Bryozoaires du Crétacé supérieur trouvés dans les résidusdu remplissage d'une fente karstique dans les Gorges du Nant (Vercors)

33 species of Upper Cretaceous silicified bryozoansfound by A. Arnaud-Vanneau and H. Arnaud (Grenoble) within a crevice filled with residual clay, have been studied. Most of the species are known from the Senonian (Coniacian — Santonian) of the Anglo-Paris Basin. The faunal relations with the Upper Cretaceous Bryozoa of the Provence, of the Aquitain Basin or the Alpine regions (Austrian Alps) are less significant. Decurella? arnaudae nov. sp. and Onychocella subpalpigera nov. sp. are described.     

Early Miocene cricetids (Rodentia) from the Junggar basin (Xinjiang, China) and their biochronological implications

Among the 14 small mammal species from the early Miocene locality of the northern area of the Junggar basin (northern Xinjiang, China), four species are cricetids (Rodentia): unnamed species of Cricetodon and Eumyarion, and two new species, Karydomys debruijni nov. sp. and Megacricetodon beijiangensis nov. sp. Some aspects of the morphology of Cricetodon sp. are shared by Eucricetodon from the late Oligocene, suggesting that these specimens could be of intermediate form between Eucricetodon and Cricetodon. One tooth of Eumyarion sp. was found, making its determination uncertain, but its morphology is clearly differentiated from the one of Cricetodon sp. The species K. debruijni nov. sp. is established based on its primitive features compared to the species known in Europe and Anatolia, and its specific association of characters compared to Karydomys dzerzhinskii. M. beijiangensis nov. sp. shows many plesiomorphic features compared to the species already described in the middle Miocene of China. Based on both the whole assemblage of rodents and the species of cricetids, the biochronologic position and the age of the locality are discussed. The locality appears to be biochronologically very close to the fauna from the Chul’adyr Formation in Aktau Mountains, but we propose an age slightly older than the one proposed for this fauna, probably equivalent to the MN3 biozone in Europe.     

The first representative Pliocene assemblages of passerine birds in Asia (Northern Mongolia and Russian Transbaikalia)

Passerine birds from two late Pliocene localities, Shaamar in northern Mongolia and Beregovaya in Transbaikalia (East Russia), represent the first known Neogene fossil assemblages of perching birds from Asia. A total of 11 families and 15 taxa are recognized, including a new genus and species of bunting, Pliocalcarius orkhonensis, apparently related to the Longspurs, and new species within the genera Hirundo and Rhodospiza, which are described. The avifauna is composed of open land and bush dwellers; it contains a few arid species, representing the oldest finds of the corresponding genera or lineages. This may indicate that the living Asian arid avian complex originated in Central Asia in the Neogene. Several genera (Rhodospiza, Paradoxornis) are documented in this paper for the first time in pre-Pleistocene deposits. Report of Calcarius is the first pre-Holocene evidence of the occurrence of this genus in Asia, which together with the remains of Synaptomys lemmings at Shaamar, illustrates faunal interchanges between North America and Asia in the Pliocene.     

New data on the Rectogordius (foraminifera) abundance zone (Latest Carboniferous: Gzhelian) of the Zaladou Formation (east-central Iran,Tabas block,Shishtu section)

The Rectogordius (Foraminifera) abundance zone is described in the east of the Shishtu village in the Ozbak Kuh Mountain. The samples were collected in the Zaladou Formation., which is 60 m thick and composed of shales, sandstones, sandy limestones, microconglomerate, bioclastic limestones, coral limestone and fusulinid limestones. The Rectogordius abundance zone was found in sandy bioclastic limestone. It displays two species and three subspecies of this foraminifer, including Rectogordius iranicus, R. iranicus gadukensis, R. minimus and R. minimus shishtuensis n. subsp., R. iranicus ozbakensis n. subsp. The age of this abundance zone is considered to be Gzhelian, due to the distribution of Rectogordius in Central Iran (Ozbak Kuh; Zaladou Formation), central and eastern Alborz (Emarat Fm.), Sanandaj-Sirjan zone (Vazhnan Formation), as well as in the Donets, Arctic Canada, Afghanistan, and the Carnic Alps. The genus Rectogordius is possibly restricted to the northern Paleotethys margin, northern Cimmerian margin, shelf of the Uralian Ocean as far as the northernmost part of North America. Two new subspecies Rectogordius minimus shishtuensis n. subsp. and Rectogordius iranicus ozbakensis n. subsp. are described.     

