Comparative anatomy of the cheek muscles of Korean cobitid fishes (Ostariophysi: Cypriniformes), with the comments on their phylogenetic relationships

Cheek muscles of 16 species of all Korean cobitid species belong to six genera were examined and described in detail, with comments on their phylogenetic relationships made on the basis of characteristics of cheek muscles. Korean cobitids were divided into two groups, the Cobitis and Misgurnus groups, by five characters related to three cheek muscles (adductor mandibulae, preorbitalis, and retractor arcus palatine). The former group, comprising Cobitis, Iksookimia, Kichulchoia, Koreocobitis, and Niwaella, is defined by four apomorphies, and the latter, including Misgurnus, by a single apomorphy.     

Long-term stability of the seasonal succession of different zooplankton species in a brackish water lagoon (southern Baltic Sea)

While it has been widely suggested that freshwater fishes from East Asia invaded the western Palaearctic, details about this process are largely unknown. Here, using the cytochrome b gene, we evaluated the phylogenetic relationships of a small group of Eurasian primary freshwater fishes (Cobitidae), which are widely distributed and species rich in East Asia and Europe, with the purpose of inferring their invasion process of Europe from East Asia. Though phylogenetic relationships of cobitids were not well resolved, our analysis could identify three sister groups formed by the European and East Asian cobitids, which brought new insights into the biogeography of the genera Cobitis, Misgurnus, and Sabanejewia. The present results support the view that Asian cobitid fishes may have invaded Europe at least five times independently, and once reverse colonization of European cobitids to East Asia could also be found. Ancestral Sabanejewia might have been the first cobitids to cross Siberia and invade the EMZS (Euro-Mediterranean zoogeographic subregion) about 33.54 million years ago (MYA). One lineage of Cobitis and the ancestor of Misgurnus fossilis (Linnaeus) almost in the same time invaded the Europe, responding to 16.71 MYA and 16.59 MYA, respectively. Three different lineages of Cobitis were found to have invaded the EMZS from East Asia, and once reverse invasion to East Asia occurred to one subclade of European Cobitis. And our data also suggest that the diversity of East Asian cobitid fishes, especially of the genus Cobitis, is greatly underestimated. Handling editor: C. Sturmbauer     

Molecular phylogeny and intraspecific structure of loaches (genera <Emphasis Type="Italic">Cobitis</Emphasis> and <Emphasis Type="Italic">Misgurnus</Emphasis>) from the Far East region of Russia and some conclusions on their systematics

Russian Far East loaches of the genera Cobitis and Misgurnus are among members of the family Cobitidae with poorly understood systematics. In this study we present phylogenetic hypotheses based on mitochondrial (cytochrome b) and nuclear (RAG-1) sequences. All analyses recovered comparable topological phylogenies, and all data sets supported the non-monophyly of the genera Cobitis and Misgurnus. Both genera are represented by multiple lineages that in some cases do not correspond to the species described. We found some phylogenetic incongruities for the genus Misgurnus (M. mohoity and M. anguillicaudatus) that are explained by ancient hybridization, as was suggested previously for M. anguillicaudatus. The revealed phylogenetic relationships suggest that Paramisgurnus should be treated as a synonym of Misgurnus and M. bipartitus as a synonym of M. mohoity. All analyses recovered C. choii as a member of the genus Cobitis, confirming previous taxonomic conclusions. Most of the molecular lineages found follow currently recognized taxa with some exceptions, such as M. anguillicaudatus and C. lutheri. Phylogenetic relationships recover several unrelated lineages of M. anguillicaudatus and suggest additional studies to solve current taxonomic uncertainty. We found that C. lutheri is a non-natural group that contains two unrelated lineages: specimens of C. lutheri from the Far East of Russia collected close to the type locality and a second lineage with specimens of C. lutheri from Korea, the identification of which must be revised. The study provides evidence of the presence of the Far East species M. nikolskyi in Sakhalin Island, but simultaneously shows conspicuous genetic distinctiveness between the island and the mainland populations.     

