Talaromyces minioluteus belongs to the section Trachyspermi, has a worldwide distribution and has been found on various substrates, especially on various (stored) food commodities and indoor environments. This species is phenotypically and phylogenetically closely related to T. chongqingensis and T. minnesotensis. The phylogenetic and morphological analyses of 37 strains previously identified as T. chongqingensis, T. minnesotensis and T. minioluteus revealed that this clade incudes eight species: the accepted species T. chongqingensis, T. minnesotensis and T. minioluteus, the newly proposed species T. calidominioluteus, T. africanus and T. germanicus, and the new combinations T. gaditanus (basionym Penicillium gaditanum) and T. samsonii (basionym Penicillium samsonii). In this study, we give insight of the phylogenetic relationships and provide detailed descriptions of the species belonging to this clade. Macromorphological features, especially colony growth rates, texture and conidial colors on agar media, are important characters for phenotypic differentiation between species.

AbstractAmong Permian smaller foraminifers, the genus Dagmarita is one of the most studied due to its worldwide distribution. The detailed study of the Zal (NW Iran) and Abadeh (Central Iran) stratigraphic sections led to redescription of the genus Dagmarita and its taxonomic composition. In Dagmarita, a peculiar generic morphological character, represented by a secondary valvular projection, has been detected for the first time among globivalvulinid foraminifers. The phylogeny of Dagmarita, and in particular its ancestor Sengoerina, is discussed and the new species, D. ghorbanii n. sp. and D. zalensis n. sp., are introduced. Analogies and differences among all the species belonging to Dagmarita are highlighted and morphological features of the new taxa are shown in 3D reconstructions, useful for understanding differently oriented sections of the specimens in thin section.UUID: http://zoobank.org/3d8eb14c-7757-4cbd-877c-4bacd2d156da

Matk Sequence

The phylogenetic relationships within Specklinia (Pleurothallidinae; Orchidaceae) and related genera are re-evaluated using Bayesian analyses of nrITS and chloroplast matK sequence data of a wide sampling of species. Specklinia is found paraphyletic in the DNA based trees, with species alternatively assigned to Muscarella proven distinct, monophyletic and easily recognizable. Specklinia as such includes about 100 morphologically highly diverse species. Their phenotypic differences have prompted the creation of up to eleven generic names within this relatively small group. Here we show not only that these morphologically divergent species are closely related, but also that they can still be recognized by certain conserved morphological traits. The genera Acostaea, Areldia, Empusella, Cucumeria, Gerardoa, Pseudoctomeria, Sarcinula, Sylphia, Tribulago and Tridelta are found embedded within Specklinia, and therefore reduced under the synonymy of the latter. Specklinia is confirmed as sister to a clade that includes Platystele, Scaphosepalum and Teagueia. Five well-supported subgenera are proposed for Specklinia and are characterized both geographically and morphologically. The species belonging to each subgenus are listed. Incaea is synonymized with Dryadella, while Rubellia is reduced under Platystele. New combinations for several species are proposed. The criteria for the generic delimitation of Specklinia and other genera in the Pleurothallidinae are discussed.

