The present paper describes sensory structures on the apical segment of labium in representatives subfamily Peiratinae (Heteroptera: Reduviidae), using scanning electron microscope. study is based dry material representing 19 species and 16 genera. Within thirteen morphologically distinct types sensilla were identified. Among them four new (porous placodea sensillum [PPLS], multilobate [MS], domeelongated [UDES], pit peg type 2 [NPPS2]) found. Mechanosensilla are evenly distributed surface...

Madagascar is one of the world's most recognized biodiversity hotspots and has a diverse assassin bug (Reduviidae) fauna that still incompletely known, especially for Ectrichodiinae, or millipede bugs. Ectrichodiinae are speciose (673 described species, 118 genera), worldwide group bugs in Old New World tropics, but so far only six genera 10 species have been from Madagascar. Based on examination 1981 ectrichodiine specimens mostly California Academy Sciences, as well few other collections,...

Abstract At least a dozen species of aphids (Insecta, Hemiptera) non-native origin have expanded their range in Europe, however the importance botanic gardens this phenomenon has not been studied previously detail. As case study, investigations on composition and host Aphidomorpha Royal Botanic Gardens, Kew, London, United Kingdom, were conducted over period twelve days, June 2017.

Our research were based on 262 specimens museum collections P. species a set 23 environmental predictor variables, all recorded in 1x1 km grid covering Africa. Ecological niche modelling performed using MAXENT analyses to produce predictive potential distribution maps for its colour forms separately. results...

Two P. mirabilis guilberti described. A key to is also provided.

Abstract During our previous morphological and molecular studies, as well modelling the environmental niche preferences of genus Sirthenea Spinola, (Peiratinae), distribution species S. flavipes (Stål, ) became one most interesting issues. This has a very broad range covering southern part western, central eastern Asia. We observed two distinct types colouration, each also exhibiting certain degree variability. Although both colour forms studied show similar variability, differences between...

Mangabea troglodytes sp. nov. (Hemiptera: Heteroptera: Reduviidae: Emesinae) is described based on four specimens collected in a cave of the Namoroka Karstic System, Madagascar, and deposited Collection Muséum National d'Histoire Naturelle, Paris. The dorsal habitus as well diagnostic characters male female genitalia are extensively illustrated imaged. A key to species genus Villiers, 1970 provided degree specialization new discussed.

Planeocoris, a new genus and one species P. redeii, are described based on single specimen from Madagascar selected undetermined materials of the Collection Muséum National d’Histoire Naturelle, Paris. The dorsal habitus as well diagnostic characters male genitalia illustrated with 17 figures.

We report for the first time presence of globally distributed and extremely polyphagous pest species—the crescent-marked lily aphid (or mottled arum aphid) (Neomyzus circumflexus L.) (Insecta, Hemiptera, Aphididae)—in Greenland. This species, alien origin, was found on ornamental plant Salix arbuscula L., imported from Denmark sold in main supermarket Nuuk, capital As this species is not preferred host N. circumflexus, possibility must be considered that aphids were along with S. mainland...

Physoderoides linnavuorii sp. nov. (Hemiptera: Heteroptera: Reduviidae: Physoderinae) is described based on one male specimen from Madagascar deposited in the Muséum National d'Histoire Naturelle, Paris. The dorsal habitus, morphological characters of legs as well genitalia are illustrated. In addition, a key for identification species Miller, 1955 provided.

Abstract Genus Platymeris Laporte, 1833 is a medium‐sized genus belonging to the subfamily Reduviinae, and all known species of these assassin bugs are large‐sized insects, distributed exclusively in Africa. Among them, two species, biguttatus rhadamanthus , particularly well for being bred commercial cultures. Representatives both were crossed laboratory conditions resulting interspecific hybrids. The offspring genetically tested confirm their hybridisation by nuclear analysis wingless...

Myrmicella verticospinosa gen. et sp. nov., is described, based on four specimens (two males and two females) collected in south-west Madagascar (Zombitse-Vohibasia National Park Isalo Park). Three have been by sifting the leaf litter, one female was using yellow pan traps. Genitalia of both sexes are described illustrated.

Although the high Arctic archipelago Svalbard is among best-studied regions in terms of biodiversity, its aphid fauna extremely limited. Two endemic species have been described to date, and no a foreign origin has registered. Our observation first record non-native potentially invasive green-peach Myzus (Nectarosiphon) persicae (Insecta, Hemiptera, Aphididae), which was collected on largest island archipelago—Spitsbergen. The found three different ornamental plants: Viola tricolor...

Abstract The Arctic aphids live briefly and must breed quickly to survive. Shortened life cycle, with only two generations: the stem mother sexuales—oviparous females males is an adaptation for optimal use of short breeding period, which lasts from late July end August. Using Acyrthosiphon svalbardicum, endemic High aphid species, we describe structure reproductive system sexual morphs compare its temperate counterparts, in particular model organism pea pisum. Generally, histological...

Peyrierocoris seyrigi (Villiers, 1970) is redescribed and its taxonomic position revised to accommodate Vesbius Villiers, 1970, erroneously described under the generic name Stål, 1865.

Two new species, gorczycai sp. nov. herczeki nov., illustrated with 21 figures.

Henicocephaloides raunoi sp. nov. (Hemiptera: Heteroptera: Reduviidae: Physoderinae) is described based on a single male specimen from Eastern Madagascar, which deposited in the collection of Moravian Museum, Brno.

Two new species of reduviids from Madagascar, namely Hendecacentrus simulans sp. nov. and Antanambeus marmoratus nov., are described based on single male specimens deposited with the Muséum national D’Histoire naturelle, Paris. Key to these two genera is also provided. Voucher material Distributional data other given.

Abstract Species identification within the aphid genus Pemphigus Hartig, 1839 poses challenges due to morphological similarities and host-plant associations. Aphids of this generally exhibit complex life cycles involving primary hosts (poplars) secondary (mostly unrelated herbaceous) host-plants, with some species relying solely on root-feeding generation. An example is a representative , trophically associated grass roots, found in High Arctic Svalbard archipelago. Historical records...
