The saturella group Externally, species are characterized by the dark brown fascia of the forewing (Fig. 1); creamish white or yellowish cream to ochreous yellow frontal tuft. In the male genitalia, the uncus is comprised of two short, rounded lateral lobes; the gnathos is uniquely-shaped, pointed apically and with a slender, hook-like projection basally; the vinculum is without a juxta, and heavily folded medially (Fig. 1). In the female genitalia, apophyses are long; anal papillae are unique, modified into a single, wide, short transverse lobe with a distinctive, trianglular process (Fig. 1); signum is strongly developed (P. javae and P. amphivittata) or weakly developed (P. saturella). From other groups of the Oriental (or Neotropical) Pseudopostega, the saturella group is distinguished by the unique shape of the gnathos in the male genitalia and anal papillae with a distinctive, triangular process in the female genitalia. Distribution. Currently the group is comprised of three species distributed in Thailand and Indonesia.
