Subgenus LOPHODACUS Collart

Dacus (Lophodacus) Collart, 1935: 8 . Type species, Dacus hamatus Bezzi, 1917, by monotypy. Other synonyms: White (2006: 114)

All species included within sg. Lophodacus by White (2006), with the exception of D. umehi White, 2006, lacked a complete covering of microtrichia across the narrow raised subbasal section of cell br. The new discovery of males of the Seguyi group, previously placed in sg. Didacus, indicates that these species have enlarged costagial setae, in common with some groups of sg. Lophodacus, notably the Brevis group; the Seguyi group also have microtrichia across the entire depth of cell br.
