Genus Antillattus Bryant, 1943

Medium sized spiders. Male chelicerae are usually elongate or enlarged with modifications such as projections on the front and/or ectal surface. Endites are usually enlarged distally. Chelicera usually has a fissident retromarginal tooth with more than two cusps or a unident retromarginal tooth (e.g. Antillattus applanatus). Embolus of the male palp is usually short with a simple curve. Epigynum has an obvious window with a median septum. Vulva usually has a pair of secondary spermathecae in addition to the primary spermathecae. Antillattus differs from Agobardus in the dentition of the female chelicera ( Agobardus has one bicuspid retromarginal tooth in female) and the presence of the secondary spermatheca in vulva ( Agobardus lacks secondary spermatheca). Although some species of Agobardus also have enlarged chelicerae in male, they usually lack a projection on the front or ectal surface of the chelicera as seen in Antillattus .

Only two species have been reported from Hispaniola (Bryant 1943; Platnick 2011). However, some species placed in Agobardus, Pensacola and Siloca may actually belong to Antillattus . The new species is placed in Antillattus mainly because unpublished molecular data indicates that it is closely related to the type species of Antillattus, A. gracilis Bryant, 1943 .
