Trichomycteridae is a

life monsefuano (Trichomycterus punctulatus) which was important to the Moche culture and still an important part of Peruvian cuisine.[2]

This family is prohibited from being imported into various parts of the United States.[3]

Taxonomy

The Trichomycteridae comprise about 42 genera and 286 species described.[4] It is the second-most diverse family of the superfamily Loricarioidea.[5] Numerous species still remain undescribed.[5]

The

Trichogeninae are sister groups to each other, and together they form a clade that is sister to the rest of the Trichomycteridae.[7]

Subfamilies and genera include:[1]

Distribution

Trichomycteridae has the greatest distribution of any catfish family.

Neotropics.[9] These fish originate from freshwater in Costa Rica, Panama, and throughout South America.[10] The family extends from Panama southward to Chile and Argentina.[8]

Description

The bodies of these fish are normally naked and elongated. The chin barbels are usually absent, nasal

adipose fin, and some also lack pelvic fins.[10]

Many trichomycterids are small enough to be considered "miniatiurized" (do not exceed 2.6 cm (1.0 in) SL). Miniaturization occurs in many of the trichomycterid subfamilies, including Trichomycterinae, Glanapteryginae, Vandelliinae (in Paravandellia), Tridentinae, and Sarcoglanidinae. Miniaturization has probably occurred four times in trichomycterid evolution, as the Glanapteryginae and Sarcoglanidinae are closely related and may have a single miniaturized ancestor.[5][11]

Ecology

Though the family is commonly known as "parasitic catfishes", Trichomycteridae may actually include the widest range of trophic adaptations within any single catfish family.

necrophagy (carrion) in others, and partial algivory (algae) in Copiondontinae.[9]

Trichomycteridae include species that are active swimmers (Copionodontinae and Trichogeninae), torrent dwellers (Trichomycterinae), litter leaf dwellers (Ituglanis), and sand dwellers (Glanapteryginae and Sarcoglanidinae).

hypogean species. Such species include Ituglanis bambui, I. epikarsticus, I. passensis, I. ramiroi, and Silvinichthys bortayro.[12] Six of the hypogean species are of the genus Trichomycterus: Trichomycterus chaberti, T. itacarambiensis, T. santanderensis, T. spelaeus, and T. uisae.[13]
