The species name is derived from the vernacular Malayalam word “Keralam” denoting the southwestern Indian state of Kerala; used as noun in apposition.</p> <p>Remarks. Poore &amp; Collins (2009) commented that Calocaris (Calastacus) hirsutimana Boesch &amp; Smalley, 1972, Axiopsis (Axiopsis) caespitosa Squires, 1979 referred to Acanthaxius by Sakai and de Saint Laurent (1989), and Acanthaxius polychaetes Sakai, 1994, differed from the typical Acanthaxius in the presence of male pleopod 1, absence of prominent supraocular spine, comparatively more compact propodus on the major cheliped with few lateral spines, and presence of prominent lateral spine on the telson; additionally, Acanthaxius spinulicauda (Rathbun, 1902) reportedly differed from the type species A. pilocheira K. Sakai, 1987 in possessing a less spinose carapace. They further suggested the creation of new genera to accommodate these species.</p> <p>Sakai (2011) retained A. spinosissima in Acanthaxius due to the absence of male pleopod 1. He erected a new genus, Guyanacaris, for C. hirsutimana (as type species) and A. caespitosa, owing to an elongate, forwardly directed antennal scaphocerite and the presence of uniramous, bisegmented male pleopod 1. He erected another genus, Bruceaxius K. Sakai, 2011, for A. polychaetes (as type species), owing to the presence of uniramous, bisegmented male pleopod 1, with a digitiform distal segment, carapace with anterolateral spine and postcervical carina, P1 chela with unarmed dorsal margin and thickly setose lateral surfaces, fingers of larger cheliped shorter than palm, those of smaller cheliped distinctly longer than palm, and pleonal 1–5 tergites and pleura separated by longitudinal carina. Moreover, he transferred A. spinulicauda to another genus Leonardsaxius K. Sakai, 2011, owing to smooth submedian and lateral gastric carinae on the carapace.</p> <p>Dworschak (2013) and Dworschak and Poore (2018) recognized Guyanacaris for G. hirsutimana and G. caespitosa. Moreover, Dworschak and Poore (2018) considered Sakai’s (2011) definition of Guyanacaris to be weak. Sakai (2015) described a second species of Bruceaxius, B. thailandensis. Poore (2020) commented that A. polychaetes K. Sakai, 1994 and A. spinosissima (Rathbun, 1906) probably belonged to Guyanacaris owing to the presence of multi-spinate lateral gastric carinae converging anteriorly on small supraocular spines, and a mesial spine at the base of scaphocerite. If A. polychaetes, type species of Bruceaxius, is considered to be a Guyanacaris, then Bruceaxius should be considered to be a synonym of Guyanacaris. With regards to B. thailandensis, it was noted that the line illustration of the antennal peduncle (Sakai 2015: Fig. 3A) did not clearly indicate the presence of a mesial spine at the base of scaphocerite. In view of this, it is herein considered that B. thailandensis differs from the typical Guyanacaris in the absence of a mesial spine at the base of scaphocerite, major P1 carpus, propodus and dactylus with tuberculate upper margins, male pleopod 2 with tri-segmented appendix masculina (Table 2). It is therefore suggested that this species may be tentatively retained in Bruceaxius.</p> <p>......continued on the next page</p> <p>......continued on the next page</p> <p>......continued on the next page</p> <p>In view of this, Guyanacaris K. Sakai, 2011, is presently considered to represent 5 species— G. caespitosa (Squires, 1979), G. hirsutimana (Boesch &amp; Smalley, 1972), G. keralam sp. nov., G. polychaetes (K. Sakai, 1994) and G. spinosissima (Rathbun, 1906), with known geographical distribution in the Atlantic and Indo-Pacific Oceans. This genus differs from Acanthaxius Sakai &amp; de Saint Laurent, 1989, in having short supraocular spine, the presence of post-cervical carina on the carapace, dentate margins of pleura 1–2, angular to almost straight posterior margins of pleura 3–5, scaphocerite with mesial spine at base, and the presence of male pleopod 1 (Sakai 2011; Poore 2020; present study). Morphological comparisons among the species of Guyanacaris and Bruceaxius are provided in Table 2.</p> <p>Distribution.

Ghost shrimps of the genus Paragourretia K. Sakai, 2004 resemble those of the genus Gourretia de Saint Laurent, 1973, but clearly differ from the latter in the absence of teeth on the occlusal margin of the minor cheliped fingers, tapering lower proximal margin of the major cheliped carpus, the presence of marginal notch and dorsal plate on the uropodal exopod, and the mesial position of the appendices interna and masculina on the endopod of the male pleopod 2 (Poore et al. 2019).Recently, Sakai (2017b) described a new genus and species Tuerkaygourretia galathea from one female and two males collected from the southwest Bay of Bengal off Tranquebar, India, two females from the northwest Bay of Bengal and one male off Singapore. However, Poore et al. (2019) opined that the illustrations of the chelipeds and the male pleopods indeed represented separate species from hitherto-known genera Gourretia and Paragourretia, which were confounded into a single morphological description, and therefore resulted in synonymizing Tuerkaygourretia with Paragourretia. According to Poore et al. (2019), the holotype was depicted only in figures 4A–C, E, F and 5A–C, E, G (Sakai 2017), and were used to compare the present material.</p> <p>In view of the above, the genus Paragourretia is now represented by eight extant species namely Paragourretia aungtonyae (K. Sakai, 2002), P. biffari (Blanco Rambla &amp; Liñero Arana, 1994), P. coolibah (Poore &amp; Griffin, 1979), P. crosnieri (Ngoc-Ho, 1991), P. galathea (K. Sakai, 2017b), P. laevidactyla (WL Liu &amp; RY Liu, 2010), P. phuketensis (K. Sakai, 2002) and P. portsudanensis (K. Sakai, 2005), with known circumtropical distribution. The ambiguous description of the type specimens of P. galathea (deposited in the Zoological Museum, University of Copenhagen) necessitated a redescription.</p> <p>The present specimens from the Arabian Sea were compared carefully with the eight known species about the relative lengths of the rostrum, ocular lobe and antennular peduncle, the armature of the third maxilliped merus, and the shape and armature of the telson. They were identified as P. galathea in spite of the following two differences from the holotype from the Bay of Bengal. 1) The terminal antennular article in the present specimens is slightly longer than the penultimate article [vs. terminal article is slightly shorter than the penultimate article in the holotype], but this character may be delicate, with possible individual or developmental variation; 2) A distomedian spine is present on the telson in the present specimens [vs. telson is unarmed in the holotype], but the spine is small, semi-transparent and partly disguised under the marginal hairs, with unavoidable omission. This problem on such differences may be settled with examination of the additional topographical specimens.</p> <p>Distribution. Bay of Bengal, off Tranquebar (11.10°N, 80.08°E) at 94 m, 20.62°N, 87.55°E at 50 m depth (Sakai 2017b); Arabian Sea, off Quilon at 100 m, off Panaji at 105 m.</p></div> 	http://treatment.plazi.org/id/03FF87B3FFB84B47FF54A80D869DC5DF	Public Domain	No known copyright restrictions apply.
