Three New Species

The current paper expands knowledge of the genus Coddingtonia Miller, Griswold & Yin, 2009. Based on morphological characters and molecular data, three species are documented as new to science: C. erhuan Feng & Lin, sp. nov. (♀) from China, C. lizu Feng & Lin, sp. nov. (♀) from China, and C. huifengi Feng & Lin, sp. nov. (♂♀) from Indonesia. The type of C. euryopoides Miller, Griswold & Yin, 2009 is also reexamined. DNA sequences (COI), detailed illustrations of habitus, male palp and epigyne are provided for these four species, as well as a key and a distribution map for Coddingtonia species.

Colour Dimorphism

Representatives of the Southeast Asian pholcid spider genus Uthina Simon, 1893 have been thought to be very homogeneous in their ecology and morphology. The 14 previously known species all inhabit near-ground microhabitats and cave entrances, and range from pale to dark brown in colour. Even their genitalia are partly very similar, with some species pairs being barely distinguishable based on morphological characters. Here we describe three new species from Bali, Java and Sulawesi that represent three further microhabitats and demonstrate considerable ecological and morphological diversity within the genus: U. maya, sp. nov. from Bali is a large dark species on tree trunks; U. hylobatea, sp. nov. from Bali and eastern Java is a pale leaf-dwelling species that exhibits colour dimorphism; and U. mimpi, sp. nov. is a pale troglomorphic species collected in the aphotic zones of two South Sulawesi caves. In addition, we present new data for five previously described species, including ultrastructure, natural history, new records, taxonomic notes and a description of the previously unknown female of Uthina khaosokensis Yao, Li & Jäger, 2014. Molecular data suggest that all previously described species are very closely related to each other (constituting the monophyletic luzonica-group), and that the three new species represent separate clades within the genus. However, the basal trichotomy could not be resolved: U. maya + (U. hylobatea + U. mimpi) + luzonica-group.

We diagnose and describe three new species of the primitively segmented spider genus Songthela from Guizhou Province, China, based on morphological characters and molecular data: S. liuisp. nov. (♂♀), S. tianzhusp. nov. (♂♀), and S. yupingsp. nov. (♂♀). We provide the genetic distances within and among the three new species based on the DNA barcode gene, cytochrome c oxidase subunit I (COI) to support our descriptions. We also provide the COI GenBank accession codes for the three new species for future identification.

Morphological And Molecular Data

The genus Onychelmis Hinton, 1941 was for a long time regarded as a small taxon with only three known species distributed in the Andes. A study of new material from Ecuador, using morphological and molecular data, has resulted in the discovery of five new species: Onychelmis lenkae sp. nov., O. lobata sp. nov., O. minor sp. nov., O. onorei sp. nov. and O. splendida sp. nov. We also revised the entire genus and redescribed the three known species, O. longicollis (Sharp, 1882), O. leleupi Delève, 1968 and O. whiteheadi Spangler & Santiago, 1991. Habitus photographs of adults are provided, together with line drawings of male and female genitalia, and schematic illustrations of the distribution of femoral tomentum for each species. DNA sequences for barcoding the COI mtDNA fragment were used to support species delimitation and to suggest possible relationships among species. The revision includes a key to adults of all species of Onychelmis and notes on the biogeography of the genus, with an updated distribution map.

A New Species

A new polypore, Rhodonia tianshanensis, collected from West Tianshan Nature Reserve in Xinjiang Autonomous Region (northwest China), is described and illustrated based on morphological characteristics and molecular evidence. It is characterized by having resupinate basidiomata with an oblique tube layer, fusoid cystidioles in the hymenium, and cylindrical basidiospores. Based on multiple loci DNA sequences including the internal transcribed spacer (ITS), the large subunit (nLSU), and the second subunit of RNA polymerase II (RPB2) regions, our phylogeny strongly supported R. tianshanensis as a new species belonging to the genus Rhodonia.

Three New Species

Abstract Bees of the tribes Biastini, Neolarrini, and Townsendiellini are cleptoparasites in the subfamily Nomadinae (Hymenoptera, Apidae) and parasitize solitary bees. Understanding their phylogenetic relationships has proven difficult for many decades. Previous research yielded ambiguous results because of conflicting phylogenetic signals of larval and adult morphological characters. Molecular data settled some of this disparity but our knowledge remains fragmented due to limited taxon sampling and the discovery of a new lineage associated with Biastini: the enigmatic Schwarzia Eardley, 2009. Schwarzia has unusual morphological features and seems transitional between previously established taxa. This puts limits on our ability to diagnose the groups, understand their antiquity and biogeography, and study the evolution of host-choice. To address this, we integrate phylogenomics and morphology to establish a fossil-calibrated phylogeny for the tribes Biastini, Neolarrini, and Townsendiellini. We show that Schwarzia is indeed closely related to Biastes Panzer, 1806, but Biastes itself is paraphyletic in respect to Neopasites Ashmead, 1898, and even Biastini is paraphyletic due to Townsendiella Crawford, 1916, which is sister to Rhopalolemma Roig-Alsina, 1991. To ensure monophyly, we lower Neopasites to subgeneric rank within Biastes and resurrect Melittoxena Morawitz, 1873 as a third subgenus. We then assess the diagnosability of different tribal concepts and establish an expanded tribe Neolarrini that includes Biastini and Townsendiellini as new synonyms for Neolarrini. Neolarrini in this new, expanded sense likely originated in the Nearctic in the mid-Eocene and is, as far we know, composed exclusively of parasites of oligolectic hosts. Lastly, our continued efforts to find the rare Schwarzia in Eastern Africa led to the discovery of three new species, which are described herein.

