Down Cat-eLog Data Sheet
Scientific Name Microglanis iheringi  Gomes, 1946
Common Name
Type Locality Río Turmero, Aragua, Venezuela.
Etymology Micro - small, glanis - catfish - in reference to the rather small forms of catfish that this genus contains. 
Down Species Information
Identification The genus Microglanis was described by Eigenmann (1912) to include small pimelodids with the head as wide as long, the skull covered by skin only; the occipital crest small; frontal fontanel not extending much if any behind the eye, and a minute occipital fontanel sometimes present; eye without a free orbital margin; dorsal and pectoral spines well developed; and premaxillary patches of teeth without backward projecting angles.

M. iheringi is identified by having a pale yellowish base color with a dark black or brown saddle beneath the dorsal fin and with a small pale spot inside the saddle. The lower lobe of the caudal fin is slightly larger (with more soft rays) than the upper lobe. Because so few examples exist of this species collected from its type locality, there is little more reliable information on this species.
Sexing Well-conditioned females are conspicuously wider in the abdomen than similarly sized males.
General Remarks Real Microglanis iheringi from the Turmero basin in Venezuela are essentially non-existent in the aquarium hobby. To our knowledge, all fish sold as M. iheringi in the hobby are M. aff. iheringi, collected along the Orinoco basin, mostly in Eastern Colombia, rather than from Northern Venezuela. The Orinoco fish represent at least three different species of Microglanis, all similar to M. iheringi in color pattern but each distinct in its own way. These species vary in size from 5cm to over 7cm maximum SL.
