Type species. Jipai longevus sp. nov., by monotypy.

Diagnosis. In common with the following eleven Neotropical hubbardiid genera, Jipai gen. nov. possesses a female flagellum comprising four flagellomeres and three annuli ( Figs. 5D–F , 6D–F ): Adisomus Cokendolpher & Reddell, 2000 ; Calima Moreno-González & Villarreal, 2012 ; Cangazomus Pinto-da-Rocha et al. 2016; Colombiazomus Armas & Delgado-Santa, 2012 ; Hansenochrus Reddell & Cokendolpher, 1995 ; Mayazomus Reddell & Cokendolpher, 1995 ; Naderiore Pinto-da-Rocha et al. 2016; Piaroa Villarreal et al. 2008 ; Rowlandius Reddell & Cokendolpher, 1995 ; Tayos Reddell & Cokendolpher, 1995 ; Wayuuzomus Armas & Colmenares, 2006 . However, these genera may be separated as follows. The presence of two pairs of lobes, median lobes (ML) and lateral lobes (LL), in the spermatheca ( Fig. 4E ) separates Jipai gen. nov. from Adisomus , Calima , Piaroa , and Tayos , each of which possess a single pair (LL), whereas the ML being significantly longer than the LL separates Jipai gen. nov. ( Fig. 4E ) from some species of Hansenochrus , Rowlandius , and Wayuuzomus , in which the ML are similar in length to the LL, and from Cangazomus , Colombiazomus , Naderiore and some species of Hansenochrus and Rowlandius , in which the ML are shorter than the LL. Additionally, the presence of more than one pair of setae on opisthosomal tergite II separates Jipai gen. nov. ( Fig. 4A ) from all the abovementioned genera, except some species of Mayazomus , which only possess a single pair.

Jipai gen. nov. most closely resembles Mayazomus , from which it can be distinguished by the linear ML of the spermatheca ( Fig. 4E ), six setae (Dm, Dl 1, and Dl 2) on opisthosomal tergite II ( Fig. 4A ), and the male pedipalp with a slender femur lacking setiferous tubercles distally, the patella not curved ventrally, and a ventral apophysis absent on the tibia ( Fig. 3A ). In Mayazomus , the ML of the spermatheca are curved, four (rarely five) setae (Dm and Dl 1) are present on tergite II, and the male pedipalp exhibits a robust femur with setiferous tubercles distally, the patella markedly curved ventrally, and a ventral apophysis present on the tibia.

Etymology. The generic name, masculine in gender, is a noun for soil or ground in Kurripako, a language of the Arawak linguistic family, spoken in parts of the Amazon in Brazil, Colombia and Venezuela. It refers to the substrate in which schizomids are commonly found.
