The white spots...
mark the cuplike cuticular depressions in which the bothriotricha are placed. Bothriotricha are mechanoreceptive sensilla that can sense movements of the shaft of the sensillum in all directions (kind of like in a computer game joystick). They are present in all Tomoceridae but are distinctly visible in this dark species.
