A New Species

Ruehmaphelenchus quercophilus n. sp., isolated from a dying oak, Quercus robur, in the State Forests, Łopuchówko District, Poland, is described and figured. It is characterised by three lateral lines, relatively stout body, excretory pore posterior to nerve ring, five caudal papillae, spicules relatively small (12-14 μm) with weakly developed condylus and rostrum, bursa absent, vulva positioned at ca 78% of body length, vulval flap absent, post-uterine branch extending for slightly over half of vulva to anus distance, and conoid tail with a bend at the distal end forming a terminal projection 10-14 μm long. The new species is very similar to four other described species, namely R. formosanus, R. juliae, R. thailandae, and R. sirisus. Detailed phylogenetic analysis based on 18S, 28S D2-D3 and ITS sequences has confirmed the status of this nematode as a new species.

A new species of Aoruroides Travassos & Kloss, 1958 (Nematoda: xyuridomorpha: Thelastomatidae) parasite of the wood-burrowing cockroach Panesthia angustipennis spadica (Shiraki, 1906) (Blattodea: Blaberidae: Panesthiinae) from Japan with comments on the validity of the genus Aoruroides

Aoruroides chubudaigaku n. sp. (Nematoda: Oxyuridomorpha: Thelastomatidae) is described from the wood-burrowing cockroach Panesthia angustipennis spadica (Shiraki, 1906) (Blattodea: Blaberidae: Panesthiinae) from Aichi prefecture, Japan. Females of A. chubudaigaku n. sp. are similar to A. costaricensis Carreno & Tuhela, 2011 by the position of the nerve ring at level of the first third of the isthmus, the body length and the comparative measurements of the oesophagus and tail. They differ by the position of the excretory pore and the vulva. The males of A. chubudaigaku n. sp. are characterized by the absence of ornamentations in the cervical cuticle and the nerve ring located at the posterior third of the corpus. In addition, the males of the new species can be differentiated by the length of the body and the comparative lengths of the oesophagus and the tail. The phylogeny of A. chubudaigaku n. sp. is inferred by the D2-D3 domains of the LSU rDNA and the validity of the genus Aoruroides Travassos & Kloss, 1958 is discussed on the basis of both molecular and morphological data. This constitutes the first species of the genus Aoruroides described from the Japanese archipelago.

Summary Bursaphelenchus parayongensis n. sp. was isolated from packaging wood of a consignment from China exported to Germany. The new species is characterised by the lateral field with three lines, 9-13 μm long stylet with small basal swellings, and the excretory pore located near the posterior part of metacorpus. The male spicules are mitten-shaped, the lamina smoothly tapers towards the distal tip. The condylus is broadly rounded, with a small dorsally bent hook, rostrum triangular with sharply pointed tip, and without cucullus. One precloacal papilla, one adcloacal pair and two postcloacal pairs of male papillae present, with the posteriormost pair forming ‘gland papillae’. Bursal flap long, spade-like with posterior margin truncate or irregular. Females have a small vulval flap of 2-3 μm long, and a post-vulval uterine sac extending for 55-77% of the vulva to anus distance. Tail cylindrical, mostly (about 70%) with a robust mucron, very short to less than 3 μm, but occasionally tail terminus bluntly rounded, without mucron. It is similar to species in subgroup 3 of the eggersi group including B. carpini, B. clavicauda, B. cryphali and B. yongensis, but morphologically different. Detailed phylogenetic analysis based on partial 18S, ITS and D2-D3 region of 28S sequences has confirmed the status of this nematode as a new species.

It is characterised by a relatively slim body (a = 42 and 43 for males and females, respectively), three lines in the lateral field, male spicules relatively small (12-18 μm) with high and dorsally bent condylus and weakly developed rostrum, bursal flap absent, short tail possessing a long terminal spike ending in a bluntly rounded tip and 8.7-13.3 μm long, vulva positioned at ca 83% of body length, vulval flap absent, vulval lips slightly protruding, post-vulval uterine branch extending for less than half of vulva to anus distance, and female tail conoid, ca 3-4 anal body diam. long, with 13.7-18.5 μm terminal projection. The new species can be separated from all other species of the genus by the male tail possessing a long terminal spike and the more anterior excretory pore. Detailed phylogenetic analysis based on 28S D2-D3 region sequences confirmed the status of this nematode as a new species.

Xylaria fusispora, an undescribed species of Xylaria (Xylariales, Xylariaceae), is described and illustrated as a new species based on collections from Guizhou Province, China. Both morphology and phylogenetic analysis of nrDNA ITS sequences support the establishment of this new species. The fungus is characterized by its fusoid-equilateral ascospores and an ascus apical ring not bluing in Melzer’s reagent. The differences between the new species and the related fungi are discussed.

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.

Viola huizhouensis (Violaceae), a new species from Xiangtoushan National Nature Reserve of Guangdong Province in China, is described and illustrated. The new species is most similar to V. guangzhouensis, but it can be easily distinguished by its much stouter rhizome, lack of aerial stem, dense pubescence of the basal pedicel and the whole plant. Our phylogenetic analysis, based on ITS sequences, confirms that the new species belongs to V. sect. Diffusae.

A new species of the genus Caecilia (Caeciliidae) from the western foothills of the Serranía de los Yariguíes in Colombia is described. Caecilia pulchraserranasp. nov. is similar to C. degenerata and C. corpulenta but differs from these species in having fewer primary annular grooves and a shorter body length. With this new species, the currently recognized species in the genus are increased to 35. Mitochondrial DNA sequences, including newly sequenced terminals representing two additional, previously unanalyzed species, corroborate the phylogenetic position of the new species within Caecilia and the monophyly of the genus. This analysis also included newly sequenced terminals of Epicrionops aff. parkeri (Rhinatrematidae) and trans-Andean Microcaecilia nicefori (Siphonopidae). Evidence was found for the non-monophyly of the family Siphonopidae and the siphonopid genera Microcaecilia and Siphonops. The implications of these results for caecilian systematics are discussed and the status of the trans-Andean populations of Caecilia degenerata is commented upon.
