Morphological And Molecular Data

Synostemon trachyspermus (F.Muell.) I.Telford & Pruesapan (Phyllanthaceae, Phyllantheae) is shown, by morphological studies and phylogenetic analysis using nrITS DNA sequence data, to be a heterogeneous species assemblage of four species. Phyllanthus rhytidospermus F.Muell. ex Müll.Arg., with a new combination provided as Synostemon rhytidospermus (F.Muell. ex Müll.Arg.) I.Telford & Pruesapan, and Sauropus hubbardii Airy Shaw, with a new combination as Synostemon hubbardii (Airy Shaw) I.Telford & Pruesapan, are re-instated as species. Phyllanthus arnhemicus S.Moore is lectotypified and placed in synonomy under Synostemon lissocarpus (S.Moore) I.Telford & Pruesapan, which is the new combination provided for Phyllanthus lissocarpus S.Moore (syn. Sauropus lissocarpus (S.Moore) Airy Shaw). Synostemon umbrosus I.Telford & J.J.Bruhl, a rare endemic from the Kimberley, Western Australia, is named as new. The newly described S. hamersleyensis I.Telford & Naaykens, endemic to the Pilbara, Western Australia, and the north-eastern Queensland endemic Sauropus aphyllus J.T.Hunter & J.J.Bruhl are shown to be closely related; the new combination Synostemon aphyllus (J.T.Hunter & J.J.Bruhl) I.Telford & Pruesapan is provided for the latter. Sauropus sp. A of Flora of the Kimberley Region, previously included within S. trachyspermus sens.lat., shows a more distant relationship and is named as Synostemon judithae I.Telford & J.J.Bruhl. Notes on distribution, habitat, phenology, conservation status, photomicrographs of seeds and a key to identification of the species are provided.

Idiococcobius Hayat, syn. nov., is synonymised with Coccobius Ratzeburg, based on morphological and molecular data from a new species of Coccobius from Malaysian Borneo. The new species is sufficiently similar morphologically to the type species of Idiococcobius to place it unambiguously within that genus, but molecular data from the new species, and a reassessment of the morphology of Idiococcobius, indicate synonymy of the two genera. Idiococcobius encarsoides Hayat is therefore transferred to Coccobius; resulting in the new combination: Coccobius encarsoides (Hayat), comb. nov.Coccobius islandicus Geng & Polaszek, sp. nov, is described from morphology and DNA sequence data.

Relationship Of

Generic circumscriptions and phylogenetic relationships of the Cape genera Capnophyllum, Dasispermum, and Sonderina are explored through parsimony and Bayesian inference analyses of nrDNA ITS and cpDNA rps16 intron sequences, morphology, and combined molecular and morphological data. The relationship of these genera with the North African genera Krubera and Stoibrax is also assessed. Analyses of both molecular data sets place Capnophyllum, Dasispermum, Sonderina, and the only southern African species of Stoibrax (S. capense) within the newly recognized Lefebvrea clade of tribe Tordylieae. Capnophyllum is strongly supported as monophyletic and is distantly related to Krubera. The monotypic genus Dasispermum and Stoibrax capense are embedded within a paraphyletic Sonderina. This complex is distantly related to the North African species of Stoibrax in tribe Apieae, in which the type species, Stoibrax dichotomum, occurs. Consequently, Dasispermum is expanded to include both Sonderina and Stoibrax capense. New combinations are formalized for Dasispermum capense, D. hispidum, D. humile, and D. tenue. An undescribed species from the Tanqua Karoo in South Africa is also closely related to Capnophyllum and the Dasispermum–Sonderina complex. The genus Scaraboides is described herein to accommodate the new species, S. manningii. This monotypic genus shares the dorsally compressed fruit and involute marginal wings with Capnophyllum, but is easily distinguished by its erect branching habit, green leaves, scabrous umbels, and fruit with indistinct median and lateral ribs, additional solitary vittae in each marginal wing, and parallel, closely spaced commissural vittae. Despite the marked fruit similarities with Capnophyllum, analyses of DNA sequence data place Scaraboides closer to the Dasispermum–Sonderina complex, with which it shares the erect habit, green (nonglaucous) leaves, and scabrous umbels.

