A New Species

To date, only one species of Temnocephala is known from Chile, Temnocephala chilensis, and three from southern Argentina (Patagonia), namely T. chilensis, Temnocephala dionii, and Temnocephala mexicana. Here we describe a new species of Temnocephala and provide an updated description of T. chilensis based on material found on an anomuran crab (Aeglidae) from southern Chile. Additional hosts and localities are reported for both species in southern Argentina and Chile, and a diagnostic key for all species of Temnocephala hosted on Aegla and Parastacidae is included as well. In southern Chile, both T. chilensis and the new species were found on the crayfish Samastacus spinifrons and on the anomuran crabs Aegla abtao and Aegla alacalufi; in addition, the new species was found on Aegla manni, and T. chilensis on Aegla rostrata. In southern Argentina, T. chilensis and the new species were found on Aegla riolimayana and S. spinifrons. Based on their shared traits (morphology of the penial stylet, host preferences and geographic distribution), the temnocephalans hosted in Aegla are tentatively gathered into two clusters, the Chilensis and Axenos groups.

A New Species

Eschweilera sphaerocarpa (Lecythidaceae) is described here as a new species for science. It is closely related to Eschweilera complanata. Due to an area of occupancy of less than 10 km² this species is regarded as endangered according to the standards of the IUCN. This paper provides a description, illustration and, comments on geographic distribution and ecology. Additionally, a diagnostic key to the species of Eschweilera section Tetrapetala is provided.

Molecular Characters

Formerly Cnemidophorus was thought to be the most speciose genus of Teiidae. This genus comprised four morphological groups that were later defined as four different genera, Ameivula, Aurivela, Cnemidophorus and Contomastix. The last appears as paraphyletic in a recent phylogenetic reconstruction based on morphology, but monophyletic in a reconstruction using molecular characters. Six species are allocated to Contomastix. One of them, C. lacertoides, having an extensive and disjunct geographic distribution in Argentina, Uruguay and Brazil. Preliminary analyses revealed morphological differences among its populations, suggesting that it is actually a complex of species. Here, we describe a new species corresponding to the Argentinian populations hitherto regarded as C. lacertoides, by integrating morphological and molecular evidence. Furthermore, we demonstrate that the presence of notched proximal margin of the tongue is a character that defines the genus Contomastix.

A New Species

A synopsis of the genus Cnidoscolus is presented for the midwestern region of Brazil, which resulted from the analysis of about 1,200 specimens from 62 national and foreign herbaria, including type collections. Observations of populations in field were also made. Nine species are recognized, one of which, C. mcvaughii, is new to science. It is described and illustrated, and comments about its geographic distribution, morphological relationships, systematic position, phenology, and conservation status are provided, as well as images and a map. The other species are contrasted by a dichotomous key. Also, distributional information, maps, conservation evaluations, images and morphologically diagnoses are included. Eight synonymizations, one lectotypification, a neotypifcation, and the re-establishment of C. neglectus are proposed.

A New Species

The name Salicornia cuscoensis given to a plant from high Andean saltmarshes near Cusco [Cuzco] and Ayacucho, Peru (South America) is validated by a diagnosis and description. The main morphological characters that separate S. cuscoensis from other closely related species are creeping habit, delicate branches, inflorescence of short and thin spikes, and seed indumentum. The new species clearly differs from other perennial Salicornia taxa growing in high Andean saltmarshes such as S. pulvinata and S. andina. The former forms small compact cushions producing very short, few-flowered inflorescences. The latter shows woody stems and forms larger rounded carpets. Morphologically, S. cuscoensis is also similar to S. magellanica, a species growing along the seashore in southern Patagonia and Tierra del Fuego, but the latter has shorter and wider inflorescences and larger seeds with a different type and arrangement of indumentum. Molecular analyses also supported the separation of S. cuscoensis. Data on habitat, distribution and phylogenetic relationships are presented for the new species and its relatives, and an identification key is given for the South American taxa of the genus Salicornia.

This work deals with haplosclerid sponges off the coast of Maranhão State, northeastern coast of Brazilian shelf (southwestern Atlantic). A new species is described, Haliclona (Halichoclona) lernerae. Four species are recorded for the first time for the Brazilian coast: Amphimedon caribica (Pulitzer-Finali, 1986); Niphates lutea Lehnert & Van Soest, 1999; Neopetrosia subtriangularis (Duchassaing, 1850) and Petrosia (Petrosia) weinbergi Van Soest, 1980. Three species were recollected from the southwestern Atlantic and have their geographic distribution extended on the Brazilian coast: Callyspongia (Cladochalina) vaginalis (Duchassaing & Michelotti, 1864), Oceanapia bartschi (De Laubenfels, 1934) and Xestospongia muta (Schmidt, 1870). Two species were collected for the first time from the Maranhão State Coast: Niphates erecta Duchassaing & Michelotti, 1864 and Neopetrosia proxima (Duchassaing & Michelotti, 1864). A taxonomic study of those samples is given, including description, illustrations and geographic distribution.

A New Species

Pareiorhaphis nasuta, a new neoplecostomine catfish of the family Loricariidae is described. The species was collected from headwaters of the rio Matipó, tributary of the upper rio Doce basin in State of Minas Gerais, Brazil. The new species is readily diagnosed from all remaining congeners by the longer snout and by the smaller orbital diameter. The new species is the first representative of the genus Pareiorhaphis discovered in the rio Doce basin, thus expanding its geographic distribution. A phylogenetic diagnosis for Pareiorhaphis is presented.

A new species of Specklinia with a repent growth habit and minute purple flowers is described and illustrated. The new species is distinguished from Specklinia wrightii based on its morphological and molecular distinctness from that species. The phylogenetic placement of the new species is provided based on an nrITS tree. The species described here represents the first new orchid to be described from material originating from the Parc National Naturel Macaya in six years. New combinations are made in Acianthera for species of Kraenzlinella and Pleurothallis subgen. Antilla embedded within the genus. In particular Kraenzlinella rinkei is provided as a new synonym for Specklinia montezumae and Specklinia simpliciflora is transferred to Acianthera sect. Antilla based on morphology and geographic distribution.

The species of Charaxwere reviewed by Lucena (1987) who a little later (1989) added three new species to the genus. Examination of recently collected specimens from museum collections documented the more extensive geographic distribution for most species and revealed the existence of a new species in which superficial neuromasts were discovered and are herein described. These skin structures were also detected in C. metae Eigenmann, 1922. Anal- and pelvic-fin hooks previously observed only on the anal-fin of one species of the genus are described herein in some other species. Charax unimaculatus Lucena is considered a junior synonym of C. michaeli Lucena. All the species are redescribed and the new species described.
