The enigmatic case of the genus Argyresthia in the Azores Islands (Lepidoptera Argyresthiidae)
2020
The species composition of the genus Argyresthia Hübner, 1825 in the Azores is examined. Argyresthia brumella, sp. nov., is described and illustrated from Terceira and Flores Islands. Argyresthia minusculella Rebel, 1940, syn. nov. and Tinea poecilella Rebel, 1940, syn. nov. are synonymized with Argyresthia atlanticella Rebel, 1940. The high variability of A. atlanticella is revealed through the polymorphic wing pattern and the intraspecific genetic divergence of the DNA barcode COI in the specimens examined.
Revision of the plant bug genus Xenocylapus Bergroth (Hemiptera: Heteroptera: Miridae: Cylapinae), with a description of Henryfulvius gracilis – a ne…
2014
SummaryThe genus Xenocylapus Bergroth, 1922 is revised. Nine new species, Xenocylapus aculeatus sp. nov., X. aquilonius sp. nov., X. bicolor sp. nov., X. globulus sp. nov., X. heissi sp. nov., X. panamaensis sp. nov., X. serrulatus sp. nov., X. tenuis sp. nov., and X. waorani sp. nov., are described from Brazil, Honduras, Mexico, and Panama. New genus and species Henryfulvius gracilis gen. nov., sp. nov. is described from Ecuador. Illustrations of the male genitalia, color photographs of dorsal and lateral views of the adult of most species, scanning electron micrographs of selected structures of X. tenuis, and keys to species of the genus Xenocylapus are provided.
Tettigoniidae (Orthoptera) from Jordan with description of new species and redescription of less known species
2001
Twenty species of Tettigoniidae are recorded from Jordan, 13 of them for the first time. Two new species are described, Uvarovistia rammei and Parapholidoptera willemsei. New status is proposed for Paradrymadusa philbyi Uvarov (= Scotodrymadusa philbyi) and for Platycleis (Incertana) erecta Uvarov (= Platycleis (Decorana) erecta).
Generic concept of the phytoseiids (Acari: Phytoseiidae) according to Athias-Henriot
2010
The economic importance of the Phytoseiidae motivated many scientists to work on the systematics of this family. One of them was the French acarologist Claire Athias-Henriot. In her first work, she tackled the question of supraspecific groupings within this family from an evolutionistic point of view, and suggested a system for numbering dorsal shield setae, that could be applied to both hypotrichous and holotrichous forms. She also looked for other characters, such as the ratios of the distance between the insertions of some setae on dorsal and sternal shields, the presence of macrosetae on legs, and the length/width ratio of the ventrianal shield. Following Dosse (1957; 1958) who used the…
World revision of the genus Encyrtoscelio Dodd (Hymenoptera: Scelionidae)
1995
The genus Encyrtoscelio Dodd is revised. E. apterus (Szelényi), E. mirissimus Dodd, E. turneri Waterston are redescribed, and six new species are described: E. cydni Caleca, E. japonicus Caleca, E. mediterraneus Caleca, E. miroides Caleca, E. spuratus Caleca and E. undecim Caleca. A key to separate females is presented, and is based on the number of antennomeres and claval sensillar formula, mandibular spurs and teeth, palpal formula and clypeus, and some cephalic characters. Morphological adaptations of the head and mandibles are discussed in relation to host habitat and oviposition site. Information on host associations, habitat preference, seasonal and daily occurrence of some species a…
PENIS MORPHOLOGY IN ONCOPODIDAE (OPILIONES, LANIATORES): EVOLUTIONARY TRENDS AND RELATIONSHIPS
2002
Abstract An interim report on our ongoing revisional study is given together with a short summary of the current knowledge on the systematics and distribution of the family Oncopodidae (Opiliones, Laniatores). An exceptionally high diversity in male genitalia is shown and its possible evolution is discussed. Four major penis types are distinguished in the Oncopodidae and compared with similar forms in other laniatorean families.
A new species of glirid rodent Vasseuromys from the Aragonian (Miocene) of the Ebro Basin (North−Eastern Spain)
2012
We describe a new species of Vasseuromys from the locality of Pico del Fraile 2 (PF2) in the Ebro Basin of northeastern Spain, which has yielded a fauna comprising several rodents and insectivores (Eumyarion cf. weinfurteri, Mega−cricetodon cf. primitivus, Democricetodon aff. hispanicus, Spermophilinus cf. besana, Microdyromys cf. legidensis, Galerix sp., and Lagomorpha indet.) indicative of Aragonian zones C or D. Vasseuromys cristinae sp. nov. differs from other Vasseuromys species in the constant presence of four extra ridges on the lower molars, one of them being connected to the posterolophid in the posterior valley, as well as three extra ridges on the upper molars, with none of them …
Dinosaur bonebed amber from an original swamp forest soil
2021
AbstractDinosaur bonebeds with amber content, yet scarce, offer a superior wealth and quality of data on ancient terrestrial ecosystems. However, the preserved palaeodiversity and/or taphonomic characteristics of these exceptional localities had hitherto limited their palaeobiological potential. Here we describe the amber from the Lower Cretaceous dinosaur bonebed of Ariño (Teruel, Spain) using a multidisciplinary approach. Amber is found in both a root layer with amber strictly in situ and a litter layer namely composed of aerial pieces unusually rich in bioinclusions, encompassing 11 insect orders, arachnids, and a few plant and vertebrate remains, including a feather. Additional palaeont…
<p class="HeadingRunIn"><strong>The genus <em>Uracrobates</em> (Acari, Oribatida, Mochlozetidae)</strong></p>
2015
Uracrobates (Parauracrobates) truncatus sp. nov. is proposed, based on specimens from soil in Nepal. Parauracrobates subgen. nov. is distinguishable from subgenus Uracrobates by the notogaster truncated posteriorly (versus conical). An identification key to known taxa in the genus Uracrobates is given.
The Taxon Rasivalva (Hymenoptera: Braconidae) in the Palaearctic Region and Description of Rasivalva pyrenaica New Species from Andorra
2005
Rasivalva appears to be an uncommon genus, although it is nearly cosmopolitan with the exception of the Australian continent. Five species have been recorded from Europe and Crimea. In this paper, Rasivalva pyrenaica n. sp. is described as the most southern Palaearctic record of this genus, as well as the first record of the genus from Iberian Peninsula. An identification key is proposed for the Palaearctic species.
