Tachysphex austriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.

ABSTRACT: Tachysphex pompiliformis (Panzer, 1804) and Tachysphex austriacus Kohl, 1892 species subgroups belong to the Tachysphex pompiliformis species group, and both subgroups consist of morphologically similar species. The Tachysphex austriacus Kohl species subgroup comprises four species in Europe and Turkey. For this subgroup, differential diagnoses of Tachysphex austriacus and Tachysphex prismaticus Straka, 2005 are presented, and Tachysphex hungaricus sp. n. from Hungary and Tachysphex smissenae sp. n. from Spain, France and Turkey are described. The Tachysphex pompiliformis species subgroup consists of ten species from Europe and Turkey. For this subgroup, differential diagnoses of Tachysphex ferrugineus Pulawski, 1967 and Tachysphex opacus F. Morawitz, 1893, as well as the differential diagnosis and redescription of Tachysphex pompiliformis, are presented. Tachysphex dimidiatus (Panzer, 1809), Tachysphex jokischianus (Panzer, 1809) and Tachysphex nigripennis (Spinola, 1808) are resurrected from synonymy with Tachysphex pompiliformis and redescribed. Neotypes of Tachysphex dimidiatus (Panzer) and Tachysphex nigripennis (Spinola) are designed. Tachysphex bohemicus sp. n. from the Czech Republic; Tachysphex cretensis sp. n. from Crete, Greece; Tachysphex nobilis sp. n. from Bulgaria, the Czech Republic, Hungary, Poland, Slovakia and Turkey; and Tachysphex punctipleuris sp. n. from Bulgaria, Germany, Hungary, Italy, Slovenia and Turkey are described. Identification keys to all species from Tachysphex pompiliformis and Tachysphex austriacus species subgroups known from Europe and Turkey are presented.

