Characterisation of the genus.

The species belonging to Neoliparina have largely characteristic external morphology demonstrated by the very feathery bipectinate-fasciculate antenna and the short and broad forewing with orange-red ground colour in males, ornamented with diffuse greyish transverse lines and a dark, rounded discal spot. Sexual dimorphism is prominent in this genus, the females being ca. 1.5 times larger, with shorter, less feathery antenna, more elongate forewings, a darker, generally more ochreous ground colour and reduced markings, whilst retaining the contrasting discal spot. Male genitalia are characterised by a broad-based, truncate uncus, ribbon-like arms of the tegumen, valvae, which are broad at the base and gradually tapered towards their apex, a thick U- or V-shaped juxta, a short triangular vinculum, a short phallus without a carinal process and a short proximally inflated vesica, bearing a small rugose sclerotised area. The female genitalia are characterised by the short, broad, rounded papillae anales, triangular pseudopapillae, the medium-long posterior apophyses and similarly long anterior apophyses, and the broad, rounded quadrangular antevaginal plate. The ostium bursae is wide with a heavily sclerotised margin, the distal end of the ductus bursae forming a heavily sclerotised antrum, the shape of which is a specific character. The proximal section of the ductus bursae is thick and membranous, the corpus bursae is large, ovoid, bearing two equally sized membranous appendices and may have a sclerotised signum.