Phylogeny and divergence times of some racerunner lizards (Lacertidae: Eremias) inferred from mitochondrial 16S rRNA gene segments

Eremias, or racerunners, is a widespread lacertid genus occurring in China, Mongolia, Korea, Central Asia, Southwest Asia and Southeast Europe. It has been through a series of taxonomic revisions, but the phylogenetic relationships among the species and subgenera remain unclear. In this study, a frequently studied region of the mitochondrial 16S rRNA was used to (i) reassess the phylogenetic relationships of some Eremias species, (ii) test if the viviparous species form a monophyletic group, and (iii) estimate divergence time among lineages using a Bayesian relaxed molecular-clock approach. The resulting phylogeny supports monophyly of Eremias sensu Szczerbak and a clade comprising Eremias, Acanthodactylus and Latastia. An earlier finding demonstrating monophyly of the subgenus Pareremias is corroborated, with Eremias argus being the sister taxon to Eremias brenchleyi. We present the first evidence that viviparous species form a monophyletic group. In addition, Eremias przewalskii is nested within Eremias multiocellata, suggesting that the latter is likely a paraphyletic species or a species complex. Eremias acutirostris and Eremias persica form a clade that is closely related to the subgenus Pareremias. However, the subgenera Aspidorhinus, Scapteira, and Rhabderemias seem not to be monophyletic, respectively. The Bayesian divergence-time estimation suggests that Eremias originated at about 9.9 million years ago (with the 95% confidence interval ranging from 7.6 to 12 Ma), and diversified from Late Miocene to Pleistocene. Specifically, the divergence time of the subgenus Pareremias was dated to about 6.3 million years ago (with the 95% confidence interval ranging from 5.3 to 8.5 Ma), which suggests that the diversification of this subgenus might be correlated with the evolution of an East Asian monsoon climate triggered by the rapid uplift of the Tibetan Plateau approximately 8 Ma.     

西北太平洋海岸带大弹涂鱼复合体的隐存种与进化历史

大弹涂鱼Boleophthalmus pectinirostris间断分布于西太平洋海岸带东亚与马来西亚马六甲海峡,但马来西亚种群的分类地位尚存争议。研究使用线粒体ND5基因序列（718 bp）与核位点Rag1基因序列（1395 bp）对西北太平洋海岸带11个地点的45尾大弹涂鱼属鱼类进行系统发育关系重建,结果表明大弹涂鱼包括东亚与马来西亚两个单系群,两者形成姊妹群关系。GMYC分析、*BEAST物种树支持大弹涂鱼东亚谱系和马来西亚谱系是不同种。分子测定年龄分析表明大弹涂鱼东亚谱系与马来西亚谱系之间的分化时间为2.73百万年。因此,西北太平洋海岸带大弹涂鱼是复合体,包括两个物种:东亚种群是大弹涂鱼Boleophthalmus pectinirostris sensu stricto,而马来西亚种群是隐存种Boleophthalmus sp.。大弹涂鱼与隐存种之间的物种分化可能是晚上新世冰期海平面下降产生的地理隔离以及间冰期洋流对基因交流的阻碍两方面相互作用的结果。       

Phylogeny and speciation time estimation of two Koreocobitis species (Teleostei; Cypriniformes; Cobitidae) endemic to Korea inferred from their complete mitogenomic sequences

The genus Koreocobitis (Teleostei; Cypriniformes; Cobitidae) is endemic to Korea and consists of two species. Koreocobitis naktongensis was recently separated from Koreocobitis rotundicaudata and erected as a novel species based on distinct morphological differences. Additionally, they show disjunctive separation in biogeography; K. rotundicaudata inhabits only the Han River drainage of the East Korea Subdistrict, and K. naktongensis is found only in the Nakdong River drainage of the South Korea Subdistrict. We determined the complete mitogenomic sequences of these two species to evaluate their phylogenetic position and to estimate the speciation time inferred from the partitioned nucleotide matrix of concatenated mitochondrial genes. The phylogenetic analysis revealed that the two Koreocobitis species consistently branched out together and formed a monophyly with Misgurnus species, with high statistical support within the cobitid lineage. The speciation time between the two Koreocobitis species was estimated to be 18.8 ± 3.7 million years ago (Mya), which is quite younger than that between two subdistrict populations of Coreoleuciscus splendidus showing the identical biogeographical separation pattern (ca. 31.2 Mya). These results indicate that the Noryeong/Sobaek Mountain Ranges functioned as an apparent vicariant barrier that not only allowed speciation of the Koreocobitis species but also contributed to the high genetic differentiation of C. splendidus populations for such a long period of time.     

