The distribution of stone crayfish Austropotamobius torrentium (Schrank, 1803) (Crustacea: Decapoda: Astacidae) in the south-west Romanian mountain and sub-mountain area Data is presented in relation to the geographical distribution of the endangered crayfish species Austropotamobius torrentium. One hundred and seventy-four sampling stations situated along the streams of 15 geographical units from the South-West of Romania (Anina Mountains, Almăj, Dognecea, Godeanu, Locva, Ţarcu, Retezat, Semenic, Mehedinţi, Vâlcan, Parâng, Şureanu, Poiana Ruscă, Lipova Hills and Mehedinţi Plateau) have been investigated. A distribution map was compiled. The data from older publications were collated. The actual habitat of this species occupies a large area of South-West Romania in the mountain and sub-mountain area, being absent in the Poiana Ruscă Mts, Lipova and Dognecea Hills.

This paper presents the information about morphological variability and sexual dimorphism of the stone crayfish (Austropotamobius torrentium) in the area of Korana River in Mrkonjic Grad. The crayfish were caught by hand made baited traps from October 2018 to May 2019. A total of 46 crayfish were caught, of which 33 males and 13 females. The dimensions of eight morphometric characteristics: body weight (W), body length (TBL), rostrum length (ROL), rostrum width (ROW), claw length (CLL), carapace length (CPL), carapace width (CPW) and abdomen length (ABL), were analyzed, both in males and females. Also, the body condition was determined for all individuales. The measurements results of morphometric characteristics partially matched into the alredy known range of variations. These data presens first ones for the observed area. By using Mann-Whitey U-test, it was noted that there are significant differences between the sexes for W, TBL, CLL, CPL, CPW and ABL. These resuls could be explained by sexual dimorphism of the stone crayfish.
