Abstract Phylogenetic relationships among the antpitta genera were studied using DNA sequence data from the mitochondrial genome. The clade representing the traditional “antpitta” genera (Grallaria, Grallaricula, Hylopezus, Myrmothera, and Pittasoma) was found to be paraphyletic, owing to the sister relationship of Pittasoma and Conopophaga. In a previously unreported relationship, Pittasoma was strongly supported as the sister genus to Conopophaga (Conopophagidae). The remaining antpitta genera form a fully resolved and well-supported monophyletic lineage with two major subclades. The first clade consists of the genus Grallaria and supports the subgenera identified by Lowery and O'Neill (1969). The second antpitta clade has Hylopezus as the sister genus to Myrmothera, with Grallaricula as their sister genus. The results here allow for a new interpretation of the morphological characters used in previous studies.

Phylogenetic relationships among the families in the infraorder Sejina and the position of Sejina relative to other infraorders of Mesostigmata are re-examined based on molecular and morphological data. Data sets included DNA sequence data for complete 18S, EF-1 , partial CO1genes, and 69 morphological characters. The two families of Heterozerconina consistently group within Sejina, and we propose to synonymize Heterozerconina with Sejina (Sejina s.l). Microgyniina is not the closest relative of Sejina. Rather, Sejina s.l. most often groups with Gamasina. Uropodellidae and Ichthyostomatogasteridae are sister groups and this lineage forms the sister group to Discozerconidae plus Heterozerconidae. Overall, we recognize 5 families within Sejina: Uropodellidae, Ichthyostomatogasteridae, Sejidae, Discozerconidae, and Heterozerconidae.

The new combination Wurmbea novae-zelandiae was recently made based on published phylogenetic studies, but little information was provided on its relationships based on morphology. This species was originally described as Anguillaria novae-zelandiae, for which a lectotype is designated. Morphological characters of W. novae-zelandiae are re-evaluated and shown to be characteristic of Wurmbea, thereby supporting the revised generic placement. However, W. novae-zelandiae differs from all other Wurmbea species in its diminutive stature, fewer tepals and stamens, and variable floral morphology, with 1–3 carpels, often leaf-like tepals, and aberrant tepal shape and number. DNA sequence data places W. novae-zelandiae as the sister species of W. uniflora, a species not included in earlier phylogenetic studies. These two species share mostly solitary flowers with white tepals, nectaries two per tepal and similar in form and position, small yellow anthers, and styles that are relatively short and recurve as flowering proceeds, with the inner style surface stigmatic for up to half of its length. A revised generic description of Wurmbea is provided to take account of the recently widened concept.

AbstractThe molecular phylogeny of extant genets (Carnivora, Viverridae,Genetta) was generated using all species with the exception of the Ethiopian genetGenetta abyssinica. Herein, we provide the first molecular phylogenetic assessment ofG. abyssinicausing molecular sequence data from multiple mitochondrial genes generated from a recent record of this species from the Forêt du Day (the Day Forest) in Djibouti. This record represents the first verified museum specimen ofG. abyssinicacollected in over 60 years and the first specimen with a specific locality for the country of Djibouti. Multiple phylogenetic analyses revealed conflicting results as to the exact relationship ofG. abyssinicato otherGenettaspecies, providing statistical support for a sister relationship to all other extant genets for only a subset of mitochondrial analyses. Despite the inclusion of this species for the first time, phylogenetic relationships amongGenettaspecies remain unclear, with limited nodal support for many species. In addition to providing an alternative hypothesis of the phylogenetic relationships among extant genets, this recent record provides the first complete skeleton of this species to our knowledge and helps to shed light on the distribution and habitat use of this understudied African small carnivore.

Onobrychis, comprising more than 130 species, is a genus of the family Fabaceae. At this time, the interspecies relationship of this biologically important genus is still a subject of great discussion and debate. To help resolve this disagreement, we used molecular phylogeny to analyse internal transcribed spacer (ITS) and trnL–trnF sequences of 76 species of Onobrychis. Bayesian interference, maximum parsimony and maximum likelihood analyses of nuclear ITS and plastid trnL–trnF DNA sequence data generated trees with strong posterior probability for two groups: Onobrychis subgen. Sisyrosema (including: Heliobrychis, Hymenobrychis, Afghanicae and Anthyllium sections) along with Laxiflorae section in Group I and Onobrychis subgen. Onobrychis (except Laxiflorae section) in the other (Group II). The Laxiflorae section roots back to the ancestral node for Sisyrosema subgen. O. viciifolia (cultivated species), which is closely associated with O. cyri var. cyri, suggesting that the latter may be a wild progenitor of O. viciifolia. The present study supported the paraphyly of subgenera Onobrychis and Sisyrosema. The study proposed the paraphyletic nature of the sections Onobrychis, Dendrobrychis, Heliobrychis and Hymenobrychis. Together with our molecular phylogenetic analyses we present a review of Onobrychis morphology and discuss and compare our results with those of earlier morphological and molecular phylogenetic analyses.
