[1][2] Cladomelea species, including C. debeeri, are "bolas spiders" – adult females capture their prey by using one or more sticky drops on the end of a line which they swing,[2] usually catching male moths attracted by the release of an analogue of the attractant sex pheromone produced by the female moth.

The head region had four tubercules: a short one at the front, then a longer one, and then a pair of shorter ones.

The abdomen was creamish yellow, shaped like a backward pointing triangle with five tubercules at each front corner and six at the back.

[1] Cladomelea species are bolas spiders, and although the genus was not included in two relevant molecular phylogenetic studies in 2014 and 2020,[4][5] would be expected to be part of the "mastophorines", placed in the subfamily Cyrtarachninae s.l.

This was made up of two or three increasingly shorter silk threads each ending in a sticky droplet about 2–3 mm in diameter.
