D477D357D228A5347E93C5EFFBAF0698.taxon	etymology	Etymology A. chacei sp. nov. is named in honor of Fenner A. Chace, Jr (1908 – 2004) as an acknowledgement to his posthumous cooperation with us on the study of Atya - like shrimps of the Indo-Pacific region and for being the first to suggest that the Atyoida from Palau may belong to a distinct species.

D477D357D228A5347E93C5EFFBAF0698.taxon	discussion	Remarks Atyoida chacei sp. nov. resembles A. pilipes and A. tahitensis (Table 3) by its short, unarmed, bent rostrum, as well as by the proportions between the joints of pereiopods and the presence of ortmannioid and atyid chelae. The absence of caridinoid chelae in males or in females in these three species distinguishes them from A. serrata (Bate, 1888) and A. bisulcata Randall, 1840. Indeed, in these two species, the chelae are trimorphic: atyoid, caridinoid, and ortmannioid (see [44]). Due to their high morphological variability, finding diagnostic characters to separate A. chacei sp. nov. from A. pilipes or A. tahitensis turned out to be a difficult task (see Table 3), so much so that they could be considered to be cryptic species, as they can only be distinguished by the following characters: - Frequently, presence of one or more teeth on the ventral margin of the rostrum, vs. always 0 in A. pilipes and A. tahitensis. This character was already highlighted by Chace (1983): “ Of 613 specimens with complete rostra from the Palau Islands, 270 have no ventral rostral teeth, 240 have 1, 97 have 2, 5 have 3, and 1 has 4 ”; - Two – eight pairs of dorsal spinules, often not in pairs for A. chacei sp. nov. (vs. one – five pairs of dorsal spinules, often not in pairs for A. pilipes, vs. from two to four pairs of dorsal spinules, often in pairs for A. tahitensis); - Posterior margin rounded with from 8 to 11 plumose intermediate setae distinctly longer than lateral ones (vs. 4 to 9 plumose intermediate setae distinctly longer than lateral ones for A. pilipes, vs. with 6 to 10 plumose intermediate setae distinctly longer than lateral ones for A. tahitensis); - By the size of undeveloped eggs (0.51 – 0.52 mm × 0.29 – 0.31 mm (vs. 0.47 – 0.60 mm × 0.31 – 0.39 mm for A. pilipes, vs. 0.55 – 0.70 mm × 0.29 – 0.54 mm for A. tahitensis )). Nevertheless, following an integrative taxonomy framework, their genetic distinctiveness (16 S p-distances: 9 – 15 %) coupled with their discrete geographical distribution provides enough evidence to distinguish the two species as distinct taxa, as it was the case for other species of freshwater shrimps (e. g., [47 – 49]).	en	Mazancourt, Valentin de, Marquet, Gérard, Keith, Philippe (2024): An Integrative Taxonomic Revision of the Freshwater Atyid Shrimps (Crustacea: Decapoda: Caridea) of Micronesia.

D477D357D224A5337E93C448FCAE0300.taxon	discussion	Remarks Based on the form of the rostrum, the high pre-anal carina, the large number of uropodal teeth, and the shape of the telson, this new species belongs to the C. weberi species group. In this group, it is most similar to C. parvirostris by its short curved-down rostrum and slender P 2 carpus: 5.6 – 6.5 (vs. 6.0 – 7.4). However, it could be easily separated from C. parvirostris by lower numbers of dorsal and ventral teeth on the rostrum, respectively, 4 – 6 (vs. 8 – 10) and 0 – 1 (vs. 2). This new species is also similar to C. keiensis by its rostrum (lower numbers of dorsal and ventral teeth on the rostrum, respectively, 4 – 6 (vs. 2 – 13) and 0 – 1 (vs. 1 – 2 )) and its relatively long stylocerite reaching to 0.90 times the length of the basal segment of antennular peduncle (vs. 0.92), but it could be easily distinguished by its longer P 2 carpus 5.6 – 6.5 (vs. 3.5 – 4.5), and the size of the eggs 0.43 – 0.50 mm × 0.25 – 0.29 mm (vs. 0.39 – 0.42 mm × 0.24 – 0.25 mm).	en	Mazancourt, Valentin de, Marquet, Gérard, Keith, Philippe (2024): An Integrative Taxonomic Revision of the Freshwater Atyid Shrimps (Crustacea: Decapoda: Caridea) of Micronesia.

