To our knowledge the present study is the first to use scanning electron microscopy to quantify variation in the entire structure of the cypris antennule
Adult female holotype partially dissected as follows: habitus, right antennule
, labrum, and P5 left intact and preserved in alcohol (ICML-EMUCOP-010815-11); left antennule
, antennae, mandibles, maxillulae, maxillae, P1-P4 dissected (ICML-EMUCOP-010815-12) and mounted onto four slides; Colombia, Magdalena, Rodadero Bay, 11[degrees]14' North, 74[degrees]12' West; August 2015; coll.
In Chonopeltis, morphological differences include the absence of a pre-oral spine, trifoliate carpace and the absence of antennules
(Tam et al.
A) Habitus, dorsal; B) Left antennule
, ventral; C) Left antenna, posteromedial; D) Left antenna, anterolateral; E) Distal endopodal segment of left antenna, posterior; F) Left maxillule (MX1) and postoral process (POP), ventral.
A single pair of relatively large, ear-shaped cuticular processes is found on the anterior ventral surface between antennule
bases and oral papilla (arrowed in Figs.
Antennular seta inserted at about 1/3 from tip of antennule
Another possibility is that it compares information between the left and right antennule
every second and makes moment-by-moment decisions about where to move.
Based on its length, each antennule
was divided into the lateral and medial flagella, and each flagellum was subsequently separated into three parts.
seven-segmented; male antennule
haplocer, nine segmented.

In addition, she classified Farfantepenaeus into two groups according to the shape and position of the rostrum with respect to the segments and flagellum of the antennule
and the ratio RL/CL: 1) F.
