Comment: The monophylum herein labelled ‘clade A’ and described as the new subfamily Libitiinae , includes four terminals of our analysis, which may be extrapolated to ten species. Libitia bipunctata Sørensen, 1932 and * Libitia cordata ( Gervais, 1844) here represent the genus Libitia Simon, 1879 , which has two further species, all four of them from Colombia ( Medrano et al., 2020). * Ambatoiella vigilans Mello-Leitão, 1943 stands for the genus Ambatoiella Mello-Leitão, 1943 , which has a second species, both occurring in Ecuador ( Medrano & Kury, 2017). * Oligovonones brunneus Caporiacco, 1951 here represents the genus Oligovonones Caporiacco, 1951 , which has further three species, all found in Venezuela ( González-Sponga, 1992). All three genera in their current configurations may, for the present purposes, be treated as probable monophyletic units.

Diagnosis: Small animals with short legs. DS alphatype with large coda. Fe IV curved and shorter than DS length. DS flat in lateral view, areas of mesotergum without any armature. Coxa IV entirely visible in dorsal view, convex and short (0.3× DS length in dorsal view). Leg I with five tarsomeres; leg III with five to six tarsomeres. Penis with two pairs of MS-A. Yellow spots mostly reduced to small dots in laterals of scutal grooves, extending medially in Libitia .

Type genus: Libitia Simon, 1879 .

Included genera: Ambatoiella Mello - Leitão, 1943; Libitia Simon, 1879; and Oligovonones Caporiacco, 1951.

Distribution: Northern Andes ( Fig. 7 ).
