lacinia mobilis

An enlarged, nearly articulated spine of the mandible's spine row that is adjacent to the incisor process. It is found only on the left mandible. On the right mandible, it is replaced by a large spine similar in shape to the more posterior members of the spine row [Wilson, 1989].

Articulated accessory process of the mandible between the molar and incisor process typical of peracarids [Brusca and Brusca, 2002].

Small, generally toothed process articulated with incisor process of mandible [Moore and McCormick, 1969].

The articulated 'cutting ' blade of the mandible. Exhibits varying degrees of development in the Tanaidacea [Holdich and Jones, 1983].

(Order Cumacea):

Small, articulated process between setal row and incisor process on mandible. Fully developed only on left mandible [Stachowitsch, 1992].

(Order Tanaidacea):

Small, articulated process between setal row and incisor process on mandibles. May be present only on left mandible, (present/absent on right mandible) [Stachowitsch, 1992].

(Superorder Peracarida):

Small, generally toothed, process articulated with incisor process of mandible [McLaughlin, 1980].

(Order Amphipoda):

Small, articulated accessory process between setal row and incisor process on each mandible. Differs in shape on left and right mandibles. (serrate, smooth) [Stachowitsch, 1992].

(Order Isopoda):

Small, usually toothed, process articulating at base of incisor in left or both mandibles [Kensley and Schotte, 1989].

(Order Isopoda):

Small, usually toothed, process articulating at base of incisor of left or both mandibles; present in most isopod groups [Wetzer et al. 1997].

(Order Isopoda):

Toothed, movably articulated process between setal row and incisor process on left (and occasionally also on right) mandible [Stachowitsch, 1992].

(Order Mysida):

Articulated process between pars centralis (setal row) and incisor process on left mandible; frequently absent on right mandible [Stachowitsch, 1992].

(Class Remipedia):

Movable, toothed process between molar and incisor processes at tip of each mandible. Laciniae mobili of left and right are asymmetrical, i.e., of different shape and/or denticle number. (margin: concave and sickle-like, with three or six denticles) [Stachowitsch, 1992].

(Order Thermosbaenacea):

Articulated process between lifting spines and incisor process on each mandible [Stachowitsch, 1992].
