Group Seguyi

D. seguyi Munro, 1984 is here placed in sg. Lophodacus following the discovery of a specimen that appears to be a male of D. seguyi . The males of D. seguyi and D. acutus have enlarged costagial setae (new data included in revised key; revised couplet 208), which places them within sg. Lophodacus as defined by White (2006). This feature is shared with the Brevis group, within which Hancock & Drew (2006) placed D. seguyi . However, they have microtrichia across the entire depth (at least basally) of the raised narrow subbasal area of wing cell br, unlike almost all other sg. Lophodacus spp., including the Brevis group.
