|Scientific Name||Microglanis berbixae Tobes, Falconí-López, Valdiviezo-Rivera & Provenzano, 2020|
|Type Locality||Quebrada Sune, a tributary of Pachijal River, Esmeraldas River basin, Pacific slope, Parroquia de Pacto, Pichincha Province, Ecuador, 0°05'28.56"N, 78°53'53.04"W, elevation 960 meters.|
|Etymology||Micro - small, glanis - catfish - in reference to the rather small forms of catfish that this genus contains. The specific name “berbixae”, honor María Resurección Sesma Lizari, “Berbixe”, mother of Ibon Tobes Sesma, for its unconditional support and infinite love. A genitive.|
|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.
Microglanis berbixae is distinguished from congeners by its color pattern. Head and body uniform, pale brown, yellowish or grayish, without any kind of blotches, bands, or dots, except a transverse lunate band, dark brown or black, at caudal-fin origin (vs. head and body mottled or marbled brown with whitish or cream blotches, bands, or dots in other species). M. berbixae is further distinguished from M. variegatus, its geographically closest species, by belly pigmentation; in M. berbixae the belly color is uniform, yellowish or grayish brown, without aggregates of small black dots/melanophores (vs. usually possessing a whitish or creamy belly with randomly arranged aggregates of melanophores).
|Sexing||Females and males can be sexed by their genital papillae: Female: Cylindrical-shaped papilla with truncated ending and a small pointed flap. Male: Elongate and triangular papilla, pointed tip, no flap.|
|Distribution||Found in two small rivers of the Pachijal River system, the Sune and Mashpi Rivers, part of the Esmeraldas River Basin, Pacific Ocean versant, northwestern Ecuador, Pichincha province.
