ABSTRACT
A new species, Meschia brevirostris sp. nov. (Hemiptera: Heteroptera: Lygaeoidea: Meschiidae), is described from New Caledonia. Photographs and SEM micrographs of the male and female habitus, genital structures and selected morphological structures are presented.

The genus Dominikon Dobosz, Krivokhatsky & Ábrahám gen. nov. is separated from the genus Nedroledon Navás, 1914, along with two previously described species: Dominikon lagopus (Gerstaecker, 1894) and Dominikon iranensis (Hölzel, 1972) comb. nov. A new species, Dominikon aspoecki Dobosz, Ábrahám & Krivokhatsky sp. nov. is described from Iran and Turkmenistan. The new genus is characterized by the presence of a prominent postventral processus of the ectoproct. The genus Nedroledon includes two valid Western Palaearctic species (Nedroledon anatolicus Navás, 1914 and N. maculatus Zakharenko, 1990). The paper contains a key for both genera, Nedroledon and Dominikon, and a key for the species of the new genus Dominikon. The taxonomic features and habitus of each species are illustrated. New data on the distribution of species of the two related genera Dominikon gen. nov. and Nedroledon Navás, 1914 are also given.

A list of Asian species of Megaloptera deposited in the Upper Silesian Museum which includes 35 species of Corydalidae and four species of Sialidae. A new species of the dobsonfly genus Protohermes van der Weele, 1907, P. stangei sp. nov. from central Vietnam is described. Protohermes weelei Navás, 1925 and Protohermes yangi Liu, Hayashi Yang, 2007 are newly recorded from Laos and Sialis longidens Klingsted, 1932 is newly recorded from North Korea.

Retracing complex population processes that precede extreme bottlenecks may be impossible using data from living individuals. The wisent (Bison bonasus), Europe's largest terrestrial mammal, exemplifies such a population history, having gone extinct in the wild but subsequently restored by captive breeding efforts. Using low coverage genomic data from modern and historical individuals, we investigate population processes occurring before and after this extinction. Analysis of aligned genomes supports the division of wisent into two previously recognized subspecies, but almost half of the genomic alignment contradicts this population history as a result of incomplete lineage sorting and admixture. Admixture between subspecies populations occurred prior to extinction and subsequently during the captive breeding program. Admixture with the Bos cattle lineage is also widespread but results from ancient events rather than recent hybridization with domestics. Our study demonstrates the huge potential of historical genomes for both studying evolutionary histories and for guiding conservation strategies.

First specific records of chironomids of the tribe Tanytarsini from New Caledonia based on detailed descriptions of new species are presented. Cladotanytarsus (Cladotanytarsus) stylifer sp. nov. and its closest relatives, i.a. Cladotanytarsus (C.) isigacedeus (Sasa et Suzuki, 2000), comb. nov., known from males bearing extraordinarily elongate hypopygial anal points are diagnosed. Paratanytarsus mirificus sp. nov. is described as adult male with unique structure of its hypopygium and shortened antennae. Diagnostic description of Tanytarsus fuscithorax Skuse, 1889 is also complemented.

Ochetostethomorpha secunda sp. nov. from Namibia, the second species of the South African endemic genus is described, illustrated, and compared with O. nollothensis Schumacher, 1913. The new species is the third of the subfamily Sehirinae known from Namibia. Moreover, a DNA barcode sequence was generated for this new species (827 bp of cytochrome oxidase I) and was deposited in GenBank.

A poorly known species of antlions, Omoleon jeanneli Navás, 1936 is redescribed and illustrated with five photos and genitalia drawings. A key for African Dendroleontini is given. This is the first record of O. jeanneli from Kenya.