Tithonian-Berriasian foraminiferal faunas from the Torinosu-type calcareous blocks of the southern Kanto Mountains, Japan: their implications for post-accretionary tectonics of Jurassic to Cretaceous terranes

The Torinosu-type limestones, having many lithologic characters showing their original deposition on shallow shelves, are widely distributed in the Jurassic to Cretaceous terranes of Japan. The foraminiferal faunas from the Jurassic to the lowermost Cretaceous of Japan were first revealed in the calcareous blocks of the southern Kanto Mountains. Distinguished microfaunas consist of 39 species including many marker species of the Upper Jurassic to Lower Cretaceous in Europe, West Asia, and North Africa such as Melathrokerion spirialis, Charentia evoluta, Freixialina planispiralis, Nautiloculina oolithica, Everticyclammina cf. virguliana, Haplophragmium lutzei and Pseudocyclammina lituus. These faunas suggest a Tithonian to Berriasian age of Torinosu-type limestones. They are contained in four tectonostratigraphic units (Kamiyozawa, Hikawa and Gozenyama Formations; Ogouchi Group) continuously accreted from Middle Jurassic to Late Cretaceous. The younger deposition age of Torinosu-type limestones than the accretion age (Bajocian to Bathonian) in the Kamiyozawa Formation and their older age than the accretion age of the Ogouchi Group (late Albian to middle Maastrichtian) are important to date the post-accretionary tectonics of Jurassic to Cretaceous terranes of Japan and to explain the emplacement process of Torinosu-type limestones.     

Maastrichtian facies succession and sea-level history of the Hossein-Abad,Neyriz area,Zagros Basin

The Maastrichtian shallow-water carbonate platform (Tarbur Formation) is described from outcrop in southwest Iran. It is characterised by eight microfacies types, which are dominated by larger foraminifera, rudist debris and dasycladacean algae. They are grouped into four distinct depositional settings: tidal flat, lagoon, barrier and open marine. The depositional settings include stromatolitic boundstone of tidal flat, peloidal dasycladacean miliolids wackestone and peloid bioclastic imperforate foraminifera wackestone of restricted lagoon, Omphalocyclus miliolids bioclast packstone–grainstone and miliolids intraclast bioclast packstone–grainstone of open lagoon, rudist bioclast grainstone of inner-platform shoals and rudist bioclast floatstone–rudstone and bioclastic wackestone of open-marine environments.

The facies and faunal characters are typical of a ramp-like open shelf. The lack of reef-constructing organisms resulted in a gently dipping ramp morphology for the margin and slope. On the basis of facies analysis, three depositional sequences (third order) are defined.     

Pliensbachian gastropods from Venetian Southern Alps (Italy) and their palaeobiogeographical significance

Abstract: The Pliensbachian gastropods described by De Toni in 1912, coming from an isolated boulder at the foot of Mt Vedana (eastern margin of Trento Platform, Venetian Southern Alps, Italy) are revised. The fauna consists of 13 species representing nine families and eight superfamilies. Despite the low number of species, the assemblage represents the most diverse Early Jurassic gastropod fauna known for the Venetian Southern Alps. The boulder yielding the material was thought to derive from the upper part of the Early Jurassic Calcari Grigi Group, a carbonate platform unit extensively cropping out in the Mt Vedana area. The sedimentological analysis indicates a prevalently bioclastic wackstone‐floatstone, reflecting a lime‐muddy deposit undergone to an early consolidation. This and the high content of ammonoids, which is unusual for the Calcari Grigi Group, are typical aspects of a condensed pelagic sediment, presumably a fissure filling at the top of the carbonate platform succession. Palaeobiogeographical comparisons show that the fauna is composed of species occurring exclusively in pelagic limestones of the western Tethys. By contrast, it shows no relationships with the coeval faunas of the adjacent Trento platform and of the other western Tethyan carbonate platforms. These lines of evidence and the facies analysis would testify to the Pliensbachian drowning of the eastern margin of the Trento platform. In the wider context of the palaeobiogeographical history of Early Jurassic western Tethyan gastropods, the species from Vedana belong to a faunal stock which is typical for pelagic, mainly postdrowning sediments. Thus, appearance and diffusion in space and time of this stock were probably regulated by the direction, rate and pattern of the Neotethyan rifting. A new subgenus, Proarcirsa (Schafbergia) subgen. nov., and three new species, namely Ataphrus (Ataphrus) cordevolensis sp. nov., Guidonia pseudorotula sp. nov. and Proarcirsa (Schafbergia) zirettoensis sp. nov. are erected.     

