<p><strong><em>Chilocoris</em> <em>serratus</em> n. sp., the first burrower bug species (Hemiptera: Heteroptera: …
2016
The first burrower bug species recorded in Guinea-Bissau, Chilocoris serratus n. sp., is described and compared with morphologically related species. Additionally, an annotated checklist of Afrotropical species of the genus Chilocoris is provided.
Chilamnestocoris mixtus gen. et spec. nov., the first burrower bug (Hemiptera: Pentatomoidea: Cydnidae) in Upper Cretaceous Burmese amber
2018
Abstract A new genus and species of burrower bug, Chilamnestocoris mixtus gen. et sp. nov. (Hemiptera: Cydnidae), is described from Upper Cretaceous Myanmar amber. The new genus is characterized by a very long claval commissure and, therefore, is classified within the extant subfamily Amnestinae. It presents a mixture of generic characters relevant to the genus Chilocoris Mayr (Cydninae) and the genus Amnestus Dallas (Amnestinae), but also has its own autapomorphies, i.e., each cephalic marginal setigerous puncture arises from its own well-developed tubercle, and the middle and posterior tibiae are strongly compressed and flattened.
Another alien bug in Europe: the first case of transcontinental introduction <br />of the Asiatic burrower bug Macroscytus subaeneus (Dallas, 1…
2019
The Oriental burrower bug Macroscytus subaeneus (Dallas, 1851) (Hemiptera: Heteroptera: Cydnidae: Cydninae), presently known only from single localities in Flores (Indonesia), the Philippines and Thailand, is recorded from the United Kingdom (hereafter U.K.). A single female specimen was collected on the semi-rural edge of Bath city by a Starling (Sturnus vulgaris L.) and taken to its nest from which it was retrieved during 2015. The specimen is illustrated and its diagnostic characters are provided. We hypothesize that this specimen could have been imported with a shipping container from Thailand.
<p><strong>In BOLD we trust? A commentary on the reliability of specimen identification for DNA barcoding: a case study on burrower bugs …
2016
An assessment was performed regarding the accuracy of various types of data deposited in the Barcode of Life Data system (BOLD) related to the true bug family Cydnidae (Hemiptera: Heteroptera). Taxonomic nomenclature and classification, identification reliability, and the correctness of the data provided in the "Taxon description" were analyzed and commented on with respect to both available versions of the BOLD system, i.e. version 3 and beta version 4. Numerous mistakes in taxonomy, the relevance of the taxa names, and species misidentifications in BOLD version 3 were found and, more importantly, similar errors were detected in BOLD version 4 as well. We suggest that if the BOLD system is…
Presence of uradenia in male adults of the genus Dismegistus (Hemiptera: Heteroptera: Parastrachiidae)
2018
Uradenia, often referred to as paragenital glands, are usually voluminous paired exocrine glands located ventrally in the abdomen mostly on the intersegmental membrane between abdominal segments (= urites) VII-VIII or VIII-IX, depending on sex or the taxon. They have been previously recorded from eight pentatomomorphan families belonging to Coreoidea, Lygaeoidea and Pyrrhocoroidea (Hemiptera: Heteroptera), found either in males, females or both sexes, and were thought to be absent in Pentatomoidea. We report here the first instance of uradenia in a pentatomoid genus, the African Dismegistus Amyot & Serville, 1843 (Parastrachiidae). Only the male adult possesses uradenia located on the i…
<strong><em>Amnestus mendeli</em> sp. n., the first burrower bug species (Hemiptera: Heteroptera: Cydnidae) recorded on Ascension I…
2016
A new species of the genus Amnestus Dallas, 1851, Amnestus mendeli, is described from the cloud zone of Green Mountain, Ascension Island, and compared with its closest relatives, the Brazilian Amnestus lenkoi Froeschner, 1975 and Amnestus pequinus Froeschner, 1975. It is the first representative of the family Cydnidae recorded on the island thus far. The species is presumed to be an introduction from the Americas, but the hypothesis that it might be endemic to Ascension Island is also not excluded.
New insight into the systematic position of the endemic Madagascan genus Amberiana (Hemiptera: Heteroptera: Dinidoridae) using 12S rDNA sequences
2015
The systematic position of the endemic Madagascan genus Amberiana Dist. İs studied using DNA sequences (the mitochondrial 12S rDNA subunit) for the first time. The phylogenetic relationships within the superfamily Pentatomoidea were computed using neighbor-joining, maximum parsimony, minimum evolution, and maximum likelihood methods, as well as Bayesian estimation. All results based on the mtDNA analyses stand in contrast with previous morphological data. The mtDNA analysis showed close relationships of the genus Amberiana to the genus Sehirus (Cydnidae: Sehirinae) and to species of the family Parastrachiidae, whereas the morphology indicated that the genus was a typical representative of t…
Pullneyocoris dentatus gen. et sp. nov. (Hemiptera: Pentatomoidea: Cydnidae), the third representative of the subfamily Amnestinae from mid-Cretaceou…
2020
Abstract A new genus and species of burrower bug, Pullneyocoris dentatus gen. et sp. nov. (Hemiptera: Cydnidae: Amnestinae), is described from amber of northern Myanmar. It is the third representative of this family known from Burmese amber, and besides its autapomorphies, it presents a mixture of characters relevant to the extant Parachilocoris Horvath, 1919 and Pullneya Horvath, 1919. A comparison of this new genus to the two genera already described from the burmite, i.e. Chilamnestocoris Lis J.A., Lis. B. & Heiss, 2018, and Punctacorona Wang, Du, Yao & Ren, 2019 is also provided.
Tibial combs in the Cydnidae (Hemiptera: Heteroptera) and their functional, taxonomic and phylogenetic significance
2005
Tibial combs in representatives of the family Cydnidae are described in detail for the first time. The structure was studied in 98 species of 58 genera representing all the subfamilies, among them 16 species were investigated using scanning electron microscopic (SEM) techniques. In addition, Parastrachia japonensis (Scott, 1880) of the family Parastrachiidae, and two species of Dismegistus Amyot and Serville, 1843 (a genus of uncertain systematic position within Pentatomoidea) have also been studied. Morphological terminology is proposed for all the structures connected with tibial combs and the term ‘the tibial comb complex’ is suggested; its functional, taxonomic and phylogenetic signific…
