Phylogeny of the ophrynopine clade revisited: review of the parasitoid sawfly genera Ophrella Middlekauff, Ophrynopus Konow and Stirocorsia Konow (Hymenoptera : Orussidae)

The rare family Orussidae comprises the only parasitoid sawflies and are sister to the Apocrita, the latter comprising most of Hymenoptera. Because of this, their morphology and relationships have been particularly important for interpreting the morphology of and biological transitions within the order as a whole. Within the Orussidae the ophrynopines are a comparatively diverse clade with a predominantly southern hemisphere distribution. Here, a revised and expanded morphological dataset incorporating several new taxa is used to test ophrynopine relationships and provide further insights into their evolutionary history. The analyses largely corroborate previous results. The distribution pattern and the fossil record indicate that the ophrynopines radiated in the early Cenozoic in the Australasian-Oceanian and the Neotropic regions and later dispersed into the Nearctic, Eastern Palaearctic and Indomalayan regions. The South American genus Ophrella Middlekauff, 1985 is well supported as a monophyletic genus, whereas Ophrynopus Konow, 1897 is paraphyletic with respect to Stirocorsia Konow, 1897. Three new species, Ophrella eldorado Vilhelmsen, sp. nov., Ophrynopus guarani Blank, D.R. Smith & Vilhelmsen, sp. nov., and Ophrynopus rupestris Vilhelmsen, Costa & Alvarenga, sp. nov. are described. Ophrella lingulata Middlekauff, 1985 is treated as a junior synonym of Ophrella amazonica (Westwood, 1874). Stirocorsia is treated as a junior synonym of Ophrynopus. The species Ophrynopus apicalis (Togashi, 2000), Ophrynopus kohli (Konow, 1897), Ophrynopus maculipennis (F. Smith, 1859) and Ophrynopus tosensis (Tosawa & Sugihara, 1934), formerly in Stirocorsia, are transferred to Ophrynopus. Revised keys to the species of Ophrella, Ophrynopus and the genera in the ophrynopine clade are provided. In addition, Orussidae are recorded from Bolivia and French Guiana for the first time.

Cryptic Diversity in Mongolian Vespertilionid Bats (Vespertilionidae, Chiroptera, Mammalia). Results of the Mongolian-German Biological Expeditions Since 1962, No. 299

In contrast to the Eastern Palaearctic region a high degree of cryptic diversity was discovered among temperate bats of the Western Palaearctic region in the last ten years. Climatic oscillations caused severe changes in the distribution of species throughout the Palaearctic region during the Pleistocene. Exploring multiple taxa can help to understand general evolutionary differentiation processes. In the present study genetic variation within and among 94 Mongolian vespertilionid bats of six genera (Hypsugo, Eptesicus, Vespertilio, Myotis, Plecotus, and Nyctalus) was screened by sequencing a 798 bp fragment of the mitochondrial ND1 gene and then subsequently compared with those of Western Palaearctic taxa. This allowed first insights in the differentiation among a wide range of bats across the Palaearctic region. A total of 16 distinct mitochondrial lineages were found in Mongolia. Thirteen lineages differed by at least five percent sequence divergence from Western Palaearctic species. Only three lineages (Eptesicus nilssonii, Vespertilio murinus, and Nyctalus noctula) showed lower divergence values. Our data demonstrate a substantial differentiation between most Western and Eastern Palaearctic vespertilionid bats. Estimations of divergence times showed that most divergence appeared prior to the Pleistocene, but current distributions of bats were most likely shaped by the usage of multiple refugia during glaciations.

Revision of the Holarctic species of Dilyta Förster (Hymenoptera: Figitidae: Charipinae) with descriptions of four new species from the eastern Palaearctic

The genus Dilyta, and the known species of this genus present in the Holarctic, D. subclavata Förster from Europe and D. rathmanae Menke and Evenhuis from USA, are redescribed. Four new species of Dilyta are described from the eastern Palaearctic region: D. aleevae sp. n. from Kazakhstan, D. japonica sp. n. from Japan, and D. longinqua sp. n. and D. sinica sp. n. from China.

First records of Microptila Ris (Trichoptera: Hydroptilidae) from Japan, with description of a new species

Abstract Microptila orienthula, sp. n. from Japan is described and illustrated based on adults of both sexes. The new species represents the first finding of Microptila in the Eastern Palaearctic Region, and it appears to be more closely related to Oriental species of Microptila than to the two Western Palaearctic species. The finding of a new species with affinities to the Oriental species as far northeast as Japan is noteworthy but fits well with general zoogeographical affinities of the Japanese fauna to the Oriental Region. The type locality indicates a hygropetric habitat for the larva, in agreement with the known larval habitat of the European type species Microptila minutissima Ris, 1897.
