A New Species of Ammoglanis (Siluriformes: Trichomycteridae) from Venezuela
~ 255 Ichthyol. Explor. Freshwaters, Vol. 11, No.3, pp. 255-264,6 figs., 1 tab., November 2000 @2000byVerlagDr. Friedrich Pfeil, MiincheD, Germany - ISSN 0936-9902 A new species of Ammoglanis (Siluriformes: Trichomycteridae) from Venezuela Mario c. C. de Pinna* and Kirk O. Winemiller** A new miniaturized species of the trichomycterid genus Ammoglanisis described from the Rio Orinoco basin in Venezuela. It is distinguished from its only congener, A. diaphanus,by: a banded color pattern formed by internal chromatophores; 5 or 6 pectoral-fin rays (7 in A. diaphanus),5/5 principal caudal-fin rays (6/6 in A. diaphanus),ii+6 dorsal-fin rays (iii+6+i in A. diaphanus),30 or 31 vertebrae (33 in A. diaphanus),six or seven branchiostegal rays (five in A. diaphanus),subterminal mouth (inferior in A. diaphanus)and by the lack of premaxillary and dentary teeth. The two speciesalso differ markedly in a number of internal anatomical traits. Synapomorphies are offered to support the monophyly of the two species now included in Ammoglanis,as well as autapomorphies for each of them. Ammoglanispulex is among the smallest known vertebrates, the largest known specimen being 14.9 mm SL. It is a fossorial inhabitant of shallow sandy sections of clear- and light blackwater streams, and probably feeds on interstitial microinvertebrates.

Neotropical Ichthyology, 2(2):61-74, 2004 Copyright © 2004 Sociedade Brasileira de Ictiologia Trichomycterus maracaya, a new catfish from the upper rio Paraná, southeastern Brazil (Siluriformes: Trichomycteridae), with notes on the T. brasiliensis species-complex Flávio A. Bockmann* and Ivan Sazima** Trichomycterus maracaya, a new species of Trichomycteridae, is described from a streamlet in the upper rio Paraná, Poços de Caldas, State of Minas Gerais, southeastern Brazil. The following putative autapomorphies distinguishes T. maracaya from congeneric species: 1) row of lateral blotches not forming a stripe at any phase during ontogeny; 2) superficial layer of pigmentation of juveniles and large (presumably adults) specimens consisting solely of scattered chromatophores. Furthermore, the new species is characterized by a combination of yellow ground color in life and mottled pattern formed by small to medium-sized, brown, irregularly-coalescent, well-defined deeper-lying blotches, and more superficial dots on the body. Trichomycterus maracaya is assigned to the T. brasiliensis species-complex (which includes T. brasiliensis, T. iheringi, T. mimonha, T. potschi, T. vermiculatus, and several undescribed species apparently endemic to the main river basins draining the Brazilian Shield) based on the presence of: 1) blotches in four longitudinal rows of deeper-lying pigmentation on the trunk large, horizontally-elongated, and well-defined; 2) pectoral fin with I+5-6 rays; 3) separation between the anterior and posterior cranial fontanels by the primordial epiphyseal cartilaginous bar being present only in larger specimens; and 4) pelvic-fin bases very close to each other, sometimes in contact. Trichomycterus maracaya, uma espécie nova de Trichomycteridae, é descrita de exemplares obtidos num riacho do alto rio Paraná, Poços de Caldas, Estado de Minas Gerais, sudeste do Brasil. -
A New Species of the Neotropical Catfish Genus Trichomycterus (Siluriformes: Trichomycteridae) Representing a New Body Shape for the Family
Copeia 2008, No. 2, 273–278 A New Species of the Neotropical Catfish Genus Trichomycterus (Siluriformes: Trichomycteridae) Representing a New Body Shape for the Family Wolmar Benjamin Wosiacki1 and Ma´rio de Pinna2 Trichomycterus crassicaudatus is described as a new species from the Rio Iguac¸u basin in southern Brazil. The new species has an exceptionally deep posterior region of the body (caudal peduncle depth 22.8–25.4% SL), resulting in an overall shape which distinguishes it at once from all other members of the Trichomycteridae. The caudal fin of the species is broad-based and forked, a shape also distinguishing it from all other species in the family. A number of autapomorphic modifications of T. crassicaudatus are associated with the deepening of the caudal region, including an elongation of the hemal and neural spines of the vertebrae at the middle of the caudal peduncle. Phylogenetic relationships of the new species are yet unresolved, but it shares a similar color pattern and a thickening of caudal-fin procurrent rays with T. stawiarski, a poorly-known species also from the Rio Iguac¸u basin. Coloration and body shape also include similarities with T. lewi from Venezuela. HE genus Trichomycterus is the largest in the the ninth species of Trichomycterus recorded for the Rio family Trichomycteridae, with approximately 100 Iguac¸u Basin above the Iguac¸u waterfalls (the others being T. T nominal species and probably numerous others stawiarski, T. castroi, T. naipi, T. papilliferus, T. mboycy, T. still undescribed. The genus is not demonstrably a mono- taroba, T. plumbeus, and T. -

