The taxonomy of Linderniaceae has been considered difficult, particularly in the establishment of a stable generic framework. The prevailing approach in Australia and globally has been to adopt a broad concept of Lindernia encompassing several segregates that have at various times been recognised as genera or subgeneric taxa. A recent global conspectus drawing on molecular phylogeny returned Lindernia to a narrower circumscription and also retained several long-recognised and more recently established genera. It included a polyphyletic Vandellia, encompassing many Australian species previously accepted as belonging in Lindernia. Here, we test these generic concepts using the phylogenetic analysis of plastid matK DNA sequences, including representatives of Australian Linderniaceae. We propose a generic taxonomy that resolves existing polyphyly and balances the need for name changes against the information conveyed by generic names. Our concept of Lindernia recognises three monophyletic subgenera. Evidence is insufficient to determine whether Micranthemum should be subsumed in Lindernia or remains a close ally with a sister relationship to it. In light of our findings, we return most of the Australian species to Lindernia; we also establish for the first time: Lindernia subg. Ilysanthes (Raf.) Wannan, W.R.Barker & Y.S.Liang, based on Ilysanthes Raf.; a replacement name Yamazakia W.R.Barker, Y.S.Liang & Wannan for Tittmannia Rchb. nom. rej., with consequential combinations Y. viscosa (Hornem.) W.R.Barker, Y.S.Liang & Wannan, based on Gratiola viscosa Hornem. and Y. pusilla W.R.Barker, Y.S.Liang & Wannan, based on Gratiola pusilla Willd.; and, in expanding Torenia, the combination Tor. anagallis (Burm.f.) Wannan, W.R.Barker & Y.S.Liang, based on Ruellia anagallis Burm.f.

Among New World direct-developing frogs belonging to the clade Brachycephaloidea (= Terraranae), there are several genera with uncertain phylogenetic placements. One notable example is the genus Niceforonia Goin & Cochran 1963, which includes three species that are endemic to Colombia. Three specimens of the species Niceforonia nana were collected and for the first time the genus is included in a molecular phylogenetic analysis of mitochondrial (mtDNA; 12S and 16S) and nuclear (nucDNA; TYR and RAG1) markers. Molecular phylogenetic inference based on concatenated and separate mtDNA and nucDNA analyses recovered Niceforonia nana nested within Hypodactylus Hedges et al. 2008, rendering the latter genus paraphyletic. Consequently, herein we place the genus Hypodactylus in the synonymy of Niceforonia to resolve the paraphyly and place Niceforonia in the subfamily Hypodactylinae. Based on our revised concept of the genus Niceforonia we conducted preliminary morphological comparisons using specimens and literature descriptions. Finally, Nicefornia nana is quite divergent from other species of Niceforonia (uncorrected genetic distances of ca. 10% 16S and 7% TYR) suggesting that further taxonomic revision may be warranted.

The derived liverwort Leiolejeunea grandiflora was recollected at the type locality in Jamaica after more than 100 years. The characteristics of its oil bodies were described for the first time based on the new collections. Each leaf cell possesses 2-4(-6) rather small, subhomogeneous to very finely segmented, subglobose to ellipsoidal, colorless oil bodies. The plants were either dioicous or autoicous. DNA sequences of two chloroplast regions (trnL-trnF, rbcL) and the nuclear ribosomal ITS region were obtained for two accessions of Leiolejeunea to enable the inference of the phylogenetic relationships of these plants. Based on Bayesian inference of phylogeny as well as maximum parsimony and maximum likelihood analyses of a dataset including 87 representatives of Lejeuneaceae, Leiolejeunea was found as the putative sister to either Echinolejeuneinae or Cheilolejeuneinae. Thus, we propose the new monogeneric subtribe Leiolejeuneinae with relationships to Cheilolejeuneinae and Echinolejeuneinae. The analyses included also one accession of the generitype of Cheilolejeunea, C. decidua [= Cheilolejeunea adnata]. This species was found in a well supported sister relationship with Cystolejeunea. To avoid nomenclatural confusion, we propose a wide genus concept for Cheilolejeunea including Aureolejeunea, Cyrtolejeunea, Cystolejeunea, Evansiolejeunea, Leucolejeunea, and Omphalanthus.