Phylogenetic position of the genus Ferula (Apiaceae) and its placement in tribe Scandiceae as inferred from nrDNA ITS sequence variation

Recent molecular systematic investigations suggested that Ferula, an umbellifer genus of about 170 species, is polyphyletic, with its members placed in the apioid superclade and within tribe Scandiceae. We analyzed ITS sequence variation from 134 accessions of Apiaceae, including 83 accessions (74 species) of Ferula to ascertain the phylogenetic position of the genus within the family. Phylogenetic analyses of these data using maximum parsimony, Bayesian, and neighbor-joining methods support the monophyly of Ferula upon the addition of Dorema and Leutea (as Ferula sensu lato) and its placement in tribe Scandiceae. Ferula sensu is closely allied with other major lineages of Scandiceae, corresponding to subtribes Scandicinae, Daucinae, and Torilidinae. Therefore, we recognize the Ferula clade as subtribe Ferulinae. Another addition to tribe Scandiceae is a clade composed of genera Glaucosciadium and Mozaffariania. The three accessions of Ferula misplaced in the apioid superclade represent a species of Silaum.     

Cryptic variation in mole voles Ellobius (Arvicolinae,Rodentia) of Mongolia

The mole vole subgenus Ellobius is currently considered to include three species: Ellobius talpinus (distributed from SE Europe and Turkmenistan through Kazakhstan to SW Siberia), Ellobius alaicus (S Tianshan, Pamir-Alay) and Ellobius tancrei (East and West Central Asia, from the Amu-Darya to Mongolia and N China). A study focusing on the genetic variation in Ellobius from Mongolia was conducted using one mitochondrial and three nuclear markers. Two divergent allopatric lineages endemic to East Central Asia were revealed. The first lineage occurs from Dzungaria eastwards to central Mongolia and represents E. tancrei sensu stricto. The second lineage is found in East Gobi only and corresponds to a taxon described as Ellobius orientalis, which has been traditionally treated as a subspecies of E. tancrei. However, molecular and chromosome data indicate that orientalis is related not to E. tancrei but to E. talpinus, which is separated from the former by a distribution gap of ~2,000 km. The taxonomic status of the East Gobi mole vole is ambiguous, and its genetic distance from E. talpinus s. str. falls into the range characteristic for closely related vole species or semi-species. According to molecular estimates, the two taxa have been isolated since the late Middle Pleistocene. A similar divergence is observed between the East and West Central Asian lineages of E. tancrei. E. alaicus is placed as sister to the latter rendering E. tancrei sensu lato paraphyletic. The revealed phylogeographic pattern implies that East Central Asia was colonized by mole voles through multiple eastward dispersal events.     

Molecular systematics of sclerosomatid harvestmen (Opiliones, Phalangioidea, Sclerosomatidae): geography is better than taxonomy in predicting phylogeny

Phylogenetic relationships within the Sclerosomatidae, the largest family of harvestmen, are explored using molecular data from four nuclear genes (28S and 18S rRNA, Histone 3 and Elongation factor-1α) and two mitochondrial gene regions (COI-COII, 16S and 12S rRNA). The taxon sample includes representative species from all families in Phalangioidea and all subfamilies of Sclerosomatidae (Gagrellinae, Gyinae, Leiobuninae, Sclerosomatinae). Our results solve several major taxonomic problems, including placement of Gyinae sensu stricto in Phalangiidae, the monophyly of the Metopilio group and its exclusion from Sclerosomatidae, and reaffirmation of the familial rank of Protolophidae. However, most major groups of sclerosomatids (Leiobuninae, Gagrellinae, Leiobunum, Nelima) are recovered as polyphyletic, although with a phylogenetic structure suggesting a strong association between geography and monophyly as well as notable morphological convergence in traditional diagnostic characters. Phylogenetic affinities between biotas of the New World and Asian tropics, as well as between temperate North American and East Asia, suggest that sclerosmatid historical biogeography may conform with the Boreotropic Concept. Finally, we discuss how the many problems that remain in sclerosomatid systematics might be addressed.     

