Figs 23–32

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 , 30 ). 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 , 29 ) (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 , 29 ) (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 ) (longer and more convoluted in remaining species).

Epigyne ( Figs 28 , 31–32 ): 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 ).

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.
