The systematics and bionomics of the Palaearctic brood parasitic genus Nipponodipogon Ishikawa, 1965 are revised. Seven species are listed. A new species N. sudai Shimizu, sp. nov. (Japan, Honshu) and the hitherto unknown males of N. iwatai (Ishikawa, 1965) and N. nagasei (Ishikawa, 1965) are described and illustrated. Six species from Japan and the Russian Far East are redescribed. A key to sp...

Anarta Ochsenheimer, 1816 is a hadenine genus restricted to Palaearctic and Nearctic Regions. The genus includes about 80 described species and subdivided into seven subgenera (Hacker 1998; Fibiger et al. 2011): Trichoclea Grote, 1883 (= Hadula Staudinger, 1889), Cardiestra Boursin, 1963, Ptochicestra Hacker, 1998, Aglossestra Hampson, 1905, Calocestra Beck, 1991, Pulchrohadula Hacker, 1998 and...

Two new species, Lasiopa aksarayiensis sp. n. and Lasiopa aktasii sp. n. are described from the Central Anatolian stepe in Turkey. All diagnostic characters are illustrated and possible relationships of both taxa are briefly discussed. The first record of Lasiopa pseudovillosa (Rozkošný, 1983) from Turkey is presented and additional Turkish localities of Lasiopa caucasica (Pleske, 1901) are rec...

A new genus and species of Schizogyniidae (Acari: Mesostigmata: Celaenopsoidea), Euroschizogynium calvum gen. nov. and sp. nov., associated with Scarites terricola Bonelli, 1813 (Coleoptera: Carabidae) is described from Ukraine, representing the first record of the family from the Palaearctic. Fusura civica Valle & Fox, 1966 is moved out of the Schizogyniidae and placed into the Megacelaenopsid...

This paper reports on three species of mites of the genus Myrmozercon Berlese, 1902 associated with ants in Iran--Myrmozercon crinitus Joharchi sp. nov. from Pheidole pallidula (Nylander), Myrmozercon michaeli Joharchi sp. nov. from Messor sp. and Myrmozercon tauricus Trach & Khaustov from Crematogaster schmidti (Mayr) in the bark of grape vines. Myrmozercon is redefined, the distribution, and ...

The oviposition behaviour of four ant parasitoids was observed and filmed for the first time. The movies are available from YouTube (search for Elasmosoma, Hybrizon, Kollasmosoma and Neoneurus). Two of the observed species (Neoneurus vesculussp. n. and Kollasmosoma sentumsp. n.) are new to science. A third species (Neoneurus recticalcarsp. n.) is described from Slovakia and Norway. Keys to the ...

Seven species of Orsunius Assing, 2011 are described and illustrated, six them from Borneo one Vietnam: weigeli spec. nov. (North Vietnam), O. floreni (Malaysia: Sabah), flavoniger incitatus curvicollis tricolor arboris Sabah). The genus now includes 31 named extant distributed in the southern East Palaearctic, Oriental, northern Australian regions.

Two species of Dolichomitus Smith, 1877 emerged from the trunks Juglans mandshurica Maxim. in Kuandian and Benxi Manzu Autonomous Counties, Liaoning, Palaearctic part China. One new species, D. juglanse Sheng #38; Li sp. nov., reared Menesia flavotecta Heyden, 1886 Mesosa myops (Dalman, 1817) (Cerambycidae), is described illustrated. A key to known China provided.

Setihercostomus Zhang et Yang, 2005 is separated from the genus Hercostomus Loew, 1857, by the following combination of characters: clypeus short and narrow, not reaching lower margin of eyes, bearing one pair of strong bristles in both sexes; pteropleuron (= anepimeron) with group of fine hairs in front of posterior spiracle; male cercus large and thick, nearly as long as epandrium (Zhang & Ya...

In recent years we have investigated the evolution of the Holarctic leaf-beetle genus Timarcha using molecular approaches, but to date several important questions remained unanswered, including its systematic arrangement in a temporal context, or the phylogenetic placement of the Nearctic taxa. Here I present a reanalysis of available genetic data together with newly generated data for key taxa...
