Exechocentrus

Exechocentrus is a genus of Madagascan orb-weaver spiders (family Araneidae) first described by Eugène Simon in 1889. They are bolas-using spiders, capturing their prey with one or more sticky drops at the end of a single line of silk rather than in a web.

==Description== Males of the genus are unknown. Females can be distinguished from all other known members of the family Araneidae by the spine-like projections on the cephalothorax. One is centrally placed and extends forwards; three are more-or-less upright. The total body length is . The cephalothorax is yellowish-white with brown lines radiating from the fovea and is about as wide as it is long. The legs are pale yellowish-white with dark brown markings. The abdomen is off white and almost heart-shaped from above. The epigyne has a strongly hardened (sclerotized) lip. The spermathecae are large and ovoid, with short narrow copulatory ducts.
