“…The genus is recognized by its long and slender body and variably pronounced rostrum, and by its brown overall coloration with two longitudinal stripes extending from the tip of the rostrum to the caudal peduncle. The species allocated in this genus are broadly distributed in freshwater streams and rivers of the Amazon, Orinoco, Maracaibo, Paraná and coastal drainages of the Guiana shield (Covain & Fisch-Muller, 2007), being recently recorded for the Magdalena-Cauca system (Ballen & Mojica, 2014).…”

A new species of Farlowella (Siluriformes: Loricariidae) of the F. nattereri species-group from the rio Xingu basin, Mato Grosso, Brazil, with comments on Farlowella jauruensis , a poorly-known species from the upper rio Paraguai basin

A new species of Farlowella is described from eighteen specimens collected in the upper rio Xingu basin, Mato Grosso State, Brazil. The new species is a member of the Farlowella nattereri species-group and can be distinguished from other members of the group, with exception of Farlowella jauruensis, by exhibiting a proportionally shorter snout. The new species is distinguished from F. jauruensis by differences on the cleithrum and plate morphology, by counts of pelvic and caudal-fin rays, and by the color pattern of the snout. The discovery of new lots of F. jauruensis, a species so far known only from the holotype, is also herein reported. This discovery represents a considerable expansion of the geographic distribution and of the number of known specimens of F. jauruensis. Uma nova espécie de Farlowella é descrita de dezoito espécimes da bacia do alto rio Xingu, estado do Mato Grosso, Brasil. A nova espécie é membro do grupo de espécies da Farlowella nattereri, e é diagnosticada de outros membros deste grupo, com exceção de Farlowella jauruensis, por apresentar um focinho proporcionalmente mais curto. A nova espécie se diferencia de F. jauruensis por diferenças morfológicas do cleitro e de placas, pelas contagens de raios da nadadeira pélvica e caudal, e pelo padrão de colorido do focinho. A descoberta de novos lotes de F. jauruensis, uma espécie até então conhecida apenas pelo holótipo, também é aqui reportada. Esta descoberta representa uma expansão considerável da distribuição geográfica e do número de espécimes conhecidos de F. jauruensis.

“…Its species are easily recognized by the long and slender body, variably pronounced rostrum, and the dorsal-fin insertion set nearly halfway between the head and the tail (Covain, Fisch-Muller, 2007). Farlowella is widely distributed in the main cis-Andean South American River drainages (Orinoco, Amazon, and La Plata) and species of the genus are also found in the trans-Andean Maracaibo and Magdalena River basins (Ballen, Mojica, 2014). Retzer, Page (1996) proposed six distinct species groups of Farlowella (viz., the F. acus, F. amazonum, F. curtirostra, F. knerii, F. mariaelenae, and F. nattereri species groups).…”

A new species of Farlowella is described from the Bermejo River basin, in Salta and Jujuy provinces, northwestern Argentina. The new species belongs to the Farlowella nattereri species group. The new species is diagnosed by the following combination of characters: marbled rostrum, five rows of lateral plates series, relatively short snout (snout-mouth length less than 50.0% of head length), complete half-moon shaped spot on caudal fin, and short predorsal distance (37.8-41.8% of standard length).

Dermal modifications of the red lionfish, Pterois volitans

2020

View full text Add to dashboard Cite

Vertebrates have evolved flexible and hard dermal armor, but there is often a tradeoff between mobility and protection. Skeletal modifications include fish scales, the shells of tortoises and turtles, and the cranial projections that are found in marine iguanas and lionfish. Sexual dimorphisms of cranial structures are prominent in fishes; we hypothesized that cranial projections of Pterois volitans will change over ontogeny and are sexually dimorphic. The goal of this study is to quantify differences in the cranial armor of P. volitans over a range of sizes (juveniles to adults) to understand allometric growth and possible sexual dimorphisms using specimens from invaded ranges. We found no difference in the total number of cranial spines between sexes, suggesting that the number of cranial spines is not a sexually dimorphic trait in P. volitans. We found positive allometry for total cranial spine number, and length and width of the three largest cranial spines, with respect to the fish total length. Here, we also document another skeletal modification in P. volitans, which is the addition of spines on the caudal fin. Overall, these data show that P. volitans' develop robust dermal modifications as they grow larger, and we suggest that phenotypic plasticity of this species should be explored in their native and invaded ranges.