Pseudodactylaria fusiformis sp. nov. was collected during an investigation of freshwater fungi along a north-south latitudinal gradient in the Asian region. Evidence for the new species is provided by morphological comparison and sequence data analysis. Pseudodactylaria fusiformis differs from other species in having hyaline conidiophores and fusiform, 0–1-septate hyaline conidia without a sheath. Phylogenetic analysis based on combined ITS and LSU sequence data was carried out to determine the phylogenetic placement of the species. Six Pseudodactylaria taxa clustered together and formed a monotypic clade representing the genus, and five species are well recognized. Pseudodactylaria fusiformis and P. camporesiana share a sister relationship and they are phylogenetically distinct species. A detailed description and illustration are provided, as well as the comparisons with similar taxa.

A revision of the land snail genus Landouria Godwin-Austin, 1918 (Camaenidae) from Java reveals that this group represents the most diverse land snail radiation on that island. Only six species of Landouria were recognized from Java in the last revision of the genus based on shell characters. Our investigation, which also considers the genitalia as well as DNA sequences, shows that the diversity in Java is much higher. Based on newly collected specimens as well as museum material, twenty-eight species of Landouria from Java are described and figured. To stabilize the nomenclature, neotypes are designated for L. winteriana (Pfeiffer, 1842) and L. rotatoria (Pfeiffer, 1842). Sixteen species are described as new to science, i.e., L. naggsi sp. nov., L. parahyangensis sp. nov., L. nusakambangensis sp. nov., L. petrukensis sp. nov., L. tholiformis sp. nov., L. madurensis sp. nov., L. abdidalem sp. nov., L. sewuensis sp. nov., L. tonywhitteni sp. nov., L. sukoliloensis sp. nov., L. nodifera sp. nov., L. pacitanensis sp. nov., L. zonifera sp. nov., L. pakidulan sp. nov., L. dharmai sp. nov. and L. menorehensis sp. nov. Landouria conoidea (Leschke, 1914) comb. nov., L. intumescens (Martens, 1867) comb. nov., L. moussoniana (Martens, 1867) comb. nov., L. schepmani (Möllendorff, 1897) comb. nov. and L. leucochila (Gude, 1905) comb. nov. are considered valid species of the genus Landouria for the first time. Plectotropis kraepelini Leschke, 1914 syn. nov. is considered a probable synonym of L. winteriana (Pfeiffer, 1842), P. trichotrochium Möllendorff, 1897 syn. nov. is a synonym of L. epiplatia (Möllendorff, 1897) and the preoccupied name Helix squamulosa Martens, 1867 syn. nov. is a synonym of L. madurensis sp. nov. We estimate that there are actually more than fifty species of Landouria in Java because many shell samples could not be classified and because no material is available from several regions of the island. A molecular phylogeny reveals that the species from Java do not form a monophyletic group, but that at least one species from Timor is nested within Javanese clades. This means that the Oriental Landouria crossed Wallace’s line, the supposed border between the Oriental and Australo-Papuan regions, at least twice and supports the conclusion that Wallace’s line does not represent a more severe barrier for terrestrial organisms than other straits through the archipelago. Within the Javanese clades, species from western and eastern Java are mixed, indicating frequent dispersals also within Java.

A New Species

© 2020, © 2020 International Phycological Society. A new species of Polycoelia, P. kurariirapa, is described from the Three Kings Islands/Manawatāwhi, representing the first record of the genus in New Zealand. Polycoelia includes two species from Australia, P. laciniata (generitype) and P. fastigiata, and one from South Africa, P. harveyana. Polycoelia kurariirapa shares with the two Australian species the characteristic vegetative anatomy of the genus consisting of a single layer of medullary cells surrounded by a cortex of small-celled, anticlinal filaments, and branched thalli. The rbcL phylogenetic analysis confirmed the close, and sister, relationship of P. kurariirapa with the Australian taxa, while they were only weakly grouped with P. harveyana. This new genus adds to the unique seaweed flora of these islands in northern New Zealand and indicates that this area may harbour even more hidden diversity.

