BRAZIL: Pará: Almeirim: 1 ♂ (MPEG 21144); 1 ♀ (MPEG 21143); 1 ♂ (1.013306°S, 52.836333°W; 62 m) (MPEG 21142); 1 ♀ (1.042417°S, 52.826917°W; 80 m) (MPEG 21141), 1 ♀ (1.034667°S, 52.842556°W; 98 m) (MPEG 21140); 1 ♀ (1.034833°S, 52.838806°W; 102 m) (MPEG 21139); 1 ♂ (1.030333°S, 52.917389°W; 148 m) (MPEG 21138); 1 ♀ (1.029°S, 52.921944°W; 141 m) (MPEG 21137); 1 ♂ 7 ♀ (MPEG 21136), all collected in VI.2013, Filipe França.
Etymology. The specific name is in honor of Filipe França, who collected all the specimens of this species examined in this study and provided information about its biology.
Diagnosis. The males of Kalcerrytus filipi sp. nov. are similar to those of K. amapari Galiano, K. edwardsi Ruiz & Brescovit, K. mberuguarus Ruiz & Brescovit, K. merreti Galiano and K. leonardi sp. nov. by having a short, stout RTA (Figs 15–16, 19), but can be distinguished from K. amapari by the triangular RTA (rounded in K. amapari) and from K. merreti and K. leonardi sp. nov. by the smooth embolar base (Figs 14, 18) (striated in those two). They can be distinguished from those of K. edwardsi and K. mberuguarus by the slender, smooth embolus (the embolus has a retrolateral projection in K. mberuguarus and a distal expansion in K. edwardsi). The females are similar to that K. edwardsi for having a projection on the copulatory opening (Figs 17, 20; compare with Ruiz & Brescovit 2003: fig. 4), but can be distinguished for having the copulatory openings obliquely placed on the epigynal plate (transverse in K. edwardsi).

Distribution. Known only from type locality.
Natural history. Some specimens were found hunting on logs and exposed roots. The male paratype was collected on a leaf hanging at 25 cm from the ground. Female MPEG 21141 was collected at 50 cm from the ground, while preying on a fly.
