Trachythorax is an Asian genus of stick insects in the family Lonchodidae and subfamily Necrosciinae. Species have been recorded from the Indian subcontinent, Indo-China, Malesia through to New Guinea.Phasmida Species File (Version 5.0/5.0: retrieved 16 February 2021)
The genus has males much smaller than females. Both sexes are winged and active fliers. The mesonotum is often strongly raised. A brightly coloured membranous ring shows between the pronotum and the head and most species lay eggs in clusters with the eggs having a flower-like collar radiating around them. This architecture might be an adaptation against parasitoid wasps.
