|Cat-eLog Data Sheet|
|Scientific Name||Rhinotocinclus hardmani (Lehmann A., Lujan & Reis, 2022)|
|Type Locality||Kuribong River at Grass Shoals Rapids, Potaro-Siparuni, Guyana, 5°28'44.7"N, 59°31'54.4"W.|
|Synonym(s)||Parotocinclus hardmani, Rhinotocinclus hardmanii, Rhinotocinclus hardmanni|
|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.|
|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).|
|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.|
|General Remarks||Is misspelt R. hardmanni and R. hardmanii in Reis and Lehmann, 2022.|
