Tarsal pads of Centrobolus Cook (Spiroboloidea: Trigoniulidae)
Mark Ian Cooper
The tarsal pads of three species of Centrobolus were examined using Scanning Electron Microscopy (SEM). Tarsal pads of C. inscriptus are robust and prominent (± 1018 um, n = 10) extending to about the mid length of the tarsal claws compared to C. annulatus (± 540 um, n = 8) which were abbreviated. Elaborate tarsal pads of the males appear not to be an adaptation for supporting the body column but sexually selected.