The phylogeny of Amauroderma and related genera were studied using DNA sequences from the internal transcribed spacer (ITS) and 28S nuclear ribosomal RNA gene regions. Amauroderma concentricum sp. nov. is described. The species is characterized by the yellowish brown to reddish brown pileal surface with concentric zones, a white pore surface unchanged when bruised, single to multiple stipes, small pores (4–5 per mm), and subglobose to globose and double-walled basidiospores, 8–9.2 × 7.2–8 µm. The phylogenetic analysis presented here confirmed that Amauroderma as traditionally accepted is not monophyletic.

A New Species

The first molecular phylogeny of Lynceus (Crustacea: Branchiopoda: Laevicaudata) is presented together with a description of a new species of laevicaudatan branchiopod from Chile, Lynceus huentelauquensis, sp. nov. DNA sequences were obtained from six species of Lynceus using freshly collected specimens from Europe, North America, South America, and Australia and combined with GenBank sequences from previous studies. Specimens of the new species were collected from a pool on the Huentelauquén Plains near Huentelauquén City. Our molecular analyses placed L. huentelauquensis, sp. nov. within Lynceus and close to a cluster of Australian species, and revealed morphological misidentifications, cross-contamination, or incorrect upload in earlier GenBank sequences. L. huentelauquensis, sp. nov. is separated from other Lynceus primarily by the morphology of the rostrum and the male claspers. L. huentelauquensis, sp. nov. is the first described laevicaudatan from Chile, the sixth from South America, and the 13th from the Americas. The morphology of laevicaudatans from the Americas is reviewed and an updated key to the (male) Lynceidae of the region is provided. Our study highlights the necessity of a revision of Laevicaudata using multiple genetic markers as well as thorough morphological studies on a greater number of taxa. urn:lsid:zoobank.org:pub:9A783D96-B270-40DF-8361-11BA063C9A0F

In order to provide a basis for better understanding of phylogenetic relationships of Saudi Arabian Tetraena Maxim. and Zygophyllum L., 44 specimens representing seven taxa, were reconstructed based on chloroplast DNA data of rbcL and trnL-F. The combined chloroplast (rbcL and trnL-F) contributed more phylogenetically informative characters than in individual regions. Phylogenetic analysis of the combined chloroplast (rbcL and trnL-F) and in individual regions based on both of Maximum Parsimony and Bayesian criteria showed that the Saudi Arabian species of Tetraena and Zygophyllum were monophyletic. Zygophyllum fabag L. was nested in one clade with Z. xanthoxylum (Bunge) Engl. (Asian species), and all taxa of Tetraena were distributed in other clades.Bangladesh J. Plant Taxon. 24(2): 155–164.

Heron hepatitis B viruses (HHBVs) in three subspecies of free-living great blue herons (Ardea herodias) from Florida, USA, were identified and characterized. Eight of 13 samples were positive in all assays used, whereas sera from egrets, which are also members of the family Ardeidae, were negative in the same assays. Comparative phylogenetic analysis of viral DNA sequences from the preS/S region of previously reported and novel HHBV strains isolated from captive grey herons (Germany) and free-ranging great blue herons (USA), respectively, revealed a strong conservation (95 % sequence similarity) with two separate clusters, implying a common ancestor of all strains. Our data demonstrate for the first time that different subspecies of herons are infected by HHBV and that these infections exist in non-captive birds. Phylogenetic analysis and the fact that the different heron species are geographically isolated populations suggest that lateral transmission, virus adaptation and environmental factors all play a role in HHBV spreading and evolution.
