A New Species

Peliosanthes crassicoronata is described and illustrated as a new species from southern Vietnam. It somewhat resembles P. macrostegia in having drooping bowl-shaped purplish flowers, but is readily distinguishable by the larger leaves with more numerous longitudinal veins, internally thickly ribbed staminal corona, and pistil with a hexagonal ovary and an indistinct style. The phylogenetic relationship of the new species was inferred from an analysis of chloroplast and nuclear DNA sequences.

A New Species

Aphids in the genus Hyalopterus Koch (Hemiptera: Aphididae) are pests of stone fruit trees in the genus Prunus globally, causing damage directly through feeding as well as transmission of plant viruses. Despite their status as cosmopolitan pests, the genus is poorly understood, with current taxonomy recognizing two, likely paraphyletic, species: Hyalopterus pruni (Koch) and Hyalopterus amygdali (Blanchard). Here we present a systematic study of Hyalopterus using a molecular phylogeny derived from mitochondrial, endosymbiont, and nuclear DNA sequences (1,320 bp) and analysis of 16 morphometric characters. The data provides strong evidence for three species within Hyalopterus, which confirms previous analyses of host plant usage patterns and suggests the need for revision of this genus. We describe a new species H. persikonus Miller, Lozier & Foottit n. sp., and present diagnostic identification keys for the genus.

A New Species

We describe a new frog species of the Spinomantis bertini species complex based on congruent genetic evidence from mitochondrial and nuclear DNA sequences as well as minor morphological differences. A molecular phylogeny derived from the mitochondrial 16S rRNA gene revealed that Spinomantis mirus sp. nov. is sister to a clade containing the other two described species of the species complex, S. bertini and S. beckei, but strongly differentiated from these two species by 8.1–9.8% pairwise distances in this gene. DNA sequences from two nuclear genes revealed that S. mirus sp. nov. shares no alleles with these two species. Phenotypically, S. mirus sp. nov. differs from the other species of the complex by its larger size and some aspects of its coloration, including clear mottling on the flanks, tri-color banding on the legs, and distinct brown dots on the dorsum. The new species is so far only known from Pic d’Ivohibe Special Reserve. Its distribution thus appears to not overlap with those of the other two species, which as far as known are restricted to the Andohahela Massif in the extreme South-East of Madagascar, at a distance of about 250 km from Ivohibe.

A New Species

Ottelia guanyangensis (Hydrocharitaceae), a new species from southwestern China, is described and illustrated. This aquatic plant is a perennial, submersed herb with bisexual flowers and a hexagonal-cylindric fruit. It is related to O. acuminata var. songmingensis and O. balansae but differs from these two taxa by its bisexual flowers, spathe with 2–5 flowers, trinerved leaf with obvious cross veins, and a winged, hexagonal-cylindric fruit. Molecular phylogenetic analysis based on nuclear DNA internal transcribed spacer (ITS) sequences and three chloroplast DNA sequences (rbcL, trnK5’ intron and trnS-trnG) resolves O. guanyangensis as a distinct clade, which further justifies its recognition as a new species.

A new species ofPerisesarma,P. tuerkayi, is described from mangroves of Tan Thoi Island, southern Vietnam. Morphologically, the new species differs most significantly from congeners by the tuberculation pattern of the chelar dactylus, its unique G1 morphology, an unusually large maximum body size, and relatively short and broad ambulatory legs. Genetically,P. tuerkayin. sp. is markedly divergent from other congeneric species, both in mitochondrial and nuclear DNA. It is the fifth species ofPerisesarmareported from Vietnam.

A New Species

A new species of the genus Megophrys is described from Guizhou Province, China. Molecular phylogenetic analyses based on mitochondrial DNA and nuclear DNA sequences all strongly supported the new species as an independent clade sister to M. minor and M. jiangi. The new species could be distinguished from its congeners by a combination of the following characters: body size moderate (SVL 43.4–44.1 mm in males, and 44.8–49.8 mm in females; vomerine teeth absent; tongue not notched behind; a small horn-like tubercle at the edge of each upper eyelid; tympanum distinctly visible, rounded; two metacarpal tubercles on palm; relative finger lengths II < I < V < III; toes without webbing; heels overlapping when thighs are positioned at right angles to the body; tibiotarsal articulation reaching the level between tympanum and eye when leg stretched forward; in breeding males, an internal single subgular vocal sac in male, and the nuptial pads with black spines on dorsal surface of bases of the first two fingers.

A New Species

Brevipalpus contains about 290 species, some of which are considered of economic importance. In spite of their agricultural importance, the species diversity is scarcely known in several regions around the world, notably on wild plants. In this work a new species collected on an endemic ivy of the Azores Archipelago, Hedera azorica Carrière (Araliaceae), is described based on an integrative approach using morphological traits of the adults, obtained through electron and light microscopy, and molecular characters based on mitochondrial and nuclear DNA sequences. Phylogenetic analyses were conducted in order to produce reliable phylogenetic placement of the new species, which is tentatively classified in the B. portalis species group. Morphological similarities between the new species and B. cuneatus Canestrini and Fanzago point out to some inconsistencies in the current morphological classification of Brevipalpus species, especially in the definition of the B. cuneatus group, herein discussed.

A New Species

During a survey of microfungi associated with palms from karst formations, three novel ascomycetes were found from decaying petioles of Trachycarpus fortunei (Arecaceae) in Guizhou, China. Multi-gene phylogenetic analyses based on a combined SSU, ITS, LSU, RPB2 and TEF1α sequence data showed that these collections were affiliated to Brunneofusispora and Neooccultibambusa in the family Occultibambusaceae. A new species Brunneofusispora inclinatiostiola is introduced. It is phylogenetically close to B. clematidis but represents a distinct lineage. Morphologically, it differs from the latter in having immersed ascomata with eccentric, periphysate ostiole and smaller ascospores. Morpho-phylogenetic evidence also revealed two new Neooccultibambusa species, N. kaiyangensis and N. trachycarpi. Together with the generic type N. chiangraiensis, they formed a distinct lineage within the genus Neooccultibambusa. Three novel palmicolous fungi of Occultibambusaceae are described, illustrated and notes on their identification are provided. The ecological significance of the new taxa and the phylogenetic relationship of genera in Occultibambusaceae is discussed.

A new species of the currently monotypic genus Fenerbahce is described from the eastern Congo Basin. It is distinguished from F. formosus from the western Congo Basin by several characters, of which the most prominent are: a more anterior origin of dorsal fin relative to anal fin, a deeper body, long extension on edges of the caudal fin, and a distinct colour pattern. The distinctness of the two species is supported by additional morphological characters and the results of a preliminary analysis of mitochondrial and nuclear DNA sequences.

Helicoön subglobosum sp. nov. from a decaying wood submerged in a freshwater stream at Juchi Town of Alishan area, Chiayi County, Taiwan, is described and illustrated with light and scanning electron micrographs. It differs from previously described species of Helicoön in having large subglobose conidia which are borne singly on very short conidiophores. The phylogenetic relationship of H. subglobosum and related taxa were sought by comparing the sequences of the ITS barcode and partial large subunit regions of the nuc rDNA. A synopsis of the 18 accepted species and a dichotomous key to the genus are given.
