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]
(Taxon-specific: 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]
(Taxon-specific: Order Cumacea) Distal gripping process (vs. grinding = molar process) of each mandible.
(syn. pars incisiva) [Stachowitsch, 1992]
(Taxon-specific: Order Tanaidacea) Distal gripping process (vs. grinding = molar process) of each mandible. [Stachowitsch, 1992]
(Taxon-specific: Order Decapoda) Food-gripping process (vs. grinding = molar process) of each mandible. May be fused with molar process.
(syn. pars incisiva) [Stachowitsch, 1992]
(Taxon-specific: Order Amphipoda) Gripping process (vs. grinding = molar process) of each mandible. [Stachowitsch, 1992]
(Taxon-specific: Order Isopoda) Distal, often toothed gripping process (vs. grinding = molar process) of each mandible. [Stachowitsch, 1992]
Nomenclature of isopod cephalon (A). Examples of isopod mouth appendages: Idoteidae (B, C, F, H); Cirolanidae (D, E, G, I). [Wetzer et al. 1997]
(Taxon-specific: Order Isopoda) Grasping, piercing or slicing structure arising apically on body of mandible. [Wetzer et al. 1997]
(Taxon-specific: Order Mysida) Distal gripping process (vs. grinding = molar process) of each mandible. [Stachowitsch, 1992]
(Taxon-specific: 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]
(Taxon-specific: Order Leptostraca) Gripping process (vs. grinding = molar process) of each mandible. (simple, with teeth). [Stachowitsch, 1992]
(Taxon-specific: 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]
(Taxon-specific: Superorder Syncarida) Distal gripping process (vs. proximal grinding = molar process) of each mandible. [Stachowitsch, 1992]
(Taxon-specific: Order Thermosbaenacea) Distal gripping process (vs. grinding = molar process) of each mandible. [Stachowitsch, 1992]
(Taxon-specific: Order Euphausiacea) Gripping process (vs. grinding = molar process) of each mandible. [Stachowitsch, 1992]
