trunk appendage
(Order Cladocera):
One of four to six pairs of appendages of anterior region ("thorax") of trunk. Basically biramous, consisting of indistinct proximal protopod (with endites and epipod) and more distal endopod and exopod. (flattened = foliaceous = phyllopodus, not clear segmented; subcylindrical = prehensile, clearly segmented; similar, dissimilar). (Syn. thoracic appendage, thoracopod) [Stachowitsch, 1992].
(Order Diplostraca):
One of two relatively elongate appendages of each trunk somite. Basically biramous, consisting of poorly delimited, proximal protopod (with endites and epipod), endopod (= sixth endite), and exopod (flabellum). Decreases in size posteriorly. Unmodified trunk appendages are termed phyllopods due to flattened construction. (Syn. thoracic appendage, thoracopod, trunk leg) [Stachowitsch, 1992].
(Class Ostracoda):
Thoracopod. (Syn. postcephalic appendage) [Stachowitsch, 1992].
