“…Remarks: Specimens from several literature sources cited by Eigenmann (1922b: 69) from Panama, including about 150 specimens of Plecostomus plecostomus mentioned by Meek & Hildebrand (1916: 247) should be considered as part of the syntype series of Plecostomus plecostomus panamensis, but only those listed above appear to have been examined by Eigenmann.

Worthington, 1933, but has been treated as a valid species of Clariallabes by Teugels. Acrochordonichthys melanogaster Bleeker, 1854, is designated as type species of Acrochordonichthys Bleeker, 1857, inasmuch as no earlier valid designation has been found. A new genus Pseudobagarius, is proposed for the "pseudobagarius group" of species formerly placed in Akysis. The status of 228 species group names remains unresolved and 31 names based on otoliths ascribed to catfishes are listed but not placed into the checklist. The current emphasis given to catfish taxonomy at present is likely to result in a dramatic increase in the total number of valid taxa as well as major changes in the membership of some of the higher level taxa recognized here.

“…deep waters, rapids); only two specimens have been collected so far. The Ventuari River is one of the most diverse in Venezuela, with 470 species recognized until 2006 (Montaña et al 2006), and at least four new species of catfishes described between (DoNascimiento & Lundberg 2005Werneke et al 2005;Armbruster et al 2007). Six Crenicichla species have been reported for the Ventuari River; but further taxonomic studies are needed to clarify the taxonomy of other species of Crenicichla that are currently unidentified.…”

We describe a new species of the genus Crenicichla Heckel, 1840, from the Ventuari River, a tributary of the Orinoco River in southern Venezuela. Crenicichla zebrina is distinguished from all other species in the genus by its unique coloration pattern, including the combination of a large, dark, vertically oriented, more or less oval-shaped humeral spot, and thin, dark bars, separated by narrow, vertical, yellowish bars extending between the dorsal and anal fin base on the caudal half of the body. Crenicichla zebrina is included in the putative C. acutirostris group (9 species) and represents the only species in the group known to date from the Orinoco basin.

Titulo en ingles: Fisheries aspects and reproductive biology of Hemiancistrus guahiborum, in a scree in the Bita river, Puerto Carreño - ColombiaTitulo en portugues: Aspectos pesqueiros e biologia reproductiva de Hemiancistrus guahiborum, num pedregal do rio Bita, Puerto Carreño - ColombiaResumen: En el pedregal El Alizal del río Bita en Puerto Carreño, Vichada, se estudio la pesquería y la biología reproductiva de la especie Hemiancistrus guahiborum Para lo cual se definió la unidad económica de pesca (UEP) y se calcularon los parámetros de esfuerzo y captura Igualmente se estimó la densidad de peces en el pedregal y su patrón de distribución mediante el método de la cuadrícula A partir de la determinación del sexo y estado de madurez gonadal de ejemplares capturados mensualmente, se estableció la época de reproducción y se estimaron el factor de condición total (K) y el factor de condición somático (K’), el índice gonadosomático, la fecundidad absoluta (F) y relativa a peso y la talla media de maduración sexual (L50%) La UEP la constituye un pescador y su careta, con capturas por unidad de esfuerzo de 28 ±18 ejemplares por faena, en faenas de 52 ± 20 min La densidad media fue de 0 06 ejemplares / m2, con una relación varianza / media de 8 86 En todos los meses muestreados se observaron ejemplares maduros y no se presentó variación significativa de los factores de condición K y K’, ni del índice gonadosomático entre meses La F se estableció en 48 ± 19 ovocitos y la fecundidad relativa en5 3 ± 0 3 ovocitos/g La talla L50% de madurez se estimo en 6 4 cm de Longitud Estándar para hembras y en 7 5 cm para machos Se observó cuidado parental del macho Como estrategias de manejo se propone: mantener el período de veda actual, establecer la talla de captura en 6 cm de Longitud Estándar, prohibir el comercio de hembras ovadas, establecer áreas de cría dentro de los pedregales, rotar la pesca de los pedregales e incentivar los procesos de cría en cautiverio de la especie.Palabras clave: cucha roja, densidad, factor de condición, fecundidad, talla media de madurez, unidad económica de pescaAbstract: In the scree El Alizal of the Bita river, Puerto Carreño, Vichada, was studied fisherie and reproductive biology of the species Hemiancistrus guahiborum The fisheries economic unit (FEU) and the parameters of effort and fishing were calculated Likewise, the fish density in the scree and its distribution pattern were determined using the grid method By observing the gender and gonadal mature status of monthly caught samples, the breeding season was determined and the total condition factor (K) and the somatic condition factor (K’), the gonadosomatic index, the absolute fecundity (F) and relative fecundity at weight and the mean size of sexual maturity (L50%) were calculated The FEU was composed by a fisherman and its mask, who using lung freediving, captured 28 ± 18 individuals / fishing,in fishing tasks that lasted 52 ± 20 min The mean density in the scree river was 0 06 individuals /m2 with a relation variance /mean of 8 86 Mature individuals were observed in all sampled months Not significant variation in the condition factor (K and K’) either gonadosomatic index between months was observed The F was established in 48 ± 19 oocytes and the relative fecundity was 5 3 ± 0 3 oocytes / g The maturity size L50% was determined in 6 4 cm and 7 5 cm standard length for females and males, respectively Parental care in nest was observed in the males As management strategies are suggested the follows: keep the period of current fishing ban, establish the fishing size in 6 cm SL, ban the trade of mature females, establish breeding areas in the scree rotate the fishing in the scree river and stimulate the captive breeding of the species.Keywords: condition factor,density, fecundity,fishing economic unit, mean size of maturity, red cuchaResumo: No calhaus El Alizal do rio Bita em Puerto Carreño, Vichada, foi estudada a pescaria e biología reprodutiva da espécie Hemiancistrus guahiborum Assim, definiou-se a unidade econômica da pesca (UEP) e foram calculados os parâmetros de esforço e captura Também estimou-se a densidade de peixes e seu padrão de distribuição pelo método de quadrícula Com base na determinação do sexo e estádio de maturação gonadal dos peixes capturados mensalmente, estabeleceu-se a época de reprodução e foi estimado o fator de condição total (K) e fator de condição somáticas (K ‘), o índice gonados somático, a fecundidade absoluta (F) e relativa ao peso e tamanho médio de maturação sexual (L50%) A UEP é constituida por um pescador e sua máscara de mergulho, com captura por unidade de esforço de 28 ± 18 exemplares em periodos de 52 ± 20 min A densidade média foi de 0,06 exemplares / m2, com uma proporção variançã /média de 8 86 Em todos os meses de amostragem foram observados adultos maturos e não mostraram variação significativa dos factores de condições K e K ‘, nim do índice gonadossomático entre os meses A F foi de 48 ± 19 ovócitos e a fecundidade relativa em 5 3 ± 0 3 ovócitos / g O tamaño medio de maduração L50% foi estimada em 6 4 cm de comprimento padrão para as femias e 7 cm para os machos Foi observado cuidado parental dos machos Como estratégia de manejo pesqueiro é proposto: manter o período de proibição atual, estabelecer o tamanho de captura de 6 centímetros de comprimento padrão, proibir o comercio de fêmeas ovadas, estabelecer áreas de reprodução dentro dos calhaus, rotar a pesca dos calhaus e começar processos de reprodução em cativeiro da espéciePalavras chaves:cascudo vermelho, comprimento médio de maduração, densidade, fator de condição, fecundidade, unidade econômica de pesca
