We adopted a morphometric approach to provide statistical support for the description of two different morphotypes (I, reproductive, II, non-reproductive) firstly observed in Procambarus clarkii specimens caught population from Sardinia Island (western Mediterranean). The study was preceded by molecular taxonomic identification using mitochondrial Cytochrome C Oxidase subunit I (COI) gene. presence or absence pathogen Aphanomyces astaci, responsible plague, also investigated ribosomal Internal Transcribed Spacer (ITS) marker. estimation size at onset maturity (SOM) further performed males. Finally, structure examined. Our results confirmed entirety individuals as P. clarkii, and A. astaci. Morphological analysis revealed significant correlation between chela carapace lengths, while intra- inter-sexual dimorphism length occurrence morphotypes. SOM males established 35.0 37.1 mm length. size-population showed Gaussian distribution. recognition distinct crayfish could be useful an additional tool not only identify reproductive period this invasive crustacean but enrich guidelines correct species.
