Agobardus Keyserling 1885

Genus Agobardus Keyserling, 1885

Small to medium sized spiders. Body is usually relatively robust, not elongate. Male cheek is strongly swollen in some species. Chelicera usually has two promarginal teeth and one bicuspid retromarginal tooth. Male chelicera of some species is relatively enlarged with modifications. Tibia and metatarsus of first leg usually have three pairs of ventral macrosetae each. Embolus usually coils for no more than one circle. Tegulum lacks proximal lobe. Epigynum has two circular areas of relatively transparent and flat integument framed by two spiral grooves, which is typical in euophryine jumping spiders and referred to here as the epigynal “window”. Window of epigynum is large or relatively small, with a median septum. Spermatheca is strongly swollen. Agobardus shows similar body form as Bythocrotus, Compsodecta and some species of Antillattus, but differs from them by the bicuspid retromarginal tooth on chelicera. It also differs from Bythocrotus by the absence of stout macrosetae on the male palpal tibia, and from most species of Compsodecta by the absence of additional apophysis on the male palpal tibia or patella besides the retrolateral tibial apophysis.

Eleven species and one subspecies have been reported from the Caribbean Islands (Platnick 2011). However, some species described from Cuba (Bryant 1940) appear to belong to Antillattus Bryant, 1943 based on their diagnostic drawings. Also, some species described as Siloca Simon, 1902 (Galiano 1963) from Cuba may actually belong to Agobardus. Five new species from the Dominican Republic are described here. Placement of these new species in Agobardus is supported by unpublished molecular data.
