The methods and results of a taxonomic revision of Oberonia in Thailand are presented following a historical outline. The traditional methods and techniques of morphology-based botanical revision work were used, and the revision relied on examination of dried as well as liquid-preserved specimens from 13 herbaria, supplemented with observations of live plants made during 25 field trips to five of the seven floristic regions of Thailand. The taxonomic value of selected morphological characters is surveyed, as are ecological aspects, occurrence patterns in Thailand and the overall geographic affinities of the Oberonia species represented in the Thai flora. Fourty-two species are accepted, whereas the only report of O. latipetala from Thailand is considered dubious. Full taxonomic accounts are provided for the genus and species, including a dichotomous key to the species. Whereas all morphological descriptions have been prepared from Thai material only, the synonymies are intended to be complete; O. acaulis, O. dolichostachys, O. falcata, O. longirachis, O. nitida and O. rasmussenii are proposed as new taxonomic (heterotypic) synonyms. The accepted names O. denticulata, O. hosseusii and O. lotsyana are lectotypified, and solutions are provided for long-standing taxonomic/nomenclatural problems, especially in relation to the name O. iridifolia. All accepted species are illustrated by line drawings, and references are provided to additional good illustrations in the literature.

Following a historical outline, the methods and results of a taxonomic revision of Liparis in Thailand are presented. Applying the traditional methods and techniques of morphology-based botanical revision work, the revision mainly relied on examination of dried and liquid-preserved specimens from 13 herbaria. However, the herbarium studies were supplemented with observations of live plants made during 24 field trips to five of the seven floristic regions of Thailand. The taxonomic value of selected morphological characters is assessed, and ecological aspects are surveyed together with occurrence patterns in Thailand and the overall geographic affinities of the Liparis species represented in the Thai flora. Thirty-seven species are accepted, whereas reports of L. distans and L. kwangtungensis from Thailand are treated as dubious. One new species, L. buddhawongii, is described as new, based on material from Doi Ang Khang in Chiang Mai province. Full taxonomic accounts are provided for the genus and species, including a dichotomous key to the species. Whereas the synonymies are intended to be complete, all morphological descriptions have been prepared exclusively from Thai material. The accepted names L. balansae and L. resupinata are lectotypified, whereas a neotype is designated for L. ferruginea; L. downii and L. melanoglossa are proposed as new taxonomic (heterotypic) synonyms. All accepted species are illustrated by line drawings, and references are provided to additional good illustrations in the literature.

The Status

The family Harrimaniidae (Hemichordata: Enteropneusta) is revised on the basis of morphological characters. The number of harrimaniid genera is increased to nine by the addition of Horstia n. gen., Mesoglossus n. gen., Ritteria n. gen. and Saxipendium, a genus previously assigned to the monospecific family Saxipendiidae. The number of species is increased to 34, resulting from the description of five new species from the eastern Pacific — Horstia kincaidi, Mesoglossus intermedius, M. macginitiei, Protoglossus mackiei and Ritteria ambigua. A description is supplied for a sixth harrimaniid species, Stereobalanus willeyi Ritter & Davis, 1904, which previously had the status of a nomen nudum. Four harrimaniids previously assigned to the genus Saccoglossus are transfered to the genus Mesoglossus — M. bournei, M. caraibicus, M. gurneyi and M. pygmaeus, while Saccoglossus borealis is reassigned to the genus Harrimania. Notes on habitat and zoogeography are included for the seven foregoing species and a table of diagnostic characters for existing and new species and a dichotomous key to the enteropneust families and harrimaniid genera are provided. Finally, a phylogenetic hypothesis concerning the Harrimaniidae is postulated, with discussion on the evolution of the group.

AbstractThoracocyphus Emden is a genus of broad-nosed weevils (Entiminae: Naupactini) with only two species: T. denticollis Emden and T. hatschbachi Bondar. Both taxa are endemic to Brazil and range in the states of Goiás, Minas Gerais and Paraná. Based on morphological characters of the antennae, eyes, mouth-parts, corbel plates and spermatheca, Thoracocyphus is closely related to Briarius [Fischer de Waldheim] (syn. of Lamprocyphus Marshall). The strong denticles located on the inner face of the three pairs of tibiae, and the presence of tubercles on the sides of the pronotum and humeri indicates that Thoracocyphus is more closely related to Teratopactus Heller. This contribution includes redescriptions of the genus and its species, a dichotomous key, habitus photographs and illustrations of the diagnostic characters of the external morphology, mouth-parts and genitalia.