Project description:The genus Gasteruption Latreille, 1796 (Hymenoptera: Evanioidea: Gasteruptiidae: Gasteruptiinae) from North Iran and Turkey is revised, keyed and fully illustrated for the first time. In total 36 species are treated of which 33 are recorded from Turkey and 23 from Iran. Fifteen species are new for science: Gasteruptionaciculatum van Achterberg, sp. n., Gasteruptionagrenum van Achterberg, sp. n., Gasteruptionbrevibasale van Achterberg & Saure, sp. n., Gasteruptioncoriacoxale van Achterberg, sp. n., Gasteruptionflavimarginatum van Achterberg, sp. n., Gasteruptionheminitidum van Achterberg, sp. n., Gasteruptionhenseni van Achterberg, sp. n., Gasteruptionischnolaimum van Achterberg, sp. n., Gasteruptionnigrapiculatum van Achterberg, sp. n., Gasteruptionpaglianoi van Achterberg & Saure, sp. n., Gasteruptionpseudolaticeps van Achterberg, sp. n., Gasteruptionpunctifrons van Achterberg, sp. n., Gasteruptionschmideggeri van Achterberg & Saure, sp. n., Gasteruptionscorteum van Achterberg, sp. n. and Gasteruptionsmitorum van Achterberg, sp. n. Twenty-one species are reported new for Turkey and 16 species new for Iran. Fifteen new synonyms are proposed: Foenusterrestris Tournier, 1877, Gasteruptiontrifossulatum Kieffer, 1904, and Gasteruptionignoratum Kieffer, 1912, of Gasteruptioncaucasicum (Guérin-Méneville, 1844); Gasteruptiondaisyi Alekseev, 1993, of Gasteruptiondolichoderum Schletterer, 1889; Gasteruptionassectatorvar.nitidulum Schletterer, 1885, of Gasteruptionfreyi (Tournier, 1877); Gasteruptionschossmannae Madl, 1987, of Gasteruptionhastator (Fabricius, 1804); Gasteryptionfallaciosum Semenov, 1892, Gasteruptiondubiosum Semenov, 1892 and Gasteruptionobsoletum Semenov, 1892, of Gasteruptioninsidiosum Semenov, 1892; Gasteryptionschewyrewi Semenov, 1892, of Gasteruptionjaculator (Linnaeus, 1758); Gasteruptionfloreum Szépligeti, 1903, of Gasteruptionlugubre Schletterer, 1889; Gasteruptiontrichotomma Kieffer, 1904, and Gasteruptionpalaestinum Pic, 1916, of Gasteruptionmerceti Kieffer, 1904; Gasteryptionfoveiceps Semenov, 1892, of Gasteruptionnigrescens Schletterer, 1885, and Gasteruptionlibanense Pic, 1916, of Gasteruptionsyriacum Szépligeti, 1903. Gasteruptionlugubre Schletterer, 1889, is recognised as a valid species. Lectotypes are designated for Ichneumonassectator Linnaeus, 1758; Ichneumonjaculator Linnaeus, 1758; Foenusterrestris Tournier, 1877; Foenusfreyi Tournier, 1877; Foenusnigripes Tournier, 1877; Foenusgoberti Tournier, 1877; Foenusgranulithorax Tournier, 1877; Foenusminutus Tournier, 1877; Foenusborealis Thomson, 1883; Faenusdiversipes Abeille de Perrin, 1879; Foenusrugulosus Abeille de Perrin, 1879; Faenusobliteratus Abeille de Perrin, 1879; Faenusundulatum Abeille de Perrin, 1879; Faenusvariolosus Abeille de Perrin, 1879; Gasteruptiondistinguendum Schletterer, 1885; Gasteruptionlaeviceps Schletterer, 1885; Gasteruptionthomsonii Schletterer, 1885; Gasteruptionfoveolatum Schletterer, 1889; Gasteruptionsowae Schletterer, 1901; Gasteruptionfoveolum Szépligeti, 1903; Gasteruptionfloreum Szépligeti, 1903; Gasteruptioncaudatum Szépligeti, 1903; Gasteruptionsyriacum Szépligeti, 1903; Gasteruptionmerceti Kieffer, 1904 and Gasteruptionignoratum Kieffer, 1912.

Project description:Trachusa pubescens (Morawitz, 1872) s. l. has a distribution extending from south-eastern Europe over Anatolia and the Caucasus to Iran and Turkmenistan, and was formerly regarded as a species with high intraspecific variation. By means of an examination of 208 specimens from all parts of the distribution area, covering structural features of the head (mandibles, clypeus), the apical terga and the genitalia, the colouration pattern as well as a morphometric analysis of 26 body measurements with multivariate statistical methods (Principal Component Analysis, Discriminant Analysis), it was possible to assign the material to five species of which two are new to science (Trachusa balcanicasp. n. and T. hakkariensissp. n.). Two taxa which had previously been described as "variations" or subspecies are elevated to species rank: T. verhoeffi (Mavromoustakis, 1955), stat. n. and T. maxima (Friese, 1931), stat. n. Additionally, some populations can be distinguished by their colouration pattern or by subtle differences in size or body shape, but these features are apparently of no taxonomic significance at the species level. Trachusa balcanica sp. n. and T. verhoeffi have distribution areas which do not overlap with any of the other members of the species group and can thus be characterised as allospecies. By contrast, the distribution areas of the other three species, T. pubescens, T. maxima and T. hakkariensis sp. n., overlap to a certain extent and they co-exist at least to some degree in sympatry. While they have been found in the same region, they have so far never been found together at exactly the same location and it is suggested that species divergence occurred in parallel with ecological differentiation. Niche partitioning such as flower preferences is a mechanism which may be invoked to explain this. Some specimens with intermediate characters were found, particularly in contact zones, and it is thought that some hybridisation may occur. A partly melanistic individual of T. balcanicasp. n. was found, which is probably the first described melanistic individual in the tribe Anthidiini.
