Langelurillus cedarbergensis

Langelurillus cedarbergensis is a small spider. The female has a cephalothorax that ranges in size between 2.6 and 2.7 mm (0.10 and 0.11 in) in length and 2.0 and 2.2 mm (0.079 and 0.087 in) in width. It has a carapace that Is high, dark brown and covered in dense grey-white hairs. It has a black eye field. The clypeus is low and orange. The chelicerae are light brown with a small visible tooth on the edge. The labium is brownish with pale tips. The abdomen is spherical, between 3.4 and 3.8 mm (0.13 and 0.15 in) long and typically 3.2 mm (0.13 in) wide. It is greyish beige on top with a light underside and has long spinnerets.^[7] The spider has short light brown legs. The epigyne is small with a notch to the rear and a wide pocket. The copulatory openings are also to the back of the epigyne leading to short seminal ducts.^[8] The spermathecae have a single chamber.^[9] The male has not been described.^[1]

It is the design of its copulatory organs that most distinguishes the spider from others in the genus. It most resembles Langelurillus namibicus but differs in that the copulatory openings are wide apart and the seminal ducts short.^[9]

Almost all, if not all, Langelurillus spiders are to be found in sub-Saharan Africa.^[10] Langelurillus cedarbergensis is endemic to South Africa.^[1] The holotype was discovered in 1985 in the Cedarberg Mountains, after which the species is named.^[9] It is a ground-dwelling spider that lives in fynbos environments.^[8]
