Figure 4
SEM micrographs of the inside surface of gonapophyseal apices in Tricholepidion gertschi: (a) distal part of the 8th gonapophysis (inset is enlarged in (b)); (b) dorsal margin of the 8th gonapophysis showing smooth tablet-like fields and short microtrichia above; (c) apical part of the 9th gonapophysis with tablet-like fields and short microtrichia below; (d) subapical part of the 9th gonapophysis showing smooth tablet-like fields. Arrowheads indicate dome-shaped sensilla. 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.
