Laterodorsal sclerite differentiation in flat mounted post-hatching juveniles of <i>Strigamia maritima</i>.

<p>All images orientated with anterior to the left. Images with the same letter indicate same specimen. All specimens photographed with fluorescent nuclear staining (Sytox Green) to show the morphology. <b>A.</b> Laterodorsal view of juvenile showing anterior trunk region and completed dorsal closure indicated by dorsal midline (<i>dm</i>). <b>A1.</b> Close up showing incipient formation of the longitudinal pleural furrows (<i>lpf</i>) in the lateral region. <b>B.</b> Laterodorsal view of juvenile, showing middle trunk region. <b>B1.</b> Close up showing similar morphological features as A1 for the middle of the trunk. The intersection between the longitudinal furrows and the tergite borders (<i>solid line</i>) form quadrants that will become distinct sclerites. The position of the intercalary furrow (<i>if</i>/<i>dashed line</i>) indicates that the presumptive tracheal pits (<i>tp</i>) are aligned with the metatergite (<i>mt</i>). Scale bars: 200 µm for A, B; 100 µm for A1, B1.
