Chelystachya, a new genus of the subtribe Polystachyinae (Orchidaceae)A new genus of Orchidaceae (Polystachyinae),ChelystachyaMytnik & Szlach. is described and illustrated basing on results of molecular and morphological studies. It is related toPolystachyaHook. but is distinct in having large, single-noded, spherical, succulent pseudobulbs flattened on the substratum, pendent and densely pubescent inflorescence, lowermost lip, and lip veins directed to the lip base. Results of phylogenetic analyses based on plastid markers validate the reason for a new genus. Keys for determination of all genera of the subtribe Polystachyinae and both species ofChelystachyaare included. Two new combinations are made. A comprehensive description and full synonymy, as well as detailed ecological, phenological and distribution data and a list of 125 examined specimens are provided for each taxon treated. BecausePolystachya affinisLindl. is considered a holotype ofPolystachyaHook. sect.AffinesKraenzl., this name is automatically a synonym of the newly introduced generic nameChelystachya. Other species of the former sectionAffinesare classified within the sectionHumiles.

A new genus of Orchidaceae (Polystachyinae), <em>Isochilostachya</em>, is described. It is morphologically similar to <em>Polystachya </em>Hook. but is distinct by the narrower, grass-like leaves arranged in the upper part of the stem, long and acuminate floral bracts and sepals, and long clavate or capitate hairs densely arranged on the lip. A comprehensive description of the new genus is provided. A list of examined specimens and information about distribution, habitat, and altitude for each species are presented. A position of the members of the new genus in the cladogram recently obtained from molecular analyses of Polystachyinae is briefly discussed. A taxonomic key to Polystachyinae is included. Eleven new combinations on species level are validated. Eight lectotypes are designated. Most of the species of <em>Isochilostachya</em> are endemic to particular mountains of the Eastern Arc (Eastern Afromontane hotspot) in north-east Tanzania therefore a brief discussion about their restricted distribution is provided.

We describe a new genus, Manitischeria Diškus & Stonis, gen. nov., and five new species: Manitischeria selindica Stonis & Diškus, sp. nov., M. namibiensis Stonis & Diškus, sp. nov. from Africa, and M. brachiata Diškus & Stonis, sp. nov., M. symbolica Diškus & Stonis, sp. nov., and M. baryshnikovae Diškus & Stonis, sp. nov. from South East Asia. We discuss the diagnostics of Manitischeria gen. nov. composed of these new species and others transferred from Tischeria Zeller. Species are mostly trophically associated with Malvaceae, but also Rhamnaceae and Betulaceae. We list 18 currently known species of Manitischeria gen. nov., including M. ptarmica (Meyrick), the type species, and provide 13 new combinations and the first documentation of genitalia of some, previously little-known species. New species are illustrated with photographs or drawings of the adults, genitalia, and the leaf mines when available. We briefly discuss the use of herbarium specimens to discover lepidopteran leaf mines, host plant, and distribution data.

This paper provides new combinations for two species endemic to the Seychelles, Canthium carinatum and C. sechellarum, which are transferred to Peponidium (tribe Vanguerieae, Ixoroideae, Rubiaceae), as supported by recent molecular phylogenetic analyses. Several new combinations in Vanguerieae from Madagascar are also proposed, based on morphological studies. Canthium bakerianum and C. homolleanum are transferred to Peponidium, whereas C. andringitrense, C. mandrarense, and Peponidium montana are transferred to Pyrostria. The names Pyrostria angustifolia, P. media, and P. major, previously invalid, are here validly published.

Rubroboletus is erected as a new genus to accommodate Boletus sinicus and its allies based on morphological and molecular evidence. Morphologically, Rubroboletus differs from the remaining genera in Boletaceae by the combination of a reddish pileal surface, an orange-red to blood red surface of the hymenophore, yellow tubes, pink to red reticula or spots on the yellow background of the stipe, a bluish color-change when injured, a non-amyloid context, smooth spores which are olive-brown in deposit, and an interwoven trichodermal pileipellis. Our phylogenetic analyses based on five gene markers (ITS, nrLSU, tef1-α, rpb1 and rpb2) recognized eight species in the genus, including one new species and seven new combinations. A key to the eight species is provided.

Xylodon (Hymenochaetales, Basidiomycota) is the largest segregate genus of Hyphodontia s.l. Based on molecular and morphological data, 77 species are accepted in Xylodon to date. Phylogenetic analyses of ITS and 28S sequences, including 38 new ITS and 20 28S sequences of Xylodon species, revealed four species new to science. The new taxa X.exilis, X.filicinus, X.follis and X.pseudolanatus from Taiwan, Nepal, Réunion, Belize, and USA are described and illustrated. In addition, species concepts for Odontiavesiculosa from New Zealand and Xylodonlanatus from U.S.A. are revised and the new name X.vesiculosus is proposed. Phylogenetic analyses of the ITS region placed X.spathulatus, X.bubalinus and X.chinensis in a strongly supported clade and demonstrated that they are conspecific. Palifer and Odontiopsis are synonymised under Xylodon based on morphological and sequence data. The following new combinations are proposed: X.erikssonii, X.gamundiae, X.hjortstamii, X.hyphodontinus, X.septocystidiatus and X.verecundus. Line drawings of X.cystidiatus, X.hyphodontinus, X.lanatus and X.vesiculosus, as well as photographs of X.raduloides basidiomata, are provided. A key to X.lanatus and similar species is presented.

