Loricaria coximensis Rodriguez, Cavallaro & Thomas 2012

Distinguished from all other congeners except Loricaria holmbergi, Loricaria lundbergi, Loricaria parnahybae, and Loricaria pumila by having abdominal plates confined to the pre-anal shield and posterior median abdominal area, usually loosely joined or separated by naked areas, pectoral girdle mostly naked, with isolated plates near base of pectoral fins and posterior to gill opening (vs. abdominal plates well developed and tightly arranged across the entire median abdominal area, including the pectoral girdle). Differs from these other four species by meristic counts and several morphometric proportions, particularly a broader head, 19.4-21.3% SL (vs. 14.1-19.1% SL) (Ref. 90156).

Gut contents of one specimen contain only seeds which conforms with previous observations of granivory in other species of Loricaria (Ref. 90156).

Loricaria coximensis is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the basin of the Coxim River, for which it is named, near the municipality of São Gabriel do Oeste in the state of Mato Grosso do Sul in Brazil. The gut contents of one individual examined contained only seeds, indicating that the species may be granivorous. The species reaches 9.4 cm (3.7 inches) in standard length and is believed to be a facultative air-breather.
