian waters having long protogastric spines, one supraorbital spine and one mesogastric spine. Sakai (1976) elevated  C. suhmi curviceros to a distinct species. Guinot and Richer de Forges (1982) redescribed the holotype, attempted to resolve the taxonomic status of several of its subspecies, and compared other published descriptions with the holotype. They also elevated  C. suhmi typica to a distinct species,  C. gaillardi . Guinot and Richer de Forges (1985) reported morphological similarities of specimens collected during the MUSORSTOM I and II expeditions in the Philippines to both  C. suhmi and  C. curviceros and emphasized upon reviewing the identity of  C. curviceros . Griffin and Tranter (1986a) suggested that  C. suhmi curviceros is an adult stage of  C. suhmi and synonymized it with the latter. Griffin and Tranter (1986b) reported specimens from Australian waters and the Straits of Malacca having a large adult size, smooth carapace, and a short eyestalk. Richer de Forges and Guinot (1990) established a new species,  Cyrtomaia griffini , based on the material collected off the eastern coast of Australia, also including previously published reports (Griffin and Brown, 1976; Griffin and Tranter, 1986a; 1986b). Promdam (2011) reported this species in the Andaman Sea off Thailand and corroborated  C. curviceros to be a synonym of  C. suhmii on the basis of both adult and juveniles resembling these taxa, respectively. </p>
            <p>The present specimen (Fig. 7A, B, E) largely agrees with the original description by Miers (1886), the holotype specimen (see Guinot and Richer de Forges, 1982: figs.11A–B, 23B; Richer de Forges and Guinot, 1988: fig.2B,C), the Philippine specimens (see Guinot and Richer de Forges, 1985: figs. 11B, 12, 14A), line diagram of G1of male specimen from Tasman Sea (see Griffin and Tranter, 1986a: fig. 9e–g), the Western Australia specimen (Griffin and Tranter, 1986b: figs. 1, 2), and the Thailand specimen (see Promdam, 2011: figs. 1, 2D). However, it differs from the southeastern Arabian Sea specimens in Alcock’s report, in the presence of spine on the “last abdominal tergum” (Fig. 7D) (vs. smooth tergum in the latter specimens in Alcock’s report).</p>
            <p>Distribution. Indonesia at 915 m depth (Miers, 1886), Japan, Taiwan, Andaman Sea off Thailand at 502–512 m (Griffin, 1974) and southeastern Bay of Bengal at 271 m (present study).</p>

            </p>
            <p> Remarks. Alcock (1899a) erroneously reported a female geryonid (110.5 × 126.5 mm) from off Travancore (Kerala) coast at 410–520 m as  Geryon affinis . Ghosh and Manning’s re-examination of this specimen(1993)resulted in the establishment of a new species,  Chaceon alcocki , characterized by short frontal and anterolateral spines, the absence of distal spines dorsally on the P2–P5 meri, and laterally compressed pereopod dactyli. Jose et al. (2019) reported another female specimen (146 × 156 mm) collected from a commercial trawl landing along Kerala coast, and was reportedly caught at 260–300 m depth. </p>
            <p> The present specimen is the first male and the largest specimen reported for this species. The G1 is stout, curved, tapering distally; inner margin is covered with a row of short setae along proximal half, distal quarter with a short spinulose patch terminating sub-distally; outer margin with spinulose patch on distal one-third terminating sub-distally, followed by a small patch of long setae appearing like a spinose projection (Fig. 8J). G2 shorter than G 1 in length,slender, tapering distally, with spinose process subdistally on inner margin (Fig. 8J). Among the closely related congeners, published descriptions of only two species,  Chaceon macphersoni Manning and Holthuis, 1988 and  Chaceon goreni Galil and Manning, 2001 were supplemented with illustrations of the gonopods.  Chaceon alcocki differs from  C. macphersoni and  C. goreni in the presence of setae on both inner and outer margins (vs. row of setae on inner margin in  C. goreni (see Galil and Manning, 2001: fig. 3C–E); absence of setae on either margin in  C. macphersoni (see Manning and Holthuis, 1988: fig. 4G, H)). </p>
            <p>Distribution. Known only from the southeastern Arabian Sea off Kerala at 50–520 m depths (Ghosh and Manning, 1993; Jose et al., 2019; present study).</p>