Taxonomic re-examination of the Gammiella ceylonensis complex is done in the light of Sematophyllaceae-Pylaisiadelphaceae circumscription based on morphological and molecular (cpDNAs: rbcL, rps4, and trnL-F) phylogenetic analyses. Three new genera are proposed to accommodate the newly recognized clades. The first is Clastobryellina that is raised from a section level under Clastobryella to include four species—two are existing species with new combinations proposed here (C. ceylonensis, C. merrillii), and two are new species described here (C. lutea, C. orientalis). Clastobryum sect. Clastobryellina is lectotypified by Clastobryum merrillii. The second is Bonnosukea, a new genus described to accommodate only B. serrulata, which is formerly included in Clastobryum, but is shown to be sister to the genus. The last is Microgammiella, a new monotypic genus that is sister to Aptychella, with a newly described species M. flagelliformis. Three species of Clastobryellina, except for a northern Thailand endemic C. lutea, show wide and disjunct distribution in East Asia.

New Synonyms

A new classification of the subtribe Lychnophorinae is proposed based on the results of phylogenetic analyses. The subtribes Centratherinae and Sipolisiinae are synonyms of Lychnophorinae and three genera (Albertinia, Blanchetia, Gorceixia) are transferred to the subtribe. As now circumscribed, Lychnophorinae comprises 19 genera and 117 species distributed mostly in the Cerrado domain of the Brazilian Central Plateau. Oiospermum is synonymized under Centratherum, and Irwinia under Blanchetia. Because Lychnophora as currently circumscribed is paraphyletic, the genus is dismantled into three monophyletic genera: Lychnophora s.s., Lychnocephalus and a new genus described herein, Lychnophorella. Seven new species are described (Chronopappus lanatus, Lychnophora grisea, L. haplopappa, Lychnophorella jacobinensis, Piptolepis riparia, Prestelia espeletoidea and Proteopsis hermogenesii), 16 new combinations are proposed (Eremanthus reticulatus, E. syncephalus, Lychnocephalus humillimus, L. mellobarretoi, L. sellowii, Lychnophora hatschbachii, Lychnophorella blanchetii, L. bishopii, L. leucodendron, L. morii, L. regis, L. santosii, L. sericea, L. triflora, Piptolepis pabstii, Prestelia purpurascens) as well as eight new synonyms. We also propose a neotype for Ampherephis pulchella, an epitype for Crantzia ovata and lectotypes for 31 names including six second-step lectotypifications (Albertinia brasiliensis, A. polycephala, Ampherephis intermedia, Centratherum fruticosum, Eremanthus leucodendron, E. purpurascens, Gorceixia decurrens, Lychnophora albertinioides, L. brunioides, L. microphylla, L. pohlii, L. reticulata, L. rosmarinus var. affinis, L. rosmarinus var. normalis, L. sellowii, Piptolepis gardneri, Proteopsis sellowii, Symblomeria baldwiniana, Vanillosmopsis albertinioides, V. glomerata, V. pohlii, V. syncephala, Vernonia burchelliana, V. ericoides, V. imbricata, V. involucrata, V. leptospermoides, V. martiana, V. platycephala, V. pseudomyrtus and V. trichocarpha).

The new genus Striatovertex is described to accomodate a distinct group of eucoiline wasps (Hymenoptera: Cynipoidea: Figitidae) currently included in the nominate genus Eucoila Westwood, but known among specialists to not belong there for decades. They are characteristically large wasps with reduced wing pubescence, parasitizing dung-breeding Diptera, and are common in North and South America, but also present in Australia and Hawaii. Their diagnostic characters place them in what is currently Ganaspini rather than very close to Eucoila in Eucoilini, and this has been confirmed by earlier phylogenetic analyses. Diagnostic and other distinctive characters are reviewed, and thirteen new combinations are made for species belonging to this group.

Recent traditional and molecular systematic studies of the violet family, Violaceae, have confirmed extensive polyphyly of the genus Hybanthus and substantial polyphyly in Rinorea as well. Phylogenetic analyses have proposed up to nine distinct hybanthoid clades. Broad studies of representative taxa within each clade have revealed coherent suites of macromorphological traits in foliage, flowers, fruits and seeds that easily discriminate the nine hybanthoid lineages from each other and from currently recognized genera in the family. Base chromosome numbers and biogeography also provide additional support for recognition of the hybanthoid clades as distinct segregate genera. Some hybanthoid clades have available older generic names, but one of the two Old World lineages, namely the Hybanthus enneaspermus group, is presently nameless. This clade, distinctive in its ellipsoid, pale yellow, often foveolate seeds, is the most diverse in the Paleotropics, with approximately 25 species distributed across Africa, Madagascar, southern Asia, northern Australia and the southwestern Pacific. The group is segregated here as Afrohybanthus gen. nov., with new combinations provided for existing names, all of which have thus far proven morphologically distinct and worthy of recognition at the rank of species. Imminent future studies will describe additional taxa in the new genus.
