  abstract = {{W}ith the aim of detecting phylogenetic relationships among #{P}angasiidae$ catfishes, 23 enzyme loci were studied on 18 nominal species of the genera #{P}angasius$ and #{H}elicophagus$ ({R}oberts and {V}idthayanon, 1991). {I}n order to assess the taxonomic position of #{L}aides$ genus in the #{S}chilbeidae$ or in the #{P}angasiidae$, 2 species belonging to the genus #{L}aides$ and 1 species of the genus #{P}seudeutropius$ (#{S}iluriformes$, #{S}chilbeidae$) were added in the study. {T}he results indicate that the species #{L}aides hexanema$ and #{L}aides sinensis$ appear to be genetically related with the #{P}angasiidae$. {T}he phylogenetic tree obtained shows a clustering of species which validate the genus #{H}elicophagus$ but indicates that the genus #{P}angasius$ is polyphyletic. {T}he genus #{P}angasius$ is composed of 3 genetic differentiated groups. {G}roup 1 is composed of 3 species belonging to two different morphological entities validated by {R}oberts and {V}idthayanon (1991) as possible subgenus. #{P}angasius hypophthalmus$ and #{P}. gigas$ which share common genetic characters validate the subenus #{P}angasianodon$. {T}he possession of many private alleles by #{P}. pleurotaenia$ confirms the morphological originality of this species which was therefore considered to belong to the monotypic subgenus #{P}teropangasius$. {T}he second groupd consists of #{P}. micronema$, #{P}. macronema$, #{P}. lithostoma$ and #{P}. polyuranodon$ and the last group represents all the other species of the genus #{P}angasius$. {B}y contrast #{N}eopangasius$ considered as a possible subgenus by {R}oberts and {B}idthayanon (1991) is polyphyletic. {A}lthough relative genetic similarities were found between #{P}. humeralis$ and #{P}. nieuwenhuisii$ which are located in group 3, the species #{P}. lithostoma$ appears to be more closely related to species belonging to the group 2...
