Xin, Yafei, Jiang, Tongyao, Yao, Zhiyuan & Li, Shuqiang, 2021, Three new species of the extinct spider genus Furcembolus (Araneae: Pacullidae) from Late Cretaceous Burmese amber, Zootaxa 4984 (1), pp. 258-273 : 259

Genus † Furcembolus Wunderlich, 2008

Type species: Furcembolus andersoni Wunderlich, 2008

Diagnosis. The genus is characterized by the presence of a small bulb; embolus with or without an obvious bifurcation in the middle. Carapace of males with obvious wrinkles, no apophysis in known species, cephalic part of carapace clearly the highest. Metatarsi are ca. 2–3 times longer than tarsi (modified from Wunderlich 2008, 2015, 2017).

Remarks. † Furcembolus was established by Wunderlich in 2008, placed in the fossil family † Eopsilodercidae Wunderlich, 2008 , but Wunderlich wasn’t sure about their relationships. † Praeterpaculla Wunderlich, 2015 was erected by Wunderlich under the family Tetrablemmidae with five new species. After studying further specimens, the genus † Praeterpaculla was regarded as a junior synonym of † Furcembolus , and † Furcembolus turned out to be a taxon of Pacullinae, Tetrablemmidae ( Wunderlich 2017) . After the restoration of family status of Pacullidae ( Wheeler et al. 2017) , Magalhaes et al. (2020) proposed that † Furcembolus should be listed under Pacullidae . At present, † Furcembolus is the only genus of extinct Pacullidae , including nine known species and three new species described in this paper.
