Seems to match Seitz's not particularly detailed description except for size:

C. entella Druce. Head and collar are metallic blue, antennae black. Collar, thorax and abdomen above bright-red, the 3 last abdominal rings black; 
dorsal and lateral spots metallic blue. Ventral side black, on the 2nd and 3rd rings white. The forewings have a red basal part, veins, margins and a
pex are black; also the hyaline hindwings are bordered with black. Expanse of wings: 45 mm. Ecuador.
Also seems to be almost dentical with BOLD BC ZSM Lep 32417

AZ NOTE: Cat. Lep. Ph. Brit. Mus. uses a non-standard definition of "tegulae" and "patagia".
From Vol. 1:
"The thorax consists of three segments-the prothorax, bearing the
tegulm or collar-lappets, the patagia or shoulder-lappets, and the
fore legs ..."
