† Ectenobythus Engel et al., 2013

The genus was described from inclusions in Albian Spanish amber, with a single included species, † Ectenobythus iberiensis . Based on figure 1 of Engel et al. (2013), we can state that the holotype and paratype belong to distinct clades. The holotype has a long scape, fusiform profemur, long pronotum (hiding the propleura in dorsal view), short propodeum (judging from the relative position of the meso- and metacoxae), posterior portion of metasoma abruptly narrowed and protruding. These characters, together with the reduced forewing venation, indicate that this genus can unequivocally be placed in Chrysididae .
