Figs 23–32 View FIGURES 23 – 24 View FIGURES 25 – 28 View FIGURES 29 – 32

Type material. Male holotype ( MPEG 21135) from Acampamento Mutum (1.612417ºS, 56.194222ºW), Juruti, Pará, Brazil, R.F. Saturnino, 20.08.2011. Female paratype ( MPEG 21134) from Sítio Barroso (2.461583ºS, 56.003222ºW), Juruti, Pará, Brazil, D.F. Candiani & N.F. Lo-Man-Hung, 15–22.XI.2007.

Etymology. The specific name is dedicated to the fiction character of “The Big Bang Theory” TV show, Dr. Leonard Hofstadter.

Diagnosis. The males of Kalcerrytus leonardi sp. nov. are similar to those of K. amapari Galiano , K. edwardsi Ruiz & Brescovit , K. mberuguarus Ruiz & Brescovit , K. merreti Galiano and K. filipi sp. nov. by having a short, stout RTA ( Figs 26–27 View FIGURES 25 – 28 , 30 View FIGURES 29 – 32 ). They can be distinguished from that of K. amapari for the triangular RTA (rounded in that species) and from K. edwardsi , K. mberuguarus and K. filipi for the striated embolar base ( Figs 25 View FIGURES 25 – 28 , 29 View FIGURES 29 – 32 ) (smooth in those three). They can be distinguished from those of K. merreti by the developed ramus on the prolateral side of the embolus ( Figs 25 View FIGURES 25 – 28 , 29 View FIGURES 29 – 32 ) (only a low tubercle in K. merreti ; see Galiano 2000: fig. 3). The females can be distinguished from those of other species by having S-shaped copulatory ducts in the epigyne ( Fig. 32 View FIGURES 29 – 32 ) (longer and more convoluted in remaining species).

Palp ( Figs 25–27 View FIGURES 25 – 28 , 29–30 View FIGURES 29 – 32 ): femur with a sub-conical distal proventral tubercle; RTA sub-triangular; embolic base developed, embolus with a prolateral projection. Color in alcohol: carapace and abdomen as in the genus (see Galiano 2000; Edwards 2015), with a tuft of white scales between AME and ALE, a pair of stripes of white scales extending from under PME to the posterior portion of carapace; femur, patella and tibia I light brown (median tibia lighter), metatarsus and tarsus yellow; proximal femur II yellow, distal light brown, patella and tibia II light brown (median tibia lighter), metatarsus and tarsus lighter; legs III and IV yellow with brown pattern, lighter than I and II ( Fig. 23 View FIGURES 23 – 24 ).

Female (paratype, MPEG 21134). Total length: 7.58. Carapace 3.74 long, 2.59 wide, 1.92 high. Ocular quadrangle 1.82 long. Anterior eye row 2.40 wide and posterior 2.21 wide. Chelicera as in male. Length of femur: I 1.92, II 1.83, III 2.52, IV 2.19; patella + tibia: I 2.43, II 2.22, III 2.49, IV 2.28; metatarsus + tarsus: I 1.05, II 1.59, III 2.19, IV 2.40. Leg formula: 3421. Leg spination: femur I d1-1-1, p2di; II d1-1-1, p2di, r0-1-1; III d1-1-1, p0-1- 2, r1di; IV d1-1-1, p0, r1di; patella I 0; II r1; III p1, r1; IV p1, r1; tibia I–II d0, p1-1-1, r0, v2-1 -2; III d0, p1-1-1, r1- 1-1, v0-1-2; IV d0, p0-1-1, r1-1-1, v0-1-2; metatarsus I v2-2; II v2-2; III d1p-1r-1r-2di, p0-1-1, r0-1-1, v0-2-2; IV d2-2-2, p1-0-1, r0-1-1, v2 di. Epigyne ( Figs 28 View FIGURES 25 – 28 , 31–32 View FIGURES 29 – 32 ): posterior edge with two lobes, copulatory openings posteriorly placed, U-shaped. Color in alcohol: carapace and abdomen as in the genus (see Galiano 2000; Edwards 2015); proximal femur I brown, distal yellow, legs II to IV yellow ( Fig. 24 View FIGURES 23 – 24 ).

Distribution. Known only from the type locality.

Natural history. The female paratype has been collected with a pitfall trap, confirming the generic habit to live on the ground.
