carapace regions

carapace regions
(Order Decapoda):
(a) antennal. Anterior marginal part bordering orbital region laterally, adjoining hepatic, pterygostomial, and occasionally also frontal regions.
(b) anterolateral. Lateral part bordering subhepatic or hepatic regions.
(c) branchial. Lateral part posterior to ptergostomial region, overlying branchiae; epibranchial, mesobranchial, and metabranchial lobes or areas sometimes distinguished.
(d) cardiac. Median part posterior to cervical groove between urogastric and intestinal regions.
(e) frontal. Anteromedian part including rostrum and region behind it.
(f) gastric. Median part posterior to cervical groove and posterior to frontal region; sometimes epigastric, mesogastric, metagastric, protogastric, and urogastric (genital) areas distinguished.
(g) hepatic. Part adjoining antennal, cardiac, and pterygostomial regions.
(h) intestinal. Short traverse part posterior to cardiac region; sometimes referred to as posterior cardiac lobe.
(i) jugal. See: pterygostomial region.
(j) orbital. Part posterior to eyes bordered by frontal and antennal regions.
(k) pterygostomial. Anterolateral part on ventral surface located on opposite sides of buccal cavity; Syn., jugal region, pterygostome.
(l) subhepatic. Part on ventral surface below hepatic region, bounded by pterygostomial and suborbital regions.
(m) suborbital. Part on anteroventral surface beneath orbit [McLaughlin, 1980].
