Fig. 4

Palpal organ of Kukulcania hibernalis; external morphology (b), histology (c, d) ultrastructure as documented by TEM (e, f) and 3D reconstruction of the spermophor (green), nervous tissue (yellow) and internalized sensilla/“tube-like-structures” (red) as based on segmentation of histological image stacks (a). Arrows indicate the planes chosen for semithin sectioning (b) and the arrowhead marks the terminals of the bulb nerve (a). Box in C marks the sector with internalized aggregated sensilla magnified in (e), whereas box in (d) frames the region around the bulb nerve magnified partly in (f). Inset in (e) highlights four dendritic outer segments assembled in an internalized sensillum. Abbreviations: Coe Coenospermium, Cy Cymbium, DOS Dendritic outer segments, Ecm Extracellular Matrix, E Embolus, Gli Glial cell processes, HS Haemolymph space, HV Haemolymph vessel, Ne Neurite, S Spermophor, SF Seminal fluid, SLS Sensillum lymph space, TLS aggregated tube-like structures
