A giant new species of Enchiridium (Polycladida, Prosthiostomidae) from southwestern Japan.

ABSTRACT: We describe a new species of polyclad flatworm, Enchiridium daidai sp. nov., from the rocky subtidal zone in the East China Sea along the coasts of the Kyushu and Okinawa Islands, Japan. Enchiridium daidai sp. nov. is characterized by i) the entire periphery of the dorsal surface narrowly fringed with orange, ii) a marginal-eyespot band extending to the position of the mouth (about anterior one-eighth of body), and iii) two prostatic vesicles covered by a common muscle sheath, which is penetrated by the ejaculatory duct. We performed a molecular phylogenetic analysis based on 945-bp 28S rDNA sequences of 16 species of Prosthiostomidae currently available in public databases in addition to those of E. daidai sp. nov. and Prosthiostomum torquatum Tsuyuki et al., 2019. In the resulting tree, our new species was nested in a clade composed of Enchiridium species. The tree topology was in favor of a taxonomic view that Enchiridium should be defined by having i) a common muscle sheath that encloses two prostatic vesicles and ii) marginal eyespots that may or may not surround the periphery of the dorsal surface.

A new species of Hedgpethia (Arthropoda, Pycnogonida, Colossendeidae) from southwestern Japan.

Project description:We describe Hedgpethia spinosasp. n. based on a single male specimen obtained from 197-207 m depth, south of Yaku Island, Kagoshima Prefecture, Japan. Among 15 previously known congeners, the new species resembles Hedgpethia bicornis (Losina-Losinsky & Turpaeva, 1958), Hedgpethia chitinosa (Hilton, 1943), and probably Hedgpethia brevitarsis (Losina-Losinsky & Turpaeva, 1958), in having a mid-dorsal tubercle on the posterior rim on each trunk segment. The new species, however, is distinguishable from those by a pair of horns on the anterior margin of the cephalic segment, spines on the first coxae, and denticulate spines on the strigilis. The new species represents the fifth member of the genus so far known from Japanese waters, in addition to Hedgpethia brevitarsis (Losina-Losinsky & Turpaeva, 1958), Hedgpethia chitinosa (Hilton, 1943), Hedgpethia dofleini (Loman, 1911), and Hedgpethia elongata Takahashi, Dick & Mawatari, 2007.

Description of a new species of Paraplehnia (Polycladida, Stylochoidea) from Japan, with inference on the phylogenetic position of Plehniidae.

Project description:We describe a new species of polyclad flatworm, Paraplehniaseisuiae sp. nov., from 298-310 m depths in the Sea of Kumano, West Pacific, Japan. Paraplehniaseisuiae sp. nov. is characterized by i) a developed muscular wall proximally occupying about one-third of the prostatic vesicle, ii) no common duct between the spermiducal bulbs and the prostatic vesicle, and iii) a genital pit between the male and female gonopores. We provide a partial sequence (712 bp) of the mitochondrial cytochrome c oxidase subunit I gene as a DNA barcode for the species. Our phylogenetic analyses based on 603-bp 28S rDNA sequences indicate that P.seisuiae sp. nov. is nested in a clade consisting of stylochoid species along with unidentified species of Stylochus. It suggests that Plehniidae belongs to Stylochoidea, although this should be confirmed by future studies that contain Plehniaarctica (Plehn, 1896), the type species of the type genus of the family. The interfamily relationship among the superfamily Stylochoidea remains poorly resolved.

A new species of Labidocera (Copepoda, Calanoida, Pontellidae) collected from Okinawa, southwestern Japan, with establishment of five Indo-West Pacific species groups in the L.detruncata species complex.

Project description:Labidocerachuraumi sp. n. is described from Okinawa, southwestern Japan. The female of the new species differs from other congeners in genital compound somite with right postero-lateral and left antero-lateral processes. The male is distinguished from other congeners by the structure of the fifth leg. This new species is assigned to a newly proposed species group, the Labidoceramadurae species group, within the Labidoceradetruncata species complex. In this species complex five Indo-West Pacific species groups are recognized (cervi, detruncata, gangetica, madurae, and pavo) and defined on the basis of difference in sexual dimorphism.

Dysosmavillosa (Berberidaceae), a new species from Guizhou, Southwestern China.

Project description:A new species, Dysosmavillosa Z.W.Wang & H.C.Xi, is described and illustrated based on collections from the Yueliang Mountains in Congjiang County of Guizhou, Southwestern China. It is morphologically similar to D.difformis (Hemsl. & E.H.Wilson) T.H.Wang ex T.S.Ying, but can be easily distinguished from D.difformis by its inflorescences bearing a greater number of flowers (5-13 vs. 2-5), white-villous stems, petioles, and abaxial leaf blade, and stigma dark purple-red. In addition, we also compare this new species to the three species of Podophyllum (i.e., P.glaucescens J.M.H.Shaw, P.hemsleyi J.M.H.Shaw & Stearn, and P.trilobulum J.M.H.Shaw) which are insufficiently known and listed as putative members of Dysosma in Flora of China. Dysosmavillosa can also be easily distinguished from P.glaucescens (7-flowered; to 40 cm tall) and P.hemsleyi (4-flowered; to 40 cm tall) by its inflorescences bearing a greater number of flowers, relatively smaller stature (9-23 cm tall), stems, petioles and abaxial leaf blade densely white-villose. Although the stems and petioles of P.trilobulum also possess fine short hairs, it can be easily distinguished from D.villosa by its trilobulate leaves, inflorescence with fewer flowers (2-5), and the position of inflorescence (inserted at or above midpoint on petiole of upper leaf).

