Mittel- und nordeuropäische Weberknechte aus dem Senckenberg Museum Frankfurt (Arachnida: Opiliones)
2005
Central and North European harvestmen from the Senckenberg Museum Frankfurt (Arachnida: Opiliones). About 1100 individuals belonging to 32 opilionid species (300 series), mainly of German origin, were identified based on material provided by, and stored at, the Senckenberg Museum, Frankfurt (Main). A list of all species with habitat information is included. Comments on two remarkable species (Oligolophus hanseni, Odiellus spinosus) are given. The comments include the importance of some series as reference material from MARTENS (1978), additions to regional faunas and the expansion of the known distribution of some thermophilous species.
Determinants essential for the transmissible gastroenteritis virus-receptor interaction reside within a domain of aminopeptidase-N that is distinct f…
1994
The swine-specific coronavirus transmissible gastroenteritis virus (TGEV) uses pig aminopeptidase-N (pAPN) as a cellular receptor. We showed that the human aminopeptidase-N (hAPN) cannot substitute for pAPN in this respect, although the two enzymes have 80% amino acid sequence identity. In order to map the TGEV binding site on pAPN, we constructed a series of APN cDNA chimeras between pAPN and hAPN and analyzed them for their capacity to confer infectivity. The region between residues 717 and 813 was found to be essential for infectivity. This region also contains the epitopes for three TGEV-blocking monoclonal antibodies directed against pAPN. These data support the view that the catalytic…
Interspecific aggression and character displacement in the damselfly Calopteryx splendens
2004
Problems in species recognition are thought to affect the evolution of secondary sexual characters mainly through avoidance of maladaptive hybridization. Another, but much less studied avenue for the evolution of sexual characters due to species recognition problems is through interspecific aggression. In the damselfly, Calopteryx splendens, males have pigmented wing spots as a sexual character. Large-spotted males resemble males of another species, Calopteryx virgo, causing potential problems in species recognition. In this study, we investigate whether there is character displacement in wing spot size and whether interspecific aggression could cause this pattern. We found first that wing …
Species-specific sex pheromones secreted from new sexual glands in two sympatric fungus-growing termites from northern Vietnam, Macrotermes annandale…
2004
Reproductive isolation in termites is not well known. Our study carried out on two sympatric species from northern Vietnam, Macrotermes annandalei and M. barneyi, showed that dispersal flights and sex pheromones were two important factors in their reproductive isolation. These fungus-growing termites were isolated, partially due to the timing of their respective dispersal flights. M. annandalei flew the first day after rain, while the flights of M. barneyi occurred the second day after rain. However, the flights can also be simultaneous in the two species. Sex pheromones of M. annandalei and M. barneyi were shown to be species-specific. In both species, they were secreted by females from tw…
New and little known species of the genus Parapholidoptera Maran (Insecta, Orthoptera)
2009
Material of species of the genus Parapholidoptera Maran is presented. New records of P. noxia (Ramme) are reported from Georgia, P. georgiae sp. n. from Georgia and P. kalashiani sp. n. from Armenia are described. P. syriaca is newly reported from Lebanon.

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…
