Belongs within: Embiidina.
The Embiidae are a group of webspinners known from Africa and Asia, characterised by males with two-segmented cerci and a more or less straight base to the tenth tergite (Ross 2007). Fossil representatives are known from the Eocene-Oligocene Florissant shale of Colorado and from Eocene Baltic amber (Ross 2000).
Characters (from Ross 2007): Adult males monochromatic brown, alate or apterous, robust, body length averaging 12 mm. Cranium longer than broad, eyes small. Mandibles usually elongate, parallel-sided, distal teeth usually curled ventrad, subapical teeth usually obscured by dorsal. Antennal setae short. Wing vein MA forked. Hind basitarsi short, with one or two median papillae. Terminalia with hemitergites narrowly spaced; medial sclerite inconspicuous; flap-like projection partly extending over epiproct. Cerci two-segmented, basal segment often globose, always echinulated, occasionally bilobed.
