Loricaria is a genusofcatfishes (order Siluriformes) of the family Loricariidae.
Loricaria 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 synonymofLoricaria.[2]
This genus is distributed east of the Andes on nearly the entire subcontinent. 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]
Loricaria 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]
The site of egg deposition varies; L. curvispina places its eggs over flat rocks in rapids.[3] In some species, eggs are carried on the enlarged lower lip of the male. L. piracicabae has its egg adherent to its ventral surface.[3] Males are abdomino-lip brooders.[2]
