Castroviejoa Galbany, L. S�ez & Bened� has been recently described as a new genus of Gnaphalieae, and comprises the two Mediterranean species Castroviejoa frigida (Labill.) Galbany, L. S�ez & Bened� and C. montelinasana (Schmid) Galbany, L. S�ez & Bened�, formerly known as Helichrysum frigidum (Labill.) Willd. and H. montelinasanum Schmid. In the present paper their morphology is accurately described and compared with that of Helichrysum and related genera. These two species present three morphological characters that are not found together in other Helichrysum species, and which characterise the genus Castroviejoa: the multicellular, biseriate, glandular hairs present on the corolla tube; the undivided stereome; and the apical sweeping hairs that also extend dorsally along the style branches. The full taxonomic treatment of the new genus is provided.

AbstractThe monophyly of the following anthomyiid aggregates is substantiated: The Myopininae/ Myopinini = (Enneastigma Stein + Calythea Schnabl & Dziedzicki) + (Pegoplata Schnabl & Dziedzicki + Myopina Robineau-Desvoidy). The Afrotropical species tarsata (Adams), ornata (Bezzi) and two Oriental species, fulva (Malloch), henanensis (Ge & Fan), all currently recognized in Nupedia Karl, are either referable to Enneastigma or to a new genus in the Enneastigma + Calythea lineage. The recent inclusion of Nupedia in Pegoplata is accepted, but it is pointed out that Pegoplata s. lat. is probably paraphyletic in terms of Myopina. The monophyly of Pegoplata (section cuticornis) is confirmed, and it is argued that its sister group is section acutipennis. Section cuticornis is found to include 1 Holarctic, 2 Nearctic, and 6-7 Palearctic species of which 4 new ones are described from the Mediterranean: P. granadensis sp. n. from Sierra Nevada in Spain, and P. freidbergi sp. n., P. grandis sp. n. and P. hermonensis sp. n. from Mt. Hermon at the Lebanese/Syrian border. The Mediterranean species, which are shown to constitute a monophyletic group, are keyed and subjected to cladistic and biogeographic analyses.

The Mediterranean islands are known as natural laboratories of evolution with a high level of endemic biodiversity. However, most biodiversity assessments have focused mainly on terrestrial and marine fauna, leaving the freshwater animals aside. Crete is one of the largest islands in the Mediterranean Basin, with a long history of isolation from the continental mainland. Gammarid amphipods are often dominant in macrozoobenthic communities in European inland waters. They are widely used in biomonitoring and exotoxicological studies. Herein, we describeGammarus plaitisisp. nov., endemic to Cretan streams, based on morphological characters and a set of molecular species delimitation methods using mitochondrial cytochrome oxidase subunit I and 16S rRNA genes as well as nuclear 28S rDNA, ITS1 and EF1-alpha genes. The divergence of the new species is strongly connected with the geological history of the island supporting its continental origin.

AbstractThe Mediterranean basin is a hotspot of biodiversity, fuelled by climatic oscillation and geological change over the past 20 million years. Wall lizards of the genus Podarcis are among the most abundant, diverse, and conspicuous Mediterranean fauna. Here, we unravel the remarkably entangled evolutionary history of wall lizards by sequencing genomes of 34 major lineages covering 26 species. We demonstrate an early (>11 MYA) separation into two clades centred on the Iberian and Balkan Peninsulas, and two clades of Mediterranean island endemics. Diversification within these clades was pronounced between 6.5–4.0 MYA, a period spanning the Messinian Salinity Crisis, during which the Mediterranean Sea nearly dried up before rapidly refilling. However, genetic exchange between lineages has been a pervasive feature throughout the entire history of wall lizards. This has resulted in a highly reticulated pattern of evolution across the group, characterised by mosaic genomes with major contributions from two or more parental taxa. These hybrid lineages gave rise to several of the extant species that are endemic to Mediterranean islands. The mosaic genomes of island endemics may have promoted their extraordinary adaptability and striking diversity in body size, shape and colouration, which have puzzled biologists for centuries.

AbstractThe importance of the anatomy and fine morphology of reproductive structures for the systematics of the family Parmeliaceae is highlighted by the new genus Notoparmelia, described here for Australasian species of Parmelia. These species were known to form a monophyletic lineage but correlated characters for its delimitation were lacking. A major characteristic used here for the circumscription of this genus is the overlooked apothecial anatomy. The proper exciple is reduced to one layer formed exclusively by large hyphae without any clear branching pattern and embedded in an abundant polysaccharide matrix. This feature differs from the rest of Parmeliaceae which have a stratified three-layered proper exciple composed of a thin hyaline layer, intermediate layer and basal cortex-like structure. The anatomy of proper exciple, together with the thickness of spore walls and other morphological characters such as lobe morphology, pseudocyphellae and rhizine type, allow a precise diagnosis of the new genus. The area of distribution is also useful for characterizing this genus. Sixteen new combinations are proposed.

The generic taxonomy of the Nothofagaceae is revised. We present a new phylogenetic analysis of morphological characters and map these characters onto a recently published phylogenetic tree obtained from DNA sequence data. Results of these and previous analyses strongly support the monophyly of four clades of Nothofagaceae that are currently treated as subgenera of Nothofagus. The four clades of Nothofagaceae are robust and well-supported, with deep stem divergences, have evolutionary equivalence with other genera of Fagales, and can be circumscribed with morphological characters. We argue that these morphological and molecular differences are sufficient for the four clades of Nothofagaceae to be recognised at the primary rank of genus, and that this classification will be more informative and efficient than the currently circumscribed Nothofagus with four subgenera.        Nothofagus is recircumscribed to include five species from southern South America, Lophozonia and Trisyngyne are reinstated, and the new genus Fuscospora is described. Fuscospora and Lophozonia, with six and seven species respectively, occur in New Zealand, southern South America and Australia. Trisyngyne comprises 25 species from New Caledonia, Papua New Guinea and Indonesia. New combinations are provided where necessary in each of these genera.
