Differences in the disposition of trichobothria in the Chernetidae (Pseudoscorpiones)



An analysis of the disposition of trichobothria in all the post-embryonic stages of six British species of Chernetidae, similar to that employed by Gabbutt (1969) in his study of the Neobisiidae, shows that a linear relationship exists between the successive position of named trichobothria. A model, based on growing and non-growing regions gives a good approximation to the data. The results are considered in relation to the use of trichobothrial position as an adult generic or specific character and as a device for separating the nymphs of this family.
