A New Species

A new species of the lacertid genus and subgenus Eremias is described based on material collected by the senior author from 150 km northeast of Shiraz, Fars province, south-central Iran at about 1800 m elevation. It differs from all other Iranian species of the typical subgenus (E. persica, E. strauchi, E. velox, and E. lalezharica) in that it has a very distinctive and unique color pattern, unmistakable in this character: the wide dorsolateral stripe is uniformly black without light spots and there is no ocelli on the upper surface of limbs; the third pair of submaxillary shields are separated by 4 granular scales; and the tympanic shield is rudimentary and almost absent. The new species is sympatric with Eremias persica and apparently restricted in distribution to the steppes and open plains in the northern regions of Fars province, south-central Iran.

A New Species

Abstract A new species of Characidium is described from the tributaries of the rio Tocantinzinho, rio Tocantins basin, located in the southern portion of the Chapada dos Veadeiros, at about 1,200 meters of elevation, Goiás, Brazil. The new species can be diagnosed by an unusual combination of two apomorphic features present in distinct clades of Characidium, the presence of a scaleless isthmus in allied to with a single row of dentary teeth. Additionally, the new species has a unique color pattern of inconspicuous vertical bars disconnected from the dorsal midline, forming seven to nine square blotches along body sides, and the presence of a dark saddle-shaped mark at the dorsal-fin base. Osteologically, it can be diagnosed by having the first and second anal-fin proximal radials fused and contacting the third hemal spine, which is branched. The new species also has a peculiar, unusual variation of fin-ray counts among its congeners.

A New Species

ABSTRACT A new species of Ituglanis associated to the grasslands of the Pampa biome is described from the rio Uruguai basin, southern Brazil. The new species is distinguished from its congeners by the low number of ribs and by a unique color pattern composed of an outer layer with scattered round black blotches equivalent in size to the eye circumference over a reddish brown background on the lateral surface of the body. We provide the genetic sequences of the mitochondrial gene Cytochrome c Oxydase subunit I (COI) for three of the paratypes and discuss aspects about the recent discovery of the new species.

A new species of Microglanis is described from the upper rio Tocantins basin, Barro Alto, Goiás State, Brazil. This species is distinguished from the others by presenting a unique color pattern, consisting of round spots in the flank between the larger dark brown blotches. Moreover, it can be distinguished by the combination of the following features: caudal fin emarginate, the upper lobe slightly larger than the lower, lateral line relatively long, reaching vertical through posterior margin of the pelvic fin, and light stripe on supra-occipital region absent or very narrow and with irregular shape.

A New Species

We describe a new species of the iguanian genus Liolaemus of Northwestern Argentina in Salta Province. This new lizard is a member of the L. boulengeri group, and within this group it is a member of the L. darwinii subgroup. With the addition of the species described here, the L. darwinii group now contains 19 species. Like most of the members of this group, the new taxon exhibits sexual dichromatism, showing a unique color pattern in males and females. The color pattern is characterized by the presence of a pre-scapular spot and lateral black stripes, unique within the L. darwinii group. Liolaemus diaguita sp nov inhabits a region where bushes are the predominant vegetation, in Quebrada de Las Conchas, in Guachipas Department, Salta Province, which has an elevation between 1200–2500 m.

Rio Madeira

A new species of Hypostomus, H. dardanelos, is described from the rio Aripuanã basin, a southern tributary to the rio Madeira, in northern Mato Grosso State, Brazil. The new species is assigned to the Hypostomus cochliodon group by the possession of few teeth, spoon-shaped teeth, angle between dentaries usually less than 80°, and by the absence of a notch between hyomandibular and the metapterygoid. The new species can be diagnosed from its congeners by its unique color pattern of yellowish-brown ground color covered by well-defined dark spots of relatively equal size, evenly spaced and moderately set along the dorsal region of the body and fins, except on the ventrolateral region of the caudal peduncle and proximal region of anal and caudal fins, which are devoid of spots. The new species is further diagnosed by having teeth with very small lateral cusp, fused to the mesial one and almost imperceptible; by the absence of medial buccal papillae, and by nuptial odontodes all along the body (odontodes more pronounced in some few larger specimens).

A new species of jawfish, Opistognathus pardus, is described based on a single specimen, 98.8 mm SL, recently collectedfrom the Western Indian Ocean off Quilon (Kerala), India. The combination of a rigid maxilla without flexible lamina pos-teriorly, a unique color pattern in which most of the head is covered with small, irregular-shaped, dark spots, dorsal-finrays XI, 11, and the outermost segmented pelvic-fin ray tightly bound to adjacent ray, with the interradial membrane notincised distally distinguishes the new species from other congeners. This is the fourth species of Opistognathus known from the coast of India or Sri Lanka. A range extension for O. macrolepis is also reported.

A New Species

A new species of limestone karst-adapted gecko of the Cyrtodactylus pulchellus complex, C. dayangbuntingensis sp. nov., is described from Dayang Bunting Island of the Langkawi Archipelago off the northwest coast of Peninsular Malaysia. It is the third species of the group to be described from the archipelago after C. langkawiensis and C. macrotuberculatus. The new species can be distinguished from all other species of Cyrtodactylus based on molecular evidence from the mitochondrial gene ND2 and its flanking tRNAs as well as having unique combinations of morphological and color pattern characteristics. This discovery underscores the need for continued surveys of the many islands in the archipelago to properly ascertain its true herpetological diversity.

A new species of Hemigrammus is described from the upper Rio Negro, Amazon basin, Brazil. The new species is distinguished from all congeners by its unique color pattern consisting of a single humeral blotch clearly spaced from a conspicuous midlateral dark stripe, which extends from fifth or sixth anteriormost vertical scale row to the basis of the middle caudal-fin rays. Comments on its putative relationships are provided.

A New Species

Hyla ephemera, new species, is described from the cloud forests of Cerro Las Flores in south-central Oaxaca, Mexico. We tentatively place this species in the phenetic H. bistincta group. It is most similar to H. calthula in color pattern but differs in having a greater snout–vent length, a relatively shorter snout and tibia, a relatively wider head, and a larger tympanum. We also report an additional locality record for H. calthula, previously known only from the type locality.

A New Species

A new species of Dwarf Snakes, Eirenis rafsanjanicus sp. n., is described from south-central Iran. This species is well distinguished from other congeners in both molecular and morphological characters, and its description increases the number of described Eirenis species to 26. Eirenis rafsanjanicus sp. n. is genetically closest (6% in Cytb) to the recently described E. yassujicus, which inhabits high habitats in southern Iran. Morphologically, E. rafsanjanicus sp. n. is more similar to E. modestus than to other congeners. A revised key to the genus is presented.