Halorina cryptica nov. ichnogen., nov. ichnosp., mass-occurrence of Upper Triassic crustacean microcoprolites from neptunian dikes and sills cutting the Dachstein-type carbonate platform and their paleoenvironmental significance (Northern Apuseni Mountains,Romania)

The new crustacean microcoprolite Halorina cryptica nov. ichnogen., nov. ichnosp., is reported from cryptic cavities cutting the Upper Triassic (Carnian to lower Rhaetian) Dachstein-type limestones from the Northern Apuseni Mountains, Romania. The new ichnotaxon is extremely abundant in cavities, neptunian dikes and sills filled with red ferruginous carbonate sediment. The associated microfauna consists of ostracods and rare foraminifera. The microfacies is represented by bioclastic coprolite-bearing wackestone-packstone to grainstone. The red ferruginous carbonate fillings are strongly bioturbated. The neptunian sill located at the top of the studied section contains a rich ichnofauna associated with brachiopod accumulations. It is dominated by the dimerelloid rhynchonellid Halorella, indicating a late Norian-early Rhaetian age. Although neptunian dikes and sills are rather common in the Dachstein-type carbonate platform that extended on the northwestern Tethyan margin, we report here the first record of mass-occurrence of crustacean microcoprolites in neptunian dikes and sills filled with red carbonate sediments of marine origin. They are interpreted here as cryptic cavities with specific palaeoenvironmental features (e.g., lack of light, abundant nutrients, intensive microbial activity) where crustacean arthropods thrived.     

Paleocene and Lower Eocene shallow-water limestones of Tibet: Microfacies analysis and correlation of the eastern Neo-Tethyan Ocean

Microfacial investigations of the Lower Paleogene sediments were based on four sections of the passive Indian (Ladakh, Tingri County, Gamba County and Yadong County) and one of the active Asian continental margin (Zhongba County). Eleven microfacies from the Tethyan Himalaya (prefixed with P for passive continental margin) and four from the Xigaze forearc basin (prefixed with A for active continental margin) were observed. The distribution of fossil assemblages in the environment ranges from the tidal flat and restricted lagoonal part of the inner carbonate ramp to the outer carbonate ramp: (P1) green algae pack-/grainstone with small miliolids, (P2) bioclast grainstone, (P3) Rotaliidae packstone, (P4) Miscellaneidae-Rotaliidae-Nummulitidae pack-/grainstone, (P5) laminated and bioturbated mud- and grainstone, (P6) Alveolina wacke-/packstone with Soritidae, (P7) Nummulites-Alveolina-Orbitolites pack-/floatstone, (P8) Discocyclinidae-Nummulitidae pack-/floatstone, (P9) Rhodolith wacke-/packstone, (P10) mudstone with anhydrite nodules, (P11) planktonic foraminiferal wackestone, (A1) molluskan float-/rudstone, (A2) Nummulitidae wacke-/packstone, (A3) rhodolith wacke-/packstone, (A4) Discocyclinidae-Nummulitidae float-/rudstone. The correlation of our observations provides a detailed overview of the paleoenvironmental development and the sedimentary history of the eastern Neo-Tethyan Ocean, showing a deepening trend in two stages from Lower Paleocene to Lower Eocene.     

Revision of the late Visean-Serpukhovian (Mississippian) calcareous algae, foraminifers and microproblematica from Balia-Maden (NW Turkey)

The taxonomic revision of the carbonate microbiota of the limestone lenses intercalated into the Carboniferous siliciclastic series of Balia-Maden (Turkey) shows that most lenses are early or middle Brigantian in age (latest Visean), only a single lens being of younger age (late Serpukhovian). Calcareous microbiota are abundant in the Balia-Maden lenses carbonates. Microfacies analysis shows the dominance of shallow water environments. The Brigantian assemblage is accurately illustrated. The new foraminiferal taxon Cribrospira baliamadeni nov. sp. is morphologically similar to type-material of Cribrospira panderi von Möller, but has a porous wall with wider pores, almost keriothecal. C. baliamadeni nov. sp. corresponds to the misinterpreted Bradyina and Janischewskina of the previous literature on Balia-Maden lenses. These limestones show a great diversity of algosponges (carbonate microproblematica). Among them, (1) small, atypical Fasciella previously confused with Eosigmoilina; (2) an abundant form described for the first time, Frustulata reticulata nov. sp.; and (3) typical Falsocalcifolium punctatum (Maslov), important for the biostratigraphic implications, are also mentioned. The single Serpukhovian lens consists of a grainstone and contains the age-sensitive alga Archaeolithophyllum johnsoni Racz, and the foraminifers Monotaxinoides gracilis and Janischewskina sp.     

