Calliopum elisae

Egg. Length 0.68–0.72 mm. Chorion slightly differentiated in dorsal and ventral part. Dorsal side is perforated and with simple ridges, no folding of chorion occurs ( Figs 38–40 ).

First instar larva ( Figs 49–50 ). Length 1.0– 1.86 mm. Length of cephaloskeleton 0.18–0.21 mm. Second larval instar ( Figs 63, 64 ). Length 1.80–3.50 mm. Length of cephaloskeleton 0.30–0.36 mm. Third larval instar ( Figs 77 , 90–95 ). Length 3.46–4.83 mm. Anterior spiracle with 9 papillae ( Fig. 78 ). Integument of abdominal segments and anal division completely villous, even from ventral side. Length of cephaloskeleton 0.55–0.59 mm. Position of mouth hooks approximate to L. cylindricornis (tips of mouth hook slightly diverge). No puparium was acquired.
