Cultural Features

The aim of the present study was to characterise species of Antrodia s.l. from Patagonia, Argentina, and to determine their phylogenetic relationships by using morphological and cultural features as well as mating systems and ITS sequences. Phylogenetic trees generated from maximum-parsimony, neighbour-joining and Bayesian-inference analyses showed that the Argentinean collections were distributed inside the following three main clades: (1) ‘Antrodia clade’, with Antrodia ramentacea (Berk. & Broome) Donk as a sole representative; (2) ‘Amyloporia clade’, including Amyloporia nothofaginea Rajchenb. & Gorjón sp. nov. and A. stratosa (J.E.Wright & J.R.Deschamps) Rajchenb., Gorjón & Pildain comb. nov.; and (3) ‘Fibroporia clade’, with Fibroporia vaillantii (DC.) Parmasto and F. gossypium (Speg.) Parmasto. ‘Amyloporia’ and ‘Antrodia clades’ did not have strong molecular support; however, they were well defined with a polyphasic approach when other features such as the number of spore nuclei, mating systems and nuclear behaviour were added. Antrodia includes homothallic to bipolar species, with uni- or binucleate spores and normal nuclear behaviour. Amyloporia includes bipolar to tetrapolar species, with uninucleate spores and heterocytic nuclear behaviour. Fibroporia has strong molecular support and includes tetrapolar species, with uninucleate spores and normal nuclear behaviour. Amyloporia nothofaginea is described as a new species and two new combinations in Amyloporia are proposed. A key to the Antrodia s.l. species present in Patagonia is included.

A New Species

The genus Elaphropeza Macquart from the Oriental region is revised. In addition to the 79 known species (including seven new combinations of species previously placed within Drapetis Meigen) 51 new species are described and illustrated. The study is mainly based on freshly collected material in Singapore (544 samples, year cycle in eight stations and numerous hand captures). Smaller samples were available from Malaysia, Thailand and Cambodia. Of the 51 new species only 43 have been given a name: E. acantha sp. nov., E. asexa sp. nov., E. asiophila sp. nov., E. belumut sp. nov., E. benitotani sp. nov., E. bezzii sp. nov., E. bulohensis sp. nov., E. chekjawa sp. nov., E. combinata sp. nov., E. crassicercus sp. nov., E. darrenyeoi sp. nov., E. demeijerei sp. nov., E. equalis sp. nov., E. feminata sp. nov., E. flavicaput sp. nov., E. furca sp. nov., E. limosa sp. nov., E. luanae sp. nov., E. luteoides sp. nov., E. malayensis sp. nov., E. meieri sp. nov., E. melanderi sp. nov., E. modesta sp. nov., E. monacantha sp. nov., E. monospina sp. nov., E. murphyi sp. nov., E. neesoonensis sp. nov., E. ngi sp. nov., E. pauper sp. nov., E. pluriacantha sp. nov., E. riatanae sp. nov., E. sime sp. nov.,E. singaporensis sp. nov., E. singulata sp. nov., E. sivasothii sp. nov., E. spicata sp. nov., E. spiralis sp. nov., E. sylvicola sp. nov., E. temasek sp. nov., E. tiomanensis sp. nov., E. ubinensis sp. nov., E. yangi sp. nov., E. yeoi sp. nov. Eight species known only as females are briefly diagnosed but not named. Species (including type materials in most cases) described by C.R. Osten-Sacken, M. Bezzi, J.C.H. de Meijere, R. Senior-White, A.L. Melander and K.G.V. Smith were examined and re-described. Neotypes have been designated for E. calcarifera Bezzi, E. melanura Bezzi, E. formosae Bezzi and E. scutellaris Bezzi. Elaphropeza exul Osten-Sacken, 1882 is transferred as Crossopalpus exul (Osten-Sacken) comb. nov. Elaphropeza formosae Bezzi sensu Quate, 1960 re-described by L.W. Quate from Micronesia, is considered a new species and a new name is given: E. quatei sp. nov. All species of Elaphropeza are divided into two main species groups: E. biuncinata group and E. ephippiata group. Phylogenetic relationships within Elaphropeza are provisionally outlined. Some interesting morphological features and phenology of the species are discussed. Fourteen species have been found exclusively in mangroves. A key is given to the species of the Oriental Region (Indian subcontinent, Southeast Asia, Philippines and Taiwan, but excluding certain species of the Chinese mainland that proved to be different from the rest of the Oriental Region). A check list of the Oriental species is provided.

