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

[摘要] Oviposition was observed in Galeodes hakkariensis Erdek 2021. Part of the developmentalchanges post-hatch were recorded, and the cuticular surfaces of egg and first post-embryos were surveyed witha 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. Thecuticular patterns and sensilla on opisthosoma and tarsal sensilla on each pedipalp and leg were described inpost-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 pedipalpsand legs likely function as mechanoreceptors. The single slit sensillum on the tarsus of pedipalps functions asmechanoreceptors.
