- [Martin, 2005]
- See proctodeum. [McLaughlin, 1980]
- (Taxon-specific: ) Short posteriormost section of digestive tract between midgut and anus; may be associated with single ventral cecum.
(syn. rectum) [Stachowitsch, 1992] - Short posteriormost section of digestive tract between midgut and anus.
(syn. rectum) [Stachowitsch, 1992] - Short posteriormost section of digestive tract between midgut and anus. [Stachowitsch, 1992]
- (Taxon-specific: Family Pycnogonidae) Short posteriormost section of digestive tract between midgut and anus. [Stachowitsch, 1992]
- Elongate section of digestive tract between midgut and anus. Extends through most of pereon and abdomen and may be coiled in the former. [Stachowitsch, 1992]
- Posteriormost cuticle-lined region of digestive tract (foregut, midgut, hindgut). Opens via rectum and anus to exterior.
(syn. proctodeum, proctodaeum) [Stachowitsch, 1992] - Posterior of three basic divisions (foregut, midgut, hindgut) of digestive tract. Cuticle-lined and opening to exterior via anus.
(syn. proctodeum, rectum) [Stachowitsch, 1992] - Posterior of two basic divisions (foregut, hindgut) of digestive tract; elongate, typically extending through part of pereon and entire abdomen (pleon). Opens posteriorly via anus at base of lelson. [Stachowitsch, 1992]
- Relatively short, cuticle-lined section of digestive tract between midgut and anus. Restricted to last (sixth) abdominal somite (pleomere). [Stachowitsch, 1992]
- Posterior section of digestive tract; follows midgut at level of fifth abdominal somite (pleomere). Opens to exterior via anus on telson. [Stachowitsch, 1992]
- (Taxon-specific: Class Secernentea) Posterior region of digestive tract (foregut, midgut, hindgut); extends through one or more abdominal segments and opens to exterior via anus. If present, rectal cecum extends above hindgut. [Stachowitsch, 1992]
- (Taxon-specific: Order Monhysterida) Posterior of three regions (foregut, midgut, hindgut) of digestive tract; extends through abdomen and opens to exterior via anus.
(syn. rectum) [Stachowitsch, 1992] - (Taxon-specific: Order Rhabditida) Posteriormost, relatively narrow, cuticle-lined section of digestive tract between midgut and anus. [Stachowitsch, 1992]
- (Taxon-specific: Family Cyatholaimidae) Posterior of three regions (foregut, midgut, hindgut) of digestive tract. Relatively short, extending only through last two abdominal somites; opens to exterior via anus. Cuticle-lined and equipped with muscles.
(syn. proctodeum) [Stachowitsch, 1992] - Proctodeum. [Stachowitsch, 1992]
- Posterior of three regions (foregut, midgut, hindgut) of digestive tract. Relatively short, cuticle-lined, and opening to exterior via anus. [Stachowitsch, 1992]
- Short posteriormost division of digestive tract (foregut, midgut, hindgut) located in anal segment. Opens to exterior via anus. [Stachowitsch, 1992]
- In anaspidacean, relatively short section of digestive tract between midgut and anus; restricted to last (sixth) abdominal somite (pleomere). [Stachowitsch, 1992]
- Posteriormost section of digestive tract between midgut and anus; may give rise to short blind diverticulum. [Stachowitsch, 1992]
