All Fishes Data Sheet
Scientific Name	**Lasiancistrus volcanensis** Dahl, 1941
Common Names	LDA071, Sage Halffin Pleco L312, Salvie-halvfinnesugemalle (Denmark)
Type Locality	Río Volcán near its junction to Río San Bartolomé, tributary of Río Magdalena, Antióquia Dept., Colombia, elevation about 600 meters.
Pronunciation	LASS ee an SISS truss
Etymology	Greek, lasios, -a, -on = hairy + Greek, agkistron = hook
Species Information
Size	100mm or 3.9" SL. Find near, nearer or same sized spp.
Identification	Adult Lasiancistrus can be separated from all other loricariids by the presence of whisker-like odontodes on the cheeks. In addition, they have evertible cheek odontodes; three rows of plates on the caudal peduncle; and a modified, bar-shaped opercle. The caudal fin is slightly emarginate to forked, with the lower lobe longer than upper. Nuptial males have tentacules on the pectoral-fin spines longer than their associated odontodes; and transluscent tentacules on the snout that have odontodes associated with them. Nuptial males lack hypertrophied odontodes on top of the head and lack long, bristle-like odontodes on the leading edge of the pectoral-fin spine. This fish is collected in faster flowing tributaries of the upper Rio Magdalena, Colombia and exported through Bogota. It normally appears as bycatch in shipments of Colombian Chaetostoma. Further investigation is needed to see if this fish is identifiable with Lasiancistrus caucanus.
Sexing	Unknown