Molecular analysis of the newly reinstated genus Synostemon F.Muell. (Phyllanthaceae, Phyllantheae), using ITS sequence data from the now densely sampled genus, confirmed that the previously recognised ‘Queensland clade’ consists of Synostemon albiflorus (F.Muell. ex Müll.Arg.) Airy Shaw, S. sphenophyllus Airy Shaw, Sauropus podenzanae (S.Moore) Airy Shaw and the undescribed Synostemon spinescens, sp. nov. ined., the latter being validated here as S. spinosus I.Telford & J.J.Bruhl. Morphological synapomorphies for the clade are as follows: linear, apiculate anthers that are connivent but only basally connate, and thickened, clavate, recurved stigmas. A new combination is provided under Synostemon for Sauropus podenzanae as Synostemon podenzanae (S.Moore) I.Telford & Pruesapan and Sauropus convallarioides J.T.Hunter & J.J.Bruhl is formally placed in synonymy under Synostemon sphenophyllus. Descriptions, distributional data and notes on ecology and conservation status are provided for these species. Phyllanthus albiflorus F.Muell. ex Müll.Arg., the basionym of Synostemon albiflorus, is lectotypified.

The systematic position of three Apiaceae-Apioideae taxa, Pinacantha porandica, Ladyginia bucharica and Peucedanum mogoltavicum, from Middle Asia and Afghanistan, is clarified based on nrITS DNA sequence data. In the molecular phylogenetic tree, the monotypic Pinacantha is placed in unresolved position within the Ferulinae. Although there is no morphological information on essential characters, we propose a new position of Pinacantha porandica within the genus Ferula. As a result a new combination Ferula porandica is proposed, with a new section Pinacantha to accommodate it. The attribution of Peucedanum mogoltavicum to Ferula has been confirmed, its correct name being Ferula lithophila. The genus Ladyginia should not be included in Ferula, its closest relatives being Mozaffariania and Glaucosciadium from the Glaucosciadium Clade.

A New Species

Leptodeira is one of the most widespread and taxonomically problematic snake taxa in the Americas. Here we describe a new species of Leptodeira from the Andes of southern Ecuador based on morphological and molecular data. The new species is geographically close and morphologically similar to L. ornata and L. larcorum, from which it can be distinguished by having smaller dorsal body blotches, a longer tail, and shorter spines on the hemipenial body. The shortest genetic distances between the new species and its congeners are 0.02 (16S), 0.05 (cytb), and 0.18 (ND4). The new species is restricted to the Jubones River Basin in southern Ecuador, an area of endemism for other reptile species. Our phylogenetic analysis based on mitochondrial and nuclear DNA sequence data also supports recognition of the names L. larcorum (restricted to Peru) for “L. septentrionalis larcorum”, and L. ornata for populations of “L. s. ornata” from central and eastern Panama, western Colombia, and western Ecuador. However, some samples of “L. s. ornata” from Panama and Costa Rica, as well as the new species described herein, are not included within or more closely related to L. ornata, which is sister to the clade (L. bakeri, L. ashmeadii).

The systematics of the genus Hannia Vari 1978, endemic to freshwater habitats of remote north-western Australia, is revised in light of recent collections in the region and a molecular study of the group that identified an undescribed candidate species. A new freshwater fish species (Hannia wintoni sp. nov) is described based on analysis of multiple nuclear genetic markers (53 allozyme loci), mitochondrial DNA sequence data (601 bp cytochrome b) and morphology (examination of a suite of 66 morphometric and meristic characters). Head profile, postorbital length, maximum length, preopercular spines and pectoral-fin rays are characters that best distinguish H. wintoni sp. nov from its only congener, H. greewayi. While the existing description of H. greenwayi is robust and accurate, we present a number of additional characters that enhance to the original description, based on type and fresh material. Information on the known distribution, habitats and conservation status of the two species is summarised. The new species is a narrow-range endemic.

