Kalcerrytus leonardi  sp. nov.

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

Type material. Male holotype ( MPEGAbout MPEG 21135) from Acampamento Mutum (1.612417 ºS, 56.194222 ºW), Juruti, Pará, Brazil, R.F. Saturnino, 20.08. 2011. Female paratype ( MPEGAbout MPEG 21134) from Sítio Barroso (2.461583 ºS, 56.003222 ºW), 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 –27View FIGURES 25 – 28, 30View 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 25View FIGURES 25 – 28, 29View 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 25View FIGURES 25 – 28, 29View 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. 32View FIGURES 29 – 32) (longer and more convoluted in remaining species).

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.
