A New Species

Abstract Culex longitubus Somboon, Namgay & Harbach is described as a new species of the Mimeticus Subgroup of the subgenus Culex. The larva is most similar to the larva of Cx. tianpingensis Chen from China, but is distinguished by the length of the siphon and the anal papillae, the form of the comb scales and pecten spines, and the development of setae 7-P, 13-T, 1-X, and 4-X. The adults have wing markings and male genitalia similar to those of species of the Mimeticus Complex. Phylogenetic analysis of COI sequences revealed that the new species is closely related to Cx. murrelli Lien of the Mimulus Complex. The immature stages of the new species were found in stagnant pools and marshes at high altitudes in several districts of Bhutan.

Abstract A new species of miniature fish of the characid genus Priocharax is described from a small lake near the rio Ipixuna, rio Purus drainage, Amazonas State, Brazil. It is distinguished from all congeners except P. pygmaeus by the lower number of teeth on the maxilla and dentary. It differs from P. pygmaeus by the presence of two postcleithra and 22–27 branched anal-fin rays (vs absence and 19–22). The new species is further distinguished from other species of Priocharax by a combination of characters involving the number of pelvic-fin rays and branched anal-fin rays, the number of postcleithra, the shape of postcleithrum 3, and the absence of the claustrum. Molecular evidence based on COI sequences of all valid species of Priocharax also corroborates the validity of this new species.

Xyliphius anachoretes, a new species of aspredinid catfish is described from the Tocantins-Araguaia River system. Xyliphius anachoretes is diagnosed by the presence of six developed retrorse serrae on posterior border of pectoral-fin spine, presence of papillae on the lower lip bearing minute branches, and only two dorsal procurrent rays. Comments about the informativeness of character-state variation among Xyliphius species and aspredinid related genera are furnished. Also, a brief discussion about conservation status of the new taxon is made.

A New Species

A new species, Baetis pentaphyllus sp. nov., is described on the basis of larvae from the Far East of Russia (type locality Bolshoi Garmakan River). Larvae of Baetis pentaphyllus sp. nov. may be distinguished from other Baetis species by the presence of only five pairs of tergalii on segments III–VII. The mitochondrial COI sequence obtained from the described species was compared with the data present in GeneBank and BOLD. The DNA barcodes allowed discrimination of B. pentaphyllus sp. nov. from other species of Baetis with available sequence data. The average interspecific K2P distances were 10–15%, which are values well above those associated with intraspecific variation. COI sequences as well as 36 morphological larval characters were analysed using Bayesian inference to relate the described species to the recognized species-groups of the Baetis genus. B. pentaphyllus sp. nov formed a sister clade to B. vardarensis + B. lutheri which belong to the Baetis lutheri species-group.

Acanthemblemaria aceroi new species is described from the upwelling region of the Caribbean coasts of Venezuela and Colombia. It differs from its closest relative, Acanthemblemaria rivasi Stephens, 1970, known from Panama and Costa Rica, in the posterior extent of the infraorbitals, details of head spination, and unique COI sequences. The description of Acanthemblemaria johnsonsi Almany & Baldwin, 1996, heretofore known only from Tobago, is expanded based on specimens from islands offshore of eastern Venezuela.

A New Species

A new species of water mites from Montenegro and Bulgaria, Atractides anae Pešić sp. nov., is described, combining traditional morphological techniques with the analysis of partial mtDNA COI sequences (DNA-barcodes). Based on our molecular and morphological analysis, the new species is most closely related to the crenobiontic A. pennatus (K. Viets 1920) from which it differs by 6.4 (SD = 1.12)% K2P distance. A dataset including the novel COI sequences of 10 Atractides species from Montenegro and Iran is assembled in order to facilitate further studies on the genus by using molecular tools.

A New Species

The bibliography of a hitherto inaccurately described anonymous eighteenth-century popular German work on natural history is given, dealing with mammals, birds, fishes, amphibians and reptiles. As an addendum to this work the publisher has given an engraving of an unknown fish from the river Lech, river system of the Upper Danube. The fish could be identified as the cyprinid Leuciscus meidingeri Heckel, 1852. The observation of the species was made 66 years before its recognition as a new species by Heckel.
