Relevant Information:

Description: In adults Loricaria birindellii is distinguished from all other nominal species of Loricaria by having a combination of an elongate dorsal-fin spine (36.0% SL based on the holotype vs. 16–29%, usually less than 26% SL) that is supported throughout most of its length by the first branched ray and an inconspicuous (vs. prominent) post-orbital notch with minimum orbital diameter 95.4–97.2% (vs. 71.8–91.5%) of maximum orbital diameter. It is further distinguished from similar and geographically proximate species, L. lata and L. simillima, by having a narrower head width (13.9–14.9% SL vs. 15.2–19.4% SL in L. simillima and 16.4–20.1% SL in L. lata), from L. clavipinna by having more divergent plates (21 vs. 18–19) and fewer coalesced plates (13 vs. 15–16) in the lateral series, and from L. cataphractta by having weakly (vs. strongly) developed odontode crests on head and dorsal trunk plates, more divergent plates (21 vs. 17–20, usually 19) and fewer coalesced plates (13 vs. 13–17, usually 15–16) in the lateral series. Etymology: The specific name birindellii: In honour of Brazilian ichthyologist José Luís O. Birindelli (b. 1979), Universidade de São Paulo, who helped collect type material and “deftly commanded” the 2007 Pipe Expedition to Serra do Cachimbo, Brazil, leading to the discovery of this and many other undescribed fishes. Remarks: The authors (Thomas, M.R. and M.H. Sabaj Pérez 2010) caught this new species downstream of a cataract in clear water approximately one to two metres deep and with a moderate current. The substrate was predominantly sand with patches of bedrock and large lateritic boulders.

IUCN Red List

Loricaria birindellii is endemic to Brazil, specifically the Xingu River basin in the state of Pará, occurring in rapids with rocky and pebble bottoms. Although the construction of the Belo Monte hydroelectric dam altered part of its natural environment, a possible population decline is suspected not to represent a threat to the species due to its wide distribution in the basin. For this reason, Loricaria birindellii has been categorised as Least Concern (IUCN 2022).