Description of a New Species of the Marine Flatworm Prosthiostomum (Platyhelminthes: Polycladida) and its Three Known Congeners from Misaki, Japan, with Inference of Their Phylogenetic Positions within Prosthiostomidae.

Project description:The present study provides morphological descriptions of four species of Prosthiostomum (Polycladida, Prosthiostomidae)-P. auratum Kato, 1937; P. hibana sp. n.; P. cf. ostreae Kato, 1937; and P. vulgare Kato, 1938-based on specimens collected among branching coralline algae and kelp holdfasts in Misaki, Japan. The new species P. hibana sp. n. is characterized by i) the dorsal surface of the body covered with numerous orange maculae, some of which coalesce together to form larger ones; ii) a pair of linear cerebral-eyespot clusters, each consisting of relatively few (7-9) cerebral eyespots; iii) 3-4 pairs of ventral eyespots embedded in parenchyma: iv) the inner wall of the male atrium deeply ruffled; v) the lumen of the seminal vesicle being narrow and elongated in shape; and vi) a large sucker situated in the center of the body. We remark on some morphological characters that were not mentioned in the original description of P. auratum. We infer the phylogenetic positions of these four species within Prosthiostomidae using the maximum-likelihood analysis based on partial 28S rRNA and COI gene sequences determined de novo, in addition to those that are currently available in public databases. In the resulting tree, the four species-P. auratum, P. hibana sp. n., P. cf. ostreae, and P. vulgare-were nested in a clade that was composed of all the other Prosthiostomum species included in the analysis.

Four New Species of Hemileccinum (Xerocomoideae, Boletaceae) from Southwestern China.

Project description:The genus Hemileccinum belongs to the subfamily Xerocomoideae of the family Boletaceae. In this study, phylogenetic inferences of Hemileccinum based on sequences of a single-locus (ITS) and a multi-locus (nrLSU, tef1-α, rpb1, rpb2) were conducted. Four new species, namely H. abidum, H. brevisporum, H. ferrugineipes and H. parvum were delimited and proposed based on morphological and molecular evidence. Descriptions and line-drawings of them were presented, as well as their comparisons to allied taxa. Our study shed new light on the recognition of the genus. The pileipellis of the species in this genus should mostly be regarded as (sub)epithelium to hyphoepithelium, because the pileipellis of most studied species here is composed of short inflated cells in the inner layer (subpellis) and filamentous hyphae in outer layer (suprapellis). The basidiospores of the studied species, including the type species, H. impolitum, have a warty surface.

Veronicastrum wulingense (Plantaginaceae), a new species from Southwestern Hubei, China.

Project description:BackgroundThe genus Veronicastrum Heist. ex Fabr. are mainly distributed in East Asia, and only Veronicastrum virginicum (L.) Farw. is disjunctively distributed in eastern North America. The south area of China (extending to Taiwan Island) is the richest in Veronicastrum species. It is of medicinal importance in China as traditional herbs used to treat ascites diseases that caused by schistosomiasis. During field investigation of plant resources in Pingbaying National Forest Park, Southwestern Hubei, China, an unknown flowering population of Veronicastrum was discovered from thick humus layers adjacent to rocks under broad-leaved forests by walkways. They were collected and morphological characters assesed for further taxonomic treatment. Molecular analysis was also conducted to ascertain its phylogenetic position in the genus Veronicastrum.ResultsThis species is similar to Veronicastrum liukiuense (Ohwi) T.Yamaz. from the Ryukyu Islands, but can be distinctly differed by its axillary inflorescences (versus terminal on short leafy branches), pedicels up to 2.5 mm (versus sessile), corollas purple to purple-red (versus white tinged with pale purple) and florescence June to July (versus September to October). Also, phylogenetic studies showed the species was an independent clade in the genus Veronicastrum based on the maximum likelihood (ML) analyses using two different matrix sequences of concatenated molecular markers. The plastid genome of this new species is also reported in this study for the first time.ConclusionThe morphological and molecular evidences support the recognition of Veronicastrum wulingense as a new species.

New Species of Talaromyces (Trichocomaceae, Eurotiales) from Southwestern China.

Project description:Species of Talaromyces are cosmopolitan and ubiquitous, and some are of industrial and medicinal importance. Species of Talaromyces have been successively reported in China. During our examinations of samples collected from southwestern China, two new species belonging to Talaromyces sect. Talaromyces were further discovered based on phylogenetic analyses and morphological comparisons. Talaromyces ginkgonis sp. nov., isolated from a partially colonized fruit of Ginkgo biloba, differs from closely-related fungi in the combination of conidia ellipsoidal, smooth and 3.5-4 × 2-3 μm, no growth on CYA at 37 °C and sequence divergences; T. shilinensis sp. nov. is distinguished from its related allies in the combination of smooth conidia, colonies 10-11 mm diameter on CYA at 25 °C and sequence differences. Detailed descriptions and illustrations of the new taxa are given.
