Ng, HH, 2015. Phylogenetic systematics of the Asian catfish family Sisoridae (Actinopterygii: Siluriformes). Ichthyological Exploration of Freshwaters 26: 97–157.
Abstract
The results of a phylogenetic analysis of the Asian catfish family Sisoridae are presented in this study. The phylogenetic relationships of 106 (out of the 246) species of sisorid catfishes (representing over 40 % of the species diversity) were elucidated utilizing 197 morphological characters. Although a parsimony analysis failed to fully resolve the relationships of the 106 species in this study, nearly all of the genera analyzed (20 out of 22, with the exception of Ayarnangra and Erethistes) were recognized as natural; diagnoses for all 23 sisorid genera are provided. Novel generic interrelationships within the family were also recovered in this study. Two clades within the Sisoridae were recovered (Glyptosterninae and Sisorinae), with the Sisorinae being recovered as composed of three subclades (Bagariini, Erethistini and Sisorini). Diagnoses for these clades are provided, and aspects of the phylogeny in relation to the historical biogeography, as well as the evolution of body size and the thoracic adhesive apparatus in the group are also discussed.
