Icelandic Waters

Based on material collected during the BIOICE project, the taxonomy and distribution of Terebellides (Polychaeta; Trichobranchidae) in Icelandic waters is presented. Terebellides stroemii Sars, 1853 and Terebellides gracilis Malm, 1874 (as Terebellides williamsae Jirkov, 1989) were previously reported from the area. Terebellides atlantis Williams, 1984 is reported for the first time after the original description and redescribed. Terebellides bigeniculatus sp. nov. is diagnosed by the presence of two thoracic chaetigers with geniculate chaetae. Terebellides williamsae Jirkov, 1989 is proposed as a junior synonym of T. gracilis, whose holotype is redescribed herein. Several body characters with high taxonomic value in Terebellides are reviewed under the SEM; additions to the diagnosis and new potential characters for a future taxonomic revision and phylogenetic study of the genus are also suggested. The geographical and bathymetric distribution of each species in relation to the GIF Ridge is discussed, and a key to Terebellides species from North East Atlantic waters is provided.

The genus Metalibitia Roewer, 1912, is revised for the first time, and a cladistic analysis revealed that it is a monophyletic clade. This cosmetid harvestmen genus is restricted to open forests and adjacent vegetational formations in South America (humid Forest, being found mostly in the region of cerrado/chaco/pampas). An identification key for all known species is presented and a new species is described, Metalibitia abuna sp. nov. (type locality: Abunã, Porto Velho, Rondônia, Brazil). Two species, Paralibitia maculata Roewer, 1914 and Labrosa arenosa Mello-Leitão, 1939, are here synonymized under Metalibitia argentina (Sørensen, 1884).

A New Species

Spathacanthus is a Mesoamerican genus that occurs in tropical and temperate regions from southern Mexico to Costa Rica; its taxonomy has not been updated for two decades. In view of the fact that a new species has been discovered and that the interspecific affinities in this genus have not been addressed to date, the present study aims to revise the genus Spathacanthus. Specimens of plants of this genus collected from across the distribution range and deposited in herbaria and digital databases were reviewed. In parallel, a cladistic analysis was carried out, based on morphological characters in order to examine relationships between species. Four species of Spathacanthus were recognised: one endemic to Costa Rica, another micro-endemic to Veracruz in Mexico, one more restricted to the forests of Mexico and Guatemala and the last one more widely distributed. Reflecting the previously limited knowledge of the group, many of the specimens that we studied had been misidentified. A key to differentiate these species is provided, supplemented with photographs, drawings and other illustrations, morphological descriptions, synonymy and ecological data. Results, presented here, extend the distribution range of some taxa and a distribution map is presented. The cladistic analysis recovered the genus as monophyletic, showing that S. hoffmannii and S. hahnianus are sister taxa and S. magdalenae was found to be more closely related to S. parviflorus. These plants are vulnerable to degradation and habitat loss.

The Brazilian land planarians Cratera crioula, C. joia, Geoplana hina, and G. taxiarcha (Platyhelminthes, Tricladida, Geoplanidae) are revised taxonomically from type material and additional specimens. Geoplana hina sensu Carbayo et al. (2013) was found to be an undescribed species and therefore is described and named as Cratera picuia sp. n. A new species of the genus is also described and named as Cratera arucuia sp. n. G. hina and G. taxiarcha are transferred to Cratera. The most remarkable morphological feature of Cratera—a dilated terminal portion of the ejaculatory duct—is either absent, inconspicuous, or variable in C. hina, C. joia, C. picuia sp. n., and C. arucuia sp. n. Based on the monophyletic status of Cratera inferred elsewhere, an emendation of the genus is here proposed to encompass the morphological variation observed in the genus.

A key to Piestus species is modified to include the new species. New records are provided for Piestus angularis Fauvel, Piestus bicornis (Olivier), Piestus fronticornis (Dalman), Piestus lacordairei Laporte, Piestus longipennis (Fauvel), Piestus mexicanus Laporte, Piestus minutus Erichson, Piestus pennicornis Fauvel, Piestus spinosus (Fabricius), Piestus sulcatus Gravenhorst, Piestus surrufus Caron et al. and Piestus validus Sharp. Cladistic analysis is made to know the relationship of the P. chullachaqui sp. nov. within Piestus.

The orchid genus Phloeophila is distributed from southern Mexico to Brazil and Bolivia, as well as Cuba. A taxonomic revision including the three Phloeophila species present in Ecuador is presented. Morphological characteristics, an identification key, maps of known localities and illustrations of the species are also included. In Ecuador, species of Phloeophila are only known from the Amazonian rainforests, growing from 890 to 1600 meters of altitude. Phloeophila condorana is described as a new species based on specimens collected in the Ecuadorian province of Zamora-Chinchipe and compared to Phloeophila nummularia. Phloeophila nummularia is reported for the first time in Peru. A lectotype for Pleurothallis echinantha is selected.

A New Species

Russula subsection Amoeninae is morphologically defined by a dry velvety pileus surface, a complete absence of cystidia with heteromorphous contents in all tissues, and spores without amyloid suprahilar spot. Thirty-four species within subsection Amoeninae have been published worldwide. Although most Russula species in South Korea have been assigned European or North American names, recent molecular studies have shown that Russula species from different continents are not conspecific. Therefore, the present study aims to: 1) define which species of Russula subsection Amoeninae occur on each continent using molecular phylogenetic analyses; 2) revise the taxonomy of Korean Amoeninae. The phylogenetic analyses using the internal transcribed spacer (ITS) and multilocus sequences showed that subsection Amoeninae is monophyletic within subgenus Heterophyllidiae section Heterophyllae. A total of 21 Russula subsection Amoeninae species were confirmed from Asia, Australia, Europe, North America, and Central America, and species from different continents formed separate clades. Three species were recognized from South Korea and were clearly separated from the European and North American species. These species are R. bella, also reported from Japan, a new species described herein, Russula orientipurpurea, and a new species undescribed due to insufficient material.

A New Species

We describe a new species of drongo in the Square-tailed Drongo (Dicrurus ludwigii) complex using a combination of biometric and genetic data. The new species differs from previously described taxa in the Square-tailed Drongo complex by possessing a significantly heavier bill and via substantial genetic divergence (6.7%) from its sister-species D. sharpei. The new species is distributed across the gallery forests of coastal Guinea, extending to the Niger and Benue Rivers of Nigeria. We suspect that this taxon was overlooked by previous avian systematists because they either lacked comparative material from western Africa or because the key diagnostic morphological character (bill characteristics) was not measured. We provide an updated taxonomy of the Square-tailed Drongo species complex.
