A New Species

Nineteen species of the neotropical gobiid genus Elacatinus are currently known from the western Atlantic, six of which are closely associated with sponges. Elacatinus colini is described as a new species of sponge-dwelling goby from Belize and Islas de la Bahía, Honduras. Formerly regarded as a color variant of E. xanthiprora (Böhlke & Robins) from Florida, it is differentiated principally by having a white instead of bright yellow stripe on the body, and 17 or 18 vs. 19 or 20 pectoral-fin rays. A second new species, E. serranilla, also formerly identified as a color form of E. xanthiprora, is described from three specimens from the Serranilla Bank in the Caribbean Sea (15°50’N, 79°50’W) and one from Jamaica (formerly a paratype of E. xanthiprora). It is distinct in having 10 dorsal soft rays (vs. 11 or 12 for E. xanthiprora), a bluish white dorsolateral stripe and median rostral band, longer dorsal-fin spines, and longer dorsal and anal soft rays. Elacatinus xanthiprora is presently known from Dry Tortugas (type locality) north to Miami in the Atlantic, and north to 28°41’N, 83°45’W on the Gulf coast of Florida, where the largest specimen (ANSP 148926, 43.1 mm SL) was collected at a depth of 26 m. Specimens off the east coast of Nicaragua in 27 m, and from nearby Isla de Providencia in 3–13 m, also previously identified as E. xanthiprora, probably represent two different undescribed species. Additional collection of specimens from the latter two localities is recommended for details of life color and DNA analysis.

A New Species

The present study focuses on shrimps belonging to the genus Lysmata Risso, 1816, collected from Madagascar during the Atimo Vatae expedition carried out in 2010. Lysmata malagasy sp. nov. is a new species belonging to the clade named “long accessory ramous” or “cosmopolitan” in previous phylogenetic studies. The new species can be distinguished from the only two other representatives of this group in the Indo-west Pacific, L. ternatensis De Man, 1902, and L. trisetacea (Heller, 1861), by the accessory ramus of the lateral antennular flagellum consisting of four elongated articles. Lysmata lipkei Okuno & Fiedler, 2010 is reported here from Madagascar with a remarkable extension of its known range after its original description from Japan. This species has also been reported from Singapore and, as alien species, from Brazil. Lastly, L. kuekenthali De Man, 1902 known from numerous localities in the Indo-West Pacific biogeographic area, is reported for the first time from Madagascar. Results of the present morphological and molecular analyses suggest that L. hochi Baeza & Anker, 2008 from the Caribbean Sea is a synonym of the Indo-West Pacific L. kuekenthali, and thus the latter species is alien in the western Atlantic.

A New Species

Bandy-bandies (genus Vermicella) are small (50–100cm) black and white burrowing elapids with a highly specialised diet of blindsnakes (Typhlopidae). There are currently 5 recognized species in the genus, all located in Australia, with Vermicella annulata the most encountered species with the largest distribution. Morphological and mitochondrial analyses of specimens collected from the Weipa area, Cape York, Queensland reveal the existence of a new species, which we describe as Vermicella parscauda sp. nov. Mitochondrial DNA analysis (16S and ND4) and external morphological characteristics indicate that the closest relatives of the new species are not V. annulata, which also occurs on Cape York, but rather species from Western Australia and the Northern Territory (V. intermedia and V. multifasciata) which, like V. parscauda, occupy monsoon habitats. Internasal scales are present in V. parscauda sp. nov., similar to V. annulata, but V. intermedia and V. multifasciata do not have nasal scales. V. parscauda sp. nov. has 55–94 black dorsal bands and mottled or black ventral scales terminating approximately 2/3rds of the body into formed black rings, suggesting that hyper-banding is a characteristic of the tropical monsoon snakes (V. intermedia, V. multifasciata and V. parscauda). The confined locality, potential habitat disruption due to mining activities, and scarcity of specimens indicates an urgent conservation concern for this species.

A New Species

Cestrus itatiensis sp. nov., from the Brazilian Atlantic Forest, is described and illustrated. This is the southernmost record for the genus and the first record in Brazil. The new species is characterized by having the body reddish brown; a narrow yellow stripe along eye margin on supra-clypeal area, reaching briefly the supra-antennal area; transverse carina of propodeum complete and stout; postpetiole and T2–8 progressively dark brown towards apical margin in a somewhat triangular pattern; and apex of dorsal valve of ovipositor with nine distinct teeth. Extensive sampling suggest this is a rare species.

