Postcephalic portion of body. (Syn. thorax) [Moore and McCormick, 1969].
Postcephalic portion of body [McLaughlin, 1980].
The postcephalic body of a crustacean, sometimes divisible into an anterior thorax and posterior abdomen [Brusca and Brusca, 2002].
(Order Cladocera):
Posterior of two divisions (tagmata) of body (head, trunk). Trunk may be considered to consist of thorax, abdomen, and postabdomen, whereby thorax refers to anterior appendage-bearing region of trunk, abdomen to (reduced) region posterior to trunk appendages, and postabdomen to recurved posteriormost region. Somite border indistinguishable in posterior region of trunk. (covered/not covered by valves) [Stachowitsch, 1992].
(Order Notostraca):
Region of body posterior to head. Consists of thorax with 11 segments and abdomen with large and variable number of body rings; anterior region covered by carapace. Term is frequently applied due to poorly delimited border between thorax and abdomen [Stachowitsch, 1992].
(Order Diplostraca):
Posterior of two divisions (tagmata) of body (head, trunk); consists of 10-32 somites (excluding telson), each bearing pair of appendages. Considered to basically consist of thorax and abdomen, although the two are indistinguishable. (Syn. postcephalic body) [Stachowitsch, 1992].
(Order Anostraca):
Region of body posterior to head. Typically consists of 19 postcephalic segments (excluding telson), of which the first 11 represent the thorax, the last 8 the abdomen [Stachowitsch, 1992].
(Class Cephalocarida):
Region of body posterior to head (cephalon). Consists of 19 segments (excluding telson), of which first 8 represent the thorax, the last 11 the abdomen [Stachowitsch, 1992].
(Subclass Copepoda):
The postcephalic region of the body [Boxshall and Halsey, 2004].
(Subclass Mystacocarida):
Entire region of body following head (cephalon); according to interpretation, may be subdivided into thorax and abdomen or maxillipedal somite and thoracoabdomen [Stachowitsch, 1992].
(Class Ostracoda):
Region of body posterior to head; corresponds to thorax (and rudimentary abdomen). Unsegmented, typically bearing two pairs of appendages (thoracopods) and caudal rami. Entirely enclosed in carapace [Stachowitsch, 1992].
(Class Ostracoda):
Term applied to region of body posterior to head (i.e., thorax and abdomen). Refers also to more expanded part of thorax posterior to neck in parasitic copepod [Stachowitsch, 1992].
(Class Remipedia):
Posterior division of body (cephalon, trunk). Consists of up to approximately 30 similar segments, the first (i.e., maxillipedal) being fused to head (cephalon), the second (= apparent first) being sometimes partially covered by head (cephalon), the last reduced and partially fused anal segment; each segment is produced laterally into pleurites and bears pair of biramous appendages [Stachowitsch, 1992].
