Many Isaria-like species have recently been moved into more appropriate genera. However, more robust molecular phylogenetic analyses are still required for Isaria-like fungi to ensure accurate taxonomic identification. We analyzed these Isaria-like strains using multi-gene phylogenetics. Cryptic diversity was discovered in several Isaria farinosa strains, and two new species, Samsoniella pseudogunnii and S. pupicola, are proposed. Our results reveal that more attention needs to be paid to cryptic intraspecific diversity across different isolates and genotypes of the Isaria-like species, some of which will need to be transferred to Samsoniella. Interestingly, S. hepiali, with a very broad host distribution, has been widely used as a medicinal and edible cordycipitoid fungus.

Gene Sequence Data

Coloration, gene-sequence data (H3, 12s, 16s), and subtle features in morphology support the description of two new species, both formerly regarded to represent accepted variants of Phimochirus holthuisi s.l. While color in life consistently separates these species from P. holthuisi s.s. and from each other, morphological distinctions are subtle and less than absolute in small specimens, being based on ventral spine counts of walking leg dactyls and relative development of the superior crest on the major chela. Molecular phylogenetic analyses clearly support the separation of sister clades, representing two new species, from P. holthuisi s.s. as well as other congeners available for analysis. Both of the new species are presently known to occur widely throughout the northern Gulf of Mexico, though one occurs more commonly in the northeastern and southeastern Gulf, and may range as far south as Suriname. The other has been taken primarily in the northwestern Gulf, and is not known from outside Gulf waters. While both of the new species appear restricted to relatively deep subtidal waters of the continental shelf, Phimochirus holthuisi s.s. is instead more commonly found in shallow nearshore tropical waters on or near coral reefs. Previous literature reports of P. holthuisi usually represent, at least in part, one or both of these two new species.

Molecular Characters

Two new species of Pythium, namely P. subinflatum and P. xuzhouense, from soybean (Glycine max) in southern China are described based on their morphology and molecular phylogenetic analyses inferred from the internal transcribed spacer region of the ribosomal RNA gene and mitochondrial cytochrome c oxidase subunit I gene. Pythium subinflatum is characterized by globose to sub-globose or ovoid hyphal swellings, filamentous inflated sporangia, smooth oogonia, mostly diclinous antheridia, elongated along the oogonial stalk, subcircular, subglobose or fist-shaped antheridial cells, and aplerotic and slightly thick-walled oospores (2–3.5 µm); P. xuzhouense differs from other species in the genus by filamentous or lobulated sporangia, smooth oogonia, mostly diclinous, sometimes monoclinous antheridia, subclavate, falcate or semicircle to subcircular antheridial cells, and plerotic or nearly plerotic and thin-walled oospores (0.5–1.5 µm). In addition, the two new species are compared to closely related Pythium species regarding their phylogenetic positions and morphological features.

Guepinia alba sp. nov. and G. shanxiense sp. nov. are described and illustrated from Northern China in this paper. Morphologically, G. alba is distinguished from other Guepinia species by whitish basidiomata and 4-spored basidia while G. shanxiense is diagnosed by reddish orange basidiomata and ellipsoid to oblong ellipsoid basidiospores. Molecular phylogenetic analyses based on ITS and nrLSU sequences support the establishment of the two new species.

A New Species

A recent molecular phylogenetic revision of the snake-eyed skinks (genus Panaspis Cope, 1868) uncovered extensive cryptic diversity, including several new species from throughout sub-Saharan Africa. Here, we describe one of these from Ethiopia as Panaspis annettesabinae sp. nov. This description is based on a previous molecular phylogeny and morphological, scalation, and coloration data collected from the type specimen. Phylogenetic analyses place the species alone in what we term the P. annettesabinae species group from Ethiopia. This group forms the sister lineage to a large southern African radiation and suggests a potential northern origin for much of the extant diversity of Panaspis. Many new taxa have recently been discovered in the genus and region, and there are several historical records of Panaspis from elsewhere in Ethiopia. Thus, we suggest that the range of this new species (known only from a single specimen at present) may be much larger, and that additional undescribed species may exist in northern sub-Saharan Africa.

