摘要: Biochemical genetics was applied to clarify the taxonomic status of colour morphs Quasitetrastemma nigrifrons and sibling species stimpsoni. Five two were compared using 17 24 allozyme loci, respectively. The high average genetic identity value obtained for most Q. (I = 0.981) suggests that they belong same species. Both stimpsoni have a lower I-value (I = 0.718 ± 0.089) are therefore considered be separate According data, var. pallidum is heterogeneous group; specimens more similar nigrifrons, although some closer