D477D357D222A52E7E93C0D9FADC0037.taxon	discussion	Remarks Our specimens agree well with those described from Bohol Island (Philippines) by Cai et al. [50] in relation to their long stylocerite, their stout first pereiopod, their short fingers, their third to fifth pereiopods ending in two claws, and their egg size. The rostrum in our specimens seems shorter: reaching the middle of the third segment of antennular peduncle (vs. reaching slightly beyond end of antennular peduncle) and its pterygostomian margin is rounded (vs. pterygostomian margin subrectangular), but we consider these differences to be within intra-specific variability. This species is closely related to C. buehleri and C. gueryi, both recently re-described by de Mazancourt et al. [43], but they are clearly separated in our molecular analyses and they can be distinguished by its P 1 chela 1.3 – 1.6 times as long as wide (vs. 2.2 – 2.3 for C. buehleri and 1.9 – 2.4 for C. gueryi), and by its P 5 dactylus with two strong claws (vs. one strong claw for C. buehleri and C. gueryi). Its P 2 carpus is 4.3 – 5.5 times as long as wide and its P 5 propodus is 4.3 – 7.4 times as long as its dactylus (vs., respectively, 5.5 – 6.2 and 3.8 – 4.1 for C. buehleri). Its rostrum is armed with dorsal teeth, one – three of them situated on carapace behind orbital margin (vs. three – five for C. gueryi) and its P 5 dactylus has 31 – 33 spiniform setae on its flexor margin (vs. 26 – 31 for C. gueryi).	en	Mazancourt, Valentin de, Marquet, Gérard, Keith, Philippe (2024): An Integrative Taxonomic Revision of the Freshwater Atyid Shrimps (Crustacea: Decapoda: Caridea) of Micronesia.

D477D357D23DA52A7E93C6F0FD9D011B.taxon	discussion	Remarks This species is more similar to C. celebensis than to C. serratirostris by its shorter rostrum reaching to the base of the third segment of the antennular peduncle (vs. reaching beyond the end of the antennular peduncle), with fewer dorsal teeth, 19 – 21 (vs. 22 – 26); its longer P 2 carpus, 8.0 – 12.3 as long as wide (vs. 8.3 – 10.9), and P 2 chela 5.0 - 6.1 times as long as wide (vs. 3.7 – 5.1), but its shorter movable finger 1.3 – 1.4 times the length of the palm (vs. 1.7 – 1.9) and P 5 propodus 15.5 – 17.4 times as long as wide (vs. 18.7 – 24.0) and 4.1 times as long as the dactylus (vs. 4.5 – 5.5).

D477D357D23BA52B7E93C220FCEB063F.taxon	discussion	Remarks The single female specimen collected from Fai Fai Cave in Guam agrees well with the published descriptions of the species [51,61,63], having a rostral formula of 10 + 28 / 12 and a rostrum 1.19 times as long as the carapace. Interestingly, our sequence clusters with a 16 S sequence of the short-rostrum morph of the species from Miyako Island which is thought to represent the “ real ” C. rubella, whereas the long-rostrum morph from the same area potentially represents an undescribed species [60]. Consequently, it appears that this species is morphologically variable, as recently illustrated by De Grave et al. [61], but probably hides cryptic species. Amolecular study of this species from its whole range would be needed to clarify its status.	en	Mazancourt, Valentin de, Marquet, Gérard, Keith, Philippe (2024): An Integrative Taxonomic Revision of the Freshwater Atyid Shrimps (Crustacea: Decapoda: Caridea) of Micronesia.
