Frontal view, showing jaws and anal opening, which I think is Y-shaped, or maybe T-shaped. It does appear to be surrounded by two fleshy lobes. See Scarabaeoid Indentification Guide: Lucanidae--By Brett C. Ratcliffe and M.J. Paulsen. Excerpts quoted below:

Larvae. Form scarabaeiform (c-shaped, subcylindrical). Color creamy-white or yellowish (except at caudal end which may be darkened by accumulated feces). Cranium heavily sclerotized, lightly pigmented. Antennae 3-4 segmented, last segment greatly reduced in size....Anal opening Y-shaped or longitudinal, surrounded by 2 fleshy lobes. Legs 4-segmented. Stridulatory apparatus on meso- and metathoracic legs present; claws present.
