No Picture Available

 Family:  Auchenipteridae (Driftwood catfishes), subfamily: Centromochlinae
 Max. size:  9.55 cm SL (male/unsexed)
 Environment:  benthopelagic
 Distribution:  South America: coastal rivers systems (Rio Doce and Rio Mucuri) in Brazil.
 Diagnosis:  Dorsal spines (total): 2-2; Dorsal soft rays (total): 5-5; Anal soft rays: 11-11; Vertebrae: 36-37. This species is diagnosed from other species of Glanidium, except G. albescens, by the presence of small dark spots over a pale yellow ground color (vs. large dark blotches over a pale brown ground color). It differs from G. albescens by having pectoral fin spine length, about 21-26 % in SL (vs. 17-20% in SL), 10 ribs (vs. 9) and 36-37 vertebrae (vs. 38-39). The possession of 36 or 37 vertebrae separates this species from G. cesarpintoi, G. albescens, G. leopardum, G. melanopterum, G. catharinensis, and G. ribeiroi (with 38 or 39 in G. cesarpintoi, 38 or 39 in G. albescens, 40 or 41 in G. leopardum, 41 in G. melanopterum, 41 in G. catharinensis, and 44 in G. ribeiroi). It also differs from other species by having anterior margin of the pectoral-fin spine with serrae on its entire margin (vs. serrae restricted to distal portion of spine in G. melanopterum, G. catharinensis and G. ribeiroi or smooth anterior margin in G. leopardum) and by a long sharpened ventral process on urohyal (vs distinctly short robust process in G. melanopterum, G. cesarpintoi, G. catharinensis, and G. ribeiroi) (Ref. 93811).
 Biology:  Occurs in lotic sections of rivers and also lakes. Active at night. Feeds on allochthonous resources, such as beetles, and autochthonous aquatic invertebrates, such as insect larvae and gastropods based on gut contents of 8.2 cm SL specimen (Ref. 93811).
 IUCN Red List Status: Not Evaluated  (Ref. 96402)
 Threat to humans:  harmless
