Taxonomic catalogue of the family Ochteridae with description of Ochterus papaceki sp. nov. from Socotra Island and Tanzania (Hemiptera: Heteroptera)
2020
The world catalogue of the family Ochteridae (Hemiptera: Heteroptera: Nepomorpha: Ochteroidea) is compiled. The fossil subfamily Propreocorinae Popov, Dolling & Whalley, 1994, recently excluded from Ochteridae by other authors, is formally raised to family rank as Propreocoridae stat. nov. The fossil genus Meropachys Popov, 1986 is found to be a junior homonym of Meropachys Burmeister, 1835 (Hemiptera: Heteroptera: Coreidae) and is replaced by a new substitute name, Yuripachys nom. nov., resulting in one new combination: Yuripachys dubius (Popov, 1986) comb. nov. Neochterus Mahner, 1993 (originally proposed as subgenus of Ochterus Latreille, 1807) is considered an unavailable name. Ocht…
A new Neoplatyura Malloch from Finland (Diptera, Keroplatidae).
2014
The genus Neoplatyura Malloch is globally represented by 50 species, of which four are European species. In this article a new European Neoplatyura from Finland is described. The new species, Neoplatyura noorae Salmela, sp. n. is a dark brown species with tibial bristles arranged in rows. The new species is here reported from seven localities in Finnish Lapland. Based on available data, the new species occurs in mires, especially in calcareous rich fens.
Hypsipyrgias joseliae, a new species of lace bugs (Heteroptera: Tingidae: Tinginae) from New Guinea with a key to species of the genus Hypsipyrgias, …
2021
Hypsipyrgias joseliae sp. n. (Heteroptera: Tingidae: Tinginae) from New Guinea is described, illustrated and compared with its two relatives, namely H. telamonides Kirkaldy, 1908 from Australia, and H. euphues Drake and Ruhoff, 1962 from Lord Howe Island. Key to species of the genus Hypsipyrgias is also provided. Two genera very closely related to Hypsipyrgias Kirkaldy, 1908, namely Hypsotingis Drake, 1960 and Diplocysta Horváth, 1925 are re-diagnosed. Diplocysta globuliformis Hacker, 1928, D. papuana Drake, 1960, D. rustica, Drake, 1960 and D. thaleia Drake and Ruhoff, 1965 are transferred from Diplocysta to Hypsotingis.
Two new genera and species of the Fulviini (Hemiptera, Heteroptera, Miridae, Cylapinae) from Madagascar, with a checklist of Madagascan cylapines
2022
Two new genera, each represented by a single new species, Cassisotropis aciformis Taszakowski et al. gen. et sp. nov. and Infernotropis madagascariensis Taszakowski et al. gen. et sp. nov. are described from Madagascar. Photographs and SEM micrographs of the male and female habitus, genital structures and selected morphological structures are presented. The first record of Fulvius anthocoroides (Reuter, 1875) in Madagascar and the checklist of Madagascan cylapines are also provided.
The regulation of expression of insect cuticle protein genes
2010
International audience; The exoskeleton of insects (cuticle) is an assembly of chitin and cuticle proteins. Its physical properties are determined largely by the proteins it contains, and vary widely with developmental stages and body regions. The genes encoding cuticle proteins are therefore good models to study the molecular mechanisms of signalling by ecdysteroids and juvenile hormones, which regulate molting and metamorphosis in insects. This review summarizes the studies of hormonal regulation of insect cuticle protein genes, and the recent progress in the analysis of the regulatory sequences and transcription factors important for their expression.
Revision of the Eurasian species of Aegilips Haliday, 1835 (Hymenoptera: Figitidae: Anacharitinae)
2022
The knowledge of Aegilips in Eurasia is updated. One new species is described: Aegilips insularis Mata-Casanova and Pujade-Villar sp. nov., from Portugal (Madeira). The genus is also cited for the first time in the Indomalayan region with specimens of A. atricornis found in Northern India and Pakistan. Aegilips curvipes Giraud, 1860, Aegilips gemellus Belizin, 1961, Aegilips laevis (Hedicke, 1914), Aegilips montanus Belizin, 1951 and Aegilips punctatus Belizin, 1951 are synonymized with A. nitidulus (Dalman, 1823). Aegilips vena Fergusson, 1985 is synonymized with Aegilips zaitzevi Kovalev, 1974. Aegilips notatus Belizin, 1951, and Aegilips punctulatus Hedicke, 1928 are designated as incert…
Water striders (Heteroptera: Gerromorpha: Gerridae) of Romania with an update on the distribution of Gerris gibbifer and G. maculatus in southeastern…
2018
The Romanian fauna comprises two species of Aquarius Schellenberg, 1800, eight species of Gerris Fabricius, 1794 and one species of Limnoporus Stål, 1868, and we hereby update the distribution and provide insights on the phenology and ecology of all eleven species in this country. We furthermore update the distribution of the two closely related species Gerris gibbifer Schummel, 1832 and G. maculatus Tamanini, 1946 in southeastern Europe. Gerris maculatus is recorded for the first time from Hungary, Montenegro and Slovenia, and the first detailed localities from Romania and Serbia are given. All bibliographic records of G. gibbifer from Romania, Macedonia and Serbia are based on misidentifi…
Dinotrema cavernicola sp. n. (Hymenoptera, Braconidae, Alysiinae), a new species of the genus Dinotrema Foerster from caves of Spain
2014
Dinotrema cavernicola sp. n. was collected in two caves in Spain. This is the first Dinotrema species known to occur in caves. This new species is described and compared to D. affine (Fischer, 1973) and D. collybiae Munk & Peris-Felipo, 2014, species sharing a mid-longitudinal carina on the propodeum.
A new genus of Phaneropterinae (Orthoptera: Ensifera: Tettigoniidae) from Central Africa.
2014
The new genus Pseudoplangia is described for Plangia laminifera Karsch, 1896. Its general aspect is similar to that of the genus Plangia Stål, 1873, but it differs remarkably in the vertex width, in the shape of eyes, that are oval and elongate, in the length of mid femora, that are shorter than pronotum length, in the shape of fore and mid legs that are very much laterally compressed, and in the presence of broad-based spines on the hind tibiae.
Molecular evolution of the arthropod hemocyanin superfamily.
2001
Arthropod hemocyanins are members of a protein superfamily that also comprises the arthropod phenoloxidases (tyrosinases), crustacean pseudohemocyanins (cryptocyanins), and insect storage hexamerins. The evolution of these proteins was inferred by neighbor-joining, maximum-parsimony, and maximum-likelihood methods. Monte Carlo shuffling approaches provided evidence against a discernible relationship of the arthropod hemocyanin superfamily and molluscan hemocyanins or nonarthropodan tyrosinases. Within the arthropod hemocyanin superfamily, the phenoloxidase probably emerged early in the (eu-)arthropod stemline and thus form the most likely outgroup. The respiratory hemocyanins evolved from t…
