Ongoing Speciation and Gene Flow between Taxonomically Challenging Trochulus Species Complex (Gastropoda: Hygromiidae)

Geographical isolation, selection and genetic drift can cause the geographical diversification of populations and lead to speciation. Land snail species in the genus Trochulus show overlaps in geographical ranges as well as in morphology, but genetic data do not always support the species-level taxonomy based on morphological characters. Such a group offers an excellent opportunity to explore the processes involved. We have addressed the problem by determining the status of the restricted endemic T. graminicola within the larger context of Trochulus taxonomy. We used an integrated approach based on morphological features, ecological preferences and two molecular markers: mitochondrial COI sequences and microsatellites. Comparison of these results demonstrated: (i) conchological distinction of T. striolatus and T. sericeus; (ii) anatomical, ecological and genetic differentiation of T. graminicola and (iii) concordance between morphological characters and mtDNA markers in T. striolatus. Moreover, our data showed an intricate evolutionary history within the genus Trochulus, which can be best explained by: (i) recent or ongoing gene flow between taxa or (ii) their large ancestral polymorphism. Both of these hypotheses suggest that diversification within this group of snails has occurred relatively recently. The mismatches between species defined on morphology and on molecular genetics indicate the complexity of the processes involved in the diversification of this genus.

“…The longest continuous record of glaciation in the Southern Alps comes from a core drilled from the sea floor about 300 km off the east coast of the South Island. This site, known as Deep Sea Drilling Programme (DSDP) site 594, consists of alternating layers of pelagic sediment derived from free-swimming marine organisms and hemipelagic deposits that consist in part FIGURES 3A AND B (a) Pleistocene glaciation of the Alps, based on Glückert (1987) and Lister et al (1998) of sediments derived from the Southern Alps (Nelson et al 1985). Analysis of the top 100 m of the core has yielded an apparently uninterrupted record of sedimentation that records 12 major periods of alpine glaciation over the last 730,000 years.…”

“…Moreover, N. enslini was only found in sites that were not covered by glaciers during the Last Glacial Maximum (Glückert 1987) but are located very close to the border of Quaternary glaciers. A similar distribution was already observed for the N. virei species complex (Foulquier et al 2008) with its main distribution area located west of the Alps and nearly never overlapping with formerly glaciated areas.…”

Niphargus enslini Karaman, 1932 was collected only once in 1905 from the Falkensteiner Höhle (Baden-Württemberg, Germany). Two years after its description, the species was synonymized with Niphargus virei and not studied any more. During recent surveys on German niphargids, further samples collected in this cave did not yield N. enslini specimens, but this species was collected in the Blätterteighöhle and in the Schwarzer Brunnen, two caves located in Baden-Württemberg and intercepting the same karstic aquifer feeding Falkensteiner Höhle. In an integrative taxonomic approach, we carefully studied the morphology of the newly collected specimens and sequenced two molecular markers (fragments of the cytochrome c oxidase subunit I (COI) and of the nuclear 28S rRNA gene) to test for possible conspecificity of N. enslini with N. virei. Morphological analysis confirmed that N. enslini is distinct from the N. virei species complex. We provide a redescription of newly collected material, together with new drawings of a more than 100 years old topotypic female. We briefly discuss the putative origin of N. enslini and the age of its split from the N. virei species complex.
