Detailed morphological comparison with Alpheus malabaricus (Fabricius, 1775) and other taxa earlier synonymized with the former species are provided. The trophic position of the new species was evaluated based on analysis of δ15N/δ13C stable isotopes, and a discussion on other ecological features of the species is also represented in the article.KEY WORDS: Crustacea, diversity, mangroves, communities, Asia, Indo-West Pacific.Order Decapoda Latreille, 1802 Infraorder Caridea Dana, 1852 Family Alpheidae Rafinesque, 1815 Genus Alpheus Fabricius, 1798Alpheus cangiopalus sp. n., habitus, showing living coloration:a — holotype ♂, ZMMU Ma-6233, lateral and dorsal views;b — paratype ♂, ZMMU Ma-6235, lateral and dorsal views.Alpheus cangiopalus sp. n. ETYMOLOGY. The species name, cangiopalus, was given after Cần Giờ Mangrove Biosphere Reserve; and the habitat of the new species, “palus” (Latin.) means “swamp”.

Read more Les syndicats de médecins libéraux en grève depuis lundi ont rejeté la proposition de rendez-vous en marge de leur manifestation parisienne samedi, que leur avait adressée la ministre de la Santé Stéphanie Rist. L'ensemble de l'intersyndicale "a décidé de ne pas se rendre" au rendez-vous proposé vendredi par Stéphanie Rist, "qui ne nous semble pas de nature à modifier le cours des lois votées ou des projets de loi en attente de vote", écrivent les syndicats dans une lettre commune à Mme Rist, diffusée vendredi soir. "Votre ministère sait depuis longtemps les points bloquants dont vous n'avez pas pu ou su ou voulu empêcher le vote", ont-ils ajouté. Show less

The new species is distinguished from all other congeners by the following combination of characteristics: dorsal-fin rays VI-I, 9 (rarely 10); anal-fin rays I, 9 (rarely 10); pectoral-fin rays 15–17; longitudinal scale series 26–32 (modally 29); transverse scales 9–12 (modally 10); pre-dorsal scales absent; first to fourth spines of first dorsal fin each with a filamentous tip (usually fourth spine longest; second and third spines of similar length; first spine shortest); head and nape naked; body mostly covered with ctenoid scales; cycloid or weakly ctenoid scales on thorax and just above pectoral-fin base; two brown stripes from just behind pectoral-fin base to caudal-fin base; five dark brown lateral blotches (rarely 6) on body, between lateral stripes; blue spots (sometimes indistinct) between and just above lateral stripes when fresh, but indistinct or absent on lateral blotches; black blotch on opercle; paired black spots on chin; single black spot on spine tip of second dorsal fin; longitudinal yellow (sometimes reddish-yellow) stripe on upper margin of caudal fin, just above longitudinal bluish stripe. The new species is similar to A. suluensis and Acentrogobius violarisi Allen 2015 in having a ladder-like lateral pattern on the body and a black blotch on the opercle but differs in having a naked pre-dorsal area, paired black blotches on the chin, a distinct black spot in the spine tip of the second dorsal fin, and yellow and blue stripes on the upper margin of the caudal fin, and lacking transverse red stripes and vertical black blotches laterally on the body.Keywords: Taxonomy, Morphology, Yongeichthys, COI mt DNAAcentrogobius nigromaculatus sp. nov. (New English name: Spotted Ladder Goby; new standard Japanese name: Itten-hohoguro-suji-haze)Etymology.
