Notioseus Park, 2018

Park, Kyu-Tek, 2018, Three new genera and ten new species of the subfamily Lecithocerinae (Lepidoptera, Lecithoceridae) from Cameroon, Africa, based on material collected in 1913 - 18, Zootaxa 4415 (3), pp. 561-579 : 570-571

Genus Notioseus Park , gen. nov.

Type species: Notioseus cupripennis Park , sp. nov. TL: Cameroon.

Diagnosis. Notioseus Park seems to be related to Lecithocera Herrich-Shäffer. The labial palpus is similar to that of Eridichtha Meyrick (type species E. paralocha Meyrick from India), with long, dense hairs dorsally, and the forewing venation is similar to that of Eurodachtha Gozmány (type species: Lecithocera pallicornella Staudinger from Spain), with R3 free and CuA1 free from CuA2, but the hindwing venation differs with a very unusual venation: M2 absent, and M3 and CuA1 coincident, which differs from that of any known related genus. The male genitalia are also similar to those of Eurodachtha in having a ring-shaped plate near basal lobes of the uncus, which formerly was considered unique to Eurodachtha . This combination of characters of the labial palpus, male genitalia, and wing venation is not found in other known genera of the subfamily, hence, a new genus Notioseus Park is proposed herein.

Description for venation. Forewing with R1 arising from before middle, distance between origin of R1 and R2 more than twice that between R2 and R3; R3 free, close to stalk of R4+5 at base; R4 and R5 stalked in basal half; R5 to termen; M2 present; M3 from between M2 and CuA1; CuA1 free; CuA2 arising from near lower corner of cell. Hindwing with M2 absent; M3 and CuA1 coincident ( Fig. 25 ).

Etymology. The generic name is derived from the Greek, notios (= southern) + seos (= moth), and the gender is masculine.
