“…3c) smaller than that of male but similar in morphology; ischium with three lower spines; merus with upper longitudinal tuberculate crest and three spines; propodus with tubercles and one upper subdistal spine (here broken); both fixed finger and dactylus slightly arcuate, with curved tip, fixed finger shorter than dactylus with large proximal tooth and small round teeth on the rest of cutting edge; dactylus with two quadrate proximal teeth and another one near midlength of cutting edge and small teeth on distal half, as in the male. Pereopods 1 of both sexes in Vietnamese specimens agree with the description given by Ngoc-Ho et al (2005) and therefore are similar to or at least not significantly different from those from Thailand or Malaysia.…”

“…Four specimens deposited in the MNHN, Paris are compared with those from Thailand and Malaysia, on which previous works by Ngoc-Ho (1998) and Ngoc-Ho et al (2005) were based, and also with the female holotype and only known specimen of E. crosnieri. Addditional remarks, especially on the status of the latter species, are provided by the second author.…”

The rare thalassinid shrimp, Eutrichocheles modestus (Herbst, 1796) is now recorded from South Vietnam. It was previously collected in Thailand and Malaysia, and was dealt with in Ngoc-Ho (1998) and Ngoc-Ho et al. (2005).The Vietnamese specimens are described in detail and variations are discussed. They are compared with specimens from Thailand and Malaysia, and with the female holotype of Eutrichocheles crosnieri Ngoc-Ho, 1998, also from Vietnam. Additional remarks, especially on the status of the latter species, are presented.A note on the habitat, fishery, and economic importance of E. modestus in Vietnam is provided. This study shows that the only female of E. modestus from Vietnam, as well as the one from Thailand, differ from the holotype of E. crosnieri by certain features, and no males examined can be assigned to this latter species. The two species are here kept separate, pending a future study of additional material, especially from the type locality of E. crosnieri. RÉSUMÉLa rare crevette thalassinide Eutrichocheles modestus (Herbst, 1796) est maintenant récoltée au Sud Vietnam. Elle a été signalée auparavant en Thailande et Malaisie et traitée dans Ngoc-Ho (1998) et Ngoc-Ho et al. (2005). Les spécimens du Vietnam sont décrits en détail et les variations sont discutées. Ils sont comparés à ceux de Thailande et Malaisie et à la femelle holotype d'Eutrichocheles crosnieri Ngoc-Ho, 1998, Une note sur l'habitat, la pêche et l'importance économique d'E. modestus du Vietnam est fournie.Cette étude montre que la seule femelle d'E. modestus du Vietnam, comme celle de Thailande, se distingue de l'holotype d'E. crosnieri par certains caractères et aucun mâle étudié ne peut être attribué à cette dernière espèce. Ces deux espèces sont ici séparées en attendant un apport supplémentaire de matériel, provenant de la localité type d'E. crosnieri spécialement.

“…8 mm). His differentiation was accepted with minor discrepancies by Ngoc-Ho et al (2005) who redescribed E. modestus Wood-Mason, 1876, type species of Eutrichocheles. Kensley (1996a) diagnosed Paraxiopsis as lacking male pleopod 1 but one male of P. pumilus displays minute digitiform male pleopods 1 (see fi g. 30e) as in species of Eutrichocheles (NgocHo et al, 2005).…”

A new species of axiid was discovered during sampling offshore deep banks on the middle continental shelf off Louisiana. Paraxiopsis kensleyi n. sp. appears to inhabit interstices and cavities of coralline algal rubble, rhodoliths, coral rubble, and other eroded calcareous substrates. Weakly separated from Eutrichocheles Wood-Mason, 1876 on the basis of morphology, present assignments of western Atlantic species to Paraxiopsis de Man, 1905 are regarded as provisional. The new species is described morphologically, and the coloration of freshly captured specimens is documented and compared to related species where possible. Coloration readily distinguishes mature specimens of the new species from Paraxiopsis spinipleura Kensley, 1996, with which it was initially confused. The diagnosis includes GenBank accession numbers for COI sequences to allow future molecular phylogenetic comparisons. Compared to regional species that share a similar dentation or spination on the submedian carina, the pleon of the new species is distinctive in the truncate ventral margin on pleura 2–4, as opposed to being broadly rounded or directed ventrally in an acutely triangular tip. The new species is the eighteenth species of Paraxiopsis worldwide and the ninth from western Atlantic waters, seven of which are now known to range into the Gulf of Mexico. An updated key to western Atlantic members of the genus is provided.