The genus Laetiporus (Basidiomycota, Polyporales) in East Asia

Relationships among East Asian, North American and European Laetiporus sulphureus s. lat., a cosmopolitan brown rot species complex, were assessed with phylogenetic analyses and incompatibility tests. Three East Asian taxa, Laetiporus cremeiporus sp. nov., Laetiporus montanus and Laetiporus versisporus, are described and illustrated as well as compared with related taxa from Southeast Asia, North America and Europe. Phylogenetic analyses showed that L. cremeiporus and L. versisporus are clearly distinct species among Laetiporus taxa. The three conifer inhabiting species, Laetiporus conifericola, Laetiporus huroniensis and L. montanus, are closely related to each other. The European population of L. montanus exhibits two sequence variants of the EF1α: one is the same as observed in L. sulphureus in Europe and the other is that observed in East Asian population of L. montanus. A key to the known species of Laetiporus in the northern hemisphere is provided.     

The Historical Speciation of Mauremys Sensu Lato: Ancestral Area Reconstruction and Interspecific Gene Flow Level Assessment Provide New Insights

Mauremys sensu lato was divided into Mauremys, Chinemys, Ocadia, and Annamemys based on earlier research on morphology. Phylogenetic research on this group has been controversial because of disagreements regarding taxonomy, and the historical speciation is still poorly understood. In this study, 32 individuals of eight species that are widely distributed in Eurasia were collected. The complete mitochondrial (mt) sequences of 14 individuals of eight species were sequenced. Phylogenetic relationships, interspecific divergence times, and ancestral area reconstructions were explored using mt genome data (10,854 bp). Subsequent interspecific gene flow level assessment was performed using five unlinked polymorphic microsatellite loci. The Bayesian and maximum likelihood analyses revealed a paraphyletic relationship among four old genera (Mauremys, Annamemys, Chinemys, and Ocadia) and suggested the four old genera should be merged into the genus (Mauremys). Ancestral area reconstruction and divergence time estimation suggested Southeast Asia may be the area of origin for the common ancestral species of this genus and genetic drift may have played a decisive role in species divergence due to the isolated event of a glacial age. However, M. japonica may have been speciated due to the creation of the island of Japan. The detection of extensive gene flow suggested no vicariance occurred between Asia and Southeast Asia. Inconsistent results between gene flow assessment and phylogenetic analysis revealed the hybrid origin of M. mutica (Southeast Asian). Here ancestral area reconstruction and interspecific gene flow level assessment were first used to explore species origins and evolution of Mauremys sensu lato, which provided new insights on this genus.     

The higher‐level phylogenetic relationships of the Eumeninae (Insecta,Hymenoptera, Vespidae), with emphasis on Eumenes sensu lato

Cladistic analyses were carried out to infer the phylogenetic relationships among taxa that were originally part of the large genus Eumenes. Terminals belonging to other eumenine lineages were also included, as well as terminals from other vespid subfamilies. Analyses under equal weights and implied weights were carried out, and better results were obtained with the latter. The results corroborated the monophyly of Eumeninae, and recovered Zethini sensu lato as the sister‐lineage to the remaining eumenines. Eumenes sensu lato as originally recognized is paraphyletic relative to Odynerus sensu lato. A natural classification at the tribal level congruent with the phylogenetic results may be proposed, and the names Zethini, Odynerini, and Eumenini are already available. This is the most comprehensive phylogeny of the Eumeninae to date. A new generic synonymy is Alfieria Giordani Soika, 1934 = Delta de Saussure, 1855.     

DNA sequence analyses reveal abundant diversity, endemism and evidence for Asian origin of the porcini mushrooms

