1C7F87D7FFCCFFD3FF78FD8F8F67F89F.taxon	etymology	Etymology. The specific epithet refers to the name of the river of the type locality and is a name in apposition from the Guaraní language “ hû ” that means “ black ”, and it was how this ethnic group called the Negro River because of the mighty river and the dark color of its water.	en	Cajade, Manuel, Hagopián, Damián, Rodrigues, Everton N.

Males of A. hum n. sp. resemble those of A. adami (Millidge, 1991) in having the lamella characteristica wider in the apex and with thorns distally (Fig. 9; Rodrigues et al. 2013), but differ in lacking a basal lobe in the lamella characteristica (present in A. adami) (Figs 1 A, 5 B, 5 D), presence of apical pocket of paracymbium (absent in A. adami) (Figs 1 A, 5 B), presence of posterior pocket of paracymbium (absent in A. adami) (Figs 1 A, 5 B), presence of dorsal tibial apophysis (absent in A. adami) (Figs 1 A, 1 E, 5 B), dorsal cymbial tubercle rugose and apically rounded (smooth and acute in A. adami) (Figs 1 B, 1 F, 5 C, 5 E), and ventral cymbial tubercle rugose, apically truncated and dentated (smooth and acute in A. adami) (Figs 1 B, 1 F, 5 C, 5 E). Females resemble those of A. adami (Millidge, 1991) in having oval epigynal slits (Fig. 420; Millidge 1991), but it differ in having the margins of the proximal part of the scape parallel (convex in A. adami) and presence of pit hook depression (absent in A. adami) (Figs 2 A, 7 B).

1C7F87D7FFCBFFDAFF78FBFE8A8BFB17.taxon	etymology	Etymology. The species epithet is the combination of the Latin noun “ unguis ” (claw) and the Latin adjective “ serratus ” (serrated) and refers to the shape of the dorsal tibial apophysis of the male palp and the denticles present on the retrolateral margin of it.	en	Cajade, Manuel, Hagopián, Damián, Rodrigues, Everton N.

1C7F87D7FFCBFFDAFF78FBFE8A8BFB17.taxon	diagnosis	Diagnosis. Males of A. unguiserrata n. sp. resemble those of A. straminicola (Millidge, 1991) in having a long pointed dorsal apophysis (Fig. 389; Millidge 1991) but can be distinguished from this latter species and all others of the genus by having a dorsal tibial apophysis claw-shaped with denticles on the retrolateral margin (Figs 3 A, 3 E, 6 B). Females differ from all South American species with the exception of A. propria (Fig. 400; Millidge 1991) by having a broad V-shaped proximal part of the scape and narrow lateral lobes, but can be distinguished from it and all others Agyneta by having two conspicuous elliptical processes (Figs 4 A – B, 7 D).	en	Cajade, Manuel, Hagopián, Damián, Rodrigues, Everton N.
