“…The Sisoridae has been consistently recognized as a natural group based on morphological data (de Pinna, 1996;Diogo et al, 2002). In support of Guo et al (2004Guo et al ( , 2005, our results indicate that Chinese sisorid catfishes are a monophyletic group composed of two major lineages, one represented by (Gagata, (Bagarius, Glyptothorax)) and the other by Glyptosternini (i.e., Pseudecheneis and glyptosternoids).…”

Several recent molecular phylogenetic studies of the sisorid catfishes (Sisoridae) have challenged some aspects of their traditional taxonomy and cladistic hypotheses of their phylogeny. However, disagreement with respect to relationships within this family in these studies highlights the need for additional data and analyses. Here we subjected 15 taxa representing 12 sisorids genera to comprehensive phylogenetic analyses using the second intron of low-copy nuclear S7 ribosomal protein (rpS7) gene and the mitochondrial 16S rRNA gene segments both individually and in combination. The competing sisorid topologies were then tested by using the approximately unbiased (AU) test and the Shimodaira-Hasegawa (SH) test. Our results support previously suggested polyphyly of Pareuchiloglanis. The genus Pseudecheneis is likely to be nested in the glyptosternoids and Glaridoglanis might be basal to the tribe Glyptosternini. However, justified by AU and SH test, the sister-group relationship between Pseudecheneis and the monophyletic glyptosternoids cannot be rejected based on the second intron of rpS7 gene and combined data analyses. It follows that both gene segments are not suitable for resolving the phylogenetic relationships within the sisorid catfishes. Overall, the second intron of rpS7 gene yielded poor phylogenetic performance when compared to 16S rRNA gene, the evolutionary hypothesis of which virtually agreed with the combined data analyses tree. This phenomenon can be explained by the insufficient length and fast saturation of substitutions in the second intron of rpS7 gene, due to substitution patterns such as frequent indels (insertion/deletion events) of bases in the sequences during the evolution.

“…The Sisoridae has been consistently recognized as a natural group (de Pinna, 1996;Diogo et al, 2002) based on morphology. Despite the low support for this node in ML, MP, and NJ analysis, these results are congruent with morphology, which further lends support to the hypothesis of monophyletic sisorids.…”

A standardized terminology for the anatomy of pectoral- and dorsal-fin spines in the order Siluriformes is proposed based on an extensive literature review and direct examination of representatives of the order. The adult anatomy of the spines is described in detail. Terminology of various spine parts are reviewed and standardized, each term provided with a synonymic list organizing previous usage. Most of the structures treated have been recorded and named in the literature, but some are herein named for the first time. A quantitative approach is proposed for orienting decisions on name usage, aiming at minimizing differences between the terminology proposed and the vast amount of pre-existing literature, herein called the cost function. It is expected that this system will aid efforts in organizing the chaotic anatomical nomenclature of the appendicular skeleton in Siluriformes, and provide a solid basis for advances in comparative anatomy and nomenclature. The proposed terminology system has potential application on a number of fields that utilize information from catfish spines, ranging from taxonomy to phylogenetic systematics to paleontology and archaeology.
