Loyugesa (after Grimaldi & Blagoderov, 2001)
Very closely related to Seguyola by the holoptic eyes in males; flagellomeres reduced from 14 to 12, moniliform; median ocellus lost; broadly rounded wing tip; mid tibia with only 1 apical spur; scutum dome-shaped; apical half of hind tibia and entire hind basitarsus inflated; G tIX without a tuft of spicule-like setae at apex (spicules are sparse); gonostyli stout (W:L = 2.2-2.4). Plesiomorphic with respect to Seguyola by having all eye facets equal in size; the wings without maculation; possession of a proboscis (albeit small, only slightly longer than length of head), and several other features. Autapomorphically uniform greyish-brown over entire body, without banding patterns on legs or tergites; scutum with setulae in 3 rows, not scattered; fore tibia without an apical spur; and laterotergite bare.
