Genus Cybaeodamus Mello-Leitão, 1938

Hyltoniella Mello-Leitão, 1940 – Jocqué 1991: 49 (in synonymy).

Valcheta Mello-Leitão, 1940 – Jocqué 1991: 49 (in synonymy).

Type species

Cybaeodamus ornatus Mello-Leitão, 1938; gender masculine.

Diagnosis

Cybaeodamus can be recognized by the combination of following characters: both sexes have the chelicerae densely covered with setae (Fig. 14G), and the coxae IV are positioned close to each other, sometimes touching in males (Figs 1B–C, 7C, 10B, 14C, I). Additionally, males are recognized by having at least two tegular apophyses – a median apophysis and a terminal, sclerotized conductor-like appendage – and are further characterized by a field of densely packed modified setae on the venter of the abdomen (Figs 3B–F, 10K–L, 14C–H; see also Lise et al. 2009: figs 13–14, 35; and Andía & Grismado 2015: fig. 4b–c). Females are distinguished by the epigyne with strongly sclerotized areas on both sides and anteriorly delimited by deep arches (Figs 6C, 9A–C).