A New Species

BackgroundThe colubrid snakes of the genusRhynchocalamusare seldom studied and knowledge of their ecology and life history is scarce. Three species ofRhynchocalamusare currently recognized,R. satunini(from Turkey eastwards to Iran),R. arabicus(Yemen and Oman), andR. melanocephalus(from the Sinai Peninsula northwards to Turkey). All are slender, secretive, mainly nocturnal and rare fossorial snakes. This comprehensive study is the first to sample all knownRhynchocalamusspecies in order to review the intra-generic phylogenetic relationships and historical biogeography of the genus.MethodsWe revised the systematics ofRhynchocalamususing an integrative approach and evaluated its phylogeography. The phylogenetic position within the Colubridae and the phylogenetic relationships within the genus were inferred using 29 individuals belonging to the three known species, with additional sampling of two other closely-related genera,MuhtarophisandLytorhynchus. We analysed three mitochondrial (12S,16S, cytb) and one nuclear (c-mos) gene fragments. Phylogenetic trees were reconstructed using maximum likelihood and Bayesian inference methods; the latter method also used to provide the first time-calibrated molecular phylogeny of the genus. We generated a nuclear network and carried out a topology test and species delimitation analysis. Morphological comparisons were used to differentiate among species and to describe a new species from Israel. The studied material was comprised of 108 alcohol-preserved specimens, 15 photographs, and data from the literature for the examination of 17 mensural, 14 meristic, and two categorical characters.ResultsThe molecular results supportRhynchocalamusas monophyletic, and as having split from its sister genusLytorhynchusduring the Late Oligocene. The three recognized species ofRhynchocalamuscomprise four independently evolving groups. The molecular results reveal that the genus began to diverge during the Middle Miocene. We revealed that the best-studied species,R. melanocephalus,is paraphyletic. A population, formally ascribed to this species, from the Negev Mountain area in southern Israel is phylogenetically closer toR. arabicusfrom Oman than to the northern populations of the species from Israel, Syria and Turkey. Herein we describe this population as a new species:Rhynchocalamus dayanaesp. nov.DiscussionWe identify four species withinRhynchocalamus:R. satunini, R. arabicus, R. melanocephalus, andR. dayanaesp. nov., the latter, to the best of our knowledge, is endemic to southern Israel. The onset ofRhynchocalamusdiversification is very old and estimated to have occurred during the Middle Miocene, possibly originating in the Levant region. Radiation probably resulted from vicariance and dispersal events caused by continuous geological instability, sea-level fluctuations and climatic changes within the Levant region.

A new Tardigrada species, Claxtonia goni sp. nov. is described from specimens collected in the central area of the Haleakalā National Park, the island of Maui, Hawaii, U.S.A. The new species and Clx. pardalis (Degma & Schill, 2015) together with several examples of Clx. wendti (Richters, 1903) are the only known Claxtonia species with the plates having an intracuticular pattern resembling that on a leopard’s fur. Claxtonia goni sp. nov. differs from Clx. pardalis in the absence of pores on leg plates, in smaller and uniform pores on dorso-lateral plates, in very unequally spaced teeth in the dentate collar, in lesser ratio of internal cephalic cirrus and lateral cirrus A lengths, and in relatively shorter claws in fourth pair of legs. The differences between the new species and the other congeners as well as Echiniscus species with the same cirri composition and similar cuticular sculpture are also defined. The diagnosis of the genus Claxtonia is amended and three Echiniscus species are transferred into the genus with the proposed new combinations: Claxtonia aliquantilla (Grigarick, Schuster & Nelson, 1983) comb. nov., Clx. mosaica (Grigarick, Schuster & Nelson, 1983) comb. nov. and Clx. nigripustula (Horning, Schuster & Grigarick, 1978) comb. nov..

A New Species

The taxonomy and distribution of Pacific Annonaceae are reviewed in light of recent changes in generic delimitations. A new species of the genus Monoon from the Solomon Archipelago is described, Monoon salomonicum I.M.Turner & Utteridge sp. nov., together with an apparently related new species from New Guinea, Monoon pachypetalum I.M.Turner & Utteridge sp. nov. The confirmed presence of the genus in the Solomon Islands extends the generic range eastward beyond New Guinea. Two new species of Huberantha are described, Huberantha asymmetrica I.M.Turner & Utteridge sp. nov. and Huberantha whistleri I.M.Turner & Utteridge sp. nov., from the Solomon Islands and Samoa respectively. New combinations are proposed: Drepananthus novoguineensis (Baker f.) I.M.Turner & Utteridge comb. nov., Meiogyne punctulata (Baill.) I.M.Turner & Utteridge comb. nov. and Monoon merrillii (Kaneh.) I.M.Turner & Utteridge comb. nov. One neotype and four lectotypes are designated. The geographic patterns exhibited by nine native Annonaceae genera, that range in the Pacific beyond New Guinea, are discussed.
