On the terminology of the genitalia structures of lichen moths (Lepidoptera: Erebidae: Arctiinae: Lithosiini) with some references to Noctuidae

Abstract

The present paper briefly describes the Lithosiini genitalia and discusses their terminology. Twelve new terms are introduced: medius, introrsum, conjuga, collis, iuba, jugum basalis, jugum distalis, arcus, intersaccular bridge, lamella centralis, clasper region, and elasma for the male genitalia, and diverticulum bursae for the female genitalia. The terminological inconsistencies in Noctuidae are discussed with reference to the original concept by the various authors who introduced the terms, and the approaches by authors sensu auct. are also considered. In cases of discrepancies the terms preferable are suggested. Fully annotated figures are provided for the structures discussed.

“…The wing markings terminology partly follows de Vos & Suhartawan (2011) while that of genitalia partly follows Volynkin (2024). 4) but can easily be distinguished by the somewhat broader forewing with a less elongate apex, the intense pink suffusion on the both wings, the shorter subbasal costal spot, the narrower antemedial and broader postmedial lines, and the well-developed postmedial fascia on the hindwing.…”

“…Different labels are separated by a slash ("/") while the different lines of the same label are separated by an upright slash ("|"). Any additional data are provided in square brackets.The male and female genitalia terminology followsVolynkin (2024).…”
