Molecular Phylogenetic Data

Ten new species of Cortinarius are described from Costa Rican neotropical montane forests based on morphological and molecular phylogenetic data. Morphological features of the basidiomes and nuclear rDNA sequence analyses place these species in the following clades: Anomali ( Cortinarius sericeolazulinus ), Cotoneus ( Cortinarius aureopigmentatus ), Limonii ( Cortinarius aurantiobrunneus ), Lustrati ( Cortinarius comarostaphylii , Cortinarius comparioides , Cortinarius ovreboi ), Myxacium ( Cortinarius costaricensis ), and Telamonia ( Cortinarius carranzae , Cortinarius quercoarmillatus , Cortinarius savegrensis ). Species delimitations, diagnostic characters, sequence pair wise comparisons, and affinities to closely related species are included for each species. These Cortinarii occur with several species of Quercus with the exception of C. comarostaphylii, which is associated with Comarostaphylis (Ericaceae) in the páramo and in mixed forests with Quercus and Comarostaphylis.

A New Species

Exploration of the deep sea off the Pacific margin of Costa Rica has resulted in the discovery of a number of new species and reports for the region. Here, we report on the occurrence of the octocoral genus Swiftia, and describe a new species collected by the Alvin submersible off the Pacific coast of Costa Rica. The new species has been observed at around 1000 m depth, growing on authigenic carbonates near methane seeps. Swiftia sahlingi sp. nov. is characterised by having bright red colonies that are with limited branching, with slightly raised polyp-mounds, thin coenenchyme mainly composed of long warty spindles, and conspicuous plates. A molecular phylogenetic analysis supports the differences between this new taxon and the closest Swiftia species. The new species represents the first record of the genus from Costa Rica and in fact for the Eastern Tropical Pacific.

Abundance Estimates

Abstract:Tropical forest insects are vertically stratified between the canopy and understorey. Using 60 traps set at two heights above the forest floor (30 at 15 cm and 30 at 1 m) we compared abundances in capture height, persistence in traps, and sex of three co-occurring understorey butterflies (Cithaerias pireta, Dulcedo polita and Pierella helvina) in Costa Rica. We captured, marked and released 283 individual butterflies (65 C. pireta, 79 D. polita, 139 P. helvina) and showed all three species were captured more often in low traps, and P. helvina was captured only in low traps. The probability of remaining in traps for 24 h did not differ significantly for D. polita and P. helvina, but was significantly lower for C. pireta. The odds of trapping either sex did not differ significantly for P. helvina and C. pireta, but they were significantly lower for D. polita males. We experimentally demonstrate that these co-occurring species fly and feed just above the forest floor, but differ with respect to their persistence in traps and attraction to traps by sex. Our study implies that closely related species can exhibit behavioural differences that may influence population abundance estimates in multi-species studies.

During a search for populations of wild common bean, namely south of the Central Valley of Costa Rica, a new bean species, Phaseolus albicarminus, has been found on the slope of a mountainous range named Cerros Llano Bonito in the western part of Talamanca range, where it appears to be endemic. Its main morphological features are: short pseudoracemes with four small deltoid primary bracts, small early caducous deltoid bracteoles, calyx lobes reduced to two lips, white wings contrasting with carmine purple inner face of standard, and smoothly curved 3–4 seeded pods with prow-shaped beak. The differences with apparently closely related species, P. hygrophilus and P. angucianae, are: in primary bracts (orbicular versus oval acuminate), larger bracteoles (cordate versus rounded), inner face of standard (pale pink to white versus purple), lower calyx lobes (rounded versus triangular), and pod dorsal suture (straight versus sigmoid), respectively. The fact that to date only three populations of P. albicarminus are known from the same small area of Costa Rica, calls for monitoring its conservation status. This new species is tentatively assigned to the section Brevilegumeni which seems well represented in Costa Rica (with five out of six taxa).

Twenty-two non-lichenicolous species of Tremella are reported from Russia. Detailed descriptions, photographs, illustrations and a dichotomous key for the identification of taxa are provided. Two species, Tremella subalpina and T. griseola, are described as new. One new combination is proposed, and an epitype for Tremella yokohamensis is designated. Molecular phylogenetic reconstructions are presented based on nrITS and nrLSU regions in Bayesian and likelihood analyses. Phylogenetic data were strongly correlated with morphological data and were useful to delimit closely related species.

