Abstract

Molecular, morphological and morphometrical studies were conducted on two species of the genus Monorchis (Monorchiidae), Monorchis parvus and Monorchis monorchis, collected in different fish hosts from the Mediterranean Sea. The analysis of internal transcribed spacer 1 sequences of ribosomal DNA showed that M. monorchis specimens from Parablennius gattorugine were strongly divergent (12.9%) from specimens of this species collected in Spondyliosoma cantharus and Diplodus puntazzo. This high genetic variation was confirmed by the analysis of morphological structures and morphometrics, which showed that M. monorchis specimens from P. gattorugine can be distinguished from those of S. cantharus and D. puntazzo by several morphological characteristics, including body size, number and distribution of vitelline follicles, testis shape, structure of the cirrus pouch
