pleotelson
Pleonite 6 (sometimes 5 and 6) fused to telson [Holdich and Jones, 1983].
Structure formed by fusion of one or more abdominal somites with telson, as in most isopods [Moore and McCormick, 1969].
Structure formed by fusion of one or more abdominal somites with telson [Butler, T.H.].
The abdominal part of the body, consisting of a short segment (pleonite 1) and a long and broad segment. The large segment is made of the fused more posterior pleonites and the telson, a terminal segment bearing the anus. Primitively, there are six pleonites: the anterior five bear ventral pleopods, and the sixth bears the uropods. In Janiroidea, only the first pleonite is expressed as a free segment [Wilson, 1989].
(Order Cumacea):
Structure formed by fusion of last (sixth) abdominal somite (pleonite) with telson [Stachowitsch, 1992].
(Order Tanaidacea):
Terminal segment of body formed by fusion of telson with last (sixth) or fifth and sixth abdominal somites (pleomeres) [Stachowitsch, 1992].
(Order Isopoda):
In all isopods the sixth pleonite is fused to the telson to form a pleotelson. In anthurideans the line of fusion is often visible as a deep dorsal groove or fold [Wetzer et al. 1997].
(Order Isopoda):
Structure resulting from the fusion of the telson and one or more pleonal segments [Kensley and Schotte, 1989].
(Order Isopoda):
Terminal structure of body formed by fusion of one or more abdominal segments (pleonites) with telson [Stachowitsch, 1992].
(Order Stomatopoda):
Telson [Stachowitsch, 1992].
(Order Thermosbaenacea):
In certain thermosbaenaceans, terminal segment of body formed by fusion of telson with last (sixth) abdominal somite (pleomere) [Stachowitsch, 1992].
