Type material: Holotype: male from Fazenda Retiro Novo, Pantanal do Poconé, Nossa Senhora do Livramento , Mato Grosso, Brazil [16°15’ – 17°54’S, 56°36’ – 57°56’W], January 2004 – March 2005, L.D. Battirola ( IBSP 120581 ). Paratype: 1 female, same data as holotype ( IBSP 120592 ) .

Additional material examined. BRASIL: Amazonas: 1 male, Manaus, Rio Tarumã-Mirim , 1979–1980, J. Adis ( IBSP 120596 ); Mato Grosso: 4 males, Nossa Senhora do Livramento, Pantanal do Poconé, Fazenda Retiro Novo , January 2004 – March 2005, L.D. Battirola ( IBSP 120579, 120588, 120590, 156552 ).

Etymology. The specific name is composed of “hetero” (different in Greek) and “picta” (painted in Latin) and refers to the color pattern of the species, which is different from that found in the species described above. Adjective.

Diagnosis. Males of this species can be distinguished from those of the remaining species of the genus by having the ventral branch of the RTA more developed than the dorsal one in the male palp ( Figs 17–19). The females of K. heteropicta sp. nov. resemble those of K. extratheca sp. nov. by the long copulation ducts and bulbous extra spermathecae, but can be distinguished by the copulation openings, which are connected posteriorly by a rim ( Fig. 21).

Description. Male holotype: Total length: 3.35. Carapace dark brown, 1.50 long, 1.00 wide, 0.50 high. Ocular quadrangle black, 0.77 long. Anterior eye row 0.85 wide and posterior 0.85 wide. Clypeus covered with white scales. Chelicera dark brown. Endite with no lateral projection, dark brown. Labium dark brown; sternum yellow. Palp light brown, with a bifid RTA, ventral branch more developed than the dorsal one, tegulum projected posteriorly and embolus slightly long, arising proximally on the prolateral side ( Figs 17– 20). Legs 1432; I dark brown, II–IV yellow; distal femora and patellae II–IV with dark brown marks; leg I robust with reduced spines. Length of femur: I 0.87, II 0.60, III 0.70, IV 0.85; patella + tibia: I 1.25, II 0.70, III 0.85, IV 0.95; metatarsus + tarsus: I 0.70, II 0.57, III 0.72, IV 0.80. Spination: femur I 0, II=III d1-1-1, p1di, IV d1-1-1, r1di; tibia I v1r(small)-0-1p(small), II v1r-1r-0, III p1di, r1di, IV p1di; metatarsus I v2-2, II v1r-2, III p1di, r1di, IV r1di, v1di.

Chelicera dark brown. Endite and labium light brown. Palp and sternum yellow. Legs 4132, yellow, with barely conspicuous dark brown marks laterally. Length of femur: I 0.65, II 0.60, III 0.60, IV 0.85; patella + tibia: I 0.85, II 0.65, III 0.65, IV 0.95; metatarsus + tarsus: I 0.57, II 0.50, III 0.75, IV 0.85.
