Between two appendages of a pair, setules link the medialmost setae of each endopod
. Like the cross-linkage between podites, pairs of setules from opposing setae are fused at their tips and lack any connection between the separate pairs of setules.
lerneri by having a shorter endopod
relative to the exopod on legs 2-4, apical claws on the terminal exopodal segment of leg 1 that are as long as the first exopodal segment of leg 1, and subequal middle and inner apical setae on the exopod of leg 5.
The following abbreviations are used in the descriptive section: P1--P6= first to sixth swimming legs, EXP= exopod, ENP= endopod
, aps = apical seta, ins= Inner seta, Fig = Figure, UARC = Universidad del Atlantico Region
5H) protopod quadrangular; endopod
much longer than exopod, both with very long apical setae.
Poly (2003) discussed that the number of setae (spine) on the endopod
of the first leg and number of setae on the caudal rami may be useful characters for taxonomy or systematics: three setae on the endopod
of the first leg possess species: A.
Setal armature of appendages is described from proximal to distal segments and in order of endopod
to exopod (Clark et al.
We used a light microscope and 400 x magnification to inspect the second antenna and the associated exopod and endopod
. Based on these structures, we identified the gill lice to species using characteristics described in Kabata (1988).
Fourth leg bifurcated forming endopod
and exopod (Figure 4(b) ii).
The fourth male pleopod showed early differentiation in endopod
and expod at sizes above 4.0 mm.
To determine the sex of any individual that was not obviously female (i.e., shrimps with embryos or maturing ovaries), the presence (male) or absence (female) of an appendix masculina on the endopod
of the second pleopod (swimmeret) was recorded.
