Lecithoceridae (Lepidoptera: Gelechioidea) of New Guinea, Part VIII: A new genus Sulciolus, with descriptions of two new species

Abstract

AbstractAs the eighth part in a series on the family Lecithoceridae (Lepidoptera: Gelechioidea) from New Guinea, Sulciolus Park, gen. nov. of the subfamily Lecithocerinae is described, based on the type species, S. pachystoma (Diakonoff), comb. nov., with two additional new species: (i) S. circulivalvae sp. nov.; and (ii) S. kaindiana sp. nov. The new genus shares with Achroa Meyrick, Onnuria Park, Hamatina Park and Scolizona Park a uniquely specialized 3rd segment of labial palpus, but it is differentiated from them by having a longitudinal furrow on the inner surface of the segment. Sulciolus abrasa (Diakonoff), S. capra (Diakonoff), S. induta (Diakonoff) and S. perspicua (Diakonoff) are newly combined, and Lecithocera sextacta Diakonoff is synonymized with S. perspicua (Diakonoff). Keys to genera related to Lecithocera and to species of the genus are given. Adults, labial palpi, wing venations and male genitalia are illustrated.
