We conducted a phylogenetic study of neotropical subfamily Podostemoideae with a focus on Rhyncholacis and the monotypic Macarenia using molecular data (plastid: rbcL, trnL intron; nuclear: ITS). Our results placed the five included species of Rhyncholacis, one of which is newly described herein, in a moderately well supported (73 BP) clade with M. clavigera. These results support the transfer of M. clavigera to Rhyncholacis (R. clavigera); the nomenclatural changes are made. In addition, a new species of Rhyncholacis (R. paulana C.T. Philbrick & C.P. Bove) is illustrated and described. Rhyncholacis paulana is distinguished from all other species in the genus by its simple pinnately lobed leaf, which is fleshy and undulate. All other species of Rhyncholacis have leaves that are pinnately lobed, the lobes of which are repeatedly divided, or pinnately compound and characterized by finely dissected pinnate segments.

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.

A New Species

No species of Colletotrichum have been reported associated with Vaccinium dunalianum var. urophyllum, which is a significant medicinal plant in China. In this study, several endophytic strains were isolated from this host. Morphology and analysis of DNA sequences of nuc rDNA ITS1-5.8S-ITS2 (ITS barcode) and seven other gene regions (GAPDH, CAL, ACT, CHS-1, HIS, GS, TUB2) revealed a new species, Colletotrichum yulongense and a previously described species, C. rhombiforme. Both Colletotrichum species are described. The diversity and broad distribution of the host, suggest the likelihood of other endophytic Colletotrichum species in V. dunalianum var. urophyllum and this requires further investigation. The pathogenicity of the Colletotrichum species isolated from V. dunalianum var. urophyllum also needs testing.

A new species, Phanerotoma carobivora van Achterberg & Thackeray, sp. nov. is described from South Africa. It is a common endoparasitoid of the carob moth (Ectomyelois ceratoniae Zeller (Pyralidae) on pecan (Carya illinoinensis (Wangenh.) K. Koch) and citrus fruits in South Africa. Mean percentage of parasitism varied 2-30% between host plants and sampled localities.

Abstract— During a taxonomic and phylogenetic study of Xylopia from the Amazon River basin, South America, we examined collections from the Brazilian states of Amazonas, Mato Grosso, Pará, Rondônia, and Tocantins that resembled Xylopia nitida by some characteristics of the leaves, but differed consistently from the latter in a number of floral and fruit characters. On the basis of these specimens we describe here a new species, Xylopia maasiana. The new species is a small to medium-sized tree encountered mostly in riparian habitats across the southern Brazilian Amazon and in some transition areas between the Amazon forest and cerrado biomes in Central Brazil. In addition to the detailed description, we include a preliminary assessment of conservation status, taxonomic comments, illustrations, a distribution map of the new species, and comparison with X. nitida.

Lepiotaceous Fungi

An interesting species of lepiotaceous fungi, Leucoagaricus callainitinctus sp. nov., is described from Kerala State, India based on morphology and molecular phylogeny. This species is distinguished by basidiocarps that turn dark turquoise on bruising/handling or reacting with NH4OH. A phylogenetic study was conducted based on Maximum likelihood analysis of nrITS sequences. In the phylogram, the new species nested as a distinct lineage in a group, which consisted predominantly of members of section Piloselli of the genus Leucoagaricus. A comprehensive description, photographs of the basidiocarps and the microscopic structures, comparisons with phenetically similar and phylogenetically related species and a phylogram showing the placement of the new species are provided.

A New Species

Thygater Holmberg 1884, a Neotropical bee genus distributed from Argentina to Mexico, was last revised almost 50 years ago. Considering the species recognized then, and a few others described subsequently, 30 species are currently included in the genus. The Brazilian state of Minas Gerais is a large, environmentally heterogeneous territory, including areas in the phytogeographic domains of the Atlantic Tropical Rain Forest, the semiarid Caatinga and the highly seasonal Cerrado. The state insect fauna has been poorly sampled and studied. As part of a taxonomic and phylogenetic study of the genus, a synopsis of Thygater occurring in the state of Minas Gerais was produced, including the description of a new species (Thygater danunciae Freitas & Silveira, sp. n.), the recognition of two new synonymies, and an identification key for all 15 species of Thygater recorded for Brazil.

Sterlet Acipenser Ruthenus

Abstract A new species, Skrjabinopsolus nudidorsalis sp. nov. is described from the sterlet Acipenser ruthenus, caught in the River Volga basin (Russia). This species differs from previously described congeners by the absence of vitelline follicles on the dorsal side of the body. The complete 18S rRNA and partial 28S rRNA gene sequences obtained for S. nudidorsalis are the first molecular data for the family Deropristidae. The results of phylogenetic analysis indicate that Deropristidae is sister to the Monorchiidae + Lissorchiidae group. The results of the phylogenetic study contradict the current taxonomic hypothesis that Deropristidae belongs to the superfamily Lepocreadioidea and allow inclusion of this family in Monorchioidea. The morphological similarity of deropristids to other monorchioids is recognizable from the presence of a bipartite internal seminal vesicle, spinous cirrus and a voluminous, armed metraterm.
