5-476: Ancistrini is a tribe of catfishes of the family Loricariidae . Most are restricted to tropical and subtropical South America , but there are also several genus ( Ancistrus , Chaetostoma , Hemiancistrus and Lasiancistrus ) in southern Central America . Ancistrini have previously been considered a loricariid subfamily . However, the subfamily Hypostominae would be paraphyletic if Ancistrinae continued to be recognized. To continue recognizing
10-484: The monophyly of this group while returning it to Hypostominae, Hypostominae was broken into several tribes. Pterygoplichthyini is sister to the tribe Ancistrini, which shares the derived presence of an evertible patch of plates on the cheek. Most Ancistrini species (except for some Pseudancistrus and Spectracanthicus ) can be separated from all other loricariids except the Pterygoplichthyini by
15-447: The name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae . The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology , the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the genus name Pseudomonas . An unfamiliar taxonomic rank cannot necessarily be identified as
20-461: The presence of evertible cheek plates with hypertrophied odontodes . This article relating to Hypostominae is a stub . You can help Misplaced Pages by expanding it . Tribe (biology) In biology , a tribe is a taxonomic rank above genus , but below family and subfamily . It is sometimes subdivided into subtribes . By convention, all taxa ranked above species are capitalized, including both tribe and subtribe. In zoology ,
25-410: The standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany , the standard ending for
