Diagnosis (after Deeleman-Reinhold 2001 ). Spiders of the genus Medmassa can be recognised from other Castianeirinae by the presence of a male palpal RTA that is often forked, the U-shaped sperm duct that lacks an additional loop, and the cymbium with a deep ventral furrow distally. The female epigyne has the copulatory openings located anteriorly and simple large round or oval spermathecae not divided into two distinct regions. Both sexes bear 7–10 pairs of ventral spines on the anterior tibiae, a character shared only with the ant-mimicking genus Pranburia Deeleman-Reinhold, 1992 .
