Molecular phylogeny of Iberian Fordini (Aphididae: Eriosomatinae): implications for the taxonomy of generaFordaandParacletus
2009
Mediterranean representatives of the galling aphid tribe Fordini (Hemiptera: Aphididae: Eriosomatinae) are usually grouped under the subtribe term Fordina. Aphids within Fordina display two-year life cycles, alternating between Pistacia shrubs, where they induce conspicuous galls, and roots of Poaceae species. The high number of morphs present in a given species, the lack of knowledge of the complete cycle in some species, and the similarity between homologous morphs observed in different species pose many taxonomic problems in this group. We present results of a survey to elucidate the phylogenetic relationships among Fordini species present in the Iberian Peninsula and the Canary Islands.…
A new Aphid genus and species (Hemiptera: Aphididae: Macrosiphini) living on ferns in Costa Rica and Mexico
2013
AbstractAphid species colonising ferns belong to the subfamily Aphidinae (Hemiptera: Aphididae) and the majority of these to the tribe Macrosiphini. A new genus in this tribe and its type species: Gibbomyzus pteridophytorumnew genus, new species, are established. Apterous and alate viviparous females are described from specimens collected on Blechnum buchtienii Rosenstock (Blechnaceae) in Costa Rica and on Pteridium aquilinum (Linnaeus) Kuhn (Dennstaedtiaceae) and an unidentified fern in Mexico. The taxonomic validity of the two new taxa is discussed based on morphological and molecular data. Morphologically, the new genus is compared with genera with swollen siphunculi recorded in the New …
Trioxys liui Chou & Chou, 1993 (Hymenoptera, Braconidae, Aphidiinae): an invasive aphid parasitoid attacking invasive Takecallis species (Hemiptera, …
2020
Biological invasion of aphids and other insects has been increased due to long distance commercial transportation of plant material. The bamboo-aphid-parasitoid association is strictly specific and even though it does not develop interactions with the local environment it should be listed as part of the fauna of southwestern Europe. On-going research regarding aphids and their aphidiine parasitoids in Spain has yielded a new association of Trioxys liui Chou & Chou, 1993 with an undescribed species of Takecallis aphids on bamboo, Phyllostachys spp. Here we present the first association of T. liui with aphids of the genus Takecallis that attack bamboos. Trioxys liui is known as a parasitoid o…
A new parasitoid (Hymenoptera: Braconidae: Aphidiinae) of the invasive bamboo aphidsTakecallisspp. (Hemiptera: Aphididae) from Western Europe
2017
ABSTRACTA long-term survey of tritrophic (plant–aphid–parasitoid) associations in the urban ecosystems of Lleida (Catalonia) and Paris (France) resulted in the detection of associations of two bamboo aphids, Takecallis arundinariae (Essig) and Takecallis taiwanus (Takahashi), respectively, with a new aphid parasitoid species. Trioxys remaudierei Starý & Rakhshani sp. nov. is described and illustrated as a unique parasitoid of Takecallis aphids outside the area of their origin. The new species is easily distinguishable from its congeners in having the ventral prongs of the abdomen fused over two-thirds of their length, then bifurcated towards the tip. The only morphologically similar species…
Contribution to the knowledge of North-American species Hyperomyzus subgenus Neonasonovia (Aphididae, Aphidinae, Macrosiphini)
2017
American specimens of the Hyperomyzus subgenus Neonasonovia conserved in the collections of the Museum national d’Histoire naturelle (Paris, France) and the Natural History Museum (London, United Kingdom), have been studied. Data to complement previous descriptions of apterous and alate viviparous females of H. nabali and of apterous viviparae of H. nigricornis, H. inflatus, H. niger and H. pullatus , are presented. Apterous and alate virginogeniae females of H. nigricornis, alate viviparous females of H. inflatus, H. niger and H. pullatus, plus oviparous females of H. nabali , are described for the first time. The morphological and biological variability of H. pullatus is discussed. An ide…
