Ground Sac Spiders

Orthobula Simon, 1897

Type species: Orthobula impressa Simon, 1897

Fauna Portal Genus Number: 792

(after Haddad et al. 2022): Orthobula shares with Capobula the large number of paired ventral spines on the anterior tibiae and metatarsi, and the absence of ventral cusps in both sexes. In somatic morphology, Afrotropical species of Orthobula have pits across the entire carapace surface, including along the midline, while absent along the midline in Capobula and some Asian species of Orthobula. Female Orthobula can be distinguished by the posteriorly positioned spermathecae (as opposed to laterally positioned in Capobula), while male Orthobula can be recognized by the considerably inflated palpal tegulum (only as wide as cymbium in Capobula), the narrow, finely coiled embolus (longer, uncoiled and retrolaterally directed in Capobula), and the absence of a patellar apophysis (present in Capobula).
