Type : deposited in NMW (examined). Allotria ( Allotria ) tscheki – Dalla Torre & Kieffer 1902: 41 . Charips ( Charips ) tscheki – Dalla Torre & Kieffer 1910: 285 . Charips tscheki – Dunn 1949: 106 . Alloxysta tscheki – Hellén 1963: 18 . Diagnosis Alloxysta tscheki is morphologically very similar to A. consobrina and it is practically impossible to differentiate them under the microscope (see comments).

Ferrer-Suay 2013] ( NMW ). Distribution Palaearctic. Certain records: Austria ( Giraud 1860: 128 ), Iran ( Ferrer-Suay et al. 2013a: 39 ), Romania (Feraru et al. 2005: 67), Japan ( Ferrer-Suay et al. 2013i ). Uncertain records: Austria ( Giraud 1860: 128 ; Hellén 1963: 19 ), Belgium ( Lameere 1907 ), England ( Cameron 1889: 54 ), Finland ( Hellén 1963: 19 ), France ( De Gaulle 1908: 26 ; Dalla Torre & Kieffer 1910: 285 ), Germany ( Taschenberg 1866: 129 ; van Veen et al. 2003: 450 ), Hungary ( Dalla Torre & Kieffer 1910: 285 ), Scotland ( Cameron 1886: 85 ), Western Europe ( Andrews 1978: 91 ). Comments The morphological features of A. tscheki are very similar, if not identical, to those of A. consobrina . According to Van Veen et al. (2003) , who treated A. consobrina as A. fuscicornis , these two species have to be considered as biologically different, because their typical hosts are different: A. consobrina tends to attack Brevicorine brassicae (L., 1758) through Diaretiella rapae (M’cIntosh, 1855), while A. tscheki appears in Cryptomizus sp. through Aphidius ribes Haliday, 1834 . Additionally, taking into account the sequences of the ITS2 gene, these two species have different haplotypes. However, these arguments can be disputed. Firstly, Alloxysta consobrina is a cosmopolitan species that has already been found in a diverse range of hosts, although not yet in Aphidius ribes . Secondly, the molecular results are not conclusive due to the low number of specimens analyzed. Also, Van Veen et al. (2003) only took into account specimens collected in a reduced area and studied just five specimens of A. tscheki . For these reasons, we consider that intraspecific variability has not been studied thoroughly enough and that a complete study should be done in order to clarify the status of these two species. While awaiting a more comprehensive assessment, we treat these two species as separate ( Ferrer-Suay et al. 2015b: 33 ).
