Taxonomy
editLoricaria was the first genus of the family Loricariidae described.[1] Thus, it is the nominal genus of the family Loricariidae.[2] Phylogenetic relationships within Loricaria and among other members of Loricariini remain uncertain. Its external morphology shows few shared derived characters, making comparison with other genera difficult. Loricaria has been hypothesized to occupy a basal position among members of the subtribe Loricariina, with the other genera possessing derived characters. Based on the characteristics of its mouth, Loricaria appears to maintain a close relationship with representatives of the Pseudohemiodon group.[2] Proloricaria is considered a synonym of Loricaria.[2]

Distribution and habitat
editThis genus is distributed east of the Andes in nearly the entire tropical and subtropical parts of South America. Species occur in a variety of habitats from the main flow of rivers on sandy and rocky bottoms to flooded areas and lakes over muddy and sandy bottoms.[2]
Description
editLoricaria species are recognized by the presence of elongate, slender filaments on the lips and a low number of bicuspid premaxillary teeth (usually three to four per side) that are about twice the length of the dentary teeth.[1]
Sexual dimorphism includes hypertrophied development of the pectoral fin spines, blunt odontodes on the pelvic and anal fin spines, and tooth crowns becoming shortened and rounded in mature males.[2]
For the four species characterized, karyotypic diversity ranges from 2n = 62 to 2n = 68.[2]
Ecology
editThe site of egg deposition varies between different members of the genus. In some species, eggs are carried on the enlarged lower lip of the male. L. piracicabae has its egg adherent to its ventral surface.[9] Males are abdomino-lip brooders.[2]
