ABSTRACT: Biochemical genetic approach was applied to clarify the taxonomic status of the hermit crab Pagurus gracilipes which was compared with five species of the family Paguridae (P. brachiomastus, P. ochotensis, P. middendorffii, P. proximus, P. minutus) and with two species of the family Diogenidae (Diogenes nitidimanus and Stratiotes nigroapiculus) using 18 allozyme loci. Genetic identity values between P. gracilipes and species of the family Paguridae (from 0.611±0.117 for P. gracilipes vs P. proximus, to 0.249±0.102 for P. gracilipes vs P. middendorffii) suggest that this species should retain its position in the genus Pagurus. This conclusion is supported by similar average identity value between other species of the genus Pagurus (I=0.444±0.110) and low genetic similarity between the genera Diogenes and Stratiotes (I=0.167±0.084) and between the families Paguridae and Diogenidae (I=0.102±0.005).
