Two New Species

The blindsnake genus Anilios (formerly Ramphotyphlops) is the largest and most diverse genus of snakes in Australia with 45 currently recognized species. Recent molecular genetic studies of the genus have identified high levels of cryptic diversity within many taxa, suggesting true species diversity is greatly underestimated. Anilios leptosoma is a slender blindsnake endemic to the mid-west of Western Australia. Although morphological variation has been identified within the species in the past, the systematics and true diversity remained unstudied. Here we use recent molecular data to guide a reappraisal of morphology in order to provide a taxonomic revision of the A. leptosoma species complex. We redescribe A. leptosoma and describe two new species that occur to the south of most of true A. leptosoma’s distribution: A. systenos sp. nov. and A. obtusifrons sp. nov. Anilios systenos sp. nov. is known from the Geraldton region with the furthest record only 100 km to the north-east, a very small range for a species of snake. Anilios obtusifrons sp. nov. has an even smaller distribution, as it is only known from a small coastal area south of Kalbarri and may represent a range-restricted taxa. All species are genetically divergent from each other and can be distinguished by consistent morphological characteristics, including the shape of the snout, the termination point of the rostral cleft and number of mid-body scale rows and ventral scales.

Crangonyx ephemerus n. sp. and Crangonyx pseudoephemerus n. sp. are described from the headwaters of the St. Marks River in Leon County, Florida, based on detailed morphological and molecular comparisons with the closely related species Crangonyx floridanus Bousfield, 1963. The morphological and molecular data, including three species delimitation models, lend support to the hypothesis that the taxon C. floridanus sensu lato represents a species complex. Diagnostic morphological characteristics are highlighted and discussed within this group to assist in future morphological analyses.

Two New Species

A complete taxonomic revision of the genus Anthothela (Anthothelidae) and closely related taxa is presented herein, based on original type material of nominal species and additional specimens from multiple deep-water surveys. A multi-disciplinary approach was used, combining morphological characteristics such as colonial branching patterns, polyp structure, and sclerite form and arrangement, together with phylogenetic reconstructions using two mitochondrial gene regions (mtMutS and igr1–cox1). The genus Anthothela, with seven nominal species globally, is here divided into four genera, two of which are new. Three of the original species of Anthothela are validated (A. grandiflora Sars, 1856, A. pacifica Kükenthal, 1913 and A. tropicalis Bayer, 1961), Spongioderma (?) vickersi Benham, 1928 is reassigned to Anthothela and two new species, A. aldersladei and A. quattriniae, are described. Anthothela argentea Studer, 1894, A. macrocalyx (Nutting, 1911) and A. nuttingi Bayer, 1956 are reassigned to Victorgorgia López-González & Briand, 2002 and two new species of this genus, V. eminens and V. nyahae are described. A new family, Victorgorgiidae is described for Victorgorgia due to clear morphological and genetic differences from Anthothela, the type genus of Anthothelidae. A new genus, Williamsium (Anthothelidae), is described for A. parviflora Thomson, 1916 which is restricted to South African waters. A number of North Atlantic Ocean specimens that have traditionally been mistaken for Anthothela grandiflora were found to be synonymous with Alcyonium grandiflorum (Tixier-Durivault & d'Hondt, 1974) and a second new genus, Lateothela (Anthothelidae), is erected for these specimens based on morphological and molecular evidence that Alcyonium grandiflorum was incorrectly placed in the genus Alcyonium Linnaeus. There is good congruence between morphological characteristics and molecular data at a generic level but at a species level, the degree of congruence was inconclusive as morphological and genetic variation is very low. Anthothela and Lateothela n. gen. are found to be closely related to some nominal Alcyonium species, and the family Anthothelidae and subfamily Anthothelinae are shown to be paraphyletic. These are the first records of Anthothela and Victorgorgia from Australian waters.

