Ovipositor Internal Microsculpture in the Relic Silverfish Tricholepidion gertschi (Insecta: Zygentoma)
Figure 2
SEM micrographs of the inside surface of the gonapophyses in Tricholepidion gertschi: (a) middle part of the 8th gonapophysis; (b) dorsal margin of the 8th gonapophysis showing microtrichia, sensilla, and longitudinal ridges; (c) one transverse sculptured field of the 8th gonapophysis; (d) aulax; (e) basal part of the 8th gonapophysis with spine-bearing scales and sensilla; (f) basal part of the 9th gonapophysis with squamous microsculpture and sensilla (one sensillum is enlarged in inset). Arrowheads indicate uniform dome-shaped sensilla, externally identical to the campaniform sensilla with a central moulting pore on the ovipositor of the glassy-winged sharpshooter, Homalodisca coagulata [13, Figure 4]. Arrows indicate ventral corrugations of the 8th gonapophysis. GA8 and GA9: the gonapophyses of 8th and 9th segments, respectively. and : distal and ventral directions, respectively.
