Attacobius verhaaghi Bonaldo & Brescovit, 1998: 170, figs 14–17 (♀ holotype from Chapada do Araripe, 07°10'S, 39°30'W, 10 km from Crato, Ceará State, Brazil, 30.I.1995, M. Verhaagh & D. Frey leg., MCN 26589), re-examined.
Attacobius verhaagui; Bonaldo & Brescovit, 2005: 36, 38, 48 (lapsus).
Diagnosis. Males of A. verhaaghi are similar to those of A. lamellatus Bonaldo & Brescovit by the presence of an additional, median lobe on the RTA, the finger-shaped dorsal lobe, and the median sector of the median apophysis composed of two smooth pieces (Bonaldo & Brescovit 2005: figs 4, 5). They differ by the thin, almost unsclerotized median lobe, and by the cymbial transverse process being larger and visible in ventral view (Figs 7, 8).

Carapace yellow, anterior median eye area with black spot divided by longitudinal gap; chelicerae dark yellow with fangs brown; endites pale yellow with white apex, labium pale yellow; sternum pale yellow with brown margins; legs: femur and patella yellow, tibiae, metatarsus and tarsus pale orange; abdomen pale yellow. Total length 4.12. Carapace 1.72 long, 1.40 wide, 0.49 high. Clypeus 0.16 high. Eye diameters and interdistances: AME 0.11, ALE 0.07, PME 0.95, PLE 0.79; AME–AME 0.08, AME–ALE contiguous, PME–PME 0.14, PME–PLE 0.07, ALE–PLE contiguous. MOQ length: 0.28, front width: 0.23, back width: 0.27. Chelicerae 0.57 long, with 3 promarginal and 2 retromarginal teeth. Sternum 1.01 long, 1.00 wide. Abdomen 2.27 long, 1.37 wide.

II: femur d1-1-0, p0, r0, v0; tibia d0, p0, r0, v3-2 -2; metatarsus d0, p0, r0, v2-2 -0. III: femur d1-1-0, p0, r0, v0; tibia d0, p0, r0, v0; metatarsus d0, p0, r0, v0. IV: femur d1-1-0, p0, r0, v0; tibia d0, p0, r0, v0; metatarsus d0, p0, r0, v0. Palp: RTA with three lobes, ventral lobe large; apical spur sclerotized, with broad base arising sub-apically from ventral lobe, dorsal lobe finger-shaped, oriented apically, without sub-apical digitiform process; cymbial prolateral process projected, excavated, separated from cymbial transversal process; cymbial transversal process long, gently curved retro-apically, without basal prong; cymbial retrolateral tubercle sub-quadrangular in retrolateral view; cymbial retrodorsal process small, excavated, directed basally; both prolateral tegular keel and ventral tegular keel present, small, contiguous; tegular retrolateral groove present, wide; distal extension of median apophysis protruded apically; median extension of median apophysis smooth, composed of two pieces, proximal extension of median apophysis long (figs 7, 8).
