Figure 8 in Ultrastructure of the prosomal gland complex in unfed larvae of the fresh-water mite Limnesia maculata (Müller, 1776) (Acariformes, Limnesiidae)

Figure 8 Organization of the labyrinth of coxal glands in unfed larvaeL. maculata.TEM. a – Central portion of the labyrinth with a conspicuous central lumen filled with various membranous and granular structures. Scale bar – 2 μm; b – Portion of the labyrinth with a collapsed lumen penetrated by microvilli. Scale bar – 2 μm; c – Basal lamina penetrating between the gland cells at their base (arrow). Scale bar – 0.5µζ; d – Portion of the convoluted labyrinth showing semi-circled mutual invagination of the gland cells (arrow). Scale bar – 1 μm; e – The apical cell contact with hardly distinguishable septate junction (arrow). Note axial filaments within microvilli (arrowheads). Scale bar – 0.5 μm. gl – glycogen; gll – gland lumen; m – mitochondria; mg – midgut; mt – microtubules; mv – microvilli; n – nucleus; nu – nucleolus; rb – residual body; rer – rough endoplasmic reticulum.
