“…In contrast, some genera, for example Lomatium Raf. and Cymopterus Raf., were morphologically well supported, and are located in the same clade according to molecular phylogenies (Downie et al , Carlson et al ). In this study, the morphological dataset does not support a monophyletic Tordylium because the putative outgroup Ormosciadium aucheri (Fig.…”

Tordylium is a medium‐sized genus characterized by an annual habit, 1–3‐pinnate leaves, dorsally compressed mericarps, and thickened mericarp margins. Eighteen Tordylium species occur in Turkey, of which seven are endemic. Although the morphology of the genus is well known, evolutionary relationships among its species have never been evaluated. In this study, phylogenetic relationships within Tordylium are investigated using parsimony analysis based on morphological data from 17 ingroup and 15 outgroup taxa from Turkey. The results indicate that Tordylium is paraphyletic due to the inclusion of Ormosciadium. Further, it suggests that Hasselquistia, Condylocarpus and Ainsworthia are nested within Tordylium, confirming their current taxonomic treatment as synonyms. Within the paraphyletic Tordylium, two major clades are apparent, but these clades are not compatible with the current sub‐generic classification. Tordylium lanatum, T. aegyptiacum and T. elegans, which have dimorphic mericarps, form a monophyletic subclade. In addition, it is suggested that T. aegaeum should be accepted as a distinct species rather than as a synonym of T. pestalozzae.

“…Molecular phylogenetic analyses have had major impacts on taxonomy and systematics at all ranks, including the resolution of species boundaries (Stepansky et al, ; Bronikowski & Arnold, ; Clark et al, ; Abbasi et al, ; Adl et al, ; Soltis et al, ; Hibbett et al, ; Carlson et al, ; Dauphin et al, ; Tomasello et al, ; Sukumaran & Knowles, ). In particular, molecular phylogenetic approaches have been important in identifying reciprocally monophyletic groups that can often be diagnosed on the basis of phenotypic character states (Froufe et al, ; Richards & Knowles, ; Winker, ; Guayasamin et al, ; Zimmers et al, ), ecological niches (Bond & Stockman, ; Gazis et al, ), or geographic distributions (Milá et al, ; Schuchert, ; Gaither et al, ; Friis et al, ).…”

Species boundaries have traditionally been delimited by applying phenotypic characters to a morphological species concept. With an increased understanding of the complexities of speciation as a process, species concepts have proliferated while at the same time, the ability to gather greater numbers and types of molecular characters has expanded the means by which species can be delimited. Phylogenetic studies of molecular data provide an opportunity to identify reciprocally monophyletic groupsand have led to the identification of cryptic or nearly cryptic species in which subtle differences in phenotypes or ecological niches can be uncovered only after monophyletic groups have been identified. Here, we investigate evolutionary relationships among a group of species in the Lomatium triternatum complex using molecular phylogenetic analyses for all samples, and ecological parameters for two of the 38 species included in this study. The results indicate that there are more reciprocally monophyletic groups in this complex than had been estimated using phenotypic data alone. The ecological data show a clear differentiation for the one pair of sister species where ecological sampling was available, implying that divergence within this group may have resulted from environmental selection for soil preferences that have been strong enough to result in speciation.

“…Ongoing collections of animal and plant groups in recent years has led to the identification of many new species (e.g., frogs: Anstis et al 2010;Doughty 2011;lizards: Doughty et al 2012;Oliver et al 2012Oliver et al , 2014Pepper et al 2011;snails: Köhler 2010snails: Köhler , 2011 flowering plants: Barrett et al 2009;Carlson et al 2011;Maslin et al 2013).

Australian death adders (genus Acanthophis) are highly venomous snakes with conservative morphology and sit-and-wait predatory habits, with only moderate taxonomic diversity that nevertheless remains incompletely understood. Analyses of mitochondrial and nuclear gene sequences and morphological characteristics of death adders in northern Australia reveal the existence of a new species from the Kimberley region of Western Australia and the Northern Territory, which we describe as Acanthophis cryptamydros sp. nov. Although populations from the Kimberley were previously considered conspecific with Northern Territory death adders of the A. rugosus complex, our mtDNA analysis indicates that its closest relatives are desert death adders, A. pyrrhus. We found that A. cryptamydros sp. nov. is distinct in both mtDNA and nDNA analysis, and possesses multiple morphological characteristics that allow it to be distinguished from all other Acanthophis species. This study further supports the Kimberley region as an area with high endemic biodiversity.
