AbstractTwo new species of Xanthoria are described and illustrated, and comments about their differences from related taxa are provided. These are: X. ascendens from bark and shrub remains in sea-shore sand dunes and hillsides in Argentina, Chile and Peru, and X. ucrainica, from bark, stones, and some man-made substrata in the Ukraine, Sweden, United Kingdom, Germany, Austria and Asian Russia.

This article is devoted to a review of specimens identified as belonging to the genus Maraenobiotus Mrázek, 1893 reported for Bulgaria from the Rhodope and Rila Mountains under the name of Maraenobiotus vejdovskyi truncatus Gurney, 1932. Closer examination of the armature of the caudal rami and other morphological characteristics revealed significant differences between the specimens from these disjunctive populations and M. truncatus that had been originally described by Gurney (1932) from the United Kingdom. Based on these differences, the population from the Western Rhodope Mountains is described here as a new species, M. rhodopensis n. sp., and the population from the Rila Mountains is described here as M. rilaensis n. sp.

Hoplia (Hoplia) dubia (Rossi, 1792) (Coleoptera: Scarabaeidae: Melolonthinae: Hopliini) is a species that is endemic of Italy, recorded for scattered localities along the coasts of the peninsula and of Sicily. Following the study of a rather large amount of specimens from the entire known range, Hoplia dubia is herein split into three allopatric species. The true Hoplia dubia is redescribed and a neotype is designated. Two new species, Hoplia (Hoplia) meridiana and Hoplia (Hoplia) messapia, are described and the Hoplia dubia species group is defined. For each species, a full description is given and diagnostic characters are summarized and compared in a table. The three species belonging to the group may be recognized mainly by morphological and chromatic differences in scales, scales density, and by setal pattern, which are all illustrated. Remarks on ecology, ethology, and phenology of adults of the species are also reported. All three species treated in this paper are restricted to coastal sand dunes. The significant loss of this habitat due to anthropogenic pressure raises concern about the conservation status of these species.

Two new species of Schizocosa are described and illustrated, namely, S. heasmani from meadow habitats in eastern Ontario and S. aulonia from the beaches and sand dunes of northeastern Illinois. These species closely resemble, respectively, S. avida (Walckenaer) and S. retrorsa (Banks), which are also illustrated.

The morphological, histochemical, and molecular properties of two new species of arbuscular mycorrhizal fungi (AMF; Glomeromycota) have been characterized. The first species is distinguished by spores that are orange to brownish orange, small, and formed only in clusters and mainly by having two laminate layers in a three-layered spore wall, with layer three staining dark in Melzer’s reagent. Despite the morphological similarity to some Septoglomus spp., phylogenetic analyses of sequences of the SSU–ITS–LSU nrDNA region and the RPB1 gene accommodated the fungus in the genus Dominikia, hence it was named Dominika emiratia. Intact spores of the second species, named Rhizoglomus dunense, closely resemble colourless isolates of R. clarum, but their spore wall layer three never becomes coloured with age, as does that in most R. clarum spores, and most importantly, the two fungi are separated by a large molecular distance. Dominikia emiratia was originally extracted from the rhizosphere of three plant species cultivated in two fields in a sandy desert in the Emirate of Abu Dhabi of the United Arab Emirates. Rhizoglomus dunense was found in a trap culture inoculated with the rhizosphere soil and root fragments of Ammophila arenaria, which had colonized sand dunes of the Mediterranean Sea, located near Thessalonica, Greece.

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

Abstract—Two new diploid species, Aira minoricensis and Aira hercynica, are described and illustrated, along with chromosome counts, risk assessment, distribution and habitat, phenology, and comparisons with morphologically similar species. A comparative table and a key for the species of Aira for the Iberian Peninsula and the Balearic Islands are provided to assist in the identification of these overlooked species, and their relationships to other taxa are discussed.

Abstract Bed-by-bed sampling of twelve Barremian sections in southeastern France from pelagic basin (Vocontian Basin) to neritic platforms (Arc of Castellane, Arc of Nice and Provencal Domain) has enabled the collection of isochronous samples of the ammonite genus Gassendiceras. Three poorly known species of the Toxancyloceras vandenheckei Zone (Upper Barremian) are revised: G. alpinum, G. multicostatum and G. hoheneggeri; two new species are described (G. rebouleti nov. sp. and G. bosellii nov. sp.). The intraspecific variability of particular species was recognised. This variability is between slender peramorphic and robust paedomorphic extreme morphologies, with the presence of all intermediates.

This paper continues the publication of new data obtained during field studies in remote and poorly studied regions of Laos in 2015–2018. It provides descriptions of two new species (Bulbophyllum brachyscapum Aver. and Sunipia saccata Aver.), emended descriptions of two previously published but insufficiently known species (Cleisostoma verrucosum Aver., Oberonia vesiculifera Aver.) and reports of eight species newly recorded in the flora of Laos (Biermannia calcarata Aver., Bulbophyllum farreri (W. W. Sm.) Seidenf., Didymoplexiella trichechus (J. J. Sm.) Garay, Eria eriopsidobulbon C. S. P. Parish et Rchb. fil., Habenaria ciliolaris Kraenzl., Liparis caudata Aver. et K. S. Nguyen, Odontochilus umbrosus (Aver.) Ormerod, and Porpax ustulata (C. S. P. Parish et Rchb. fil.) Rolfe). Appropriate citations of regional literature, colour illustrations, data on types and distribution, descriptions, etymology, as well as notes on taxonomy and related species are provided for the studied species.
