Species Information
Size	175mm or 6.9" SL. Find near, nearer or same sized spp.
Identification	Parancistrus is distinguished by having a membranous connection between the dorsal and adipose fins, a large gill opening, and its cephalic and body scutes are not keeled. Additionally, nuptial males have fleshy folds along the dorsal-fin base. Other genera with a membrane connecting the dorsal and adipose fins include Baryancistrus, Oligancistrus, and Spectracanthicus. Parancistrus differs from these genera by the large gill openings. Initially known as the l-number L031 (collected at Altamira on the Rio Xingú). Parancistrus nudiventris is distinguished from P. aurantiacus (the only other valid species of Parancistrus) by the lack of abdominal plates, larger interbranchial distance (39-56% in HL vs. 24.9-39.5% in P. aurantiacus), narrower interorbital distance (26.8-38% in HL vs. 38.5-43.1% in P. aurantiacus), buccal teeth more conspicuous, and shorter posterior dentary processes.
Sexing	Heavy odontodal growth on cheeks, pectoral spines and body plates on mature males. Much less or non-existent on mature females. Additionally, nuptial males have fleshy folds along the dorsal-fin base.
