Sidabalok (2019) in her analysis of the genus Cirolana identified several apomorphy supported clades. The larger clades have been given ‘group names’ such as the Cirolana ‘ parva group’ and the Cirolana ‘ pleonastica group’ (see Rodcharoen et al. 2016; Sidabalok &amp; Bruce 2017, 2018a). Cirolana swaraj sp. nov. belongs with a small group of, at present’, five species that includes the type species Cirolana cranchi Leach, 1818 .</p><p>The most recent detailed and comprehensive diagnoses to Cirolana remain those of Bruce (1986) and Brusca et al. (1995). More recently restrictive diagnoses to definable species groups within the genus have been given by Bruce (2004) for the Cirolana ‘ parva group’ and by Sidabalok &amp; Bruce (2018) for the Cirolana ‘ pleonastica group’.</p></div>	https://treatment.plazi.org/id/038BBF69FFE4EA30DFC5F964FF3BAADB	Public Domain	No known copyright restrictions apply.

Adult males (n=8) 6.5–8.8 mm (mean 7.7 mm); females (n=12) 6.9–8.9 mm (mean 7.9 mm).</p><p>Remarks: Males of Cirolana swaraj sp. nov., can be identified by the pereonite 1 dorsal anterior mid-region with convex dome with a finely wrinkled surface, a character unique to this species, and both males and females by pereonites 1–7 each with a single transverse impressed line and having 18, 18, 17 and 12 tubercles on pereonites 4−7 dorsal posterior margins respectively; pleonites 4 and 5 each with prominent median tubercle, and four and two tubercules on each side of pleonites 4 and 5 respectively; frontal lamina 2.2 times as longer than greatest width, slightly widening to the rounded anterior margin; pleotelson dorsal surface with double row of five sub-median tubercules, posterior lateral margins sinuate with a narrowly rounded apex is with six robust setae and plumose marginal setae extending well to the anterior; the uropodal exopod lateral margin has eight robust setae and a continuous row of plumose marginal setae.</p><p>Cirolana swaraj sp. nov., belongs with a small group of species, referred to as ‘Clade D’ by Sidabalok (2019). This clade comprises Cirolana browni Van Name, 1936, Cirolana cranchi Leach, 1818, Cirolana pustulosa Hale, 1925, Cirolana willeyi Stebbing, 1904, Cirolana harfordi (Lockington 1877) . The clade will likely be found to include other species that were not included in the analysis. One of the characters of this clade is that the pleotelson marginal setae extend well anterior to the robust setae, the uropod setation is usually dimorphic, with males having more abundant setae, pleonite 4 is not posteriorly extended, penial processes are lacking, and all species are to a greater or lesser degree nodular, though in the two cold-water species, the eastern Atlantic C. cranchi and the northern Pacific C. harfordi, the nodules are quite small. Of these five species C. browni, C. cranchii and C. harfordi are well out of range and lack the larger nodules and ornamentation (Bruce &amp; Ellis 1983; Bruce 1986, Brusca et al. 1995) of C. swaraj sp. nov,. Cirolana willeyi, a strongly nodular species with, in adult males, prominent nodules on the head and pereonite 1, is immediately distinguished by have a distinctly pentagonal frontal lamina, the uropod exopod with an acute apex and the endopod with a narrowly rounded apex (both rami are rounded in C. swaraj sp. nov.). Cirolana pustolosa has a rounded frontal lamina, but has strongly sinuate pleotelson lateral margins, with elongate and bluntly rounded uropodal rami that extend well beyond the pleotelson posterior margin.</p><p>Cirolana swaraj sp. nov. appears most similar to some of the figures given for the very poorly known C. fluviatilis Stebbing, 1902 (Barnard 1935; Chilton 1924, 1926; Pillai 1967; Sanil et al. 2009). It appears that most records of C. fluviatilis other than those from South Africa do not correspond with the South African species and are misidentifications. Barnard (1935, fig. 19) gave comparative figures of a syntype (‘cotype’) and of a specimen from East London, and of specimens from Travancore and Chilika Lake. C. swaraj sp. nov., is immediately distinguished by the males having a prominent dome on pereonite 1 and, in all cases, having the pleotelson longitudinal ridges consisting of a large anterior nodule and row of short acute nodules progressively decreasing in size posteriorly, while the uropodal endopod of C. swaraj sp.nov., is far more broadly rounded than that of South African C. fluviatilis . With regard to C. ‘ fluviatilis ’ from Travancore (Barnard 1935 fig. 1a), the uropod endopod shape is more similar to that of C. swaraj sp.nov., but is more posteriorly straight, and the pattern of nodules on the pleon and pleotelson for both species is different, with the Travancore nodules being smaller, lacking a dominant median nodule, and additionally, the pleotelson lateral margins are distinctly convex, with the telson having a broadly rounded pleotelson. None of the records of C. fluviatilis from South Africa and from India have been fully described, but all records other than those from South Africa are misidentifications and as such those records must be disregarded.</p><p>Although there is a strong superficial resemblance to several species of the Cirolana ‘ pleonastica group’, all these species can be ruled out by having the uropodal exopod with only three widely spaced small robust setae, and discontinuous slender setae, and the pleotelson marginal slender setae not extending anteriorly from the posterior row of robust setae.</p><p>Distribution. Known only from the type locality, South Andaman, Andaman Islands.</p><p>Etymology. The epithet is the Indian name of Havelock Island; noun in apposition.</p></div>	https://treatment.plazi.org/id/038BBF69FFE7EA38DFC5FB4DFBBEAA57	Public Domain	No known copyright restrictions apply.

This entire region is very poorly documented with regard to Cirolanidae, with the exception of Pakistan where there has been some documentation of intertidal taxa (e.g. Bruce &amp; Javed 1987; Javed &amp; Yasmeen 1995; Yasmeen 2005, 2008 inter alia). More recently Cirolanidae have been described from the Andaman Islands (Anil &amp; Jayaraj 2023 and references therein) and also from the western coasts of Thailand (Rodcharoen et al. 2016). The limited records of Cirolanidae suggest that any key to the species of the larger genera, which includes Cirolana, would be very premature given that a wealth of species remains to be discovered and described, notably from coral reef habitats and the faunistically rich continental shelf and slope. Premature species keys lead to misidentifications and then to the perpetuation of misapplied names. It is hoped that this key to the genera will expedite the further identification of Cirolanidae in the region.</p><p>1.
