AbstractA recent discovery of freshwater sponges in an unexplored hydrographic basin in north-western Australia provided the opportunity to investigate the genus Corvospongilla Annandale (Spongillida: Spongillidae) using integrative systematics. Emendation of the genus diagnosis is provided. A comparative analysis of a Corvospongilla global dataset of morphological traits together with biogeographic patterns disclosed a new Australasian Corvospongilla species and along with molecular analyses provided the basis for a phylogenetic and phylogeographic tree for some Asian, Afrotropical and Australasian lineages.

A new species of the genus Cyrtodactylus is described from Dien Bien Province, northwestern Vietnam based on morphological and molecular data. Cyrtodactylus ngati sp. nov. can be distinguished from remaining congeners by the following combination of characters: maximum SVL 69.3 mm; dorsal pattern consisting of six dark irregular transverse bands between limb insertions; inter-supranasals one; dorsal tubercles present on occiput, body, hind limbs and on first half of tail; 17–22 irregular dorsal tubercle rows at midbody; lateral folds clearly defined, with interspersed tubercles; 32–38 ventral scales between ventrolateral folds; 13 precloacal pores separated by a diastema of 5/5 poreless scales from a series of 7/7 femoral pores in enlarged femoral scales; precloacal and femoral pores absent in females; 1–3 postcloacal tubercles on each side; transversely enlarged median subcaudal scales absent. In the molecular analyses, the new species is shown to be the sister taxon to C. interdigitalis from Thailand. This is the 47th species of the genus Cyrtodactylus and the first member of the C. brevipalmatus species group recorded from Vietnam.

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.

Freshwater Environments

Two neogastropod species occur in brackish intervals in the Pebas Formation (late Middle to early Late Miocene) of Peru and Colombia in western Amazonia. Purpura woodwardi Roxo, 1924, is assigned to Melongena Schumacher, 1817 (Melongenidae), and ?Nassarius reductus (Nassariidae) is recognized as a new species. These gastropods are among the very few marine invaders in the otherwise freshwater Pebas fauna. The small number of marine to freshwater transitions among South American molluscs contrasts with the situation among South American fishes and southeast Asian molluscs. It may be related to seasonal fluctuations in water level and anoxia in present-day South American freshwater environments, as well as to predation and productivity.

A New Species

A new scincid lizard, Plestiodon takarai sp. nov., is described from the Senkaku Group, Ryukyu Archipelago, Japan. The Plestiodon lizards in this island group have previously been identified as P. elegans because they all exhibit a patch of enlarged and irregularly arranged scales on the posterior surface of their femurs. However, detailed molecular analyses revealed that the Senkaku population, although closely related to P. elegans and other species in the P. latiscutatus species group, is substantially diverged from all other recognized species. Furthermore, although the Senkaku population largely exhibits the characteristic morphological features of this species group, it can be differentiated from all recognized species by the scutellation and hatchling tail coloration. The biogeographical and conservation implications of these findings are briefly discussed.

A New Species

In this study, we describe a new orchid species, Goodyera malipoensis, from Yunnan, China. We have performed morphological and molecular analyses on this new species. A detailed comparison between the newly discovered orchid and other members of Goodyera was conducted. The new plant is characterized by having a dense brownish green pubescence on the peduncle. Its ovate-lanceolate petal is unique in Goodyera genus. The hypochile is deeply concave-saccate, and inside there are two papillose rows on each side. These features distinguish the new orchid from all other known species of Goodyera. The molecular study based on nuclear ribosomal ITS sequence data and morphological differences support G. malipoensis as a distinct species.

A New Species

A new colubrid snake, Rhynchocalamus ilamensis sp. nov., is described from Ilam province, western Iran. The new species differs from other described congeners using both morphological and molecular analyses. Morphologically, the head and neck color patterns are the most obvious distinguishing traits of this species from its congeners. The new species is separated from other species of Rhynchocalamus by a genetic distance of 9–13% in the mitochondrial Cytb gene, with R. satunini and R. melanocephalus as the closest and farthest relatives, respectively. As well, a color-based revised key to the genus is provided.

18S Rdna Gene

A new myxozoan was found parasitizing the freshwater catfish, Rhamdia quelen (Quoy & Gaimard), in the Marajó island, Amazon region, Brazil. The new species is described based on the results of morphological and molecular analyses. The parasite is approximately 1.5 mm in diameter and develops in the musculature of the host in the form of spherical, whitish cysts, which are visible macroscopically between the epaxial and hypaxial layers. When ruptured, these cysts produced ellipsoidal spores with a mean length of 11.4 μm (10.7–12.6) and width of 7.2 μm (6.4–7.9). Anomalous spores with a caudal elongation, vesicles in the peripheral portion of the spore and ornamentation of the valves were also observed. The results of the phylogenetic analysis of sequences of the 18S rDNA gene using Bayesian Inference indicated clear differences among the Myxobolus species that reinforced the taxonomic position of the parasite, confirming its status as a new species, denominated Myxobolus arariensis n. sp.

A New Species

Based on morphological and phylogenetic studies, Selaginella qingchengshanensis, a new species in S. sect. Heterostachys from Sichuan, China is described and illustrated. Morphologically, the new species is similar to S. amblyphylla, but has sterile leaves with denticulate to slightly ciliate margins, dorsal leaves with long arista (as long as leaves) perpendicular to stems and branches in living plants, and axillary leaves triangular-ovate or broadly ovate. Molecular analyses based on ITS+5.8S and rbcL data also support it as a distinct species.
