frontal process
Pair of unique sensory structures of unknown function on the head of remipedes [Brusca and Brusca, 2002].
(Order Isopoda):
The lower region of the epistomal plate or sclerite, in which some Valvifera projects outward to become visible in the dorsal aspect as a protuberance lying above the frontal lamina [Wetzer et al. 1997].
(Class Remipedia):
One of two anteriorly projecting processes on underside of head (cephalon) near base of antennules; relatively small, each consisting of main shaft bearing stout spine. (club-like, "jointed," rod-like). (Syn. frontal filament, preantennular process) [Stachowitsch, 1992].
