Down Cat-eLog Data Sheet
Scientific Name Rhinotocinclus isabelae  Reis & Lehmann A., 2022
Common Names Bumble Bee Otocinclus
Parotocinclus Sp. Peru, Parotocinclus Sp(3)
Type Locality Río Nanay, between Puerto Almendra and Tarapoto, Iquitos, Loreto, Peru, 03°48'15"S, 73°23'53"W.
Etymology Rhinotocinclus is a combination of the Greek Rhinos meaning beak or snout and Otocinclus, a genus of Hypoptopomatinae, in allusion to the conspicuous and elegant snout of most of its species. This species is named in honour of Isabela Alho dos Reis, the younger daughter of Reis, the senior author of the paper in which the species was described. Isabela is an enthusiast of biodiversity conservation and has been interested in aquarium fishes since she was very young.
Down Species Information
Size 20mm or 0.8" SL. Find near, nearer or same sized spp.
Identification Rhinotocinclus is diagnosed from all other genera in Hypoptopomatinae by having the canal cheek plate on the ventral surface of the head posteriorly elongated and contacting the cleithrum (vs. canal cheek plate rounded or mesially elongated and not expanded backwards to contact the pectoral girdle).

It is interesting to note that the colouration of this species is very similar to the young juvenile colouration of L229, a species of Hypostomus also exported from Peru.
Sexing Males possess a urogenital papilla immediately behind the anus, and a variably deep skin fold along the first, unbranched pelvic-fin ray (vs. both absent in females). Also, males possess a much larger nostril than females, causing the internarial distance to be smaller in males. The larger size of the olfactory organ of males also causes an elevation in the snout profile immediately in front of the eyes, which can be easily seen in lateral view. In most species, males also possess longer pelvic fins than females, with the males' pelvic fins reaching or almost reach to the anal-fin origin.
