Relevant Information:

Similar looking to P. gracilis but this species has an enlarged upper tail lobe. Dorsal and pectoral fins are poisonous. This genus has been in confusion for a good number of years now especially with another close member of the Pimelodidae family, Pimelodus. These notes are the following distinguishing characteristics from the two genus. These notes are the following distinguishing characteristics from the two genus. Pimelodella: Adipose fin long, low with a curved margin. The humeral process is long and spiky. Body usually plain with a dark lateral stripe; rather depressed body. Pimelodus:Adipose fin short, high, with a straight or sloping margin. Humeral process broad, triangular. Body variously patterned, usually quite deep, like the African genera Synodontis. Aquarium Care: Treat as you would do with any member of the Pimelodus in that they will be predatory on small fishes in the aquarium and it is also better to keep them in small groups rather than singularly, as this will dilute the aggression. Diet: Will eat any aquarium prepared foods such as tablets, pellets, frozen and live foods. Not fussy eaters. Etymology: The specific name lateristriga: lateralis (L.), of the side; striga (L.), furrow or groove (i.e., streak), referring to blue-silver longitudinal stripe on sides.

IUCN Red List

The genus Pimelodella is taxonomically confusing, with several morphotypes that are difficult to recognize. The last taxonomic revision of the genus (Eigenmann, 1917) lists five species for the state of Rio de Janeiro. In this revision, the author points out that there is variation in a number of characteristics among the species, which raises doubts about their precise identification in the Paraíba do Sul river basin and coastal rivers, from southern Rio de Janeiro to the São Francisco river (inclusive). Due to the aforementioned taxonomic problems, Pimelodella lateristriga was listed as Data Deficient (DD), (IUCN 2022).
