“…Lateral segmental respiratory body extensions seem to evolve easily in various leech groups. Recently, Sket et al . (2001) found prominent gill‐like extensions in a cave‐adapted erpobdellid, a structure utterly unexpected for any arhynchobdellid leech.…”

Phylogenetic relationships of fish leeches (Hirudinea, Piscicolidae) based on mitochondrial DNA sequences and morphological data. -Zoologica Scripta, 33 , 375 -385. Phylogenetic relationships of fish leeches (Piscicolidae) were deduced from combined mitochondrial DNA sequences of 12S rDNA and COI genes using Bayesian inference and Maximum Likelihood, as well as from a combined molecular-morphological data matrix using Maximum Parsimony. Monophyly of the family was confirmed. The traditional subdivision into three subfamilies, the Platybdellinae, Pontobdellinae, and Piscicolinae, received weak support, but was not challenged by alternative groupings. In contrast to prior classifications, a basal split emerged between the Pontobdellinae on the one hand, and the Platybdellinae and Piscicolinae on the other. The complex coelomic system of pontobdellines is viewed as plesiomorphic, and independent reductions of the coelom in other fish leech groups are hypothesized. According to the inferred phylogeny, seawater was the primary habitat of fish leeches. Eurasian freshwaters were colonized by a species-rich freshwater clade (genera Piscicola , Baicalobdella , Cystobranchus and Caspiobdella ) and, probably independently, by the Asian genus Limnotrachelobdella .

“…The speciation processes are exceptionally complex, conditioned by numerous biological (mutations, recombination, genetic drift, reproductive selection, allopatric fragmentation), climatic, geological and hydrological processes, which result in different aspects and mechanisms of reproductive isolation (e.g., Dobzhansky 1970;Nei 1975). All these processes result in diversity and emergence of a great number of endemic and relict taxa in certain areas like the Dinarids and the Balkan Peninsula (e.g., Casale & Jalžić 1999;Sket et al 2001;Casale et al 2004;Mihoci & Š ašić 2005;Mihoci et al 2007;Mustafić et al 2008;Lakota et al 2009;Polak & Jalžić 2009;Schmitt 2009), and a great diversity in various animal groups (e.g., Gottstein Matočec et al 2002;Novak 2004;Ozimec 2004;Bedek et al 2006;Varga & Schmitt, 2008) including Trichoptera (e.g., Kumanski 1985Kumanski , 1988Kumanski & Malicky 1999;Malicky 2005;Ž ivić et al 2006). Interpretation of phylogeny of certain animal groups requires an integral approach including morphology, ecology, biogeography and molecular genetic analysis, including analysis of the mitochondrial and nuclear genes (Pauls et al 2008;Morgan et al 2009), as well as related species crossbreeding experiments (Lorković 1962(Lorković , 1974Lorković et al 1992).…”

Larval description, genetic and ecological features of Drusus radovanovici radovanovici Marinković-Gospodnetić, 1971 (Trichoptera, Limnephilidae) with some phylogenetic and taxonomic data on the bosnicus group in the Balkan Peninsula

Species of the genus Drusus usually inhabit cold springs and spring areas of mountain streams. Isolation of populations and a patchy distribution are reasons for high diversity and endemism in this genus. Nine taxa from the bosnicus group (genus Drusus) live in the Balkan Peninsula (Croatia, Bosnia and Herzegovina, Montenegro, Macedonia). This study has two main objectives. First, morphological, ecological, and genetic features (mitochondrial COI and 16S genes) of the final larval instar of Drusus radovanovici radovanovici from Bosnia and Herzegovina are analysed. Association of larvae and adults of D. radovanovici radovanovici is carried out according to genetic data (mitochondrial DNA) of adults and larvae, and supported by their distribution in Bosnia and Herzegovina. Second, phylogeny, taxonomy and distribution of taxa of the bosnicus group in the Balkan Peninsula are discussed. The analysis includes morphological and genetic data for the known larvae of the genus Drusus distributed in the Balkans. As a consequence, both subspecies of Drusus radovanovici are ranked as species (D. radovanovici and D. septentrionis stat. n.), and the status of other taxa from the bosnicus group is discussed.

Abstract. Ancient Lake Ohrid on the Balkan Peninsula is considered to be the oldest ancient lake in Europe with a suggested Plio-/Pleistocene age. Its exact geological age, however, remains unknown. Therefore, molecular clock data of Lake Ohrid biota may serve as an independent constraint of available geological data, and may thus help to refine age estimates. Such evolutionary data may also help unravel potential biotic and abiotic factors that promote speciation events.Here, mitochondrial sequencing data of one of the largest groups of endemic taxa in the Ohrid watershed, the leech genus Dina, is used to test whether it represents an ancient lake species flock, to study the role of potential horizontal and vertical barriers in the watershed for evolutionary events, to estimate the onset of diversification in this group based on molecular clock analyses, and to compare this data with data from other endemic species for providing an approximate time frame for the origin of Lake Ohrid.Based on the criteria speciosity, monophyly and endemicity, it can be concluded that Dina spp. from the Ohrid watershed, indeed, represents an ancient lake species flock. Lineage sorting of its species, however, does not seem to be complete and/or hybridization may occur. Analyses of population structures of Dina spp. in the Ohrid watershed indicate a horizontal zonation of haplotypes from spring and lake populations, corroborating the role of lake-side springs, particularly the southern feeder springs, for evolutionary processes in endemic Ohrid taxa. Vertical differentiation of lake Correspondence to: T. Wilke (tom.wilke@allzool.bio.uni-giessen.de) taxa, however, appears to be limited, though differences between populations from the littoral and the profundal are apparent. Molecular clock analyses indicate that the most recent common ancestor of extant species of this flock is approximately 1.99 ± 0.83 million years (Ma) old, whereas the split of the Ohrid Dina flock from a potential sister taxon outside the lake is estimated at 8.30 ± 3.60 Ma. Comparisons with other groups of endemic Ohrid species indicated that in all cases, diversification within the watershed started ≤2 Ma ago. Thus, this estimate may provide information on a minimum age for the origin of Lake Ohrid. Maximum ages are less consistent and generally less reliable. But cautiously, a maximum age of 3 Ma is suggested. Interestingly, this time frame of approximately 2-3 Ma ago for the origin of Lake Ohrid, generated based on genetic data, well fits the time frame most often used in the literature by geologists.
