Paraplangia sinespeculo, a new genus and species of bush-cricket, with notes on its biology and a key to the genera of Phaneropterinae (Orthoptera: T…
2018
Madagascar is a well-known hotspot of biodiversity. However, many Orthoptera, and especially the Tettigonioidea, belong to little-studied groups. Here we describe a new genus and species of bush-cricket reared from field-collected eggs.Paraplangiasinespeculogen. nov., sp. nov. belongs to Phaneropterinae and shares diagnostic characteristics with members of the tribe Amblycoryphini and its African subtribe Plangiina stat. nov.Paraplangia, which has a chromosome number of 31 X0, differs from other African members of the tribe and subtribe such asEurycoryphaandPlangia, which both have 29 X0. In addition to morphology, we describe the male calling song, female acoustic response, and mating beha…
Study of a New Population of the Argentinian Endemic Species Riella choconensis Hässel (Riellaceae, Marchantiophyta) Reveals a Novel Anatomical Struc…
2019
A new population of the Argentinian endemic Riella choconensis Hässel (Riellaceae, Marchantiophyta) was discovered from a culture of sediments from the Laguna de los Juncos (Río Negro province, Argentina). This species was known previously from two nearby collections, made in 1984, in the type locality at the Ramos Mexía reservoir (Neuquén province) and was not recorded since. Fresh material from the new population enabled detailed morphological analyses, which are extensively described here, illustrated and compared to type material of the species. Based on the smooth female involucre, the species belongs to subgenus Riella Mont. However, cross-sections of this structure showed that R. cho…
Comparative biogeography of echinoids, bivalves and gastropods from the Southern Ocean.
2013
ABSTRACTAim Biogeographical patterns within three classes, the Echinoidea, Bivalvia andGastropoda, were investigated in Antarctic, sub-Antarctic and cold-temperateareas based on species occurrence data. Faunal similarities among regions wereanalysed to: (1) test the robustness of the biogeographical patterns previouslyidentified in bivalves and gastropods; (2) compare them with the biogeographi-cal patterns identified for echinoids; and (3) evaluate the reliability of the bio-geographical provinces previously proposed, depending on the taxa andtaxonomic levels analysed.Location The Southern Ocean, sub-Antarctic islands and cold-temperate areassouth of 45° S latitude at depths of < 1000 m.Meth…
<p><strong>Cytotaxonomical remarks on <em>Loncomelos visianicum </em>(Hyacinthaceae), a poorly known species endemic to Croat…
2020
Loncomelos visianicum, a rare and poorly known geophyte of the Croatian flora, was described from the remote and uninhabited Adriatic island of Palagruža as Ornithogalum visianicum, and it has not been collected again for over a century. Basing on living materials, recently rediscovered in the locus classicus, it was possible to carry out a careful investigation regarding the morphology, karyology, leaf anatomy, and ecology of this very peculiar species. It is triploid, showing 2n = 42 + 0–5B chromosomes, taxonomically quite isolated, showing some morphological relationships with L. narbonense and L. creticum. Currently, L. visianicum is represented by a low number of individuals growing in…
Relationships between helminth communities and diet in Canarian lizards: the evidence from Gallotia atlantica (Squamata: Lacertidae)
2014
Diet and helminth fauna were analysed in the lizard Gallotia atlantica (Squamata: Lacertidae), the smallest species of this genus endemic to Lanzarote and Fuerteventura (Canary Islands), in an attempt to confirm previous claims of relationships between these ecological traits in this genus. A total of 70 lizards belonging to the subspecies atlantica (central southern Lanzarote), laurae (northern Lanzarote) and mahoratae (Fuerteventura) were examined. Compared with other Gallotia, the helminth fauna was impoverished, particularly in Fuerteventura, where the absence of larval cestodes suggests low predation pressure. Diet was omnivorous, the plant fraction (73.03–84.26%) included seeds and fr…
Three endemic Aphaenogaster from the Siculo-Maltese archipelago and the Italian Peninsula: part of a hitherto unrecognized species group from the Mag…
2019
Abstract More than 100 years ago, the Italian myrmecologist Carlo Emery described two endemic Sicilian ants: Aphaenogaster sicula Emery, 1908, which he originally considered a subspecies of A. crocea André, 1881, and A. fiorii Emery, 1915 stat. nov., which he believed was a subspecies of A. gibbosa (Latreille, 1798). Males of the two species and the queen of A. fiorii were never described. The scarcity of information contained in the original description led to several misunderstandings by subsequent authors: for example, A. sicula was later elevated to species-rank on the basis of misidentified material of A. fiorii stat. nov. We redescribe the two species, adding the descriptions of their…
A new species of Pamphagus (Orthoptera: Pamphagidae) from Algeria with a key to all the species of the genus
2017
The authors describe Pamphagus milevitanus n. sp. occurring in the North and South highlands of Constantine, in Mila, Setif and Oum-el Bouaghi provinces, where it is fairly common. They compare the characters of this species with those of the most related species of the genus and present a complete plate and a key to all the species of the genus Pamphagus known to date.

Review of the African genera Arantia Stål and Goetia Karsch (Orthoptera: Tettigoniidae: Phaneropterinae)
2017
The genus Arantia is reviewed, the distribution and distinguishing characters given. The three species of Goetia are assigned as subgenus to Arantia. Arantia gestri Griffini is transferred to this new subgenus and synonymized with G. dimidiata Bolívar. Other species synonymized are: A. accrana Karsch with A. rectifolia Brunner von Wattenwyl; A. gabunensis Brunner von Wattenwyl with A. regina Karsch; A. mammisignum Karsch and A. tigrina Bolívar with A. excelsior Karsch; A. ugandana Rehn is synonymized with A. fasciata (Walker). 6 species from Tropical Africa are newly described: A.
