For example, the harlequin beetle riding pseudoscorpion, Cordylochernes scorpioides (Linnaeus 1758), ranging from Costa Rica to southern Brazil, was described by Beier (1948) as a single species, based on morphological examination of hundreds of specimens from several countries in South and Central America.
Scientists are also concerned about the swift advance of the harlequin beetle across England which poses a risk to native wildlife.

The phoretic differentials reported here demonstrate that in both populations males engage in intense, size-based competition to monopolize harlequin beetle mating territories.
For example, in the harlequin beetle, Acrocinus longimanus, coefficients of variation in male sexually dimorphic traits of the foreleg vary between 25% and 30%.
Sexual selection and sexual dimorphism in the harlequin beetle Acrocinus longimanus.
Finally, we compared the two populations for the intensity of size-based male competition to monopolize harlequin beetles as mating territories, an important component of dispersal-generated sexual selection (see Zeh and Zeh 1992a).
scorpioides inhabit decaying trees for several generations before dispersing by climbing under the elytra of giant harlequin beetles (Acrocinus longimanus) as beetle adults eclose from the tree (Zeh et al.
Moraceae), which act as the primary hosts for harlequin beetles and Cordylochernes scorpioides.
In Panama, pseudoscorpions were collected from 113 harlequin beetles and sampled from 16 tree populations.