Two new truffle species Barssia guozigouensis and B. luyashanensis are described and illustrated from North China based on morphological and molecular evidences. Morphologically, B. guozigouensis is diagnosed by its distinctly warty ascomata and solid gleba with small and irregular chambers, and B. luyashanensis is by its red brown ascomata with fine warts and gleba without chambers. Molecular phylogenetic analyses based on the ribosomal internal transcribed spacer region and 28S large subunit nrDNA supported the placement of the new species.

We describe two new species of the annelid genus Trilobodrilus Remane, 1925 (Dinophilidae Verill, 1892) from an intertidal and a subtidal location in San Diego, California. These two species show morphological and molecular divergences between each other and the previously described, geographically distant species. Intertidal T. windansea sp. nov. differs from subtidal T. ellenscrippsae sp. nov. most remarkably in the number and pattern of ciliary tufts and bands on the prostomium and along the body length, besides showing ca 15% difference in gene fragments of COI and CytB. Trilobodrilus windansea sp. nov., though nesting with T. ellenscrippsae sp. nov. in the molecular phylogenetic analyses, morphologically resembles the Japanese T. itoi Kajihara, Ikoma, Yamasaki & Hiruta, 2015 most closely, but still differs from this species in the higher number of apical ciliary tufts, an additional ciliary row posterior to the second ciliary band, and by lacking a forth ciliary band and segmentally arranged lateral ciliary tufts. Trilobodrilus ellenscrippsae sp. nov. is morphologically most similar to the Japanese T. nipponicus Uchida & Okuda, 1943, but is much shorter, has more apical ciliary tufts, and less regularly arranged lateral ciliary tufts along the body. All species differ significantly in all compared gene fragments, and no obvious correlation was found between habitat and the species morphology or relationships.

Indochina land snails of the family Ariophantidae are in need of thorough systematic revision. Here we comprehensively revise the systematics of the large-shelled, sinistral (counterclockwise) coiling snails from Thailand and Peninsular Malaysia. Molecular phylogeny based on mitochondrial (coi and 16S) and nuclear (28S) gene sequences demonstrates that these sinistral snails are not members of Dyakiidae as previously thought, but instead are more closely related to the genus Hemiplecta in the family Ariophantidae. Comparative morphology also reveals similarity of reproductive organ features (globular gametolytic organ, well-developed dart apparatus, and lack of amatorial organ complex). Based on this evidence, we propose to transfer these sinistral snails to the genus Hemiplecta. Molecular phylogenetic analyses further strongly support the monophyly of this sinistral lineage with respect to other members of Hemiplecta. This monophyletic clade consists of five members including three species that were previously classified as “Dyakia”, H. lahatensis, H. retrorsa and H. salangana, and two new species described herein, H. ligorica n. sp. and H. thailandica n. sp. This study also suggests that the anatomy of the gametolytic organ in the genus Hemiplecta corresponds well with the phylogenetic relationships and appears to be a taxonomically informative character, while the penial verge has little utility for generic recognition.

We describe and illustrate Zamia imbricata and Z. sinuensis, two new species (Zamiaceae, Cycadales) from the Magdalena-Urabá moist forests ecoregion of northern Colombia. The new species appear to belong to the manicata clade, an assemblage of species strongly supported by recent molecular phylogenetic analyses and which shares a set of morphological characters such as hypogeous to semi-hypogeous stems, distinctly toothed leaflets, long peduncles, megasporophylls with relatively flat shields, and diminutive pollen cones containing microsporophylls with a much-reduced fertile section of the lamina. Zamia imbricata, a species from the Middle Magdalena Valley Basin of Caldas, is distinguished from other members of the clade by its planar leaves comprised of diminutive, highly imbricate papyraceous leaflets. Zamia sinuensis, a species from the Sinú River Basin of Córdoba is similar to Z. manicata, from which it is distinguished by the absence of the petiolule and gland-like collar that characterize the latter, and by its strongly undulate leaflets. The two new species are discussed within the context of the manicata clade, and a vegetative key to the clade is provided.