Three New Species

The ‘acantherpestes’ group of dragon millipedes, formerly placed in the genus Desmoxytes Chamberlin, 1923, is revised and assigned to the new genus Nagaxytes Srisonchai, Enghoff & Panha gen. nov. Desmoxytes acantherpestes Golovatch & Enghoff, 1994 is the type species of the new genus and is redescribed as N. acantherpestes (Golovatch & Enghoff, 1994) gen. et comb. nov. Three new species are described from Thailand: N. erecta Srisonchai, Enghoff & Panha gen. et sp. nov. and N. gracilis Srisonchai, Enghoff & Panha gen. et sp. nov. from Kanchanaburi Province, and N. spatula Srisonchai, Enghoff & Panha gen. et sp. nov. from Tak Province. All new species are endemic to western Thailand and all are restricted to limestone habitats. Complete illustrations of external morphological characters, an identification key, and a distribution map are provided.

Three New Species

We consolidate and present data for the sexual stages of five North American species of Orphella, fungal members of trichomycetes previously classified within Harpellales. Three species emendations accommodate the newly recognized characters, including not only the coiled zygospores and accompanying cells but also other morphological traits not provided in the original descriptions for O. avalonensis, O. haysii, and O. hiemalis. We describe three new species, Orphella cataloochensis from both the Smoky Mountains in USA and two provinces in Canada as well as O. pseudoavalonensis and O. pseudohiemalis, both from the Cascade Range, in Oregon, USA. Key morphological features for all known species are summarized and reviewed, with illustrations of some of the North American taxa to update and supplement the literature. The entire suite of morphological characters is discussed, with emphasis on species relationships and hypotheses on possible vicariant origins. We also present a molecular phylogeny based on nuc rDNA 18S and 28S, which supports Orphella as a lineage distinct from Harpellales, and we establish a new order, Orphellales, for it. With the combination of sexual features, now known for 12 of the 14 species of Orphella, and new molecular data, the group is now better characterized, facilitating and hopefully also promoting future studies toward a better understanding of their relationships, origins, and evolutionary history as stonefly gut–dwelling fungi.

Three New Species

We describe three new species of minute salamanders, genusThorius, from the Sierra Madre del Sur of Oaxaca, Mexico. Until now only a single species,T. minutissimus, has been reported from this region, although molecular data have long shown extensive genetic differentiation among geographically disjunct populations. AdultThorius pinicolasp. nov.,T. longicaudussp. nov., andT. tlaxiacussp. nov. are larger thanT. minutissimusand possess elliptical rather than oval nostrils;T. pinicolaandT. longicaudusalso have longer tails. All three new species occur west of the range ofT. minutissimus, which has the easternmost distribution of any member of the genus. The new species are distinguished from each other and from other namedThoriusin Oaxaca by a combination of adult body size, external morphology and osteology, and by protein characters (allozymes) and differences in DNA sequences. In addition, we redescribeT. minutissimusand a related species,T. narisovalis, to further clarify the taxonomic status of Oaxacan populations and to facilitate future studies of the remaining genetically differentiatedThoriusthat cannot be satisfactorily assigned to any named species. Populations of all five species considered here appear to have declined dramatically over the last one or two decades and live specimens are difficult to find in nature.Thoriusmay be the most endangered genus of amphibians in the world. All species may go extinct before the end of this century.

Three New Species

The phylogeny of the Colocasiomyia cristata species group is reconstructed as a hypothesis, based on DNA sequences of two mitochondrial and six nuclear genes and 51 morphological characters. The resulting tree splits this species group into two clades, one of which corresponds to the colocasiae subgroup. Therefore, a new species subgroup named as the cristata subgroup is established for the other clade. Within the cristata subgroup, three subclades are recognized and each of them is defined as a species complex: the cristata complex composed of five species (including three new ones: C. kinabaluana sp. nov., C. kotana sp. nov. and C. matthewsi sp. nov.), the sabahana complex of two species (C. sabahana sp. nov. and C. sarawakana sp. nov.), and the xenalocasiae complex of five species (including C. sumatrana sp. nov. and C. leucocasiae sp. nov.). There are, however, three new species (C. ecornuta sp. nov., C. grandis sp. nov. and C. vieti sp. nov.) not assigned to any species complex. In addition, breeding habits are described for four cristata-subgroup species, each of which monopolizes its specific host plant. And, data of host-plant use are compiled for all species of the cristata group from records at various localities in the Oriental and Papuan regions. The evolution of host-plant selection and sharing modes is considered by mapping host-plant genera of each species on the phylogenetic tree resulting from the present study.
