[Biomphalaria havanensis and Biomphalaria orbignyi (Pulmonata: Planorbidae). 2 species in synonymy?].
Morphometrics differences of 2 species of the genus Biomphalaria in Cuba (B. havanensis and B. orbignyi) were studied. These are potential intermediate hosts of schistosomiasis whose taxonomic location has been discussed. Of the variables measured the following coefficients were compared (length of the sheath of the penis/length of prepuce, caudal distance/cephalic distance, diameter of the shell/width of the shell) with the use of univariate and multivariate tests. Both tests proved that the length of the prepuce is the variable which discriminate best between both groups. These results complement other aspects which advocate for the taxonomic separation of these 2 species of planorbids [correction of plororbis].
