摘要
Specimens of Armadillidium aelleni Caruso & Ferrara 1982, from four Maltese caves were morphologically and genetically examined. Twelve enzymatic systems for a total of 15 loci (Pgm, Me, Got-1, Got-2, Idh-1, Idh-2, Mdh-1, Mdh-2, Phi, Ao, Est-1, Gapd, Pep-1, Acph, Fum) were analysed by horizontal starch gel electrophoresis. The populations studied were separated into two homogeneous groups by the presence of two diagnostic loci, Acph and Mdh-1, and a partially diagnostic one, Pgm; these results were confirmed by the morphological analysis. The two groups should be considered as a case of incipient speciation.
