epipod

epipod
() [Holthuis, 1993].
Schematic drawing of a thoracic leg. [Holthuis, 1993]
A lateral extension from the base of an appendage (Fig. 2) [Warner, 1977].
A respiratory endite arising from the coxal segment of a pereiopod [Ingle, 1983].
A small projection arising from the thoracic legs [Mauchline, 1984].
Lateral branch of limb attached sometimes with gill (podobranch) to coxa, coxal endite. (Syn. epipodite) [Poore, 2004].
Lateral exite of the coxa of a thoracic appendage, sometimes branchial in function (Fig. 3C) [Perez Farfante and Kensley, 1997].
Laterally directed lobe (exite ) of the basal segment (coxa ) of the maxilliped [Wilson, 1989].
Laterally directed ramus (exite) of coxa; may be present or absent [Moore and McCormick, 1969].
Respiratory process arising from coxa of a thoracic appendage; usually elongate and flat, but may be folded; has taxonomic value [Butler, T.H.].
(Order Cladocera):
In trunk appendage, laterally (outwardly) directed lobe projecting from base of protopod. Represents only lobe articulated with appendage and serves in respiration. (Syn. epipodite) [Stachowitsch, 1992].
(Order Notostraca):
Dorsally directed lobe extending from lateral (outer) margin of thoracic appendage (thoracopod) or abdominal appendage. Serves in respiration. (Syn. epipodite) [Stachowitsch, 1992].
(Order Diplostraca):
In trunk appendage, fleshy, lobe-like projection from base of protopod. Serves, along with inner wall of carapace, in respiration. Dorsally directed part of flabellum may also represent an epipod. (Syn. epipodite) [Stachowitsch, 1992].
(Order Anostraca):
In thoracic appendage (thoracopod), laterally (outwardly) directed lobe of protopod; located distal to preepipod(s). Serves in respiration. (Syn. epipodite) [Stachowitsch, 1992].
(Class Cephalocarida):
Pseudepipod [Stachowitsch, 1992].
(Order Cumacea):
In first pair of maxillipeds, enlarged lateral lobe of first segment (coxa). Consists of two parts, the first directed posteriorly into branchial chamber and bearing branchial lobules, the second (siphonal lobe) directed anteriorly to form part of siphon (the latter may alternately be interpreted as representing an exopod). (Syn. epipodite) [Stachowitsch, 1992].
(Order Tanaidacea):
Well-developed projection of first segment (coxa) of each maxilliped. If fully developed, consists of stalk-like proximal section (muscular peduncle) and distal expanded section. The latter may further bear small lobe basally and finger-like process (terminal spine) terminally. Projects posteriorly into branchial chamber and serves in respiration. (kidneyshaped, sickle-shaped, spoon shaped). (Syn. epipodite) [Stachowitsch, 1992].
(Order Amphipoda):
In appendage (pereopod) of pereon, inwardly directed lobe of protopod. Serves in respiration and therefore frequently termed coxal gill or branchia. (Syn. epipodite) [Stachowitsch, 1992].
(Order Isopoda):
() [Wetzer et al. 1997].
Nomenclature of isopod cephalon (A). Examples of isopod mouth appendages: Idoteidae (B, C, F, H); Cirolanidae (D, E, G, I). [Wetzer et al. 1997]
(Order Isopoda):
Lateral extension of a protopodite [Kensley and Schotte, 1989].
(Order Mysida):
Dorsal projection from outer branch (exopod) of thoracopods. First thoracic epipod extends dorsally and posteriorly under carapace and serves to renew water supply for respiration. In certain mysidaceans, epipods of thoracopods 2-7 form ramified gills (branchiae). (Syn. epipodite) [Stachowitsch, 1992].
(Order Stomatopoda):
Laterally directed branch of base of first five thoracic appendages (thoracopods); with respiratory function in thoracopods 3-5. (Syn. epipodite) [Stachowitsch, 1992].
(Order Leptostraca):
In thoracic appendage (thoracopod), laterally (outwardly) directed lobe of protopod. Serves in respiration. (Syn. epipodite) [Stachowitsch, 1992].
(Subclass Branchiura):
Flabellum [Stachowitsch, 1992].
(Class Ostracoda):
Extension (usually setose flat lobe) of lateral protopod; in ostracodes it often forms a branchial plate used to circulate water [Cohen, Peterson, and Maddocks, in press].
(Class Ostracoda):
Laterally directed lobe of protopod. May also refer to modified exopod (branchial plate) of appendage. (Syn. epipodite) [Stachowitsch, 1992].
(Superorder Syncarida):
One of two projections of first segment (coxa) of thoracopod. Serves in respiration. (Syn. epipodite) [Stachowitsch, 1992].
(Order Thermosbaenacea):
Projection of basal section (protopod) of each maxilliped. Extends posteriorly under carapace, serving in respiration and ventilation of brood pouch in female. (Syn. epipodite) [Stachowitsch, 1992].
(Order Euphausiacea):
Laterally (outwardly) directed lobe of basal segment (coxa) of thoracic appendage (thoracopod). Those of second through eighth thoracopods serve in respiration and are therefore termed gills or podobranchs. (Syn. epipodite) [Stachowitsch, 1992].
