2598EFE2DEC35F6EB006C21ED74C9A56.taxon	diagnosis	Diagnosis. Morphologically, fully winged female individuals of C. breviclava are most similar to those of the Palaearctic species C. detritus Bakkendorf, the type series of which was collected from soil in Chancy, Geneva, Switzerland (Bakkendorf 1964). Its lectotype female (Fig. 6) was designated by Triapitsyn et al. (2013) from one of the two macropterous original syntypes. In macropterous C. breviclava, the female antennal clava (Fig. 2 a) is consistently relatively shorter than that in fully winged C. detritus (Fig. 6), in which it is approximately the same length as combined length of F 3 - F 6 according to the redescription in Triapitsyn (2014), being slightly shorter than the combined length of F 4 - F 6 (but about as long as F 4 - F 6 in the smaller, brachypterous female of C. breviclava). The body of C. breviclava is notably longer (0.6 - 0.76 mm in macropterous, slide-mounted females) than that of macropterous females of C. detritus (0.45 mm according to Bakkendorf 1964), and the gaster is markedly longer (compare Figs 1 a, 2 c and Fig. 6 b, respectively), which is common in fungus dwelling species of the genus. Combined with notably shorter setae on the fore wing venation in C. breviclava (Fig. 1 b), and a different habitat (fungus versus soil for C. detritus), this strongly supports that these two species are clearly distinct despite having some morphological similarities in proportions of female funicular segments and fore wing chaetotaxy. A key to both sexes of the European species of Cleruchus, which is based on that of the Palaearctic species in Triapitsyn (2014), is provided below to further facilitate their recognition.	en	Triapitsyn, Serguei V., Coray, Armin, Rugman-Jones, Paul F.
