The sinica species-group

Atrovirensis sinica and next five species ( A. owadai, A. taiwani, A. furcatus, A. sp. cf. furcatus and A. sacculatus) represent the sinica species group. The taxa of this group have rather massive uncus, shorter than in atrovirens - group, more rounded and much smaller cucullus, much larger gap between cucullus and saccular lobe of valva, more elongate harpe, much longer medial diverticulum, and the apically double-lobed large cornutus. The female genitalia of the sinica species group could be characterised by relatively small sclerotised ovipositor with slightly lyriform and apically constricted papillae anales, small, shallow antrum, short ductus bursae and elongate corpus bursae.
