Microglanis nigrolineatus is described from streams of Bermejo River basin, northwestern Argentina. It is distinguished from all congeners by a combination of characters including a unique colouration pattern: a thin dark line that runs along middle body from vertical line through dorsal-fin origin to end of adipose fin, delimiting two dark-brown areas ending in a dark blotch crossing entire body depth just anterior to caudal-fin origin and dorsal region of head uniformly dark, lacking a paler area on nuchal region. Also, thorn serrae on anterior margin of pectoral-fin spine are short. All known specimens of M. nigrolineatus were collected in the upper Bermejo River basin, in the province of Salta, Argentina. The upper Bermejo River basin extends to the prov-ince of Jujuy, in Argentina, and southern Bolivia. Considering the relatively wide known distribution of this species in the upper Bermejo River basin in Argentina, close to the limit with Bolivia, M. nigrolineatus is most probably present also in that country (Terán et al 2016). Aquarium Care: Microglanis nigrolineatus is one of twenty five, small to medium sized pims, found in this family, and as such is a good addition to the medium sized community tank, and will not harm the occupants unless they are small enough to fit into its mouth such as newly born fry and young fish. If you keep livebearers such as Guppies and Platies in with them you will very rarely be overrun with fry as this Bumblebee Catfish will promptly finish them off on its night time prowls. Hiding places such as rockwork, plants and or wood will benefit this species and help, along with regular water changes, to keep this it happy in its surroundings. Diet: Can be fed a varied diet of tablet food, pellets, worm foods and frozen food such as bloodworm. Etymology: The specific name nigrolineatus: is formed by two Latin adjectives niger: black and lineatus: with lines; in allusion to the dark stripes running along trunk of the new species. An Adjective. |

IUCN Red List |
This species is considered Vulnerable according to the criteria B1ab(iii); D2. It has an extent of occurrence (EOO) of 6,666 km2. This species inhabits in an area highly impacted by agriculture, deforestation and human activities. There are two locations and a continuing decline inferred in the area, extent and quality of habitat based on these threats. In particular, contamination for industries is considered severe enough to push the species to becoming Critically Endangered or Extinct in a very short time period, (IUCN 2020). |
