Deinodryinus veltenisp. n. is described from middle Eocene Baltic amber. The species differs from other fossil Palaearctic species of Deinodryinus Perkins owing to the shape of the antenna (clavate, with distal part very thickened), the large compound eyes, and the distal part of the stigmal vein much longer than the proximal part. A revision and a key to the fossil Palaearctic species of Deino...

Corononcodes ziegleri spec. nov. is described and illustrated based on material from Iran. The species represents the second Palaearctic representative of this panopine genus. In addition, C. siculus Bezzi is recorded from Fuerteventura (Canary Islands, Spain) for the first time. An identification key to the Palaearctic species of Corononcodes is presented. Additional faunistic records for the ...

The Palaearctic species of the S. exarator species group of the genus Spathius Nees with entirely sculptured mesopleuron are discussed. Four new species, Spathius austriacus sp. nov., S. intercontinentalis sp. nov., S. pseudodentatus sp. nov., and S. sculptipleurum sp. nov., are described and illustrated. Spathius curvicaudis Ratzeburg, 1944 treated here as junior synonym of S. erythrocephalus ...

Hofferia and Stenoheriades are closely related, species-poor genera of the osmiine bees (Megachilidae). Analysis of female pollen loads and field observations indicate that species of both genera have a strong affinity to Asteraceae as pollen hosts. Both genera use insect burrows in dead wood as nesting site, and Hofferia schmiedeknechti was found to build cell walls and nest plug with resin pa...

Lampromyia bellasiciliae sp. n. is described from Sicily, Italy. The new species belongs to the pallida subgroup and is differentiated from related taxa in a dichotomous identification key. DNA barcodes for eight of the currently recognised ten Palaearctic species of Lampromyia are provided, and the calculated genetic distances between the taxa and species groups/subgroups are discussed. New di...

We provide a general overview of features and technical specifications of an original interactive key web application for the identification of Palaearctic Tachinidae genera. The full list of terminal taxa included in the key, which is the most updated list of genera currently recorded for the Palaearctic Region, is given. We also briefly discuss the need for dealing with detailed and standardi...

Present state of the knowledge of the Palaearctic Microchelonus species: 1) In Tobias (2010) monographed 434 Microchelonus species occuring in the Palaearctic Region of which Tobias alone has described 379 new species during the last five decades. 2) His monographic survey essentially promoted the identification of the Palaearctic species. In the present contribution 86 known Microchelonus spec...

In addition to the three so far known species of Prosopistoma Latreille, 1833 from West Palaearctic region, P. pennigerum (Müller, 1785), P. oronti Alouf, 1977 and P. orhanelicum Dalkıran, 2009, two new species are described based on larvae. Prosopistoma helenae sp. n. has been found in Iraq (Tigris River in Mosul) and Prosopistoma alaini sp. n. in Algeria (Oued Isser, Sidi Abdelli). Critical d...

Four new species of Tanycarpa (Hymenoptera, Braconidae, Alysiinae), T. gymnonotum Yao sp. n., T. similis Yao sp. n., T. areolata Yao sp. n., and T. lineata Yao sp. n., are described from the Palaearctic Region of China, and T. chors Belokobylskij is newly recorded from China. Significant range extensions are given for T. bicolor (Nees von Esenbeck), T. gracilicornis (Nees von Esenbeck), and T. ...

Forty-one species of the ant-like stone beetle genus Eutheia Stephens, 1830 are known, distributed mostly in the Palaearctic (34 species, Taiwan included), and also Nearctic (3 spp.) and Neotropical (4 spp., exclusively Mesoamerican) regions (Jałoszyński 2014). As nearly all Eutheiini, Eutheia is a rare genus and even Central European species are usually represented in large museum collections ...
