Cryptic diversity in Dinarids: Phylogeography of Troglocaris anophthalmus (Crustacea: Decapoda: Atyidae) and Austropotamobius torrentium (Crustacea: Decapoda:Astacidae)
The abundance of cryptic species i.e. morphologically unrecognized species, even in well-known taxa or groups of taxa, is increasing with an extensive use of molecular techniques and growing number of phylogeographical studies. Our recent studies on two Decapod species from different families have revealed a concealed level of diversity and endemism in Dinaric fresh and groundwaters. One of them is the cave shrimp Troglocaris anophthalmus from the groundwaters and the other is freshwater crayfish Austropotamobius torrentium which were both considered uniform across a broad geographical area. We tested these species for possible cryptic diversity and/or unexpected evolutionary processes, analyzing mitochondrial 16S rRNA and COI genes. The results of a range of molecular phylogenetic and phylogeographic procedures congruently suggested that the Dinaric Karst is “ hot spot” for cryptic diversity and speciation. Both taxa seems to be composed of possibly five monophyletic, geographically defined phylogroups that meet several species delimitation criteria, two of them showing evidence of biological reproductive isolation in sympatry regarding the case of Troglocaris anophthalmus.
