Rare eggshell structure in Odonata: Lindenia tetraphylla (Van der Linden) (Anisoptera: Gomphidae)

Lindenia tetraphylla (Van der Linden, 1825) eggs exhibit an egg structure that is very rare in other Gomphidae species. They have a well-developed surface reticulation structure. The anterior pole of the egg has a small, rounded micropylar area consisting of 7 orifices arranged radially around a central area. The posterior pole has a sessile, truncated cone that carries 55-65 coiled filaments. This study provides a detailed analysis of the ultrastructure of L. tetraphylla eggs using scanning electron microscopy, and the functional and taxonomic significance of the eggshell are discussed.
