A New Species

Recently, the status of a new species of atyid shrimp from Pohnpei (Micronesia) was discussed in relation to C. brachydactyla De Man, 1908 and C. mertoni J. Roux, 1911. By combining morphological data with a phylogenetic analysis with closely related species, this species is here described as Caridina variabilirostris sp. nov. Notes on its ecological distribution are also provided. The new species is characterized by a highly variable rostrum and is present in rivers all over Pohnpei Island. The status of this new species is clarified and it is shown that neither C. brachydactyla De Man 1908 nor C. mertoni J. Roux, 1911 occur on Pohnpei Island.

A New Species

A new species belonging to Lactarius subg. Plinthogalus was discovered during a long-term project on the diversity of Korean Lactarius. This species is proposed here as Lactarius cucurbitoides. The status of L. cucurbitoides as a new species is supported by molecular data and morphological features. Phylogenetic analysis based on internal transcribed spacer (ITS) sequences shows that L. cucurbitoides is closely related to L. subplinthogalus, L. friabilis, and L. oomsisiensis, with pairwise distances of 2.8–4.3%. Morphological characters of L. cucurbitoides that distinguish it from these closely related species are a pale yellow to pale orange colored pileus and non-discoloration of white latex. The new species is described and illustrated in the present paper.

A New Species

During field trips to Guam and Babeldaob Islands in Micronesia, freshwater shrimps were sampled and assigned either to Caridina brachydactyla De Man, 1908 or C. mertoni J. Roux, 1911 (Decapoda: Atyidae), following previous inventories. In combining morphological data with a genetical analysis, it appeared that all the specimens belonged to a new species, Caridina variabilis sp. nov., here described with its distribution. The status of this new species is clarified and finally, neither C. brachydactyla, nor C. mertoni occur in these two islands. DNA sequences of 16S were obtained from the syntypes of C. mertoni.

A New Species

We describe a new species of poison frog from Amazonian Peru. Dendrobates uakarii, sp. nov. is distinguished by the presence of paired parallel dorsolateral lines: one yellow oblique lateral and one red dorsolateral (on each flank), with one vertebral line, similar in color to the dorsolateral lines. Phylogenetic analysis show that D. uakarii, sp. nov. and closely related taxa (D. ventrimaculatus sp. aff. Shreve from Porto Walter, Brazil and another from Amazonas, Brazil) form the sister group to D. fantasticus Boulenger. This new species can be distinguished from its sister taxa on the basis of 19 unique mitochondrial gene nucleotide site substitutions. Comparisons between closely related species show a slight difference in call repetition rate and mean frequency.

A new species, Ceratophysella stachi, from Denmark, Germany, Luxembourg, Norway, Poland, and Ukraine is described based on morphological data and DNA barcodes. It belongs to a small European group of species with type B chaetotaxy and strong tegumentary granulation with distinct fields of coarse granules: C. granulata Stach, 1949, C. lawrencei (Gisin, 1963), C. neomeridionalis (Nosek & Červek, 1970), C. scotica (Carpenter & Evans, 1899), and C. silvatica Rusek, 1964. It differs from all of them in the chaetotaxy of lateral parts of thoracic terga II–III (setae m6 present and one additional seta outside lateral sensillum m7 present or absent) that is exceptional within the whole C. armata-group. Notes on closely related species C. granulata are also given.

AbstractAeolothrips iranicus sp. n. is described and illustrated from Fars Province, south of Iran. This is the twenty first species of the genus from Iran and in contrast to most species described in the genus Aeolothrips Haliday is bicolored. The status of the new species in comparison to apparently closely related species including A. collaris Priesner, A. pulcher Oettingen, A. tauricus Derbeneva and A. montivagus Priesner is discussed. Moreover, it is shown that the spermatheca of A. iranicus and A. collaris are different.

A new poroid fungus, Nigrofomes submelanoporus, from tropical China, is described and illustrated based on morphological characteristics and phylogenetic analysis. The new species is characterized by perennial, resupinate to effused-reflexed, woody-hard and dark gray to almost black basidiocarps, lacerate dissepiments, a monomitic hyphal system, the presence of cystidioles and hyphal pegs, and broadly ellipsoid basidiospores (4–5.1 × 3.1–4.3 µm). Molecular analysis based on ITS sequences demonstrates the phylogenetic position of the new species in Nigrofomes. The discriminating characteristics between the new species and closely related species are discussed.

AbstractThe Aschistodesmini from the Solomon Island are reviewed. Besides clarifying notes on the status of the type and closely related species of Aschistodesmus, descriptive notes and illustrations of the gonopods of the Solomon species of this genus, particularly of those published by Chamberlin, 1920, under the generic name of Solomonosoma, are given. Two new species, A. spatulifer and A. tridentifer are described, and a key to the species is provided. From Rennell Island Dorcadogonus modestus gen. n., sp. n. is described.

A new species, Pseudodactylaria brevis, is described, illustrated and compared with other Pseudodactylaria and Dactylaria-like taxa. Evidence for the new species is provided by morphological comparison and sequence data analyses. Pseudodactylaria brevis can be distinguished from other Pseudodactylaria and Dactylaria-like species by its short hyaline conidiophores and fusiform, 1-septate hyaline conidia. Phylogenetic analysis of LSU and ITS sequence data was carried out to determine the phylogenetic placement of the species and confirm the taxonomic status of Pseudodactylariaceae.
