Morphology of the gas bladder in bumblebee catfishes (Siluriformes, Pseudopimelodidae)

Abstract: The gross morphology of the gas bladder is described and compared for representatives of all valid genera of Pseudopimelodidae (Siluriformes). Cephalosilurus albomarginatus and species of Batrochoglanis, and Microglanis have the most basic form: a large, cordiform gas bladder with a simple internal T-shaped septum. Cephalosilurus apurensis, C. fowleri, and C. nigricauda also have a large, cordiform gas bladder, but they have well-developed trabeculae associated with the internal T-shaped septum, and a pair of … Show more

“…In sum, much of the evidence supporting a sister relationship of the Pseudopimelodidae and Heptapteridae is equivocal and this question requires further study. Indeed, swim bladder morphology (Birindelli, Shibatta, 2011) and molecular (Sullivan et al, 2013) evidence indicates a sister relationship of the Pseudopimelodidae with the Pimelodidae rather than the Heptapteridae.…”

“…The brain anatomy of the Callichthyidae and its relation to the phylogeny of the group was discussed by Pupo (2011), and recently, Rosa et al (2014) detailed the gross morphology of the brain of Neotropical catfi hes. The systematics and anatomy of the Pseudopimelodidae have been the subject of several studies (e.g., Lundberg et al, 1991;Shibatta, 1998Shibatta, , 2003Birindelli & Shibatta, 2011), but descriptions of the gross morphology of the brain in the group (and of the Siluriformes as a whole) remain scarce.
