Notes

The male specimens from TLFES bear no labels and cannot be ascertained to come from Hong Kong (although more than likely in view of the history/mission of the insect collection at TLFES).

Campsomeriella collaris is a widely distributed species that has been divided between five subspecies (Gupta & Jonathan 2003) with C. c. quadrifasciata (Fabricius 1798) being the subspecies previously recorded from southeast China (Betrem 1941). This subspecies has been distinguished from the nominotypical subspecies of India and Sri Lanka by the presence of fulvous reddish vestiture on the anterior part of the body in the female and the absence of yellow maculations on the mesosoma in the male (Gupta & Jonathan 2003). Male specimens examined in this study conform to C. c. quadrifasciata but females, with white vestiture on the anterior part of the body, resemble the nominotypical subspecies. Without being able to resolve this discrepancy, we avoid the use of subspecies herein.

One of the females of this study bear phoretic mites (Fig. 27B).
