|Scientific Name||Microglanis ater Ahl, 1936|
|Common Name||South American Bumblebee Catfish|
|Type Locality||Brazil [as Mitttelbrazil].|
|Etymology||Micro - small, glanis - catfish - in reference to the rather small forms of catfish that this genus contains.|
|Size||81mm or 3.2" 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 Ahl (1936): Body height 3 2/3 times the body length, head length 3 1/2 times. Head slightly wider than long, flat; Rounded snout; Eye 3 2/3 times the length of the snout, 7 1/2 times the length of the head, 3 1/2 times the interorbital width; Maxillary barbel as long as the mental barbel, not reaching to the beginning of the pectoral spine; Postmental barbel even shorter; Mouth wide, the corner in front of the eye; both front jaws of equal length; anterior nostrils clearly tubular; Groups of premaxillary teeth without backward protruding angles. Dorsal I 6, its distance from the tip of the snout 2 3/5 times the length of the body; the spine a little over 1/2 the length of the head. Anal 14, rounded. Base of the dorsal, anal and adipose fin about the same length. Pectoral spine strong, with large serrations
|General Remarks||According to Bizerril & Perez-Neto (1992), M. ater is very similar in appearance to M. nigripinnis. Both species are easily distinguished from all other Microglanis species by their color pattern, with most of the body black, except for two paler bands, and with the pectoral, ventral, anal, adipose and dorsal fins almost completely black. M. ater differs from M. nigripinnis mainly in the number of anal fin rays (15 vs 12) and in having a shorter dorsal spine (2.4 in predorsal length, vs. 1.52 to 1.75).|
