The hoverfly genus Eumerus Meigen, 1822 (Eristalinae: Merodontini) comprises 250+ described species, of which 36 are reported from the Iberian Peninsula. The high species diversity linked to the low degree of morphological differentiation between some species, which is even lower in females, leads to a high taxonomic complexity in this genus. The aim of this work is to confirm the morphological and molecular validity of an undescribed species of Eumerus, which is widespread in the Iberian Peninsula. The new species is described and compared with similar species. The genitalia of the new species are similar to those of Eumerus clavatus Becker, 1923 and Eumerus uncipes Rondani, 1850, but also share some features with Eumerus nudus Loew, 1848. The COI-5’ barcode is provided for the new taxon and analysed together with those of other named Eumerus sequences/species publicly available online. In the light of the morphology and barcoding data, the systematic position of the new species is discussed.
Based on morphological and molecular evidence, two new species of Silene are recognized and described here, S. penduliflora F.Jafari, Keshavarzi & Doostm. sp. nov. and S. thyrsiantha F.Jafari, Mirtadz. & Keshavarzi sp. nov. The newly discovered species are distributed in the central and southeastern parts of Iran, growing in rocky habitats. Relationships among these species and their close relatives are demonstrated using nrDNA ITS and cpDNA rps16 phylogenies. Silene ghahremaninejadii, S. parrowiana, and S. shahrudensis form a clade with these new species. A key to S. penduliflora and S. thyrsiantha and their close relatives is provided.
Dicranodontium didymodon, a species described from the Himalaya was recently reported from Spain. It has been distinguished from D. denudatum by a smooth subula. A reexamination of the type of this species revealed no additional characters which would support the recognition of a separate species. Therefore D. didymodon is synonymised with D. denudatum. The specimen from Spain is referred to D. denudatum var. glabrum, which differs from D. didymodon by larger stature and lack of brood leaves.
Fontinalis antipyretica var. mollis is recorded for Spain, which differs by orbicular, not keeled leaves. The presence in the same tufts together with var. antiypretica reveals that it is a somatic mutant of the latter. A form of Pellia epiphylla was observed which has wide thallus margins of unistratose cells resembling those of Aneura maxima. A Campylopus was collected resembling C. flexuosus but with ventral stereids in transverse section of the costa. It is described as C. flexuosus var. anomalus. An (unsuccessful) attempt has been made to find the locality in which P. Allorge found Campylopus setifolius for the only time in the Iberian Peninsula. The bryophilous fungus Octosporella jungermanniarum is reported as new to Spain. Dicranodontium didymodon, known before from the Himalaya and western China, is reported as new to Europe.
This article compares two similar yet never compared cases of intra-European othering: Spain and the South Slavic region. Their common denominator is what I call the Periphery Problem: a hierarchical cultural difference between Europe's symbolic centre (Western Europe) and its exotic peripheries. Using paradigmatic examples intertextually linked to Prosper Mérimée, this article focuses both on the centre (exemplified by Mérimée), and the peripheries' recent responses to Mérimée through meta-images (your image of others' image of you). The structural commonalities in characterization and the entanglements of internal and external images show that national characterization in Europe is profoundly a transnational phenomenon.
Recent studies have shown that the speciose Holarctic genera of Leiobunum C.L. Koch, 1839 and Nelima Roewer, 1910 are polyphyletic taxa, and therefore, the traditional diagnostic characters for these European genera of Leiobuninae Banks, 1893 (respectively, the presence or absence of tubercle rows on leg coxae) are unsuitable. We present the description of Leiolima iberica gen. et sp. nov., a new endemic harvestman from the north-western part of the Iberian Peninsula. The newly established genus shows intermediate characters between Leiobunum and Nelima. In addition, the new genus is characterized by shorter legs compared to Leiobunum and the presence of trichomes on all leg femora and pedipalpal patellae, a structure that is absent in all other western Palearctic genera of the subfamily Leiobuninae.
Two new species of cheilostomate bryozoans are described from material preserved in museums: Cradoscrupocellaria severoi sp. nov., from Iberian Mediterranean waters, and Setosella margaritae sp. nov., from shallow waters along the Atlantic coast of Europe. Moreover, the Mediterranean species Setosella cyclopensis Rosso, Di Martino & Gerovasileiou, 2020 is reported in Iberian waters for the first time.