The aim of this study is to conduct a detailed taxonomic revision of the Poecilimon (Poecilimon) zonatus species-group (Orthoptera: Phaneropterinae) using both morphology and bioacoustics. Two new species (Poecilimon (Poecilimon) salmani, P. (P) azizsancar) and one new subspecies (P. (P) zonatus datca) are described. Based on the data, we conclude that the species complex can be separated into two subgroups (P. tauricola and P. zonatus). Within the P. zonatus subgroup, song structures indicate P. variicercis as basal branch since producing two syllable types is possibly a derived character. From both, from bioacoustics and morphology, it is concluded that the relationships between species of the group are as follows: P. tauricola subgroup (P. tauricola + P. azizsancar) + P. zonatus subgroup (P. variicercis + (P. varicornis + (P. zonatus zonatus+P. zonatus datca)) + (P. salmani+P. vodnensis)))). Except for two species (P. vodnensis and P. varicornis), the other species of the group are all distributed in Anatolia. P. vodnensis is known only from Macedonia, whereas, P. varicornis has been recorded only from Syria and Lebanon. We assume that the group originated from an Anatolian ancestral stock and expanded its distribution to the Balkans through Taurus Way and Dardanelles. Other ancestral populations may have also spread in the north-south directions through the appropriate steppe corridors in the Anatolian Diagonal Mountains and in its vicinity.

Two New Species

Two new species of Perenniporia, P. pseudotephroporasp. nov. and P. subcorticolasp. nov., are introduced respectively from Brazil and China based on morphological characteristics and molecular data. Perenniporia pseudotephropora is characterised by perennial, pileate basidiocarps with distinctly stratified tubes, grey pores, tissues becoming dark in KOH, a dimitic hyphal system with slightly dextrinoid arboriform skeletal hyphae and broadly ellipsoid to subglobose, truncate, weakly dextrinoid, cyanophilous basidiospores, measuring 4.9–5.2 × 4–4.8 μm. Perenniporia subcorticola is characterised by resupinate basidiocarps, yellow pores with thick dissepiments, tissues becoming dark in KOH, flexuous skeletal hyphae, ellipsoid, truncate and slightly dextrinoid basidiospores, measuring 4.2–5 × 3.5–4.2 µm. The morphologically-similar species and phylogenetically closely-related species to the two new species are discussed.

Two new species of Dentipellis are described from China based on morphological characteristics and molecular data. Dentipellis longiuscula is characterized by annual, resupinate hydnoid basidiomata with moderately long spines, rough basidiospores (5–6 × 3–3.6 µm) and absence of gloeoplerous hyphae and gloeocystidia. Dentipellis tropicalis is characterized by hydnoid basidiomata with numerous gloeocystidia presenting in hymenium, and minutely rough basidiospores (5–5.5 × 2.5–3.2 µm). Phylogenetic analysis based on the internal transcribed spacer (ITS) and nuclear large subunit ribosomal (nLSU) RNA gene regions confirmed the affinity of the new species in Dentipellis and indicated their relationships with other species in the genus.

The taxonomy of the genus Ophiocoma was last revised by Devaney in 1970. Recent discoveries of new species and re-instatement of previously synonymized names suggest that we still do not fully understand the species limits in this genus. A recent biodiversity survey of the SW Indian Ocean shallow reefs strongly suggested an unrecognised species in the genus, closely related to O. brevipes/O. dentata. This study examined both the molecular phylogenetic relationships and the morphological characteristics of several species in the genus in order to characterise the unrecognised species. The focal species clusters with O. brevipes, O. dentata, O. doederleini within a monophyletic clade supported by molecular data for the first time. The name Breviturma subgen. nov. is proposed for this clade, previously known as brevipes group. Type material of nominal species that have been synonymized with O. dentata was examined and re-assessed. Ophiocoma marmorata proved not conspecific with O. dentata. A rarely used character, dorsal disc granule density, was tested and showed differences between the examined species at similar sizes. In combination with colour pattern, disc granule density, arm spine sequence and maximum disc size, the new species was delimited morphologically and described as Ophiocoma krohi sp. nov.

Original Species

The Pteris cadieri complex is widely distributed in South and East Asia. Due to tremendous morphological variation within and between taxa, previous taxonomic treatments have been plagued with an element of uncertainty. In this study, the morphological characteristics, along with data from previous studies on reproductive modes, cytology, and genotypes, are integrated to clarify and delineate each taxon. Nine taxa are recognized in the Pteris cadieri complex: three original species (P. cadieri, P. hainanensis and P. grevilleana), one reinstated name (P. dimorpha, synonymized under P. cadieri), two new species (P. incurvata sp. nov. and P. perplexa sp. nov.), two new varieties (P. dimorpha var. prolongata var. nov., and P. dimorpha var. metagrevilleana var. nov.), and a forma (P. grevilleana f. ornata stat. nov.). The lectotypes of P. cadieri, P. dimorpha, P. grevilleana, and P. hainanensis are designated. Each taxon is described in detail. A key is provided to facilitate the identification of all taxa.