A New Species

Ophiocordyceps is the largest genus in the family Ophiocordicipitaceae, including many entomopathogenic species. In recent years, many species have been described in this genus, with a wide range of host insects. Entomopathogenic fungi include ecologically, economically and medicinally important species, but a large portion of their diversity remains to be discovered and described. In this study, a new species, Ophiocordyceps aphrophoridarum sp. nov, parasitising Aphrophoridae sp. (Hemiptera) is proposed from China, based on evidence from morphology and molecular phylogenetic analyses. This species is characterised by fibrous, pigmented stromata, cylindrical asci and filiform ascospores. Compared to its closest relative, O. tricentri, the new species has wider perithecia and longer asci. Molecular phylogenetic analyses of a multilocus dataset (consisting of SSU, ITS, LSU, TEF1, RPB1 and RPB2) confirm its placement in Ophiocordyceps. Ophiocordyceps aphrophoridarum is morphologically described and illustrated with colour photographs. Morphological comparisons with closely-related species are also presented in tabulated format.

Technical Description

A new ectomycorrhizal fungus from southwestern China, Craterellus atrobrunneolus, is proposed as supported by morphological and phylogenetic analyses. The basidiocarps are characterized by a dark brown to brownish gray coloration, convex to plano-convex pileus with an umbilicate but not perforate center, smooth to slightly folded gray to cretaceous hymenophore, absence of clamp connections in all tissues, narrow basidia with 2–6 sterigmata, and broadly ellipsoid to subglobose basidiospores. Maximum likelihood and Bayesian sequence analyses of the ITS + nrLSU DNA regions confirm the phylogenetic position of the new species. Illustrations accompany the technical description and comparisons of C. atrobrunneolus and closely related species.

The wiegmannii group of Liolaemus includes L. arambarensis, L. azarai, L. lutzae, L. occipitalis, L. multimaculatus, L. rabinoi, L. riojanus, L. salinicola, L. scapularis, L. wiegmannii, and the species described here. We used sequences of the mitochondrial cyt–b, 12S, and ND4, and the nuclear C–mos gene regions to infer the phylogeny of the majority of the species of the wiegmannii group. We describe a new species that is closely related to L. multimaculatus and L. riojanus, but can be distinguished by a different dorsal coloration, absence of suprascapular spots, and smaller size. Liolaemus cuyumhue sp. nov. lives in marked geographic isolation with respect to other closely-related species of the wiegmannii group.

Two new species of the genus Impatiens (Balsaminaceae) from Putao, Kachin State, Myanmar, are here described and illustrated. Impatiens casseabriae can be easily recognized by its narrowly elliptic to narrowly oblanceolate leaves, petioles up to 3 mm long, lower lateral united petals 25–40 mm long. Impatiens putaoensis differs from its closely related species I. xanthina in having light greenish yellow flowers, lateral sepals ovate to elliptic, lower lobe of united petals semilunar, upper lobe of united petals dolabrate, dorsal petal ovate to nearly orbicular, with a narrow inconspicuous dorsal crest. Molecular phylogenetic analyses of sequences from both nuclear ribosomal and plastidgenes confirm that the two new species are distinct from previously recorded species.

Pimpinella ibradiensis, an unusual new species found in the Toka Yayla (İbradı, Antalya) in southern Anatolia, is described and illustrated. Site conditions, synecology and conservation status of P. ibradiensis are considered. In light of the comparison with the other closely related four species, namely P. nephrophylla, P. flabellifolia, P. sintenisii and P. paucidentata, its similarity within the genus are discussed. P. ibradiensis is easly distinguished from its relatives by its white petals, presence of bracts and bracteoles, larger fruits (4–5.5 × 1–2 mm), and having serrulate basal leaves with 60–95 strongly cartilaginous teeth along margins. The geographical distribution of P. ibradiensis and closely related species are mapped and the identification key of those species is updated.
