Adaptive Value

A new Corydoras is described from the Blanco and Ucayali river basins in Peru. The new species can be distinguished from its congeners by having the following features: (I) posterior margin of dorsal-fin spine with laminar serrations directed towards the origin of the spine; (II) a long, wide, arched, and continuous black stripe, which runs parallel to the dorsal profile of the body, extending at least from the region below anterior origin of dorsal fin to the anterior half of the ventral caudal-fin lobe; (III) a black stripe transversally crossing the eye, forming the typical mask-like blotch; mask clearly not fused to arched stripe in most specimens; some specimens with mask separated from arched stripe by a thin line around the suture between neurocranium (in the region composed by the posteroventral margin of parieto-supraoccipital plus the posterodorsal margin of the compound pterotic) and first dorsolateral body plate; (IV) posterior margin of pectoral-fin spine with laminar serrations directed towards the origin of the spine; (V) pointed snout, presenting a long mesethmoid, with anterior tip larger than 50% of the entire length of the bone; and (V) ventral surface of trunk covered by small, non-coalescent platelets. A discussion on the possible positive adaptive value of the arc-striped color pattern is also provided.

We describe Anostomoides passionis, a new species of anostomid fish from rio Xingu. The species attains 306 mm SL and is distinguished from the other two congeneric species by the lateral line scale count (38–39, instead of 39–41 in A. atrianalis and 42–44 in A. laticeps) and by the color pattern: brownish-grey with two round to heart-shaped, dark blotches on the side (a larger one under the dorsal fin and another above the origin of the anal fin). Anostomoides passionis inhabits rocky stretches of the rio Xingu with moderate to high current. Stomach contents of two specimens of A. passionis caught during the low water season were composed mainly of fragments of sponges.

The genus Cephaloscyllium Gill 1862 (Chondrichthyes, Carcharhiniformes, Scyliorhinidae) until recently had only two species recognized, C. isabellum [= C. umbratile (Jordan & Fowler 1903)] and C. fasciatum Chan 1966, from the western North Pacific (WNP), with one dubious species, C. formosanum, having been described by Teng in 1962. Recently, three additional species were described, C. circulopullum Yano et al. 2005, C. sarawakensis Yano et al. 2005, and C. parvum Inoue & Nakaya 2006 from this region. Here we present a revision of this genus for the WNP, including redescriptions of C. fasciatum and C. umbratile based on the holotypes, a re-examination of the recently described species, and descriptions of two new species from Taiwan. Cephaloscyllium umbratile can be distinguished from its congeners based on maximum size, length of first dorsal-fin base, anal–caudal space, and dorsal–caudal space. We conclude, based on a comparison of C. parvum and C. sarawakensis, that the former is a junior synonym of the latter species. The two new Taiwanese species can be separated from other WNP species by color pattern, shape of the anterior nasal flap, anal and dorsal-fin size, internarial width, and mouth size. Finally, we present a revised dichotomous key to the WNP Cephaloscyllium recognizing six contemporary taxa: C. circulopullum, C. fasciatum, C. sarawakensis, C. umbratile, C. pardelotum sp. nov. and C. maculatum sp. nov.

Rivulus uatuman, new species, from the Rio Uatum drainage, central Amazonian basin, Brazil, is described. It is a member of an assemblage including R. amanapira, R. atratus, R. ornatus, R. kirovskyi, R. rectocaudatus, R. romeri, R. tecminae, and R. uakti, diagnosed by a unique pattern of frontal squamation and a derived color pattern of the infraorbital region. It shares three unique derived conditions with R. kirovskyi and R. romeri: small maximum adult size, third anterior supraorbital neuromast posteriorly positioned and absence of vomerine teeth. The new species differs from R. kirovskyi and R. romeri by having the dorsal fin posteriorly positioned, fewer pectoralfin rays, more vertebrae, and a white bar on the distal margin of the caudal fin in males.

A New Species

A new species of Crenicichla Heckel, C. hu, is described from the arroyo Piray–Miní, a left-hand tributary of the río Paraná, Misiones province, Argentina. This new species is easily distinguished from its congeners in the La Plata basin and adjacent coastal rivers by the dark coloration (dark grey or dark brown to black), a color pattern consisting of 7 to 9 black irregular blotches on the flank, and 47–54 scales in the E1 row. Adult females have dorsal fin with an irregular color pattern formed by wide black and white longitudinal stripes and blotches. In addition to standard morphological comparisons, a brief molecular phylogenetic analysis of Crenicichla species from the province of Misiones is also introduced.

Full Species

The full species status of Phyllomedusa burmeisteri bahiana was investigated based on tadpoles and vocalizations characteristics. We found distinct characteristics between the tadpoles and advertisement and territorial calls of the former and that of Phyllomedusa burmeisteri burmeisteri. The main tadpole differences are related with a skin projection protecting the spiracle, origin of dorsal fin, morphology of ventral fin and distribution of papillae on the oral disc. The advertisement call and territorial call of Phyllomedusa b. bahiana were different from the P. b. burmeisteri calls especially for the structure and temporal characteristics (pulses/second principally). The color of newly metamorphosed Phyllomedusa b. bahiana suggests that the color pattern of the internal sides of the thigh of P. b. burmeisteri can be related to a neotenic pattern of development. We elevate Phyllomedusa b. bahiana to species level based on morphological and acoustical traits decribed here.

A New Species

Bangana brevirostris, new species, is described from the Lancang-Jiang in Yunnan, Southwest China. It can be distinguished from all other congeners by the following combination of characters: a pair of minute rostral barbels; mental groove short and shallow; dorsal fin with 12–13 branched rays; 42–44 lateral line scales; eye large, its diameter 28.1–32.9 % of head length; snout short, its length 25.5–32.7 % of head length. It shares the same postlabial groove-type with Bangana dero and B. devdevi, which makes them very different from other congeners.

A New Species

We describe a new species of diurnal gecko, Gonatodes castanae sp. nov. from the foothills of the Serranía de San Lucas, municipality of Norosí, Department of Bolívar, Colombia. The new species differs from all species in the genus by the combination of the following characters: moderate size, subcaudal scale pattern type B (1’1’1’’), typically two rows of lateral scales on the digits, and aspects of color pattern in males (dorsum, flanks, limbs and tail with white ocelli on a black background) and females (dorsum, flanks, limbs and tail with brown to black reticulations and withe spots on a greenish-yellow background). The validity of the new species is also supported by molecular analyses. This species inhabits relicts of riverine forests at about 150 m above sea level (a.s.l.). Gonatodes castanae increases the number of known species in this genus to 34 and the species registered for Colombia to eight.
