Specific glandular systems in Lobatocerebrum riegeri n. sp. as seen with CLSM and TEM. DAPI in cyan, acetylated α-tubulin in glow or yellow, actin-filaments in green. c, g, h are maximum intensity projections of a subset of the original image stack on various locations of the body, a, b, d–f ultrastructural details of glandular structures. a Sagittal section through the epidermis and an unicellular adhesive gland, b Sagittal section through an unicellular adhesive and a ciliated gland in the epidermis, c brain and portions of the anterior and posterior frontal glands (indicated by white dashed line), d Sagittal section through the anterior tip of the rostrum with ducts of the posterior frontal glands and nerves, e Sagittal section through the mouth opening with glandular cells of the posterior frontal gland and the pharyngeal gland, f Sagittal section through the pharyngeal region with distal parts of the pharyngeal glands, g Distal regions of the ducts of the pharyngeal glands, h Glands around the male gonopore. Abbreviations: afg: anterior frontal gland, ag: adhesive granule, cg: ciliated gland cell, dfg: ducts of the frontal gland, dphg: ducts of the pharyngeal gland, ec: cilia of an epidermis-cell, gg: glandular granules, gv: glandular vesicle, ksg: kidney-shaped gland, lca: major caudal lobe, lci: minor caudal lobe, lrl: lateral rostral lobe, lra: major rostral lobe, mo: mouth opening, mg: male gonopore, mgg: male gonopore gland, np: neuropil, pfg: posterior frontal gland, sc: shortened cilium, spd: spermioduct, ssn: sickle-shaped nucleus, uag: adhesive gland cell