A New Species

The genus Elaphropeza Macquart from the Oriental region is revised. In addition to the 79 known species (including seven new combinations of species previously placed within Drapetis Meigen) 51 new species are described and illustrated. The study is mainly based on freshly collected material in Singapore (544 samples, year cycle in eight stations and numerous hand captures). Smaller samples were available from Malaysia, Thailand and Cambodia. Of the 51 new species only 43 have been given a name: E. acantha sp. nov., E. asexa sp. nov., E. asiophila sp. nov., E. belumut sp. nov., E. benitotani sp. nov., E. bezzii sp. nov., E. bulohensis sp. nov., E. chekjawa sp. nov., E. combinata sp. nov., E. crassicercus sp. nov., E. darrenyeoi sp. nov., E. demeijerei sp. nov., E. equalis sp. nov., E. feminata sp. nov., E. flavicaput sp. nov., E. furca sp. nov., E. limosa sp. nov., E. luanae sp. nov., E. luteoides sp. nov., E. malayensis sp. nov., E. meieri sp. nov., E. melanderi sp. nov., E. modesta sp. nov., E. monacantha sp. nov., E. monospina sp. nov., E. murphyi sp. nov., E. neesoonensis sp. nov., E. ngi sp. nov., E. pauper sp. nov., E. pluriacantha sp. nov., E. riatanae sp. nov., E. sime sp. nov.,E. singaporensis sp. nov., E. singulata sp. nov., E. sivasothii sp. nov., E. spicata sp. nov., E. spiralis sp. nov., E. sylvicola sp. nov., E. temasek sp. nov., E. tiomanensis sp. nov., E. ubinensis sp. nov., E. yangi sp. nov., E. yeoi sp. nov. Eight species known only as females are briefly diagnosed but not named. Species (including type materials in most cases) described by C.R. Osten-Sacken, M. Bezzi, J.C.H. de Meijere, R. Senior-White, A.L. Melander and K.G.V. Smith were examined and re-described. Neotypes have been designated for E. calcarifera Bezzi, E. melanura Bezzi, E. formosae Bezzi and E. scutellaris Bezzi. Elaphropeza exul Osten-Sacken, 1882 is transferred as Crossopalpus exul (Osten-Sacken) comb. nov. Elaphropeza formosae Bezzi sensu Quate, 1960 re-described by L.W. Quate from Micronesia, is considered a new species and a new name is given: E. quatei sp. nov. All species of Elaphropeza are divided into two main species groups: E. biuncinata group and E. ephippiata group. Phylogenetic relationships within Elaphropeza are provisionally outlined. Some interesting morphological features and phenology of the species are discussed. Fourteen species have been found exclusively in mangroves. A key is given to the species of the Oriental Region (Indian subcontinent, Southeast Asia, Philippines and Taiwan, but excluding certain species of the Chinese mainland that proved to be different from the rest of the Oriental Region). A check list of the Oriental species is provided.

AbstractMicropsectra Kieffer, 1909 is described and diagnoses presented for the imaginal (♂♂), pupal and larval stages; females of the notescens-group are described. The genus contains at present 83 species of which 9 are described on females. The type material for 16 of these species has not been found. 142 species which have been listed under Micropsectra are presented in alphabethical order. This list contains: name of author, reference to description. name of original genus, present status of species, reference to the paper in which this was listed, collection in which the type material is deposited. Morphological characteristics, evolutionary trends and phylogenetic relationships of Micropsectra are discussed. The genera Rheotanytarsus, Parapsectra, Krenopsectra, Micropsectra and Paratanytarsus form a monophyletic group within the tribe Tanytarsini. The group is referred to as the Micropsectra series. Rheotanytarsus, the most plesiomorphic genus in the series, has a worldwide distribution. This supports the conclusions reached by the morphological analysis. The genera Parapsectra and Krenopsectra are only known from the Palaearctic and Nearctic Regions. The great majority of Micropsectra species are found in the Palaearctic and Nearctic Regions. A smaller number of species occur in the northern part of the Oriental Region, which has the same environmental conditions as the adjacent areas of the Palaearctic Region. Two doubtful species have been reported from India. Genus Paratanytarsus has a wider distribution but clearly has its origin on the northern hemisphere. The habitat selection in the Micropsectra series is studied and compared with the phylogeny. The species within the plesiomorphic genera Rheotanytarsus, Parapsectra and Krenopsectra are found in streams and springs. In the more apomorphic genus Micropsectra many of the species occur in these types of habitats, though there are also a comparatively high number of species occurring in lakes. Paratanytarsus, the most apomorphic genus contains species which inhabit shallow standing waters. It seems probable that the ancestor of the Micropsectra series was an inhabitant of running water. A lectotype is designated for Tanytarsus retusus Goetghebuer.

