A New Species

The genus Acanthistius Gill, 1862 comprises ten putative valid species occurring in shallow warm-temperate waters of the Southern Hemisphere: South America (coasts of Ecuador, Peru, Chile, Brazil, and Argentina) southern Africa (Namibia and South Africa), southern Australia, New Zealand, Lord Howe, Norfolk, Kermadec and Easter, and Sala y Gómez islands. Two species: Acanthistius sebastoides (Castelnau, 1861) and Acanthistius sp are known from shallow waters of the east coast of South Africa (Heemstra and Randall, 1986). The latter taxon, previously known from a brief description of a single specimen, is here described from 23 specimens and named Acanthistius joanae. Acanthistius sebastoides is redescribed from 13 specimens and compared with A. joanae and species of Acanthistius known from South America and Australia. A neotype is designated for Serranus sebastoides Castelnau, 1861, as the two syntypes are apparently lost.

AbstractPlagioscion squamosissimus(Heckel, 1840) (Osteichthyes: Sciaenidae) is considered piscivorous and is a generalist species endemic to the Amazon region. This fish is an important part of the natural ecosystems in which it occurs and provides basic functional components in the food web. The genusNeoechinorhynchusStiles & Hassall, 1905 is distributed worldwide and parasitizes fish and turtles, but there are few reports of parasites of this genus in South America, due to the high diversity of fish that can be found in this region. A new species of thorny-headed worm (Acanthocephala: Neoechinorhynchidae) is described fromP. squamosissimusfrom Guajará Bay, Belém, Pará, Brazil. In general, the unique characteristics of the hooks on the anterior end of the proboscis and the length-to-width ratio relationship separate this new species from other described species in the genusNeoechinorhynchus. Although the species in this genus are mostly found in North America, the dearth of species known from the neotropics may be due to the lack of studies in this region.

A New Species

The genus Trachelopachys Simon, 1897 was erected to accommodate Trachelas sericeus Simon, 1886, a species known from southern South America. Platnick (1975) presented a taxonomic review of the genus and Platnick & Rocha (1995) added a new species and transferred two additional species to the genus, raising the known species diversity of Trachelopachys to 15 species. The genus is distributed in South America, their members are small and colorful, and are distinguished from other trachelines by their darkened carapace, the S-shaped tegular sperm duct and the retrolaterally directed embolus of the male palp (Platnick 1975: fig 12), and the presence of a basal spermathecal lobe in females (Platnick 1975: fig 15). Here we describe the 16th species of the genus, Trachelopachys camarapi sp. nov. (Fig. 1), known from both sexes and recorded in a natural savanna (Fig. 2) at Portel municipality, state of Pará, Brazil.

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

A New Species

A new species of scaly blenny, Labrisomus conditus sp. n., is described from Fernando de Noronha Archipelago, off northeastern Brazil. It differs from its Western Atlantic congeners by the following combination of characters: nuchal cirri when depressed not reaching dorsal-fin origin, 68 to 73 lateral line scales, first and second dorsal-fin spines slightly shorter than third spine and not flexible, numerous pale dots overall (light blue in life), opercular dark spot with incomplete and diffuse broad pale margin (orange in life). The new species is a territorial bottom-dweller in rocky shores and is found among algae and in crevices at depths from 0.5 to 6 m. Labrisomus conditus sp. n. feeds mostly on crustaceans (crabs, amphipods) and molluscs (snails, bivalves). The new species increases to five the species within the genus Labrisomus recorded from Southwestern Atlantic.

A New Species

A new species of eurysquilloid stomatopod,Eurysquilla petronioisp. nov., is described from the tropical western Atlantic.Eurysquilla petronioisp. nov. is the fourteenth species of the genus to be recognized worldwide, the fifth species from the western Atlantic and the second from Brazilian waters. It is most closely related toE. maiaguesensisfrom Puerto Rico, but differs chiefly in having an unarmed versus apically spinous rostral plate and 6 or 7 rather than 8–10 teeth on dactylus of raptorial claw. A key to the species of the genus is provided.

A New Species

Paspalum chilense, a new species from Chile belonging to the informal Notata group, is described and illustrated on the basis of morphological, cytological and molecular evidence. Our evidence supports its affinity with P. barretoi and P. nummularium, from Brazil, from which it probably diverged by vicariant speciation. The limited available material of the new species was previously identified as P. pumilum or P. minus. A new key to the species of the core Notata group is provided.