Lower Jurassic Bahamian-type facies in the Choč Nappe (Tatra Mts,West Carpathians,Poland) influenced by paleocirculation in the Western Tethys

The Lower Jurassic (upper Sinemurian) of the Hronicum domain (Tatra Mts., Western Carpathians, Poland) represents typical tropical shallow-water carbonates of the Bahamian-type. Eight microfacies recognized include oolitic-peloidal grainstone/packstone, peloidal-bioclastic grainstone, peloidal-lithoclastic-bioclastic-cortoidal grainstone/packstone, peloidal-bioclastic packstone/grainstone, peloidal-bioclastic wackestone, spiculitic wackestone, recrystallized peloidal-oolitic grainstone and subordinate dolosparites. The studied sediments were deposited on a shallow-water carbonate platform characterized by normal salinity, in high-energy oolite shoals, bars, back-margin, protected shallow lagoon and subordinately on restricted tidal flat. Some of them contain the microcoprolite Parafavreina, green alga Palaeodasycladus cf. mediterraneous (Pia) and Cayeuxia, typical of the Early Jurassic carbonate platforms of the Western Tethys. The spiculite wackestone from the upper part of the studied succession was deposited in a transitional to deeper-water setting. The studied upper Sinemurian carbonates of the Hronicum domain reveal microfacies similar to the other Bahamian-type platform carbonates of the Mediterranean region. Thereby, they record the northern range of the Lower Jurassic tropical shallow-water carbonates in the western part of the Tethys, albeit the thickness of the Bahamian-type carbonate successions generally decrease in a northerly direction. The sedimentation of the Bahamian-type deposits in the Hronicum domain, located during the Early Jurassic at about 28°N, besides other specific factors (i.e., light, salinity, and nutrients) was strongly controlled by the paleocirculation of warm ocean currents in the Western Tethys.     

Characterization of a new cosmopolitan genus of trypanosomatid parasites,Obscuromonas gen. nov. (Blastocrithidiinae subfam. nov.)

The expanding phylogenetic tree of trypanosomatid flagellates (Kinetoplastea: Trypanosomatidae) contains a long-known and phylogenetically well-supported species-rich lineage that was provisionally named as the ‘jaculum’ clade. Its members were found in representatives of several unrelated families of heteropteran bugs captured in South and Central America, Europe, Africa, and Asia. However, this group resisted introduction into the culture, a needed prerequisite for its proper characterization. Here we describe four new cultivable species, which parasitize various parts of their hosts’ intestine, including the thoracic and abdominal part of the midgut, hindgut, and Malpighian tubules. Morphologically, the cultured flagellates vary from relatively short stumpy promastigotes to long slender leptomonad cells. Some species form straphangers (cyst-like amastigotes) both in vivo and in vitro, initially attached to the basal part of the flagellum of the mother cell, from which they subsequently detach. To formally classify this enigmatic monophyletic cosmopolitan clade, we erected Obscuromonas gen. nov., including five species: O. modryi sp. nov. (isolated from the true bug host species Riptortus linearis captured in the Philippines), O. volfi sp. nov. (from Catorhintha selector, Curaçao), O. eliasi sp. nov. (from Graptostethus servus, Papua New Guinea), O. oborniki sp. nov. (from Aspilocoryphus unimaculatus, Madagascar), and O. jaculum comb. nov. (from Nepa cinerea, France). Obscuromonas along with the genus Blastocrithidia belongs to the newly established Blastocrithidiinae subfam. nov.     

Spatiotemporal Evolution of Calophaca (Fabaceae) Reveals Multiple Dispersals in Central Asian Mountains

Background

The Central Asian flora plays a significant role in Eurasia and the Northern Hemisphere. Calophaca, a member of this flora, includes eight currently recognized species, and is centered in Central Asia, with some taxa extending into adjacent areas. A phylogenetic analysis of the genus utilizing nuclear ribosomal ITS and plastid trnS-trnG and rbcL sequences was carried out in order to confirm its taxonomic status and reconstruct its evolutionary history.

