Etymology. The species name refers to the red coloration of the holotype.

Diagnosis. Males of A. verrucosus sp. nov. can be diagnosed by the elongated tibia of the male palp in combination with the concave shape of the MA and the shape of RTA ( Figs 1, 2, 7 View FIGURES 1 – 7 , 8, 11 View FIGURES 8 – 14 ). Females can be separated by the shape of H and ET ( Figs 3 View FIGURES 1 – 7 , 13 View FIGURES 8 – 14 ).

Description. Male: Total length: 6.3; prosoma length: 3.1, width: 2.9. Leg I: femur 5.0, patella 1.5, tibia 5.0, metatarsus 3.5, tarsus 1.5. Leg formula 1243. Leg I femur with mounds of fine setae (sometimes with a spine), claw tufts present and dense. Prosoma dark red brown, apex lighter. Posterior portions of prosoma rounded, anterior eye region projected beyond the clypeus. Eyes not on tubercles, ALE>PLE>PME>AME, both rows recurved, distance between PMEs larger that distance between AME. ALE project slightly forwards. Opisthosoma dark brown with white spots, apex with dark triangular markings. Shape of opisthosoma oval, center broadest, cololus absent ( Fig 14 View FIGURES 8 – 14 ). Palp: tibia elongated, cymbium and tegulum oval, cymbium with trichobothria. E tapering, short. MA present, leaf-like, C absent ( Figs 1, 2, 7 View FIGURES 1 – 7 , 8–11 View FIGURES 8 – 14 ). However, note the presence of a structure of unknown function adjunct to E that is highlighted “C?” in Fig 11 View FIGURES 8 – 14 .

Female: Total length: 11.0; prosoma length: 4.5, width: 4.5. Leg I: femur 5.5, patella 1.5, tibia 5.0, metatarsus 3.1, tarsus 1.5. In general similar to male. Females differ in less prominent white spots and prominent triangular marking on the grey dorsum of opisthosoma. Epigynum with hood and ET; S kidney shaped, CO laterally, below ET ( Figs 3 View FIGURES 1 – 7 , 13 View FIGURES 8 – 14 ).
