Figures

Fig. 2. A selection of European species of Chordeumatida C.L. Koch, 1847, various families. A. Halleinosoma noricum Verhoeff, 1913 (Trachygonidae Cook, 1896). B. Syngonopodium aceris Verhoeff, 1913 (Attemsiidae Verhoeff, 1899). C. Xylophageuma zschokkei Bigler, 1912 (Haaseidae Attems, 1899), in copula. D. Haplogona oculodistincta (Verhoeff, 1893) (Verhoeffiidae Verhoeff, 1899), in copula. E. Haasea fonticulorum (Verhoeff, 1910) (Haaseidae), in copula. Jörg Spelda has pointed out that on Figs 2C and 2E, both showing copulation in species of Haaseidae, the female is seen to be partially covered in a fine web (most evident in Fig. 2E), probably produced by the male’s spinning glands and perhaps serving to ‘strap down’ the female to the ground.
