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].
