Size 39mm or 1.5" SL. Find near, nearer or same sized spp.
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.

From original descriptionn (link in References): Microglanis pataxo can be identified by the color pattern with a dark blotch beneath adipose fin not extending to anal fin and by the high number of anal fin proximal radials, 12, shaped as rod-like thin tubes, the last one bearing a laminar extension. This species can be also recognized by the following combination of characters: a pectoral fin spine with a bony point and bearing proportionally few serrations on posterior border of pectoral fin spine, eight to ten. Seven pleural ribs and a proportionally short head width (67.8-74.3% in HL).
