Genus Lacuniola Park, 2012

Lacuniola Park was established as monotypic based on the type species Lacuniola hadrorhacha Park, 2012 from Papua New Guinea, and is a close relative of Pectinimura Park. The genus is characterized by having characteristically modified antennae, with a unique elliptical swelling forming an open concavity near the base of the flagellum (Fig. 31a) in the male, and broadly thickened with rough scales in the basal part of the flagellum in the female. The hindwing of the male has some longitudinal brown androconial scales scattered centrally between M1 and CuA2 from base. The male genitalia have comb-like bristles in the valva, which is similar to that of Pectinimura Park. The wing venation is similar to that of Lecithocera, but R3 of the forewing is free. The following new species exhibits sexual dimorphism in the shape of the antenna (Figs. 32a, 32b) and the hindwing.
