Fore leg as in Fig. 258. Male flagellum 11-segmented, the two apical segments broadly joined ( Fig. 257) and genitalia distinctively complex and asymmetrical ( Fig. 259).

Body length. 347–881 (1536?) µm.

Distribution. Worldwide, except Afrotropical.

Hosts. Cicadellidae , gall-forming Eulophidae .
