Etymology: Hypancistrus: Greek, hypo = under + Greek, agkistron = hook (Ref. 45335); yudja: Named after the Yudjá (also known as Juruna), a group of indigenous people from the Volta Grande do Xingu; in Tupi language, Yudjá means 'the river owners'.

简单描述
检索表 | 型态特徵 | 形态测量图
背棘 (总数) : 2; 背的软条 (总数) : 7; 臀棘: 1; 臀鳍软条: 3 - 4. This species is distinguished from its congeners by its unique color pattern consisting of body with a light tan background and relatively large brown blotches and saddles (Ref. 133100).
Cross section: angular.
This species inhabits the deep portions of the rio Xingu channel and was only found hidden in lateritic conglomerates below 15 m of depth; specimens were collected individually by hand during diving sessions. Specimens kept in captivity were observed to be fairly shy, remains secluded in caves for most of the day. Expert aquarium hobbyists have successfully bred this species with the female laying around 15-20 eggs in a cave that is protected by the male. The fry grows slowly in captivity, usually taking two years or more to reach maturity. Under prime conditions they will reach 4-5 cm TL in about a year.
