See Bousfield (1984).</p> <p>Remarks. With the transfer of T. limicola to Chelorchestia, this is the first record of this genus for the Western Pacific region. The five previously known species of Chelorchestia were confined to the Americas: C. darwinii (Müller, 1864) and C. forceps Smith &amp; Heard, 2001 found on the Atlantic side and C. colombiensis Valencia &amp; Giraldo, 2009, C. costaricana (Stebbing, 1906b) and C. vaggala (Bowman, 1977) on the Eastern Pacific side. Bousfield (1984) also suggested the occurrence of Chelorchestia from the Eastern Atlantic – Nigeria, although this material has never been described.</p> <p>Essentially Chelorchestia seems to have a Gondwanan distribution and with a consequently old origin, about 100 Ma. Despite the very scarce fossil record of the amphipods, Bousfield (1984) postulated a hypothesis for the evolution of the talitrids, which apparently evolved from a 5-dentate hyalid ancestor by the middle Cretaceous (110-90 Ma). The palustral group, including Chelorchestia and four other genera, would be one of the first to evolve as they are very water dependent. By the late Cretaceous (90-70 Ma) the diversification of the flowering plants and rhizophoroid mangrove swamps developed through the coastal tropics and provided suitable habitats for the explosion and colonization of the talitrids – initially in the mangroves and coastlines of the world and latter on invading the litter of the forest by the early Cenozoic time (60 Ma).</p> </div>	https://treatment.plazi.org/id/E31487F1B93EFF8D06D2FDF7FEFFDE8D	Public Domain	No known copyright restrictions apply.

The material was found on mangrove roots behind beach, or under the leaf litter from around crab holes at back of beach.</p> <p>Remarks. Chelorchestia limicola was described by Haswell (1880) within Talorchestia, but has never been redescribed. Despite the brief description of Haswell (1880), it was possible to identify this species based on the diagnostic male gnathopod 2. The type material is apparently lost (Lowry &amp; Stoddart 2003) and the designation of a neotype, based on material from Lizard Island, is herein proposed as the type locality was originally from Queensland. Chelorchestia currently includes five species: C. costaricana from mangrove swamps in Costa Rica (Stebbing 1906b); C. darwini from mangrove and estuarine areas of the Brazilian coast (Serejo 2004b); C. forceps from south-eastern coast of United States; C. colombiensis from Palma Island, off the Pacific coast of Colombia found on the littoral fringe zone associated to encrusting and filamentous algae (Valencia &amp; Giraldo, 2009), and C. vaggala from San Cristóbal Island (Galapagos Islands) found on litter of altitudes varying from 450 to 600 m (Bowman, 1977).</p> <p>Chelorchestia limicola is easily identified as a Chelorchestia as the male gnathopod 2 is chelate, the outer ramus of uropod 1 lacks setae and the species typically lives in mangroves as most species do. However, the general structure of male gnathopod 2 of C. limicola is different when compared with other species of the genus. Chelorchestia vaggala is the most different. In the original description a small male (9.4 mm) was described as having a subchelate male second gnathopod with transverse palm (Bowman 1977). However, ontogenetic variation in this appendage suggests that this gnathopod form could be a juvenile stage of a terminal chelate gnathopod (see Smith &amp; Heard 2001), although not yet documented for this species. Considering that the chelate gnathopod is a diagnostic feature for Chelorchestia it would important to collect more mature males of C. vaggala to confirm its generic status.</p> <p>Comparing C. limicola with the recently described C. colombiensis, both have gnathopod 2 propodus not elongated and the thumb-like process is bifid. However, the basis of male gnathopod 2 of C. limicola does not have tubercules on the anterior margin; the ischium is not lobate and the proximal hump on palm is also absent. Moreover, the dactylus of C. limicola has a better developed process. Compared with the other three Chelorchestia species (C. costaricana, C. darwinii and C. forceps), C. limicola has the male gnathopod 2 propodus about 1.4 x as long as broad (vs around 2 x as long as broad); and the propodus thumb-like process is thick and bifid, not much extended anteriorly (vs. slender, not bifid and very extended anteriorly, especially in terminal males).</p> <p>Distribution. Australia. Queensland: near Bowen (Haswell 1880); Mermaid Cove, Lizard Island (current study).</p></div> 	https://treatment.plazi.org/id/E31487F1B93EFF8806D2FAF1FEE9DD3D	Public Domain	No known copyright restrictions apply.

Oostegites 2–5 oval with few marginal setae.</p> <p>Remarks. Dana (1852, 1853) described T. spinipalma based on few and unclear illustrations. Later, this species was properly illustrated by J.L. Barnard (1960) based on material from Micronesia. Bousfield (1970) recorded T. spinipalma from Rennell Island making only few comments on the females, and no illustrations. The records of T. spinipalma for Australia has been always based on Stebbing´s (1906a) synonymy, where he stated that T. terraereginae described by Haswell (1880) for Queensland was a junior synonym of T. spinipalma. In fact, the syntype series of T. terraereginae was observed and proved to be a valid species. Therefore, this is a first record of T. spinipalma for Australia based on observed material. Diagnostic characters pointed out in Table 1 for T. spinipalma were observed and illustrated based on the Australian material, which confirms its identification. Morino &amp; Miyamoto (1988) redescribed T. spinipalma with material from Papua New Guinea and New Caledonia and compared it with the close species T. palawanensis Morino &amp; Miyamoto, 1988 from Palawan Island, Philippines. However, with the observation of the type series of T. terraereginae it became clear that T. palawanensis is a junior synonym of the former as will be discussed in details below. Differences between these species can be found in Table 1.</p> <p>Table 1.

Since the work of Stebbing (1906a) T. terraereginae has been considered as a junior synonym of T. spinipalma as the former species was poorly described and illustrated. Study of the syntype series of T. terraereginae deposited in the Australian Museum, revealed important diagnostic characters that clearly distinguished this species from T. spinipalma as indicated in Table 1, and showed that T. terraereginae is a senior synonym of T. palawanensis. Morino &amp; Miyamoto (1988) found some specimens of T. terraereginae (treated as T. palawanensis) at Thursday Island, Australia and pointed some variations between the population from Philippines and Australia. However, as these authors stated, these differences were all size related as observed with the T. terraereginae population herein described. An exception is the eye shape described as “more variable and some are much broader than deep” for the Thursday Island population (Morino &amp; Miyamoto 1988). This variation in the eye shape was not observed in the present material, they all have a subsquare shape and the dorsal and ventral margins are truncate.</p> <p>Distribution. Australia.