Brachyptery analysis in Alloxysta (Hymenoptera: Figitidae): Synonymy of A. curta Ferrer-Suay and Pujade Villar as the brachypterou of A. ramulifera (…
2022
Eight brachypterous species have been described within the hymenopteran genus Alloxysta. Intraspecific wing polymorphism linked to sex has been previously hypothesized within this genus and the aim of this work was to confirm whether the phylogenetic relationships based on morphological characters between brachypterous and macropterous species are correct using molecular analyses. This study used material collected from Minnesota (USA), with 278 specimens identified as Alloxysta brachyptera (Hartig, 1840), A. curta Ferrer-Suay and Pujade-Villar, 2017 (Ferrer-suay et al. 2017), A. brevis (Thomson, 1862), or A. ramulifera (Thomson, 1862). Twenty-three of these specimens were subjected to sequ…
Integrative taxonomy of root aphid parasitoids from the genus Paralipsis (Hymenoptera, Braconidae, Aphidiinae) with description of new species
2019
Species from the genus Paralipsis are obligatory endoparasitoids of root aphids in the Palaearctic. It is known that these species are broadly distributed, parasitizing various aphid hosts and showing great biological and ecological diversity. On the other hand, this group of endoparasitoids is understudied and was thought to be represented by a single species in Europe, viz., Paralipsisenervis (Nees). However, recent description of two new species indicated the possibility of cryptic speciation and recognition of additional Paralipsis species in Europe. In this research, Paralipsis specimens collected during the last 60 years from eight European countries, as well as one sample from Morocc…
A new species of Rhopalosiphum (Hemiptera, Aphididae) on Chusquea tomentosa (Poaceae, Bambusoideae) from Costa Rica
2012
copyright 2012, Los autores y Zookeys. Datos incluidos por Lisela Moreira Carmona, responsable de depósitos del área de Patógenos y Plagas de Plantas (CIBCM-UCR). The new species Rhopalosiphum chusqueae Pérez Hidalgo & Villalobos Muller, is described from apterous viviparous females caught on Chusquea tomentosa in Cerro de la Muerte (Costa Rica). The identity of the species is supported both by the morphological features and by a molecular phylogenetic analysis based on a fragment of the mitochondrial DNA containing the 5’ region of the cytochrome c oxidase 1 (COI) and on the nuclear gene coding for the Elongation factor-1 alpha (EF1α). The taxonomic position of the new species is discussed…
A molecular study of Neophyllaphis varicolor (Hemiptera, Aphididae) in Costa Rica
2019
The genus Neophyllaphis (Takahashi) (Aphididae: Neophyllaphidinae) is composed of 18 species; however, in the Americas only nine species have been reported previously. A new species, Neophyllaphis varicolor Miller & Halbert, was described in 2014 in USA. Colonies resembling those of this new species have been observed in Costa Rica on Podocarpus spp. In order to determine if N. varicolor is also present in Costa Rica, we sampled Neophyllaphis colonies from Podocarpus falcatus and P. chinensis. Additionally, we sampled individuals from Podocarpus sp. in Spain and Vietnam. DNA of each sample was extracted and used to amplify and sequence the cytochrome c oxidase subunit I (COI) and elongation…
Worldwide revision of the genus Phaenoglyphis (Hymenoptera, Cynipoidea, Figitidae, Charipinae)
2019
A complete revision of the world species of the genus Phaenoglyphis Förster, 1869 has been conducted. A total of 25 species of Phaenoglyphis are valid after studying their type material. Two new species are described: Phaenoglyphis belizini sp. n. and Phaenoglyphis palmirae sp. n. Two species are synonymized: P. dolichocera (Cameron, 1889) with P. nigripes (Thomson, 1877) and P. pecki Andrews, 1978 with P. villosa (Hartig, 1841). Phaenoglyphis bangalorensis Kurian, 1953 was considered as incertae sedis. Phaenoglyphis duplocarpentieri (Kieffer, 1904) and P. hedickei Hedicke, 1928 are considered lost. Other three species are discarded as valid species because they are missing important parts …
