Comments: Neosextius is related to Sextius (Day 1999) with which it shares features such as reticulate venation and pale greenish colouring (both genera have species with brown markings on legs and tegmina). However, in Sextius the lateral pronotal processes extend laterally as triangular horns while in Neosextius they are swept forward and closely apposed to form an apparent single anteriorly directed process.