In present research, we revised the taxonomy of Flemingia for the whole Indochinese floristic region, which consist of 24 species and one variety. China was the most diversified country with 18 species of Flemingia and one variety, followed by Myanmar (16 species), Thailand (13 species and one variety), Vietnam (12 species and one variety), Laos (12 species and one variety), and Cambodia (5 species). Flemingia weii is newly described from China, F. sootepensis and F. nana are new records for China, F. kerrii and F. mengpengensis are new records for Myanmar, and F. semialata is a new record for Vietnam and China. Based on the identity of morphological characters, we synonymized F. ferruginea var. eglandulosa, F. yunnanensis, F. kradungensis, F. tiliaceae under F. kerrii, F. macrophylla, F. kweichowensis, F. strobilifera, respectively. Furthermore, the lectotype of F. ferruginea var. eglandulosa and F. lineata var. hirtella are designated here. For each species, accepted names, literature, synonyms, type specimens, full description, iconography citation, ecology, phenology, distribution and taxonomic notes with morphologically characters have been studied in detials. In order to facilitate species identification and delimitation, a dichotomous key to the known species of Flemingia within the Indochinese floristic region was provided. Additionally, some doubtful species were also discussed.

A taxonomic revision of the Amazonian species of Ropalomera Wiedemann, 1824 (Diptera: Ropalomeridae) is presented,based on well-known and new morphological characters, especially of the male terminalia. Eight previously known spe-cies are redescribed, with illustrations: Ropalomera clavipes (Fabricius, 1805) (lectotype and paralectotypes here desig-nated), R. femorata (Fabricius, 1805), R. glabrata Prado, 1966, R. goyana Prado, 1966, R. nudipes Frey, 1959, R. tessellataPrado, 1966, R. tibialis Walker, 1852, and R. titillatrix Steyskal, 1967 (lectotype and paralectotypes here designated). Onenew species, R. albifaciata sp. nov., is described from the type-locality in Manaus, Amazonas, Brazil. The nine speciescan be identified with the dichotomous key provided. R. glabrata and R. goyana are reported for the first time for the stateof Amazonas, and the latter is also reported for the state of Pará. With this study, the number of known species in Amazonia is increased from six to nine.

Distribution Data

A worldwide taxonomic revision of the species belonging to the moss genus Chionoloma Dixon (Pottiaceae) is here presented. Our work is based on the morphological analysis of more than 2600 specimens deposited in different herbaria or collected during field trips. A total of 131 names were found and their nomenclatural types were examined, resulting in the lectotypification of 45 names. It is concluded that Chionoloma is composed of 22 species and one variety, seven of them are here newly combined (C. circinatum (Besch.) M. Alonso, M. J. Cano & J. A. Jiménez; C. cylindrotheca (Mitt.) M. Alonso, M. J. Cano & J. A. Jiménez; C. hyalinoblastum (Broth.) M. Alonso, M. J. Cano & J. A. Jiménez; C. melanostomum (Mitt.) M. Alonso, M. J. Cano & J. A. Jiménez; C. orthodontum (Müll. Hal.) M. Alonso, M. J. Cano & J. A. Jiménez; C. sarawakense (Dixon) M. Alonso, M. J. Cano & J. A. Jiménez; and C. stenocarpum (Thér) M. Alonso, M. J. Cano & J. A. Jiménez). Moreover, 42 names are newly synonymized and a total of 74 new records for various countries are reported. Keys, descriptions, illustrations, photographs, and distribution data of each species are provided.

