Paragnath

See: Labium, Metastoma [Martin, 2005]
A pair of ventral projections of the cephalic cuticle just posterior and medial to the mandibles. Each projection has two lobes, a broad lamellar outer lobe with hair-like setae on the inner margins and a thick inner lobe covered with many hair-like setae.
(syn. paragnathae or lower lips) [Wilson, 1989]
See metastoma. [McLaughlin, 1980]
(Taxon-specific: ) Labium. [Stachowitsch, 1992]
One of a pair of lobe-like structures between mandibles and maxillules posterior to mouth. Considered to represent either true lower lip or additional lobe of each maxillule. [Stachowitsch, 1992]
(Taxon-specific: Family Pycnogonidae) On underside of head, structure posterior to mouth between mandibles and maxillules; considered to represent or at least function as lower lip. [Stachowitsch, 1992]
Labium. [Stachowitsch, 1992]
Labium. [Stachowitsch, 1992]
In isopods, the labium is usually produced and cleft into a large bilobed structure, and hence more commonly referred to as the paragnath (=hypostome, mesastome, hypopharynx). [Wetzer et al. 1997]
One two lobes of labium. [Stachowitsch, 1992]
Labium. [Stachowitsch, 1992]
Labium. [Stachowitsch, 1992]
(Taxon-specific: Class Secernentea) One of two lobe-like structures forming lower lip (labium) posterior to mouth. [Stachowitsch, 1992]
(Taxon-specific: Order Monhysterida) One of two lobes of lower lip (labium); either papilla-shaped elevations posterior to mouth or reduced, along with labrum, to serrate flap enclosed in proboscis. [Stachowitsch, 1992]
(Taxon-specific: Family Cyatholaimidae) A pair of articulating lobes often bearing setae and located posterior to the mandible and anterior to maxilla 1. Homologies of the paragnath have not been determined, but it may be the praecoxa of the mandible or it may be that section of the praecoxa of maxilla 1 bearing a second lobe. [Ferrari and Dahms, in press]
(Taxon-specific: Family Cyatholaimidae) A small paired lobe located on ventral surface of cephalosome, between the bases of mandibles and maxillules. [Boxshall and Halsey, 2004]
Labium. [Stachowitsch, 1992]
One of two lobes of lower lip (labium). [Stachowitsch, 1992]
One of a pair of lobes flanking opening (atrium oris) to mouth; margin of each paragnath bear dense cover of ribbon setae. [Stachowitsch, 1992]
One of two lobe-like structures forming lower lip (labium) posterior to mouth. [Stachowitsch, 1992]
Labium. [Stachowitsch, 1992]
One of two lobe-like structures forming lower lip (labium) posterior to mouth. [Stachowitsch, 1992]
