Figs 1, 2View FIGURES 1, 2; Map 1

Myrmecobius luederwaldti Mello-Leitão, 1923: 524  (three ♀ syntypes from Ipiranga , São Paulo, Brazil, deposited in the Museu de Zoologia, São Paulo), not re-examined. 

Attacobius luederwaldti Mello-Leitão, 1925: 455  ; Platnick & Baptista, 1995: 7, figs 9–11; Bonaldo & Brescovit, 2005: 54, figs 24–37.

Diagnosis. Males of A. luederwaldti  are similar to those of A. attarum  by the RTA with three lobes and by the large, curved retrolateral cymbial process ( Bonaldo & Brescovit 1998: figs 12¯13), differing by the large, retrobasally curved cymbial transversal process and by the tegulum with a field of small tegumental papillae at the embolar base ( Figs 1View FIGURES 1, 2 ¯2).

Description. Male ( IBSP 91464). Carapace pale yellow, cephalic region grey with central discontinuous dark grey line, median eye area with black spot divided by wide longitudinal gap; chelicerae and fangs dark yellow; endites pale yellow with white apex, without conspicuous brown pit on basal inner margin; labium orange; sternum pale yellow with brown margins; legs pale yellow, distal portion of metatarsus black; abdomen pale yellow. Total length 3.33. Carapace 1.69 long, 1.38 wide, 0.73 high. Clypeus 0.15 high. Eye diameters and interdistances: AME 0.09, ALE 0.07, PME 0.06, PLE 0.05; AME –AME 0.25, AME –ALE 0.03, PME –PME 0.12, PME –PLE 0.04, ALE –PLE contiguous. MOQ length: 0.18, front width: 0.25, back width: 0.24. Chelicerae 0.50 long, with 3 promarginal and 2 retromarginal teeth. Sternum 0.89 long, 0.87 wide. Abdomen 1.64 long, 1.04 wide. Leg measurements: I: femur 1.63/ patella 0.64/ tibia 1.47/ metatarsus 1.39/ tarsus 1.12/ total 6.25. II: 1.63/ 0.56/ 1.40/ 1.41/ 1.12/ 6.12. III: 1.52/ 0.56/ 1.28/ 1.45/ 1.15/ 5.96.

II: femur d1-1-0, p0, r0, v0; tibia d0, p0, r0, v0-2-2; metatarsus d0, p0, r0, v2-2 -0. III: femur d1-1-0, p0, r0, v0; tibia d0, p0, r0, v0; metatarsus d0, p0, r0, v2- 2 -0. IV: femur d1-1-0, p0, r0, v0; tibia d0, p0, r0, v0; metatarsus d0, p0, r0, v0-2-0. Palp: RTA with three lobes; apical spur with a broad lamelliform base, arising sub-apically from ventral lobe; median lobe sclerotized; dorsal lobe finger-shaped, oriented apically; cymbial prolateral process large, fused to cymbial transversal process; cymbial transversal process visible in ventral view; cymbial retrodorsal process strongly projected and excavated; cymbial retrolateral tubercle large, rounded; both prolateral tegular keel and ventral tegular keel absent; tegular retrolateral groove present; proximal extension of median apophysis long; median extension of median apophysis entire, smooth; distal extension of median apophysis apically projected ( Figs 1, 2View FIGURES 1, 2).
