|Scientific Name||Lasiancistrus sp. (L033) , 1989|
|Common Names||L033, Plettet Halvfinnesugemalle
Spotted Half Fin Pleco
|Type Locality||Brazil: Rio Araguaia, Pará State|
|Pronunciation||LASS ee an SISS truss|
|Etymology||Greek, lasios, -a, -on = hairy + Greek, agkistron = hook|
|Size||120mm or 4.7" 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.
Similar to L178 but with larger, more widely spaced white spots. In mature individuals the lower half of the dorsal fin is dark red. This feature is also exhibited by L178, which originates from the Tocantins (into which the Araguaia flows). Not all L033 exhibit the red in the dorsal fin.
|Sexing||Snout of nuptial males almost square (vs. rounded in females and juveniles). Adult males of most species (except Lasiancistrus tentaculatus) with whisker-like odontodes at anterolateral corner of snout; males of L. tentaculatus have tentacules instead of whisker-like odontodes along anterior margin of snout. Nuptial males have tentacules longer than their associated odontodes on the pectoral-fin spine.|