A New Species

A new species of Gastrophanella, G. cavernicola sp. nov. (Demospongiae: Siphonidiidae), is described from submarine caves in Fernando de Noronha Island (north-east Brazil), Carrie Bow Cay and Columbus Cay, Belize (central Western Atlantic), at depths of 5-30 m. It differs from all other species of the genus by its lobate shape with thin superficial canals and centrotylote tylostrongyles. Gastrophanella cavernicola sp. nov. is the second record of the genus Gastrophanella from both Brazil and the Caribbean. It is the sixth ‘lithistid’ sponge reported from the Brazilian coast, whereas at least 32 other desma-bearing sponges are known from the Caribbean. The genus now includes five valid species, G. implexa Schmidt from the West Indies (type species), G. mammilliformis Burton from South Africa, G. primore Gómez from the Pacific Coast of Mexico, G. stylifera Mothes & Silva from south Brazil, and G. cavernicola sp. nov. from north-east Brazil and Belize. Aciculites oxytylota Lévi & Lévi from New Caledonia is transferred to Siphonidium Schmidt. The family Siphonidiidae Lendenfeld, which is probably related to order Hadromerida, is redefined to contain only Siphonidium and Gastrophanella, both with fused rhizoclone desmas associated to microspined exotyles.

A new species of the genus Tambja is described from the western Atlantic on the coast of Brazil. To date, the genus Tambja was represented in the Atlantic Ocean by nine species but only three of them have been recorded from the western Atlantic: T. gratiosa from the Gulf of Mexico, T. divae from Brazil and T. oliva from the Caribbean coast of the Isthmus of Panama. Tambja stegosauriformis sp. nov. is easily distinguished from all its congeneric Atlantic species of the genus by having very well developed light blue tubercles scattered on the yellowish-orange ground with an elongate crest behind the gill until the end of the tail. The anterior margin of the notum is very wide and elevated and it extends into a kind of lapel around the rhinophores. This peculiar external morphology and its conspicuous coloration characterize this species.

Occurrence Of Species

A species of the rudist bivalve genus Mexicaprina Coogan, 1973, from the mid-Cretaceous Mai Paso Formation of the Guerrero terrane, southwestern Mexico, is described as new: M. alata. At the type locality of this new species, a 6.5 m thick Mexicaprina-rich floatstone bed conformably overlies a taxonomically diverse build-up of reef corals. This type of facies relationship and implied faunal association has not been observed previously at any other site. Specimens of the type species, M. cornuta Coogan, 1973, also were found at the same locality, but 90 m stratigraphically below the lowest occurrence of M. alata. Compilation and detailed biostratigraphic analysis of the reported occurrences of Mexicaprina demonstrate that the age of the genus ranges from late Albian to early Cenomanian. However, most occurrences are late Albian and the Cenomanian age determinations are questionable and possibly late Albian also. The occurrence of species of Mexicaprina in the allochthonous Guerrero terrane, together with the relatively limited geographic distribution of the genus in the late Albian and early Cenomanian of the Gulf Coast of Mexico, Texas, and Honduras, indicates that this region of the Guerrero terrane was part of the Caribbean paleobiogeographic province during late Albian to early Cenomanian time. This occurrence also suggests that this portion of the Guerrero terrane was very close, possibly accreted, to the southwestern margin of North America by the close of the Early Cretaceous.

A distinctive new species of Typhlops is described from Parque Nacional Montaña de Santa Bárbara, 1550 m elevation, Departamento de Santa Bárbara, Honduras. The holotype and only known specimen of this new taxon is the largest specimen of the genus thus far reported from Mexico and Central America, and is further differentiated from all other Mesoamerican Typhlops by having 22–22–22 scales around the body and by having a dark brownish gray dorsum with a well-defined pale yellowish gray to immaculate white ventral coloration. This species is a member of the Caribbean Arc Group of Typhlops. An updated key to the Typhlopidae of Mesoamerica is provided.

A New Species

Six species of Branchiomma Kölliker (1858) from the Caribbean Sea and Pacific coast of Panama are described or redescribed, and a key for their identification is provided. All six have dorsal collar margins widely separate and thoracic uncini with few rows of teeth on the uncinal crests. Branchiomma nigromaculatum (Baird, 1865), B. bairdi (McIntosh, 1885) and B. conspersum (Ehlers, 1887) are redescribed from type material and designated lectotypes. Each has at least two pairs of macrostylodes, stylodes which are longer than their neighbouring pairs, flanking the middle area of each crown radiole. Those of B. nigromaculatum, a large-bodied species, are only twice as long as their neighbours, whereas those of the other two smaller species are more than four times as long. Stylodes are sub-digitiform in B. nigromaculatum, strap-like in B. bairdi and tongue–like in B. conspersum. Branchiomma nigromaculatum differs from B. bairdi and B. conspersum in having thoracic uncini with one row of large teeth on each thoracic uncinal crest (side view), covering less than a quarter of the crest length. Branchiomma curtum (Ehlers, 1901) is described as a new record for the Caribbean Sea. It has a few, small, digitiform stylodes and thoracic uncini with three rows of teeth, covering a half of the crest length. Branchiomma coheni is described as a new species from Naos, Pacific coast of Panama. It has broad, flattened, foliose stylodes, forming fairly even gradations of size throughout the radiole length, and thoracic uncini with two rows of teeth on the crest. Branchiomma iliffei is described as a new species from Bahamas. It has many, narrow, stylodes of similar size, unusually large radiolar eyes, a short crown (a quarter of the body length), short dorsal lips (a quarter of the crown length), long triangular ventral lappets and three rows of teeth, covering about one half of the crest length.