AbstractThe eastern Mediterranean basin hosts a remarkably high plant diversity. Historical connections between currently isolated areas across the Aegean region and long-distance dispersal events have been invoked to explain current distribution patterns of species. According to most recent treatments, at least two Cymbalaria species occur in this area, Cymbalaria microcalyx and C. longipes. The former comprises several intraspecific taxa, treated at different ranks by different authors based on morphological data, evidencing the need of a taxonomic revision. Additionally, some populations of C. microcalyx show exclusive morphological characters that do not match any described taxon. Here, we aim to shed light on the systematics of eastern Mediterranean Cymbalaria and to propose a classification informed by various sources of evidence. We performed molecular phylogenetic analyses using ITS, 3’ETS, ndhF and rpl32-trnL sequences and estimated the ploidy level of some taxa performing relative genome size measures. Molecular data combined with morphology support the division of traditionally delimited C. microcalyx into C. acutiloba, C. microcalyx and C. minor, corresponding to well-delimited nrDNA lineages. Furthermore, we propose to combine C. microcalyx subsp. paradoxa at the species level. A group of specimens previously thought to belong to Cymbalaria microcalyx constitute a well-defined phylogenetic and morphological entity and are described here as a new species, Cymbalaria spetae. Cymbalaria longipes is non-monophyletic, but characterized by being glabrous and diploid, unlike other eastern species. The nrDNA data suggest at least two dispersals from the mainland to the Aegean Islands, potentially facilitated by marine regressions.

As Species

Within Astraea Klotzsch (1841: 194), Astraea lobata (Linnaeus 1753: 1005) Klotzsch (1841: 194) may be considered the most taxonomically complex species due to its wide geographical distribution and the several varieties that have been proposed for this species by Müller Argoviensis (1866, 1874). In his concept, Müller Argoviensis (1866) united under Croton lobatus Linnaeus (1753: 1005) plants with 3–5-partite leaves almost as long as the petioles, subulate stipules, the bracts not well developed and ovaries with varied indumentum. In De Candolles’s Prodromus, Müller Argoviensis (1866) recognized eight varieties, maintaining this concept in the Flora Brasiliensis (Müller Argoviensis 1874) with few modifications. Morphological characters and geographical distribution support the recognition of some of these varieties as species distinct from A. lobata. As part of an undergoing taxonomic revision of Astraea, these distinct taxa must be validly published for further studies on this genus. Therefore, in this note we propose these novelties with commentaries about morphology and geographic distribution, along with photos to illustrate them and lectotypifications when necessary.

AbstractWe analyzed the phylogenetic relationships between eight Aphidius Nees and six Lysaphidus Smith species on the basis of 12 morphological characters by parsimony analysis. The consensus tree does not support the generic status of Lysaphidus. Aphidius iranicus, sp. nov., associated with Titanosiphon bellicosum Nevsky on Artemisia absinthium L. from Iran, is described. The new parasitoid species is described and illustrated by line drawings, and its diagnostic characters are discussed. The taxonomic position of the subgenus Tremblayia Tizado and Núñez-Pérez is also considered. Tremblayia and Lysaphidus are newly classified as synonyms of Aphidius. The following new or revised combinations are proposed: Aphidius adelocarinus Smith, comb. rev., A. ramythirus Smith, comb. rev., A. rosaphidis Smith, comb. rev., A. viaticus (Sedlag), comb. nov., A. arvensis (Starý), comb. nov., and A. erysimi (Starý), comb. nov.

Lung flukes of the genus Haematoloechus Looss, 1899 are common parasites of anurans worldwide, but the taxonomy of the group has been confusing. In this taxonomic revision, 89 species of Haematoloechus (= Pneumonoeces Looss, 1902, Ostioloides Odening, 1960, Ostiolum Pratt, 1903, Skrjabinoeces Sudarikov, 1950, Neohaematoloechus Odening, 1960, Metahaematoloechus Yamaguti, 1971) are listed. Of these, 70 are considered valid, three are species inquirendae (H. legrandi Mañé–Garzón & Gil, 1959, H. latoricensis Kozák, 1968 & H. vitelloconfluentum (Rai, 1962) Saeed, Al–Barwari & Al-Harmni, 2007), one is a nomen nudum H. sudarikovi Belouss, 1962, 14 are junior synonyms and one belongs to Ostioloides. This publication also describes three new species, H. occidentalis n. sp., H. veracruzanus n. sp. and H. mexicanus n. sp., parasitizing species of Rana Linnaeus in Mexico and redescribes Haematoloechus caballeroi (Skrjabin & Antipin, 1962) Yamaguti, 1971. The phylogenetic hypotheses based on sequences of mitochondrial and ribosomal DNA of Haematoloechus spp. show that genera proposed on the basis of morphological characters are not supported. The host records for species of Haematoloechus, together with the phylogenetic hypothesis of the genus, suggest that this host-parasite association predates the ranid diversification in the Cretaceous.
