Attagenus Latreille, 1802 (Coleoptera: Dermestidae: Attageninae) in Turkey with a description of a new species

A new species of the large genus Attagenus Latreille, 1802, A. hadesi sp. n. from Turkey is described and illustrated. Morphological characteristics useful for identification are provided. A list of species of Attagenus from Turkey is also given

Anthrenus (Florilinus) loebli n. sp. (Coleoptera, Dermestidae, Anthrenini) from the Middle East

A new species Anthrenus (Florilinus) loebli from Israel, Lebanon and Jordania is described, illustrated and compared with the similar species classified within the subgenus Florilinus Mulsant & Rey, 1868. The new species is characterized by oval eyes, eight-segmented antenna and subtriangular, occasionally triangular, scales on the dorsum. The yellowish/light brown scales are present on the anterior and terminal part of the elytra and create three irregular, transverse bands. Antennal segment eight are at least 4.8 to 5x longer than segment 7 in male, 2.1x longer in female. The new species is most similar to A. (F.) museorum (Linnaeus, 1761); A. (H.) fuscus Olivier, 1789 and A. (F.) flavidus Solsky, 1876. An identification key to externally similar species of the genus is given. The most distinctive taxonomic characteristics concern the male genitalia and antenna (in ratio of length of segments of antennal club) and are also described

Redescription of Anthrenus (s. str.) flavidulus Reitter, 1889, and a new synonym in Palaearctic Anthrenus Geoffroy, 1762 (Coleoptera: Dermestidae)

The comparison of the morphology of the dorsal patterns, aedeagus, sternite IX and mouthparts of Anthrenus (s. str.) miniatulus Reitter, 1899 and Anthrenus (s. str.) flavidulus Reitter, 1889 proved that they belong to the same species. A photo of each adult form and male genitalia is provided. The name Anthrenus miniatulus Reitter, 1899 is proposed to become a junior synonym of Anthrenus flavidulus Reitter, 1889. Since Anthrenus miniatulus have also been found in Syria, the country name is now added to the distribution list of Anthrenus flavidulus

Occurrence, ecological function and medical importance of dermestid beetle hastisetae

Hastisetae are a specific group of detachable setae characterizing the larvae of Megatominae (Coleoptera: Dermestidae), commonly known as carpet and khapra beetles. These setae are located on both thoracic and abdominal tergites and they are the primary defense of the larva against invertebrate predators. According to previous studies, the main purpose of hastisetae is to work as a mechanical obstacle, but they are also capable to block and kill a predator. Hastisetae, single or aggregate, function as an extremely efficient mechanical trap, based on an entangling mechanism of cuticular structures (spines and hairs) and body appendages (antennae, legs and mouthparts). It is believed that this defensive system evolved primarily to contrast predation by invertebrates, however it has been observed that hastisetae may affect vertebrates as well. Although information on the impacts of vertebrate predators of the beetles is lacking, hastisetae have been shown to be a possible threat for human health as an important contaminant of stored products (food and fabric), work and living environment. Review of past and recent literature on dermestid larvae has revealed that despite these structures indicated as one of the distinctive characters in species identification, very little is known about their ultrastructure, evolution and mechanism of action. In the present work, we will provide the state of knowledge on hastisetae in Dermestidae and we will present and discuss future research perspectives intended to bridge the existing knowledge gaps

Tureckie prawo ochrony konkurencji – zagadnienia wybrane

W niniejszym artykule przedstawiono wybrane zagadnienia prawa ochrony konkurencji obowiązujące w Turcji, państwie, które od wielu lat, do tej pory bezskutecznie, pretenduje do wstąpienia w poczet członków UE. Publikacja ta ma na celu przybliżenie Czytelnikom regulacji prawnych zarówno o charakterze materialnoprawnym (cel ustawy antymonopolowej, jej zakres przedmiotowy, organy odpowiedzialne za egzekwowanie zakazów praktyk ograniczających konkurencję, charakter sankcji nakładanych na przedsiębiorstwa za naruszenie prawa antymonopolowego), jak i przepisów o charakterze procesowym (tryb postępowania, prawa i obowiązki podmiotów biorących w nim udział). Opracowanie zawiera także informacje dotyczące dochodzenia odszkodowania na drodze cywilnej przez podmioty, które poniosły szkodę na skutek działań stanowiących zakazane praktyki ograniczające konkurencję (private enforcement)

The pollination of Epipactis Zinn, 1757 (Orchidaceae) species in Central Europe – the significance of chemical attractants, floral morphology and concomitant insects

A series of studies on pollination biology of the Epipactis atrorubens (Hoffm.) Besser, E. purpurata Sm., and E. palustris (L.) Crantz populations was conducted in Poland, Lithuania and Czech Republic between 2003 and 2010. The research focused on pollinators and visitors to aforementioned orchid species as well as on the chemical analysis of orchids' nectar which was done using the GC/MS method. It was found that: 1) the type of pollinators depends on the orchid population size and the surrounding environment, where the temperature and amount of precipitation during the vegetative season are the most vital factors; 2) pollinators and visitors to the examined orchids might differ in successive growing seasons; 3) the studied Epipactis species differ in the chemical composition of their nectar and its scent, which can influence their pollination biology; 4) the tendency to autogamy observed in E. purpurata might be due to lack of pollinators in its habitats

A review of the Attagenus (Coleoptera: Dermestidae) species from South Africa and an image-based key to identification

The Dermestidae is a relatively poorly studied family of insects but with a high rate of species discovery. The South African region is particularly rich in Attagenus spp. many of which are distinctively patterned. This study provides an updated list of Attagenus spp. in South Africa with a complete literature review and an image-based identification key to the Attagenus species within South Africa. Images of most species are provided. With the rise in significance of citizen science recording schemes, this study facilitates image-based identification and encourages both entomologists and citizen scientists to further contribute to the understanding of this beautiful Coleopteran family

Axillary lymph node and early breast cancer diagnostics. A case report

Understanding of the anatomy of the axillary lymph nodes is important in diagnostic and treatment procedures for breast cancer. An interesting case is presented here of breast cancer without a breast tumour. The first symptom of the disease was lymphadenopathy of the axillary region. This kind of case is extremely rare in clinical practise (one case per 1-5 years) and constitutes a great problem for specialists, since in many cases the primary neoplasm source is unknown. The anatomical and clinical implications of such a situation are discussed
