Dialectica Walsingham, 1897: 150 View in CoL . Type species: Gracilaria scalariella Zeller, 1850 .

Eutrichocnemis Spuler, 1910: 409 View in CoL . Type species: Gracillaria scalariella Zeller, 1850 .

The genus Dialectica View in CoL , comprising 24 species, is distributed worldwide, with most species known from Sub-Saharan Africa. The morphological characters of the adults, including their genitalia, were outlined by Vári (1961) and Kuznetzov (1979), but the most comprehensive redescription of the genus was provided by Kumata et al. (1988a). Here we used the following characters as diagnostic for Dialectica View in CoL : (1) antennal scape with flap of scales; (2) valva with two long combs on inner surface; (3) caudal margin of the male abdominal segment VII well sclerotized with paired processes or notched; (4) ductus bursae long, often partly shagreened and with a pair of valva-shaped sclerites or protuberances.