The wild gourmet mushroom Boletus edulis and its close allies are of significant ecological and economic importance. They are found throughout the Northern Hemisphere, but despite their ubiquity there are still many unresolved issues with regard to the taxonomy, systematics and biogeography of this group of mushrooms. Most phylogenetic studies of Boletus so far have characterized samples from North America and Europe and little information is available on samples from other areas, including the ecologically and geographically diverse regions of China. Here we analyzed DNA sequence variation in three gene markers from samples of these mushrooms from across China and compared our findings with those from other representative regions. Our results revealed fifteen novel phylogenetic species (about one-third of the known species) and a newly identified lineage represented by Boletus sp. HKAS71346 from tropical Asia. The phylogenetic analyses support eastern Asia as the center of diversity for the porcini sensu stricto clade. Within this clade, B. edulis is the only known holarctic species. The majority of the other phylogenetic species are geographically restricted in their distributions. Furthermore, molecular dating and geological evidence suggest that this group of mushrooms originated during the Eocene in eastern Asia, followed by dispersal to and subsequent speciation in other parts of Asia, Europe, and the Americas from the middle Miocene through the early Pliocene. In contrast to the ancient dispersal of porcini in the strict sense in the Northern Hemisphere, the occurrence of B. reticulatus and B. edulis sensu lato in the Southern Hemisphere was probably due to recent human-mediated introductions.     

Ectomycorrhiza synthesis and basidiome formation of an orchid symbiont of the genus Thelephora on Quercus serrata

We induced basidioma formation of a fungus belonging to the Thelephoraceae that was isolated from the orchid Cephalanthera falcata. The mycobiont was isolated from root, cultured on modified Melin-Norkrans medium, and then inoculated onto fine roots of a Quercus serrata (Fagaceae) seedling. After observation of ectomycorrhiza formation, the Q. serrata seedling was grown in a pot. Thirty-six mo after ectomycorrhiza formation, basidioma formation was confirmed at the bottom of the pot. From comparisons in morphological characteristics between the mycobiont and known related Thelephoraceae species, and sequence similarities of internal transcribed spacer region in ribosomal DNA, we identified the mycobiont as Thelephora ellisii sensu lato in Thelephoraceae (Basidiomycota). Phylogenetic analysis indicated that the related sequences came from ectomycorrhizae of trees of the Salicaceae, Pinaceae, and Fagaceae distributed in East Asia, the USA, central Africa, and Europe.     

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.     

Phylogenetic relationships, character evolution, and biogeography of the subfamily Lygosominae (Reptilia: Scincidae) inferred from mitochondrial DNA sequences

Phylogenetic relationships among the lygosomine skinks were inferred from 1249 base positions of mitochondrial DNA sequences of 12S and 16S rRNA genes. The monophyly of this subfamily was confirmed and the presence of five distinct infrasubfamilial lineages detected. Of these, the Sphenomorphus group appears to have diverged first, followed by the Lygosoma and Egernia groups in order, leaving the Eugongylus and Mabuya groups as sister groups. Our results did not support monophyly of the Mabuya group sensu lato (i.e., an assemblage of the Lygosoma, Egernia, and Mabuya groups), for which a number of morphological and karyological studies demonstrated a considerable similarity. Our results also contradict the previous hypothesis, formulated on the basis of morphological and immunological data, which argued for the sister relationship between the Egernia and the Eugongylus groups. Morphological and karyological characters used to define the Mabuya group (sensu lato) may actually represent plesiomorphic states. The phylogenetic diversity of lygosomine skinks in the Australian region appears to have increased through multiple colonizations from Southeast Asia.     

Identification of a New Borrelia Species among Small Mammals in Areas of Northern Spain Where Lyme Disease Is Endemic

The role of small mammals as reservoir hosts for Borrelia burgdorferi was investigated in several areas where Lyme disease is endemic in northern Spain. A low rate of infestation by Ixodes ricinus nymphs was found in the small mammal populations studied that correlated with the near-absence of B. burgdorferi sensu lato in 184 animals tested and with the lack of transmission of B. burgdorferi sensu lato to I. ricinus larvae that fed on them. In contrast, questing ticks collected at the same time and in the same areas were found to carry a highly variable B. burgdorferi sensu lato repertoire (B. burgdorferi sensu stricto, Borrelia garinii, Borrelia valaisiana, and Borrelia afzelii). Interestingly, the only isolate obtained from small mammals (R57, isolated from a bank vole) grouped by phylogenetic analyses with other Borrelia species but in a separate clade from the Lyme disease and relapsing fever organisms, suggesting that it is a new species. This new agent was widely distributed among small mammals, with infection rates of 8.5 to 12% by PCR. Moreover, a high seroprevalence to B. burgdorferi sensu lato was found in the animal sera, suggesting cross-reactivity between B. burgdorferi sensu lato and R57. Although small mammals do not seem to play an important role as reservoirs for B. burgdorferi sensu lato in the study area, they seem to be implicated in the maintenance of spirochetes similar to R57.     

