The behavioral and external morphological observations on oviposition and postembryonic development in Galeodes hakkariensis Erdek 2021 (Solifugae: Galeodidae).

Oviposition was observed in Galeodes hakkariensis Erdek 2021. Part of the developmental changes post-hatch were recorded, and the cuticular surfaces of egg and first post-embryos were surveyed with a scanning electron microscope. This species has oval-shaped eggs varying from 2 mm to 4 mm in diameter. The fine structure of the external morphology of post-embryos in a solifuge is shown for the first time. The cuticular patterns and sensilla on opisthosoma and tarsal sensilla on each pedipalp and leg were described in post-embryos. The surface of each opisthosomal basiconic sensilla without the socket is covered with pores, likely functioning as chemoreceptors. Tarsal basiconic sensilla not in a socket and without pores on pedipalps and legs likely function as mechanoreceptors. The single slit sensillum on the tarsus of pedipalps functions as mechanoreceptors. [ABSTRACT FROM AUTHOR]
