“…With respect to timing, biogeographic–tectonic dating is being used in an increasing number of studies (Opgenoorth et al., 2021; Çıplak et al., 2022; Solà et al., 2022). We employed a more rigorous version of this method by dating multiple nodes, while treating fossil‐calibrated divergence dates as estimates of minimum, not maximum clade ages.…”

The butterfly subtribe Coenonymphina (Nymphalidae: Satyrinae) comprises four main clades found, respectively, in (1) the Solomon Islands, (2) Australasia, (3) NW South America and (4) Laurasia, with a phylogeny: 1 (2 (3 + 4)). In assessing biogeographic evolution in the group we rejected the conversion of fossil-calibrated clade ages to likely maximum clade ages by the imposition of arbitrary priors. Instead, we used biogeographic-tectonic calibration, with fossil-calibrated ages accepted as minima. Previous studies have used this approach to date single nodes (phylogenetic-biogeographic breaks) in a group, but we extended the methodology to date multiple nodes. Within the Coenonymphina as a whole, 14 nodes coincide spatially with ten major tectonic events. In addition, the phylogenetic sequence of these nodes conforms to the chronological sequence of the tectonic events, consistent with a vicariance origin of the clades. Dating of the spatially coincident tectonic features provides a timescale for the vicariance events. The tectonic events are: pre-drift intracontinental rifting between India and Australia (150 Ma); seafloor spreading at the margins of the growing Pacific plate, and between North and South America (140 Ma); magmatism flare-up along the SW Pacific Whitsunday Volcanic Province-Median Batholith (130 Ma); a change from extension in the Clarence basin, eastern Australia, to uplift of the Great Dividing Range (114 Ma); Pamir Mountains uplift, foreland basin dynamics and high eustatic sea-levels leading to marine transgression of the proto-Paratethys Ocean eastward to Central Asia and Xinjiang (100 Ma); predrift rifting and seafloor spreading west of New Caledonia (100-50 Ma); sinistral strike-slip displacement along the proto-Alpine fault, New Zealand (100-80 Ma); thrust faulting in the Longmen Shan and foreland basin dynamics around the Sichuan Basin (85 Ma); pre-drift rifting in the Coral Sea basin (85 Ma); and dextral displacement on the Alpine fault (20 Ma).

“…An alternative scenario of divergence as a result of the earlier documented insulation of Crete ca. 10 Ma (Dermitzakis, 1990; Dermitzakis & Papanikolaou, 1981) was ruled out, since it produces significantly old divergence times that contradict with independently estimated ages (Chobanov et al, 2017; Çıplak et al, 2022; Kaya et al, 2015). Divergence times were estimated from the concatenated dataset partitioned as follows—ND2 (positions 1–3), COI (positions 1–3), ITS1 + 2, 28 S, 16 S + 12 S (Table S2).…”

“…The Aegean Basin and its neighbouring areas have long attracted the scientists' attention for studying phylogeographic patterns in terrestrial animals (for a review see Poulakakis et al, 2015; also Avtzis et al, 2021; Borissov et al, 2020; Chobanov et al, 2017; Çıplak et al, 2022; Kaya & Çıplak, 2017; Kornilios et al, 2019; Trichas et al, 2020) as a result not only of the area's tempestuous geological history related to the Tethian tectonic belt (Robertson & Mountrakis, 2006) but also for its vast biological diversity.…”

“…The Aegean area is well‐known for its high biodiversity and endemism (Sfenthourakis et al, 2018). Among various groups with well outlined endemic species complexes (e.g., Allegrucci et al, 2017; Çıplak et al, 2022; Fattorini, 2002; Jesse et al, 2011) a typical example of diversification are the orthopterans, for which the Aegean in a broad sense (including the neighbouring mainland) is a centre of endemism for many genera, some tribes and even subfamilies (Çıplak, 2003, 2004; Çıplak et al, 2021; La Greca, 1999; Ünal, 2016). One of the most peculiar groups that define the faunal physiognomy of the northeastern Mediterranean is the hyperdiverse bush‐cricket tribus Barbitistini with over 300 known taxa (280 species) (Cigliano et al, 2021), of which ca.…”

Our study focuses on the origin, dispersal patterns, evolutionary strategies and systematics of Poecilimon, the largest bush‐cricket genus in the Palaearctic with over 150 taxa described. We employ phylogenetic and divergence time estimation analyses based on multilocus sequence data (ND2 + COI + 12 S + 16 S + ITS+28 S), perform ancestral area reconstruction, and track the evolution of behavioural (evolution of sound communication) and morpho‐physiological traits (body size and shape, and spermatophore size) in this genus. Based on our results, we propose a revised systematics of Poecilimon, including description of a new species, P. nivalis sp. n., and hypothesize three stages in the evolution of Poecilimon. (1) In the early evolution of the genus in Tortonian, when open dry habitats appeared in the Eastern Mediterranean, diversification rates were low and speciation was possibly induced by vicariance and habitat fragmentation; physiology and morphology during this period retained their ancestral states but the evolution of main lineages may have been accompanied by behavioural specializations. (2) Climate cooling and aridification during the Messinian induced dispersals and adaptation to new habitats, followed by physiological and behavioural adaptations; major clades formed or started diversifying. (3) Starting at the end of Messinian and continuing through the Plio‐ and Pleistocene, a few dispersal events from Anatolia to the Balkans took place and climatic oscillations were followed by allo‐ and parapatric divergence of habitat specialists, while ecological adaptations enhanced song diversity and led to morpho‐physiological changes.

“…The effective sample size parameters for each BEAST and MRBAYES analysis were monitored by TRACER v.1.7 (Rambaut et al, 2018), and trees were visualized using FIGTREE v.1.4.2. The BEAST analyses were calibrated using substitution rates estimated for Pholidopterini from the Tettigoniidae family (Orthoptera): specifically, 0.0187 substitutions per site per million year for COI and 0.018 for ND2 (Çıplak et al, 2022). This contrasts with the substitution rates of ITS in two subfamilies of Tettigoniidae, namely Phaneroprerinae and Tettigoniinae (Chobanov et al, 2017; Çıplak et al, 2015; Uluar & Çıplak, 2020), which also produced extremely different nodal ages when calibrating the ITS dataset (Çıplak et al, 2022).…”

The complex and dynamic history of the Anatolian Peninsula during the Pleistocene set the stage for species diversification. However, the evolutionary history of biodiversity in the region is shrouded by the challenges of studying species divergence in the recent, dynamic past. Here, we study the Poecilimon bosphoricus (PB) species group to understand how the bush crickets' diversification and the regions' complex history are coupled. Specifically, using sequences of two mitochondrial and two nuclear gene segments from over 500 individuals for a comprehensive set of taxa with extensive geographic sampling, we infer the phylogenetic and geographic setting of species divergence. In addition, we use the molecular data to examine hypothesized species boundaries that were defined morphologically. Our analyses of the timing of divergence confirm the recent origin of the PB complex, indicating its diversification coincided with the dynamic geology and climate of the Pleistocene. Moreover, the geography of divergence suggests a history of fragmentation followed by admixture of populations, suggestive of a ring species. However, the evolutionary history based on genetic divergence conflicts with morphologically defined species boundaries raising the prospects that incipient species divergences may be relatively ephemeral. As such, the morphological differences observed in the PB complex may not to be sufficient to have prevented homogenizing gene flow in the past. Alternatively, with the recent origin of the complex, the lack of time for lineage sorting may underlie the discord between morphological species boundaries and genetic differentiation. Under either hypothesis, geography—not taxonomy—is the best predictor of genetic divergence.
