Parancistrus nudiventris • Loricariidae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	**Parancistrus nudiventris** Rapp Py-Daniel & Zuanon, 2005
Common Name(s)	LDA004, L031, L176, L300, Peppermint Pleco
Type Locality	Rio Xingu, bedrock at Ilha do Bacabal, Brazil; Pará State; 3°23'19''S, 51°43'24''W
Pronunciation	parr an SIS truss - new dee ven triss
Etymology	(Greek)Para=The side of + (Greek)agkistron=hook. The name nudiventris is derived from the Latin nudus, naked, and ventris, belly.
Species Information
Size	175mm (6.9") SL. Find near, nearer or same sized spp.
Identification	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.
Habitat Information
Distribution	Only occurrences recorded are from Rio Xingú. Amazon, Lower Amazon, Xingu (click on these areas to find other species found there) (Click the map-icon to show/hide map of species distribution)
Temperature	26.0-29.0°C or 78.8-84.2°F (Show others within this range)
Husbandry Information
Feeding	Feeds mainly on algae by browsing the periphyton. Stomach analysis also indicates insect larvae as part of the diet. The intestine is long, typical for mainly algae-based diet.
Furniture	Per the original description Parancistrus nudiventris is a rheophilic species, found in rocky-bottom areas subjected to moderate to strong current. Specimens were found individually or in pairs in shelters under boulders or in narrow cracks on submerged rocks up to 2 meters deep. Young specimens (up to 5 cm SL) were observed under flat rocks over the bottom, usually sharing the shelter with specimens of Baryancistrus spp., Oligancistrus sp., O. punctatissimus, Hopliancistrus tricornis, Ancistrus sp., A. ranunculus, Peckoltia vittata and Pseudancistrus aff. barbatus.
Breeding	Unreported.
