The Palpimanidae, or brush-footed spiders, is a minute family with 144 species placed in 18 genera [WSC, 2017]. The family has a rather unusual distribution: the entire Africa and Neotropical Region (north to Cuba) and a vast part of Eurasia (from the Iberian Peninsula to Malaysia) [Platnick, 2014]. All species are restricted to the subtropical and tropical regions. The family is currently divided into three subfamilies: Chediminae Simon, 1893, Palpimaninae Thorell, 1870, and Otiothopinae Platnick, 1975 [Jocqué, DippenaarSchoeman, 2006]. The latter subfamily (with a few exceptions due to misplacement) is restricted to the Neotropics and relatively well investigated; while the two former subfamilies are restricted to the Old World and both have been poorly studied. The nominative type genus of the Chediminae, the monotypic Chedima Simon, 1873, has been never properly described. There are only three published figures devoted to this genus and demonstrating the habitus and the eye group [Simon 1873, 1893]. The copulatory organs of Chedima have been never illustrated. While studying palpimanids in the Senckenberg Museum (Frankfurt-am-Main) we found two specimens that match the description of Chedima purpurea Simon, 1873 in respect to their habitus, eye pattern and some other characters. Both specimens were collected close to the type locality of C. purpurea. Unfortunately, the types of this species are currently unavailable, ABSTRACT. A monotypic Chedima Simon, 1873, the nominative genus of the subfamily Chediminae, and its type species C. purpurea Simon, 1873, are redescribed. The copulatory organs of C. purpurea are illustrated for the first time. The morphological study of the genus reveals several features previously unknown in the Palpimanidae, or in the Entelegynae, or even in the entire order Aranei: 1) the presence of a large copulatory opening (atrium) inside the epigastral furrow; 2) part of the female copulatory apparatus is located in the postgastrum; 3) the presence of a permanent mating plug; and 4) the mating plug represents a part of the female copulatory organ.

A redescription of Chedima purpurea Simon, 1873, with notes on the unique copulative stopper mechanism in females (Aranei: Palpimanidae)