Methodology/Principal Finding

We employed BEAST Bayesian inference for dating, and S-DIVA and BBM for ancestral area reconstruction, to study its spatiotemporal evolution. Our results show that Calophacais monophyletic and nested within Caragana. The divergence time of Calophaca is estimated at ca. 8.0 Ma, most likely driven by global cooling and aridification, influenced by rapid uplift of the Qinghai Tibet Plateau margins.

Conclusions/Significance

According to ancestral area reconstructions, the genus most likely originated in the Pamir Mountains, a global biodiversity hotspot and hypothesized Tertiary refugium of many Central Asian plant lineages. Dispersals from this location are inferred to the western Tianshan Mountains, then northward to the Tarbagatai Range, eastward to East Asia, and westward to the Caucasus, Russia, and Europe. The spatiotemporal evolution of Calophaca provides a case contributing to an understanding of the flora and biodiversity of the Central Asian mountains and adjacent regions.     

Biostratigraphie des brachiopodes et âge carixien (Pliensbachien inférieur) des calcaires à grands bivalves en Algérie occidentale

Recent researches on the Lower Jurassic of Western Algeria allow to establish a lithostratigraphic standard correlating the different members and formations developed in the Ouarsenis and Tlemcen Mountains, the Oran High Plains, the Nador and Ksour Mountains. The position of the large bivalve limestones (= Lithiotis limestones) is well established in the different lithologic successions. This facies is widespread in Western Algeria where it is interbedded with brachiopod marker beds, indicating short periods of maximum flooding. The large number of collected brachiopods are distributed into four “faunas” (assemblages) ranging from the Late Sinemurian (= Lotharingian) to the Early Pliensbachian (= Carixian). These faunas have been dated by the age of the species that they have in common with the NW european and western tethyan provinces. These chronological data are confirmed by rare ammonites. All these results evidence the age of the large bivalve facies in Western Algeria. They are contained in the Middle to Late Carixian (Demonense and Dilectum Zones). This datation is in conformity with that known from the Eastern High-Atlas (Bou Dahar). Consequently, the large bivalves cannot be considered as “markers for the unique Domerian” as it has been too often asserted. The palaeontological part of our study shows that the multicostate Zeilleriids (several Tauromenia species from the Late Sinemurian to the Early Carixian) are older than the multicostate Terebratulids (Hesperithyris species from the Middle to Late Carixian).     

New triconodontids (Mammalia) from the Lower Cretaceous Shahai and Fuxin formations, northeastern China

The first triconodontids from Asia have been discovered from the Lower Cretaceous (Aptian to Albian) Shahai and Fuxin formations in Liaoning Province, northeastern China: Meiconodon lii gen. and sp. nov. and M. setoguchii gen. and sp. nov. M. lii is characterized by molariform teeth with a developed cusp d, an m3 with taller cusp a, an m4 with three primary cusps of subequal height, the posteriorly decreasing transverse width of the m4, and a considerably reduced m5. M. setoguchii is slightly larger than M. lii, and characterized by a sharp labial cingulum on the m4, and a less developed cusp d on the molariform teeth than M. lii. The extensive interlocking system between molariforms, posteriorly recumbent primary molariform cusps, and their great degree of asymmetry in occlusal view with rounded labial faces and more angulate lingual faces in lateral view, indicate that Meiconodon belongs to the triconodontid subfamily Alticonodontinae. These new taxa are the first record of Triconodontidae from Asia, and of Alticonodontinae outside North America, suggesting the occurrence of mammalian faunal exchange between North America and Asia during or before the Aptian-Albian.     

Cicadas (Hemiptera: Cicadidae) from Panay,Philippines, with a new species and a new genus

This paper provides the first faunal checklist for Cicadidae (Hemiptera) from Panay, Philippines, comprising five species belonging to five genera. A new species, Platypleura lourensi sp. nov., and a new genus, Ggomapsalta gen. nov., are described. Dundubia vaginata (Fabricius, 1787) and Ggomapsalta vernalis (Distant, 1916) are newly recorded from Panay. Information on geographic distributions is provided.     

