A new species of wood lizard (Hoplocercinae, Enyalioides) from the Río Huallaga Basin in Central Peru

We report the discovery of a new species of Enyalioides from the premontane forest of the Río Huallaga basin in central Peru. The most similar and phylogenetically related species are E. binzayedi and E. rudolfarndti. However, the new species differs from E. binzayedi (state of character in parentheses) by having dorsal scales strongly keeled on paravertebral region and feebly keeled or smooth elsewhere (prominent medial keel on each dorsal scale), more dorsals in transverse row between dorsolateral crests at midbody 26–39, x̄ = 30.44 (22–31, x̄ = 27.57), and a conspicuous posteromedial black patch in the gular region of males (absent). Contrarily, adult males of the new species and E. rudolfarndti are readily distinguished by having a conspicuous posteromedial black patch in the gular region, absent in E. rudolfarndti, and by lacking a conspicuous orange blotch (faint if present) on the antehumeral region, as in E. rudolfarndti. We also present an updated molecular phylogenetic tree of hoplocercines, which strongly supports both referral of the newly discovered species to Enyalioides and its status as distinct from those recognized previously.

A New Species

The genus Linum consists of 15 species in Iran. A new species as well as a new record from Iran is described and illustrated here as L. khorassanicum and L. turcomanicum, respectively. The original description of the latter species is incomplete and ambiguous, probably due to incomplete taxon sampling. In this work, after a comprehensive taxon sampling from the entire distribution range of the species in northeast of Iran, the taxonomic description of L. turcomanicum is completed. The present study considers morphological and molecular (the nrITS region) analyses of the both species. In phylogenetic analysis based on the molecular data, we included these species and some related Linum species to examine the phylogenetic relationship of the new species and L. turcomanicum with other members of the genus. Linum turcomanicum is morphologically almost similar to L. austriacum and L. perenne, but it can be distinguished from them on the basis of several traits such as fruiting-pedicel form and length of petal. Likewise, results obtained from the molecular phylogenetic tree are consistent with those obtained from the morphological data. Linum khorassanicum is well characterized morphologically by having erect fruiting pedicels and inflorescence with few flowers. Our results suggest that the morphological data are in agreement with the molecular phylogenetic tree in which the taxonomic status of L. khorassanicum is confirmed as a new species. Based on IUCN Red List categories and criteria, L. khorassanicum and L. turcomanicum are evaluated as Endangered and Near Threatened species, respectively.

Gerhardtia sinensis, as a new species discovered from southern China, is described, illustrated and compared with morphologically similar and phylogenetically related species. Morphologically, it is characterized by its white to yellowish or partially pale yellow pileus with faint striae, subdistant to fairly distant lamellae with intervenose veins, and slightly verruculose basidiospores (4.7–)5.2–6.2(–6.6) × (2.5–)3.0–3.4(–3.8) μm in size. Molecular phylogenetic analyses of the new species and related taxa are performed based on the sequences of nuclear ribosomal large subunit (nrLSU) and nuclear ribosomal internal transcribed spacer (ITS).

The genus Trichoglossum (Geoglossaceae) is characterized by black, clavate, stipitate apothecia with hymenial setae. We collected T. cf. octopartitum from China and a new species of Trichoglossum from Thailand, the latter named as T. septatum. According to morphological examination and molecular phylogenetic analyses of ITS sequence data, T. septatum diverges from other Trichoglossum species. Full descriptions, colour figures, and a phylogenetic tree to show the positions of T. cf. octopartitum and T. septatum are provided, and the two species are compared with allied taxa. The important morphological characteristics of Trichoglossum species are also summarized.

Sorbus dolichofoliolatus (Rosaceae) sp. nov. from Yunnan Province, China, is described and illustrated based on the collections deposited at the herbarium CDBI. The new species is similar to S. rehderiana in infructescence with sparsely rust-brown short hairs, fruit size, and glabrescent leaflets, but the former has longer and wider leaflets, persistent stipules and pinkish fruit color. A molecular phylogenetic analysis supports that the new species is distinguishable from related species in the genus.

A New Species

A new species of axiid was discovered during sampling offshore deep banks on the middle continental shelf off Louisiana. Paraxiopsis kensleyi n. sp. appears to inhabit interstices and cavities of coralline algal rubble, rhodoliths, coral rubble, and other eroded calcareous substrates. Weakly separated from Eutrichocheles Wood-Mason, 1876 on the basis of morphology, present assignments of western Atlantic species to Paraxiopsis de Man, 1905 are regarded as provisional. The new species is described morphologically, and the coloration of freshly captured specimens is documented and compared to related species where possible. Coloration readily distinguishes mature specimens of the new species from Paraxiopsis spinipleura Kensley, 1996, with which it was initially confused. The diagnosis includes GenBank accession numbers for COI sequences to allow future molecular phylogenetic comparisons. Compared to regional species that share a similar dentation or spination on the submedian carina, the pleon of the new species is distinctive in the truncate ventral margin on pleura 2–4, as opposed to being broadly rounded or directed ventrally in an acutely triangular tip. The new species is the eighteenth species of Paraxiopsis worldwide and the ninth from western Atlantic waters, seven of which are now known to range into the Gulf of Mexico. An updated key to western Atlantic members of the genus is provided.

Rubia hangii, a new species of Rubia sect. Oligoneura from Guangxi Province, China, is described and illustrated. The placement of this species within Rubia is assessed based on a molecular phylogenetic analysis and morphological comparisons with related species. The new species is morphologically similar to R. siamensis and R. falciformis, but differs from the two taxa in having membranous to thin papery leaf blade, margins flat , slender petiole (< 1 mm wide), ovate-lanceolate stipule, triangular corolla lobes, fruit glabrous, with 1 ovule often aborted and 1 mericarp developed, rarely with 2 mericarps. Molecular phylogenetic analyses suggested that R. hangii is closely related to R. argyi and R. pallida. Rubia hangii can be easily distinguished from R. argyi and R. pallida based on leaf and stipule arrangement, leaf shape, number of principal veins, inflorescence position and flower shape.

Males And Females

A Ruehmaphelenchus species was isolated from an ambrosia beetle, Euwallacea fornicates, during a biodiversity survey of entomophilic nematodes in Taichung, Taiwan. The new species is characterised by a unique tail morphology in both males and females, and a unique spicule morphology in males. The male spicule has clear dorsal and ventral limbs (connected by a blade-like cuticle), a triangular membrane-like structure on its sides, and short, conspicuous, laterally oriented, projections at the distal end. In a molecular phylogenetic tree, inferred from near-full-length small subunit (SSU: 18S) and D2/D3 expansion segments of the large subunit (LSU: 28S) of ribosomal RNA, the new species and other nominal and undescribed Ruehmaphelenchus species formed a well supported clade within Bursaphelenchus. Although this result supports a previous study that suggested that Ruehmaphelenchus is a junior synonym of Bursaphelenchus, the generic relationship between Ruehmaphelenchus and Bursaphelenchus remains somewhat uncertain. Therefore, R. formosanus n. sp. is described as a member of Ruehmaphelenchus, although this should be regarded as a tentative placement.

A new species of the genus Sovia Evans, 1949, viz. S. liuzihaoi Huang & Fan sp. nov. is described from Mt. Ailao, Xinping Yi and Dai Autonomous County, representing a remarkable geographically southward extension of this genus in Yunnan Province, Southwestern China.