Morphological And Molecular Data

In this study, we explored the evolutionary history and taxonomic treatment of the Caragana opulens complex taking information from morphological and molecular data. The complex consists of three species, C. opulens, C. licentiana and C. kansuensis. Moreover, the morphological characters currently used to differentiate the species present in the complex have been found insignificant and inconsistent and do not help diagnose the species. For the present study, we investigated its range and sampled 139 accessions from the different populations of the genus Caragana and 17 accessions of the complex. DNA sequence data from one nrDNA ITS and one cpDNA trnH-psbA loci were sequenced and analyzed using Maximum Likelihood and Bayesian methods. The resulting phylogenies were congruent in topologies. Based on morphological and molecular data, it is concluded that all three species of the complex are one of the same with significant morphological variations. Hence C. opulens is accepted as the correct name along with C. licentiana and C. kansuensis as synonyms.

Menyanthaceae consist of five genera of aquatic and wetland plants distributed worldwide. The three monotypic genera (Liparophyllum, Menyanthes, and Nephrophyllidium) are clearly differentiated morphologically, but the two larger genera (Nymphoides and Villarsia) contain several taxa of uncertain affinity. We undertook a phylogenetic analysis, using a combination of morphological and molecular data, to resolve relationships among species and to evaluate the current circumscription of genera. DNA sequence data for nuclear (ITS) and chloroplast (rbcL and trnK/matK) gene regions were largely congruent (by partition-homogeneity test), and a combined data phylogeny revealed several strongly supported relationships. Analyses using asterid outgroup taxa supported the monophyly of Menyanthaceae. Menyanthes trifoliata and Nephrophyllidium crista-galli comprised a clade sister to the remainder of the family. Species of Nymphoides, except N. exigua, resolved to a single, deeply-nested clade, indicating that the floating-leaved habit is derived evolutionarily within the family. The genus Villarsia comprised a paraphyletic grade toward Nymphoides, wherein the species resolved to three assemblages: (1) a shallowly nested clade containing V. albiflora, V. calthifolia, V. marchantii, V. parnassifolia, V. reniformis, and V. umbricola; (2) an isolated South African clade including V. manningiana and the type species, V. capensis; and (3) a heterogeneous clade of taxa from three genera, including V. exaltata, V. lasiosperma, and V. latifolia, plus the anomalous species V. capitata, V. congestiflora, Liparophyllum gunnii, and Nymphoides exigua. Our results indicate that the genera Menyanthes, Nephrophyllidium, and Nymphoides should be retained as circumscribed, with the exception that Nymphoides exigua should be restored to Villarsia. The genus Villarsia, however, eventually should be subdivided among monophyletic lineages, whereby in the strict sense Villarsia would contain only South African taxa.

Stictidaceae comprises taxa with diverse lifestyles. Many species in this family are drought resistant and important for studying fungal adaptation and evolution. Stictidaceae comprises 32 genera, but many of them have been neglected for decades due to the lack of field collections and molecular data. In this study, we introduce a new species Fitzroyomyces hyaloseptisporus and a new combination Fitzroyomycespandanicola. We also provide additional morphological and molecular data for Ostropomyces pruinosellus and O. thailandicus based on new collections isolated from an unidentified woody dicotyledonous host in Chiang Rai, Thailand. Taxonomic conclusions are made with the aid of morphological evidence and phylogenetic analysis of combined LSU, ITS and mtSSU sequence data. Characteristics such as the shape and septation of ascospores and conidia as well as lifestyles among genera of Stictidaceae are discussed.

One New Species

The number of subterranean taxa discovered in the north of Western Australia has substantially increased due to the requirements for environmental surveys related to mining development. Challenges in estimating subterranean biodiversity and distributions are related to lack of knowledge of taxa with convergent morphological characters in a largely unobservable ecosystem setting. An integrated approach is warranted to understand such complexity. Bathynellidae occur in most Australian aquifers, but only one species has been described so far, and the group lacks a reliable taxonomic framework. A new genus and one new species from the Pilbara region of Western Australia, Pilbaranella ethelensis, gen. et sp. nov., is described using both morphological and molecular data. Three additional species of Pilbaranella are defined through mitochondrial and nuclear genes, using Automatic Barcode Gap Discovery and Poisson Tree Processes species delimitation methods. A comparison of morphology and 18S rRNA sequences between Pilbaranella, gen. nov. and known lineages provides the evidentiary basis for the decision to establish a new genus. This study provides a morphological and molecular framework to work with Bathynellidae, especially in Australia where a highly diverse fauna remains still undescribed.
