A New Species

Parotocinclus halbothiis described as a new species from the Trombetas and Marowijne river basins, in Brazil and Suriname. The new species is distinguished from its congeners in the Guianas, Orinoco, and Amazon basins by details of color pattern, form and arrangement of bony plates, body shape, and morphometric features. It is distinguished from all other species of Parotocinclusby the elongation of the canal cheek plate on the ventral surface of head posteriorly to contact the cleithrum. The new species is differentiated from Parotocinclus collinsae, the most similar species in terms of color pattern, by the small, circular, median abdominal plates, the poorly developed preanal shield with two or three plates, and by having the adipose fin rudimentary. This new species is one of the smallest loricariid catfishes known to date.

A New Species

Background and aims – The genus Anemopaegma (Bignoniaceae) includes around 47 species and has its centre of diversity in Brazil. Here, we describe and illustrate a new species from French Guiana, Anemopaegma kawense, and compare it to the two most similar species, A. foetidum and A. granvillei. We further assess the conservation status of all three species.Material and methods – Morphological descriptions are based on herbarium specimens deposited at BM, BR, CAY, INPA, K, MO, P, SPF, and U, and, in the case of the newly described species, also on field observations. The conservation status assessments follow the IUCN Red List criteria.Key results – Anemopaegma kawense differs from both A. foetidum and A. granvillei by its densely villose twigs, longitudinally plicate leaflets with secondary veins not or hardly prominent below, and tertiary veins impressed below. It is further separated from A. foetidum by the leaflets that are villose below and the calyx that is entirely pubescent outside. On the other hand, A. kawense differs from A. granvillei by the densely lepidote outer surface of the corolla, shorter petiolules, leaflets with midrib impressed above, shorter bracts and bracteoles, inflorescence peduncle exceeding the rachis, and pedicels densely puberulous, not lepidote or only sparsely so at the apex. This species is endemic to the Kaw Mountain in north-eastern French Guiana, where it grows in low stunted forest on laterite; it is assessed as Endangered according to the IUCN criteria. New descriptions are provided for A. granvillei, which is newly reported from Suriname, and for A. foetidum, which is newly reported from French Guiana; these two species are assessed as Endangered and Least Concern, respectively. Lectotypes are designated for A. maguirei, which is here synonymised with A. foetidum, and for A. umbellatum, another synonym of that species. A key to the 12 species of Anemopaegma occurring in the Guianas is presented.

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.

A New Species

A new species, Pimelodus britskii, is described from the rio Iguaçu in the rio Paraná drainage, on the border of Paraná and Santa Catarina states, Brazil. Specimens of this species were wrongly included in the type series of Pimelodus ortmanni. Pimelodus britskii is distinguished from its congeners by color pattern, having circular dark brown blotches usually smaller than one orbital diameter, regularly and scattered along the trunk. Differs from P. ortmanni by the following characters: body depth at posterior cleithral process greater than head length; lips not prominent; and maxillary barbel reaching or surpassing vertical drawn through median of adipose fin. Pimelodus britskii represents the second species of the genus Pimelodus from the rio Iguaçu basin.

A New Species

In the present study we provide evidence for the validity of the genus Trigonodactylus Hass, 1957, improve the diagnosis for this genus and describe a new species that belongs to it—Trigonodactylus persicus sp. nov., from the sand dunes in Khuzestan Province, southwestern Iran. The new species is closely related to Trigonodactylus [Stenodactylus] arabicus sensu Hass, and can be distinguished by the following morphological characteristics: small size, maximum SVL 34 mm; SVL/TailL—approximately 1:1; ventral scales roundish, weakly keeled, 54–61 longitudinal rows at midbody and 190–25 along midbody. No enlarged postmentals. Fingers and toes slightly flattened dorso-ventrally. Lateral edge of digits fringed by series of projecting triangular scales. No web between digits. No preanal and femoral pores. Dorsal color pattern formed by thin, dark, irregular vermicular patches and spots. Sometimes these dark dorsal patterns blend with each other and form transverse bands. There is a narrow, dark, longitudinal line between forelimbs and hindlimbs on lateral sides. Dark, well developed ʌ-shaped marking on snout, which continues behind orbit on tympanum region, approaches the upper ear opening and ends on the pectoral arch. Labial scales white, in some cases with grey-brown dots. Dorsal surfaces of limbs and digits with irregular dark bands. Dorsal surface of tail with 8–10 wide, dark brown bands with irregular margins, same size as alternating light bands. Ventral surface of body and limbs white, tail with dark spots that become more distinct posteriorly.

The Oriental genus Andreimyrme Lelej, 1995 is newly reported from India. A new species A. paniya sp. nov. is described based on a female specimen from Kerala part of Western Ghats. Diagnostic features of this new species to separate it from similar species A. neaera (Mickel, 1935) and A. sarawakensis Lelej, 1996 are discussed. This new species has the mesosoma and metasoma with reddish-brown cuticle which approximates Eastern mimicry ring in North America. Andreimyrme paniya sp. nov. expresses a rare color pattern. In India such color syndromes occur in two species of the tribe Smicromyrmini and two species of the subfamily Dasylabrinae. These species inhabit the tropical moist broadleaf forest ecoregion of southern India. An updated diagnosis for males and females of Andreimyrme is given.

Megatibicen harenosus sp. n. is described from the Mescalero-Monahans shinnery sands of New Mexico and Texas, U.S.A. The new species is diagnosed from similar species, especially M. tremulus which it resembles closely, by male genital morphology, color pattern, calling song, and ecology. Seven characters from the male calling song are described from analysis of field recordings, of which all four temporal song characters are significantly different from M. tremulus. With one of the most southwestern distribution of any Megatibicen species, M. harenosus is a new addition to the rich, endemic, and understudied Mescalero-Monahans shinnery sands biota. The possibility that M. harenosus and M. tremulus are sister species is raised. The ecological, biological, and evolutionary species concepts support species status for M. harenosus, and an hypothesis of peripatric speciation in peripheral isolation is advanced.
