Rainieria antennaepes and the southern Calobatina geometra, which both look similar. They can be distinguished from photos as follows (Chris Angell):
Eyes: Taeniaptera sp. - maroon & striped; Rainieria antennaepes - bright red, unstriped; Calobatina geometra - dark, unstriped
Body shape: Taeniaptera sp. - less slender; Rainieria antennaepes - more slender; Calobatina geometra - more slender
Wing pattern: Taeniaptera sp. - a circular, bulls-eye like pattern; Rainieria antennaepes - a triangular dark spot; Calobatina geometra - usually unmarked, sometimes like R. antennaepes
Forelegs: Taeniaptera trivittata - first tarsomere dark, remaining tarsomeres light (apical tarsomere dark in the rare southern Taeniaptera lasciva); Rainieria antennaepes - first tarsomere white, sometimes with apical tarsomere dark; Calobatina geometra - first tarsomere white, last 2-3 tarsomeres dark
