    Abstract

    The immature stages and male adult of Afrochlus harrisoni Freeman are described for the first time, from the type locality, a granite outcrop in Zimbabwe. A phylogenetic position within the subfamily Podonominae as sister to South African-western/central Australian genus Archaeochlus Brundin, suggested in 1966 by Brundin from the adult female alone, is confirmed by cladistic analysis of all life history stages combined. Within the Podonominae, the tribes Boreochlini and Podonomini erected by Brundin are monophyletic only if Trichotanypus Kieffer is transferred from the former to the latter. Little or none of the structure provided by the combined evidence from all stages is retrieved by cladistic analyses of characters derived solely from the adult stage. The implications of erection of monotypic genera for adult-only taxa are discussed.
