incisor process
Biting portion of gnathal lobe of mandible. (Syn. pars incisiva) [McLaughlin, 1980].
Biting portion of gnathal lobe of mandible. (Syn. pars incisiva) [Moore and McCormick, 1969].
Cutting process on mandible; widely separated from molar or grinding process in some shrimps, e.g., Pandalidae, in close proximity in others, e.g., Oplophoridae [Butler, T.H.].
Cutting process, often toothed or cusped, of the mandible [Perez Farfante and Kensley, 1997].
Cutting surface (lobe) of mandible (as opposed to molar or grinding lobe) (see Fig. 23h) [Hobbs and Jass, 1988].
The cutting (as opposed to the molar or grinding) lobe of the mandible [Hobbs, Hobbs, and Daniel 1977].
The distal biting part of the mandible that typically bears one or more cusps. On its medial side, it bears the spine row [Wilson, 1989].
The fixed distal 'cutting blade' of the mandible [Holdich and Jones, 1983].
(Class Cephalocarida):
Food-gripping process (vs. grinding = molar process) at end of each mandible) Extends into atrium oris under labrum. Variously armed with spines, setae, and denticles [Stachowitsch, 1992].
(Order Cumacea):
Distal gripping process (vs. grinding = molar process) of each mandible. (Syn. pars incisiva) [Stachowitsch, 1992].
(Order Tanaidacea):
Distal gripping process (vs. grinding = molar process) of each mandible [Stachowitsch, 1992].
(Order Decapoda):
Food-gripping process (vs. grinding = molar process) of each mandible. May be fused with molar process. (Syn. pars incisiva) [Stachowitsch, 1992].
(Order Amphipoda):
Gripping process (vs. grinding = molar process) of each mandible [Stachowitsch, 1992].
(Order Isopoda):
Distal, often toothed gripping process (vs. grinding = molar process) of each mandible [Stachowitsch, 1992].
(Order Isopoda):
Grasping, piercing or slicing structure arising apically on body of mandible [Wetzer et al. 1997].

Nomenclature of isopod cephalon (A). Examples of isopod mouth appendages: Idoteidae (B, C, F, H); Cirolanidae (D, E, G, I). [Wetzer et al. 1997]
(Order Mysida):
Distal gripping process (vs. grinding = molar process) of each mandible [Stachowitsch, 1992].
(Order Stomatopoda):
Well-developed food-gripping (vs. grinding = molar process) of each mandible; bears single row of teeth and lies over labrum. (Syn. pars incisiva) [Stachowitsch, 1992].
(Order Leptostraca):
Gripping process (vs. grinding = molar process) of each mandible. (simple, with teeth) [Stachowitsch, 1992].
(Class Remipedia):
Cutting process (vs. grinding = molar process) at tip of each mandible; incisor processes of left and right mandibles are generally asymmetrical, i.e., number (three or four) and shape of large denticles differ [Stachowitsch, 1992].
(Superorder Syncarida):
Distal gripping process (vs. proximal grinding = molar process) of each mandible [Stachowitsch, 1992].
(Order Thermosbaenacea):
Distal gripping process (vs. grinding = molar process) of each mandible [Stachowitsch, 1992].
(Order Euphausiacea):
Gripping process (vs. grinding = molar process) of each mandible [Stachowitsch, 1992].
