Spintharinae Hentz, 1850

( Figs. 8 , 9 , 10 A)

The subfamily Spintharinae is conformed by the genera Chrosiothes Simon, 1894 ; Episinus Walckenaer , in Latreille, 1809; Moneta O. P.-Cambridge, 1870; Spintharus Hentz, 1850 ; Thwaitesia O. P.-Cambridge, 1881 and Stemmops O. P.-Cambridge, 1894. Unambiguous synapomorphies include (Agnarsson 2004): conductor huge and folded (Agnarsson 2004, fig. 46A–D; fig. 90F–G), cheliceral base thin (Agnarsson 2004, fig. 84C), colulus small or replaced by two setae (Agnarsson 2004, fig. 70A), tarsal comb bristles with dorsal margin notched (Agnarsson 2004, fig. 84E), web modified (Agnarsson 2004, fig. 97A), and outermost fiber of the egg sac loosely spun (Agnarsson 2004, fig. 88C).
