Diagnosis. The larvae of A. femina femina can be distinguished from known species based on the following combination of characteristics: 1) occiput with a few dark spots on the dorsal view (Fig. 62); 2) pronotum with protrusion on the posterolateral view, forming a triangular shape (Fig. 64); 3) margin of compound eyes with a row of few spiniform setae on the ventral view (Fig. 66) and 4) abdominal S3–S4 covered with short simple setae (Fig. 68).