From Asia to Europe across Siberia: phylogeography of the Siberian spined loach (Teleostei,Cobitidae)

We assessed the genetic variability of the Siberian spined loach Cobitis melanoleuca across its unusually broad distribution that encompasses areas greatly affected by Pleistocene glaciations. Due to extensive morphological variation among their populations, the taxonomic status of C. melanoleuca is complicated. It is unclear whether C. melanoleuca represents a single taxonomic unit or contains several species or subspecies. Our analyses showed low genetic variability in all populations without any phylogenetic structure. The absence of molecular distinctiveness indicates the conspecificity of all C. melanoleuca populations. Only a few common haplotypes shared by East Asian, Siberian and European populations were found at high frequency in the nuclear genes analysed. At the mitochondrial level, Siberian populations shared haplotypes with populations located at both extremes of the species’ range suggesting central populations as a source of current mitochondrial variability. Unimodal mismatch distributions and significant values from neutrality tests support a recent expansion of C. melanoleuca. Our time estimates suggest a postglacial colonisation of European waters around 1.0 MYA, indicating that C. melanoleuca may represent the last cobitid immigrant in Europe that used the northern route across Siberia to expand its range.     

Intercontinental disjunctions in Cryptotaenia (Apiaceae, Oenantheae): an appraisal using molecular data

Aim The angiosperm genus Cryptotaenia (family Apiaceae, tribe Oenantheae) exhibits an anomalous distribution pattern, with five of its eight species being narrow endemics geographically isolated from their presumed relatives. We examined the monophyly of the genus and ascertained the phylogenetic placements of its constituent members in order to explain their distribution patterns. Location Eastern North America, eastern Asia, the Caucasus, southern Italy, Macaronesia and Africa. Methods In total, 173 accessions were examined for nuclear rDNA ITS sequence variation, representing nearly all major lineages of Apiaceae subfamily Apioideae and seven species of Cryptotaenia. Sampling of tribes Oenantheae, Scandiceae and Pimpinelleae was comprehensive. Phylogenetic analyses included Bayesian, maximum parsimony and neighbour‐joining methods; biogeographical scenarios were inferred using dispersal–vicariance analysis (diva ). Results Cryptotaenia is polyphyletic and includes three distant lineages. (1) Cryptotaenia sensu stricto (C. canadensis, C. japonica, C. flahaultii and C. thomasii) is maintained within tribe Oenantheae; C. canadensis and C. japonica, representing an eastern North American–eastern Asian disjunction pattern, are confirmed to be sister species. (2) Cryptotaenia elegans, endemic to the Canary Islands, is placed within Scandiceae subtribe Daucinae along with two woody endemics of Madeira, Monizia edulis and Melanoselinum decipiens. The phylogeny of these Canarian and Madeiran endemics is unresolved. Either they constitute a monophyletic sister group to a clade comprising some Mediterranean and African species of Daucus and their relatives, or they are paraphyletic to this clade. The herbaceous/woody genus Tornabenea from Cape Verde, once included in Melanoselinum, is not closely related to the other Macaronesian endemics but to Daucus carota. (3) The African members of Cryptotaenia (C. africana, C. calycina and possibly C. polygama) comprise a clade with some African and Madagascan umbellifers; this entire clade is sister group to Eurasian Pimpinella. Main conclusions Elucidating the phylogeny of the biogeographically anomalous Cryptotaenia sensu lato enabled hypotheses on the biogeography of its constituent lineages. Cryptotaenia sensu stricto exhibits a holarctic distribution pattern, with its members occurring in regions that were important glacial refugia. The genus probably originated in eastern Asia and from there dispersed to Europe and North America. For the Macaronesian endemic species –C. elegans, M. edulis and M. decipiens–diva reconstructs either a single dispersal event to Macaronesia from the Mediterranean/African region, or a single dispersal followed by a back‐dispersal to the mainland. The radiation of Tornabenea from Cape Verde followed a second dispersal of Daucinae to Macaronesia. Woodiness in Melanoselinum/Monizia and Tornabenea, therefore, is a derived and independently acquired trait. The African members of Cryptotaenia are derived from an ancestor arriving from the Middle East.
