On some interesting African katydids (Orthoptera Tettigoniidae)

2016

Results of the study of specimens collected in Africa and preserved in different European collections and museums are reported and extensively illustrated. The tribe Preussiini Karsch, 1890 is resurrected for the genera Preussia Karsch, 1890, Enochletica Karsch, 1896 and Weissenbornia Karsch, 1888. The following three new species are described: Eurycorypha ndokiensis n. sp., Eurycorypha feai n. sp. and Eurycorypha kenyensis n. sp. Rhacocleis dernensis Salfi, 1926 is confirmed in its original genus, Conocephalus algerinorum Massa, 1999 is moved into the subgenus Anisoptera. In addition, new diagnostic characters or distributional data for Horatosphaga crosskeyi Ragge, 1960, Horatosphaga soma…

Megaphylogenetic Specimen-level Approaches to the <I>Carex</I> (Cyperaceae) Phylogeny Using ITS, ETS, and <I>matK</I> Sequenc…

2016

Abstract We present the first large-scale phylogenetic hypothesis for the genus Carex based on 996 of the 1983 accepted species (50.23%). We used a supermatrix approach using three DNA regions: ETS, ITS and matK. Every concatenated sequence was derived from a single specimen. The topology of our phylogenetic reconstruction largely agreed with previous studies. We also gained new insights into the early divergence structure of the two largest clades, core Carex and Vignea clades, challenging some previous evolutionary hypotheses about inflorescence structure. Most sections were recovered as non-monophyletic. Homoplasy of characters traditionally selected as relevant for classification, histo…

A large-scale, higher-level, molecular phylogenetic study of the insect order Lepidoptera (moths and butterflies).

2013

Background Higher-level relationships within the Lepidoptera, and particularly within the species-rich subclade Ditrysia, are generally not well understood, although recent studies have yielded progress. We present the most comprehensive molecular analysis of lepidopteran phylogeny to date, focusing on relationships among superfamilies. Methodology / Principal Findings 483 taxa spanning 115 of 124 families were sampled for 19 protein-coding nuclear genes, from which maximum likelihood tree estimates and bootstrap percentages were obtained using GARLI. Assessment of heuristic search effectiveness showed that better trees and higher bootstrap percentages probably remain to be discovered even …

The DNA barcoding of Mediterranean combtooth blennies suggests the paraphyly of some taxa (Perciformes, Blenniidae)

2019

A dataset including novel and publicly available mtDNA COI sequences of 14 Mediterranean combtooth blenny species belonging to nine genera was assembled in order to provide a reference dataset for DNA barcoding studies. Some inconsistencies in the current taxonomy of some genera were observed. In particular, the monophyly of the genera Parablennius and Salaria is not supported by the present dataset and the absence of reciprocal monophyly between the morphospecies Salaria basilisca and S. pavo questions their status and stresses the need of a revision of the genus Salaria.

New taxa of Orthoptera (Insecta Tettigoniidae Phaneropterinae) from Madagascar.

2017

The author reports the results of a study on Orthoptera collected in Madagascar and preserved in two European Natural History museums. He describes Symmetroraggea depravata n. sp., Parapyrrhicia longipodex n. sp., Madagascarantia bartolozzii n. gen. n. sp., Mimoscudderia spinicercata n. sp. In addition, he lists new records or unknown taxonomical characters of Xenodus nobilis Carl, 1914 and Parapyrrhicia virilis Carl, 1914. 

2016

A working checklist of accepted taxa worldwide is vital in achieving the goal of developing an online flora of all known plants by 2020 as part of the Global Strategy for Plant Conservation. We here present the first-ever worldwide checklist for liverworts (Marchantiophyta) and hornworts (Anthocerotophyta) that includes 7486 species in 398 genera representing 92 families from the two phyla. The checklist has far reaching implications and applications, including providing a valuable tool for taxonomists and systematists, analyzing phytogeographic and diversity patterns, aiding in the assessment of floristic and taxonomic knowledge, and identifying geographical gaps in our understanding of th…

Phytoplankton and its biotic interactions: Colin Reynolds’ legacy to phytoplankton ecologists

2019

The 18th workshop of the International Association for Phytoplankton Taxonomy and Ecology (IAP), the first ‘‘tropical’’ IAP ever, the third one outside Europe, and the first one in South America, was held in Natal, Brazil, from August 27 to September 3, 2017, and its main ecological theme was the Phytoplankton and its biotic interactions. The taxonomic topic of the workshop was chosen based on function instead of phylogeny, and to link to the ecological theme of the workshop, the taxonomic theme was therefore centered on mixotrophic microalgae.

New records of phytoseiid mites from Italy, with description of a new species and a redescription of other two (Parasitiformes, Phytoseiidae)

2020

The Italian phytoseiid fauna consists of 91 valid species. Eighteen of them were described as new species from materials collected in various Italian localities. In the present paper we report nine new records from the Italian fauna and describe the new species, Neoseiulus mediterraneus belonging to the subfamily Amblyseiinae. Complementary descriptions of two rare species, namely: Typhlodromus (Anthoseius) singularis and Typhlodromus (Typhlodromus) knisleyi, were also added.

Pilosella hoppeana subsp. sicula Di Grist., Gottschl. & Raimondo (Asteraceae), a new endemic subspecies from Sicily (Italy)

2016

Abstract Di Gristina, E., G. Gottschlich & F.M. Raimondo (2016). Pilosella hoppeana subsp. sicula Di Grist., Gottschl. & Raimondo (Asteraceae), a new endemic subspecies from Sicily (Italy). Candollea 71: 7–12. In English, English abstract. DOI : http://dx.doi.org/10.15553/c2016v711a2 Pilosella hoppeana subsp. sicula Di Grist., Gottschl. & Raimondo (Asteraceae), a new endemic subspecies from the Madonie and Nebrodi Mountains (Sicily, Italy), is described and illustrated. It is morphologically close to Pilosella hoppeana subsp. macrantha (Ten.) S. Braut. & Greuter, but the two subspecies can be distinguished by the indument on the bracts. Its morphology, distribution, ecology, taxonomic relat…