New latest Permian foraminifers from Laren (Guangxi Province, South China): Palaeobiogeographic implications

Microfacies analyses performed on the latest Permian Wujiaping Formation at Laren (Guangxi Province, South China) show that the bioclastic-rich limestones of Late Permian age contain a rich and well-diversified foraminiferal fauna. This fauna is here revised in order to be compared with time-equivalent levels of southern Iran and southern Turkey. Some new and unexpected phylogenetic trends are highlighted among the biseriamminoids. The new or poorly known genera Retroseptellina, Septoglobivalvulina, Paraglobivalvulinoides, Dagmarita?, Bidagmarita nov. gen., Louisettita, Paradagmaritopsis nov. gen. and Paradagmarita? are concerned. Nevertheless, these newly appeared biseriamminoids are subordinate to abundant Tetrataxis and Climacammina, ultimate survivors of the families Palaeotextulariidae and Tetrataxidae, appeared as old as the Early Carboniferous (“Mississippian”). Algae, miliolids, and nodosarioids are poorly represented. Two genera and four species are here newly described: Globivalvulina curiosa nov. sp., Louisettita ultima nov. sp., Bidagmarita nov. gen., Bidagmarita sinica nov. gen. nov. sp., Paradagmaritopsis nov. gen., Paradagmaritopsis kobayashii nov. gen. nov. sp. The palaeogeographic distribution of these foraminifers is interpreted to be typically of Neo-Tethyan regions, ranging from southern Turkey (Hazro) to South China (Laren) and up to Japan for some species (i.e., Paradagmaritopsis). At Laren, Late Permian strata are generally characterized by Reichelina ex gr. simplex Sheng. Isolated samples of packstones, collected in Tsoteng region (Guangxi Province, South China), contain Sphaerulina sp. together with various smaller foraminifers and numerous representatives of the new species G. curiosa nov. sp. In this study we demonstrate that the regions of Zagros (Iran), Taurus (Turkey), South China and even Japan shared similar foraminiferal assemblages and represented intermittently connected palaeobiogeographic provinces during Late Permian times.     

Des serpents (Reptilia,Squamata) de type nord-américain dans le Miocène Français. Évolution parallèle ou dispersion?

The French Miocene (Orleanian and Astaracian) yielded five new species of snakes referable to four genera from the Neogene or Recent of North America: Texasophis meini nov. sp., Paleoheterodon arcuatus nov. sp., Neonatrix europaea nov. sp., Neonatrix crassa nov. sp. (Colibridae) and Micrurus gallicus nov. sp. («Elapidae). It is suggested that Micrurus and the previously described boid snake Albaneryx from the French Miocene probably represent lineages that originated in North America and reached Europe by way of Asia. Paleoheterodon and Neonatrix could have originated in Asia and subsequently reached Europe on one hand and North America on the other. Texasophis may have originated in North America and followed the same route as Micrurus and Albaneryx, but an alternative hypothesis is that it originated in Asia and spread toward Europe and North America in the same manner as Paleoheterodon and Neonatrix.     

Molecular phylogeny and historical biogeography of the Anatolian lizard Apathya (Squamata,Lacertidae)

Apathya is a lacertid genus occurring mainly in south-east Turkey and its adjacent regions (part of Iran and Iraq). So far two morphological species have been attributed to the genus; A. cappadocica (with five subspecies, A. c. cappadocica, A. c. muhtari, A. c. schmidtlerorum, A. c. urmiana and A. c. wolteri) and A. yassujica. The first species occupies most of the genus’ distribution range, while A. yassujica is endemic of the Zagros Mountains. Here, we explored Apathya’s taxonomy and investigated the evolutionary history of the species by employing phylogenetic and phylogeographic approaches and using both mitochondrial (mtDNA) and nuclear markers. The phylogenetic relationships and the genetic distances retrieved, revealed that Apathya is a highly variable genus, which parallels its high morphological variation. Such levels of morphological and genetic differentiation often exceed those between species of other Lacertini genera that are already treated as full species, suggesting the necessity for a taxonomic revision of Apathya. The phylogeographical scenario emerging from the genetic data suggests that the present distribution of the genus was determined by a combination of dispersal and vicariance events between Anatolia and Southwest Asia dating back to the Miocene and continuing up to the Pleistocene. Key geological events for the understanding of the phylogeography of the genus are the movement of the Arabian plate that led to the configuration of Middle East (orogenesis of the mountain ranges of Turkey and Iran) and the formation of Anatolian Diagonal.
