Description: Dorsal spines (total): 1; Dorsal soft rays (total): 8; Vertebrae: 24 - 25. Differs from its congeners in having bifid serrations restricted to distal tip on ossified portion of pectoral spine posterior border (versus single or bifid serrations along entire posterior border) and presence of irregular arclike brown blotch on caudal peduncle (versus absence). Head with an irregular row of minute pores. The Aspidoras genera differ from Corydoras by their different behaviour such as their swimming habits. The eyes are smaller, body smaller and a smaller head shape in Aspidoras compared with Corydoras. Aspidoras posses a duel fontanel bone structure in the skull whereas Corydoras have only the one larger fontanel. Many species of Aspidoras are difficult to tell apart unless there is catchment information available. Lineage: All Aspidoras belong to Lineage 2 and when there is a revision they will stay as Aspidoras von Ihering, 1907 with the type species of A. rochai Ihering, 1907. As of the latest update (Dias et al 2024), Aspidoras depinnai has been placed in Lineage 2 and has retained the genus name of Aspidoras. Aquarium Care: Best kept in groups of six or more and are best housed with small fishes that are not aggressive. Provide a planted area in the tank for cover and include a soft substrate such as sand or small rounded gravel. Diet: Flake, tablet foods, small live and frozen foods. Etymology: The specific name depinnai: in honour of Brazilian ichthyologist Mário C. C. de Pinna, Universidade de São Paulo, who discovered this species, for numerous contributions to ichthyology, primarily in the study of catfishes. Remarks: Many species of Aspidoras are difficult to tell apart unless there is area catchment information available.
