Ovipositor Internal Microsculpture in the Relic Silverfish Tricholepidion gertschi (Insecta: Zygentoma)
Figure 3
SEM micrographs of the inside surface of the 9th gonapophysis of Tricholepidion gertschi: (a) transverse sculptured field in the middle part of the gonapophysis, with longitudinal ridges and wrinkles dorsally and squamous microsculpture ventrally; (b) transverse sculptured field in the subapical part of the gonapophysis, with longitudinal ridges and wrinkles, ventrally replaced by spine-bearing scales and microtrichia; (c) fragment of the integument turned inside out to show the density of dome-shaped sensilla (underside surface of the sensillum is enlarged in inset); (d) rhachis. Arrowheads indicate dome-shaped sensilla. GA9, the gonapophyses of the 9th segment. and : distal and ventral directions, respectively.
