Overview of investigated morphological features. Schematic overview of malacostracan embryo or larva. The left hemisegments are shown in ventral view and hemisegments from the second thoracomere to the fifth pleomeres are excluded. A vertical dotted line at the left marks the longitudinal body axis. Anlagen of appendages, muscle precursor groups, and primordial elements of the nervous system are outlined and color-coded. The naupliar segments (bearing first antenna, second antenna, and mandible) and postnaupliar segments (all segments posterior to the mandible-bearing segment) are indicated by brackets on the right. Abbreviations: Ol optic lobe; pc protocerebral ganglion anlage; dc deutocerebral ganglion anlage; tc tritocerebral ganglion anlage; NGA naupliar ganglion anlagen; NEA nauplius eye anlage; PPN posterior pioneer neurons; A1-P6 appendage anlagen of the first antennal to the sixth pleonal hemisegments; T2-P5 excluded trunk segments; st stomodeal muscle precursor group, m medial extrinsic appendage muscle precursor groups; l lateral extrinsic appendage muscle precursor groups; lmp-post posterior longitudinal muscle precursor strand.
