Description

Figure 3. Ultrastructure of the projections on the mouthparts. A, cross-section of the basal part of type I projection, which is circular in cross-sectional shape. The lumen is filled with semicircular sheath cells. Arrow indicates bundle of sensory cilia. B, close-up of semicircular sheath cells (arrow) in the basal part of a type I projection encircling the sensory cilia. C, cross-section of the basal part of a type II projection. Arrow indicates semicircular sheath cells. D, oblique section of a type IV projection, note no lumen or sheath cells. Arrowhead indicates articulation. E, cross-section of the basal part of a type IV projection showing flattened shape and no lumen. F, oblique and cross-section of setules from a pappose seta. Arrowheads indicate cross-sections, arrow indicates the articulation with the cuticle of the setal shaft. G, cross-section of setules and denticles from the distal part of a serrate seta. Arrow indicates lumen of seta. Abbreviations: D, denticle; Ge Cu, general cuticle; S, setule; Se Cu, cuticle of seta; SC, sensory cilium.
