Charipinae (Hymenoptera: Cynipoidea: Figitidae) from Mexico with Description of Three New Species

Abstract Charipinae collected in different regions of Mexico have been studied. Twelve species are cited for the first time: Alloxysta arcuata (Kieffer, 1902), Alloxysta brevis (Thomson, 1862), Alloxysta castanea (Hartig, 1841), Alloxysta fuscicornis (Hartig, 1841), Alloxysta mullensis (Cameron, 1883) ; Alloxysta victrix (Westwood, 1833 ); Phaenoglyphis americanaBaker, 1896; Phaenoglyphis calvertiAndrews, 1978; Phaenoglyphis falcataAndrews, 1978; Phaenoglyphis stenosAndrews, 1978; Phaenoglyphis stricta (Thomson, 1877); and Phaenoglyphis villosa (Hartig, 1841).

Revision of the types of species of Alloxysta described by Cameron and Fergusson (Hymenoptera: Figitidae: Charipinae) and deposited in the Natural Hi…
2013
Type material of the species of Alloxysta described by Cameron and Fergusson and deposited in the Natural History Museum of London has been revised. Seven species are considered valid: Alloxysta abdera Fergusson, 1986, A. basimacula (Cameron, 1886), A. crassa (Cameron, 1889), A. mullensis (Cameron, 1883), A. piceomaculata (Cameron, 1883), A. pleuralis (Cameron, 1879) and A. semiaperta Fergusson, 1986. A. basimacula, A. crassa, A. maculicollis (Cameron, 1886), A. perplexa (Cameron, 1889) and A. piceomaculata are here removed from synonymy with A. macrophadna (Hartig,1841). A. ruficeps (Cameron, 1883) is removed from synonymy with A. victrix (Westwood, 1833). A. caledonica (Cameron, 1886) and…

Figures are provided to show the diagnostic morphological features as used in the keys.
Revision of the Holarctic species of Dilyta Förster (Hymenoptera: Figitidae: Charipinae) with descriptions of four new species from the eastern Palae…
2011
The genus Dilyta, and the known species of this genus present in the Holarctic, D. subclavata Forster from Europe and D. rathmanae Menke and Evenhuis from USA, are redescribed. Four new species of Dilyta are described from the eastern Palaearctic region: D. aleevae sp. n. from Kazakhstan, D. japonica sp. n. from Japan, and D. longinqua sp. n. and D. sinica sp. n. from China. All six species have an ∩ -shaped carina on the apex of the scutellum; this character differentiates these species from the Afrotropical species, which instead have two small symmetrical and parallel carinae. A key to the species of Dilyta in the Holarctic is provided. Apocharips talitzkii (Belizin) is synonymyzed with …

2015
ABSTRACT Charipinae Dalla Torre & Kieffer, 1910 material collected during the ATBI of the Mercantour National Park in the Alpes-Maritimes (France) has been studied. Based on the study of 362 specimens, 35 species in four genera have been identified from: 23 Alloxysta Forster, 1869; 10 Phaenoglyphis Forster, 1869; one Apocharips Fergusson, 1986 and one Dilyta Forster, 1869. Of these, 19 species are recorded from France for the first time: Alloxysta abdera Fergusson, 1986; Alloxysta arcuata (Kieffer, 1902); Alloxysta brachycera Hellen, 1963; Alloxysta brevis (Thomson, 1962); Alloxysta fracticornis (Thomson, 1862); Alloxysta mullensis (Cameron, 1883); Alloxysta pilipennis (Hartig, 1840); Allox…
First Record ofAlloxystaFörster from Madagascar, with Descriptions of Two New Species (Hymenoptera: Cynipoidea: Figitidae: Charipinae)
2012
The genus Alloxysta is recorded for the first time from Madagascar, with the description of two new species: Alloxysta antananarivoi Ferrer-Suay & Pujade-Villar sp. n. and Alloxysta antsirananae Ferrer-Suay & Pujade-Villar sp. n. Their morphological features and diagnostic characters are discussed and illustrated. This is the second genus of the subfamily Charipinae recorded from Madagascar.
Review of the Hartig type collection of Alloxysta (Hymenoptera: Figitidae:Charipinae) and other Alloxysta material deposited in the Zoologische Staat…
2014
Hartig's collection of Alloxysta species, deposited in the Zoologische Staatssammlung Museum (ZSM, Munich, Germany), is here reviewed. In total, 19 species and 144 specimens have been studied. Fourteen species, of the previous twenty-two, are now valid: Alloxysta aperta (Hartig, 1841), A. brachyptera (Hartig, 1840), A. castanea (Hartig, 1841), A. circumscripta (Hartig, 1841), A. fuscicornis (Hartig, 1841), A. leunisii (Hartig, 1841), A. longipennis (Hartig, 1841), A. macrophadna (Hartig, 1841), A. melanogaster (Hartig, 1840), A. obscurata (Hartig, 1840), A. pilipennis (Hartig, 1840), A. postica (Hartig, 1841), A. minuta (Hartig, 1840) and A. rufiventris (Hartig, 1840). These species are red…
<p class="HeadingRunIn"><strong><em>Charybdis glaucophylla</em> (Asparagaceae), a new species from Sardinia</strong><…
2012
Charybdis glaucophylla (Asparagaceae), a new species from Sardinia, is described and illustrated. It is a diploid species with 2n = 20 chromosomes growing along the rocky coast, sandy dunes and mountain top in the south-western part of the island. Within the genus, this species results taxonomically well isolated and differentiated due to relevant morphological and phenological features, such as the leaves wide and short, very rigid and glaucous-pruinose, as well as the very late foliation (winter). It shows only some relationships with C. pancration for the whitish bulb tunics and the diploid chromosome complement, and with C. maura and C. aphylla due to the glaucous leaves.
The vegetation of a historic road system in the suburban area of Monte Pellegrino (Palermo, Sicily)
2020
Knowledge of the processes by which plants colonize old structures is a key element for nature-based design both in urban and suburban contexts. This paper analyses the natural vegetation on walls and in other microhabitats of the roadway structures of Monte Pellegrino (606 m a.s.l.) near Palermo (Sicily), built in the first half of the 1900s. The historical road has particular construction and architectural features, and its characteristics have been maintained to this day. The route, approximately 16 kilometers long, is well integrated within a site of high naturalistic value which has been designated as a Special Area of Conservation (ITA020014) of the Natura 2000 network, and it is also…
The action of TH17 cells on blood brain barrier in multiple sclerosis and experimental autoimmune encephalomyelitis.
2019
Th17 cells, known as a highly pro-inflammatory subtype of Th cells, are involved very early in numerous aspects of multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE) neuropathology. A crucial event for the formation and accumulation of MS lesions is represented by the disruption of the blood brain barrier (BBB) in relapsing-remitting MS. Th17 cells also contribute to the progression of MS/EAE. These events will allow for the passage of inflammatory cells into the brain. Secondary to this, increased recruitment of neutrophils occurs, followed by increased protease activity that will continue to attract macrophages and monocytes, leading to brain inflammation with sus…