ABSTRACT Airborne actinomycete spores, important contaminants in occupational and residential environments, were studied with respect to their (i) release into the air, (ii) aerodynamic and physical size while airborne, and (iii) survival after collection onto agar with an impactor. Three actinomycete species were selected for the tests to exemplify the three main spore types: Streptomyces albusfor arthrospores, Micromonospora halophytica for aleuriospores, and Thermoactinomyces vulgaris for endospores. The results show that the incubation conditions (temperature, time, and nutrients) needed for the development of spores for their release into air are different from the conditions that are needed for colony growth only. Additional drying of M. halophytica and T. vulgaris cultures was needed before spores could be released from the culture. The aerodynamic sizes of the spores, measured with an aerodynamic particle sizer, ranged from 0.57 (T. vulgaris) to 1.28 μm (M. halophytica). The physical sizes of the spores, when measured with a microscope and an image analysis system, were found to be smaller than previously reported in the literature. The relative recovery of the spores on agar media ranged from 0.5 (T. vulgaris) to 35% (S. albus). The results indicate that the culturability of the collected airborne actinomycete spores varies widely and is affected by several variables, such as the species and the sampling flow rate. Therefore, alternatives to commonly used cultivation methods need to be developed for the enumeration of actinomycete spores.

AbstractThe balsam twig aphidMindarus abietinusKoch (Hemiptera: Aphididae) is a major pest of economic importance for the Christmas tree industry. Global warming during the 21st century could potentially increase local population densities and reinforce the pest status of this aphid in commercial fir (AbiesMiller; Pinaceae) plantations in Québec, Canada. During this study, we tested the effects of a warmer environment on colony growth rates ofM. abietinusand aphid morph composition during the second generation of its cycle, which is key to colony size growth and potential damage to Christmas trees. We monitoredM. abietinuspopulations on two host fir species and one host fir variety, in order to understand the early season dynamics of this aphid and its host tree. It was possible to distinguish the two overlapping generations of winged aphids leaving colonies, which led to observing a much higher proportion of wingless daughters, produced by the stem mother, than what had previously been reported. Colony growth rates were significantly higher in a warmer environment than in the nearby plantation, suggesting that warmer temperatures in late spring and early summer may provide the suitable conditions required forM. abietinuscolonies of greater density.

Phylogenetic Data

The paleotropical monocot Pandanaceae family comprises c. 700 species distributed into five genera: Benstonea (c. 60 spp.), Freycinetia (c. 250 spp.), Martellidendron (6 spp.), Pandanus (c. 450 spp.) and Sararanga (2 spp.). Benstonea was circumscribed to include species previously placed in Pandanus section Acrostigma (one of the four sections of Pandanus subgenus Acrostigma). New phylogenetic data show that the six species of the remaining three sections of subgenus Acrostigma (sections Epiphytica, Fusiforma and Platystigma) and a seventh species doubtfully placed in section Acrostigma (Pandanus microglottis) also belonged to Benstonea. This genus is therefore characterized by a suite of morphological characters, viz. stigmatic groove on the adaxial side of the stigma and a staminate flower reduced to 1 to 3 free stamens (sometimes joined at base). We therefore make here the necessary seven new combinations accompanied by one lectotypification in Benstonea, a genus that now reflects the view of the visionary Benjamin Stone who had already grouped these species in Pandanus subgenus Acrostigma based solely on morphology.

AbstractThe genus Pharpa is erected to include three species of Braconidae in the subfamily Agathidinae, viz. P. dubiosum (Szépligeti), P. basimacula (Cameron), and P. simulatrix (Cameron) all new combinations. Microdus albitarsis Cameron is newly synonymized with P. basimacula (Cameron). The genus Pharpa is distributed widely throughout the neotropics from southern Mexico to northern Argentina. Phylogenetic relationships with other agathidine genera are discussed, as is the possibility that the various species represent a polytypic, conspecific, mimetic complex.

The aim of the present study was to investigate the gallic acid influence on Aspergillus carbonarius growth and ochratoxin A (OTA) biosynthesis. A mixed inoculum was used in Czapek Yeast Extract Agar and growth and OTA production was observed at 100 to 500 mg/l of the phenolic compound. Slower colony growth rates and longer lag phases were observed with increasing concentration and 500 mg/l was totally inhibitory for A. carbonarius growth. OTA production decrease was observed even at the lower concentration assayed. Gallic acid could be used as a natural antimicrobial for the control of ochratoxigenic A. carbonarius.