São Paulo, SP, Brasil. ORCID: http://orcid.org/0000-0003-1711-4816. E-mail: [email protected] Abstract. Two new species of particular biogeographic significance are described from the upper rio Paraguay basin, one of the genus Paracanthopoma (Trichomycteridae, Vandelliinae) and the other of the genus Ernstichthys (Aspredinidae, Hoplomyzontinae). The two species occur sympatrically in the Rio Taquarizinho, tributary of the Rio Taquari, in the upper Paraguay system. Paracanthopoma saci is distinguished from its only congener, P. parva, by a spatulate caudal peduncle; a minuscule premaxillary dentition (reduced to three delicate teeth); the supraorbital latero-sensory canals opening as two separate s6 pores; the caudal fin slightly convex or truncate with round edges; the skull roof entirely open, unossified; the origins of dorsal and anal fins approximately at same vertical; and the pelvic fin with three rays. Ernstichthys taquari is diagnosed among congeners by the narrow bony shields on dorsal and ventral series, not overlapping or contacting each other; by the presence of seven or eight serrations on the posterior margin of the pectoral spine; and by the pectoral-fin spine only slightly larger than subsequent soft rays. Both Paracanthopoma and Ernstichthys were previously unknown outside of the Greater Amazonian river systems (Amazon, Orinoco, Essequibo and smaller surrounding drainages). -

E-mail: [email protected] 1 ABSTRACT Burrowing habits or complex environments have been generally considered as potential drivers acting on appendicular skeleton reduction and loss among vertebrates. Herein we suggest that this may be the case for lissamphibians and squamates, but that fin loss in fishes is usually prevented due to important structural constraints, as pectoral fins are commonly used to control rolling and pitching. -
Teleostei: Siluriformes) Inferred from Ultraconserved Elements Luz E
www.nature.com/scientificreports OPEN Phylogenomic analysis of trichomycterid catfshes (Teleostei: Siluriformes) inferred from ultraconserved elements Luz E. Ochoa 1,2*, Aléssio Datovo2, Carlos DoNascimiento 3, Fabio F. Roxo1, Mark H. Sabaj4, Jonathan Chang5, Bruno F. Melo1, Gabriel S. C. Silva1, Fausto Foresti1, Michael Alfaro5 & Claudio Oliveira1 The family Trichomycteridae is one of the most diverse groups of freshwater catfshes in South and Central America with eight subfamilies, 41 genera and more than 300 valid species. Its members are widely distributed throughout South America, reaching Costa Rica in Central America and are recognized by extraordinary anatomical specializations and trophic diversity. In order to assess the phylogenetic relationships of Trichomycteridae, we collected sequence data from ultraconserved elements (UCEs) of the genome from 141 specimens of Trichomycteridae and 12 outgroup species. We used a concatenated matrix to assess the phylogenetic relationships by Bayesian inference (BI) and maximum likelihood (ML) searches and a coalescent analysis of species trees. The results show a highly resolved phylogeny with broad agreement among the three distinct analyses, providing overwhelming support for the monophyletic status of subfamily Trichomycterinae including Ituglanis and Scleronema. Previous relationship hypotheses among subfamilies are strongly corroborated, such as the sister relationship between Copionodontinae and Trichogeninae forming a sister clade to the remaining trichomycterids and the intrafamilial clade TSVSG (Tridentinae-Stegophilinae-Vandelliinae- Sarcoglanidinae-Glanapteryginae). Monophyly of Glanapteryginae and Sarcoglanidinae was not supported and the enigmatic Potamoglanis is placed outside Tridentinae. Unraveling the relationships of major sections of the Tree of Life is one of the most daunting challenges of the evolutionary biology. Massively parallel DNA sequencing (so-called Next-gen sequencing) is a promising tool that is helping to resolve the interrelationships of longstanding problematic taxa1–4.
