A New Species

Platybaetis bishopi Müller-Liebenau, 1980 was originally described from Malaysia only at the larval stage. We provide the first description of the imaginal stage of P. bishopi based on materials from Thailand. The imago of this species can be separated from the known species by coloration of abdominal terga and coloration of wings. A new species, Platybaetis nayokensis sp. nov., is described based on male and female imagos and larvae from Thailand. The larva of this species is mainly distinguished by medium acute spines on the posterior margin of the abdominal terga and two apical setae on the glossa, which seem to be shorter than in other species. The imago can be separated by the abdominal color pattern. The larva of this genus is adapted to live on wet rocks projecting out of water; it prefers large stones near small waterfalls or areas between two large rocks in running water.

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.

Stenolicmus ix, new species, is described from Igarapé Curuá, left tributary of the Rio Amazonas, Pará, Brazil. It can be distinguished from S. sarmientoi by the length of the nasal barbels that reach the base of the first opercular odontodes; length of the maxillary barbels that reach the posterior margin of the opercular odontode plate; seven well-developed opercular odontodes; seven well-developed interopercular odontodes; color pattern of the dorsal region of trunk composed of agglomerated chromatophores forming circular patches twice the diameter of the eye; proportionally large eyes, 11.8% HL; caudal peduncle tall, 11.6% SL, without dark bar at base of the caudal fin; length of the head proportionately larger, 17.9% SL; unbranched rays of caudal fin reaching distal margin of fin. Comparisons with other Sarcoglanidinae and Trichomycteridae are presented. Some comments on the systematics and phylogenetic relationships of the group are made.

A New Species

The male and female of a new species of long-horned caddisfly,Nectopsyche paramo, are described from the high Andes of Ecuador. The new species was found above 4,000 m, representing the highest recorded elevation for a species in the genus. The larval stage of the species is also described. Only a total of 13 larvae were collected during a 17-month sampling program and 11 adults, suggesting that the species is rare. Larvae were found mainly in leaf packs. A male and female were observed in a mating swarm ca. 3 m above a stream during late afternoon. In addition, we redescribe the adult male ofNectopsyche spiloma (Ross), previously known from Ecuador from unsubstantiated literature records.

Vietnamella chebalingensis Tong, sp. nov. is described based on larval stage from China. The new species is distinguished from its congeners by the following combination of characters: body purple black with mottled white markings; length of inner pairs of cephalic projection approximately half of the outer pairs; posterior margin of abdominal tergites I–VI and VIII–X each with a pair of pointed projections, but tergite VII bearing only a single projection. The morphological evidence and molecular data (COI, Kimura 2-parameter) support that this new species represents the sixth species of the genus Vietnamella. An identification key to known larvae of the genus Vietnamella is provided.

Chilenoperla puelche n. sp. is described based on male and female adults and one nymph. The wing color pattern and the gen-italia of the adults are diagnostic clearly distinguishing it from the other species of the genus. However, the nymph is similar tothat of C. elongata Vera. This new species is distributed in the Andes Mountains of Chile from 38° to 39° south latitude; Adults were collected in September and November.

A New Species

A new Hemigrammus species is described from tributaries of the igarapé Juruti Grande and rio Arapiuns, lower rio Amazonas, Pará State, Brazil. The new species can be easily diagnosed from all its congeners, except from Hemigrammus stictus (Durbin), by possessing a single, large humeral spot which extends longitudinally from the fifth or sixth to the posterior margin of eighth to tenth, lateral line scales. It can be distinguished from Hemigrammus stictus by possessing a pronounced upper, anteriorly-oriented extension in the humeral blotch, conferring an inverted-comma shape to it, and by displaying a distinct life color pattern.

ABSTRACT A new species of the loricariid genus Pareiorhaphis is described based on specimens from several tributaries of the upper and middle rio Jequitinhonha basin, Minas Gerais State, eastern Brazil. The new species increases the number of known species of Pareiorhaphis to 25 and, at the same time, represents the second member of the subfamily Neoplecostominae reported from the rio Jequitinhonha basin. The new species is diagnosed from all remaining congeners by a putative autapomorphic feature related to the color pattern: a well-defined, dark brown stripe on the median series of lateral plates that extends along the flank from the posterior margin of compound pterotic to the caudal-fin base. The shallow caudal peduncle and the comparatively larger number of dentary teeth also distinguish the new species from most congeners. The new species is also compared to Pareiorhaphis stephanus, a syntopic congener with similar traits.

A New Species

Only three species of Trichomyia Haliday have been recorded in Mexico. Trichomyia cirrata Coquillett, 1902, is recognized by its female characteristics, T. fairchildi Vargas and D az-N jera, 1953, was described based only on the wing and must be considered as species inquirenda, and T. maldonadoi (Vargas, 1953), which was described based on one female specimen. Specimens of Trichomyia collected in the states of Campeche, Yucatan, and Oaxaca, Mexico, allowed this female to be associated with the male of T. brevitarsa (Rapp, 1945), thus providing a first report of this species in Mexico. Consequently, T. maldonadoi is proposed as a synonym of T. brevitarsa. Additionally, a new species of Trichomyia from the state of Veracruz, Mexico, is described and illustrated based on the male and female characteristics.
