Sažetak
The subterranean southern European genus Alpioniscus consists of two subgenera: Alpioniscus s.s. and Illyrionethes, with 33 species described. In Dinaric Karst, 13 nominal and 12 putative undescribed troglobiotic Illyrionethes have been recorded. The aim of the study was to confirm the existence of the nominal and undescribed species of the Dinaric Illyrionethes, bring insights into the phylogenetic groups, their mutual relationships, distributions and differential characters of the species. The molecular analyses using two mtDNA (16S rRNA and COI) and a nuclear gene (H3) fragments have been performed, as well as detailed taxonomical study on all nominal and seven undescribed Dinaric species. The results confirmed the validity of 12 out of 13 nominal and all undescribed species. The nominal species, A. bosniensis is considered to be a junior synonym of A. heroldi, based on molecular and morphological analyses. Seven new species have been described: A. iapodicus, A. hirci, A. velebiticus, A. lossinii, A. drazinai, A. mandalinae, and A. busljetai. As a result, 19 nominal species of Illyrionethes are currently known from the Dinaric Karst. They grouped into three distinct lineages: strasseri-, heroldi- and magnus-lineage. All lineages follow a northwest-southeast direction of the Dinaric Karst and have overlapping distributions. The strasseri-lineage was thoroughly sampled and highly supported by all phylogenetic methods employed, so a detailed morphological analysis was performed. Novel morphological characters, specific body part ratios (length and hump ending point of male pereopod 7 carpus ; length and concavity turning point male pleopod 1 exopod), are proposed for future species identifications.
