Separated from Badumna by the strong presence of white setae on the body; the possession on the male palp of a large, prolaterally directed, basal tegular bulge.
Niche Spiders
Mattachiidae Dalmas, 1917
Type genus: Matachia Dalmas, 1917
(after Wolff et al. 2026): Matachiidae have the eyes arranged in two rows, occupying about two-thirds or more of the head width, without marked size differences between eyes. The anterior row is more or less straight and the posterior row is gently procurved (if viewed from frontal) with marked (about one eye diameter) distances between posterior eyes, and on each side the anterior lateral and posterior lateral eye are grouped closely together. Matachiidae are characterized by male pedipalps with a thin, rod-like embolus that lies in the fold of a large, strongly curved conductor originating at the baso-retrolateral side of the bulb and with a spiniform, sclerotized tip directed towards the distal cymbium. The epigyne is equipped with lateral teeth.
