Etymology. Name from the Tupi-Guarani ‘ pinima ’, an adjective meaning spotted with different colors on the body; noun in apposition.
Diagnosis. Speocera pinima sp. nov. differs from S. babau sp. nov. and S. piquira sp. nov. by the male having pentagonal SCI in the embolus and slender conductor in the palp (Figs. 1E–F; 3E–F; 4A–B)—while in the other two species it is elongated, and having a preeminent conductor; figs 7E, 12E. The female of Speocera pinima sp. nov. resemble those of S. babau sp. nov. by its long afferent spermathecae and elongated lateral plates (Figs 5D–F; 6D) but differs by oval spermathecae (Fig. 5E–F) and tapered and curved terminal depression (Figs. 5D; 6D) in the genitalia.
Description. Male (Holotype). Total length 0.85. Carapace length 0.35, ovoid; narrowing gradually anteriorly, yellow with border black striated, flat pars cephalic, fovea absent (Fig. 1A). Clypeus length 0.02, with a pair of long bristles (Fig. 2A). Eyes with black border; PME oval; ALE and PLE rounded, ranging from opalescent or white (Fig. 2A). Chelicerae light yellow, promargin with seven teeth, attached to a very long lamina, retromargin with two small teeth (Fig. 2C). Sternum yellow. Endites yellow, with large serrula with more than 15 denticles, distal macrosetae paired and crosier-like, many multifid macrosetae present (Fig. 2B, arrow). Labium yellow, sulcated distally (Fig. 2B). Legs gray; formula 4123; total length: I 1.4; II 1.2; III 1.0; IV 1.7. Male palp: palpal femur length 0.02; palpal tibia enlarged basally, with four dorsal trichobothria (Fig. 3B); cymbium conical distally, bearing subdistal pair of modified setae and a projected and bifid tarsal organ (Figs 2F; 3A); bulb spherical (Figs 1B – D; 3C – D); conductor shorter than SCI (Figs 1E – F; 3E – F; 4A – B); embolus with truncated SCII, conical SCIII and large and with three short projections in the SCIV (Figs 1E – F; 3E – F). Abdomen length 0.45, oval; uniformly grayish (Fig. 1A). Two epiandrous spigots, with large, conic and striated base (Fig. 2D). Colulus triangular with six bristles (Fig. 2E).
Female (Paratype, IBSP 188899). Coloration as in male, except for darker carapace on the edges and orange chelicerae, and gray abdomen on the posterior edge (Fig. 5A – C). Total length: 0.81; carapace length: 0.4; Carapace as in male, light yellow pattern (Fig. 5A). Pedipalp without claw, with conical tip (Fig. 6A) and subdistal bifid tarsal organ. Clypeus: 0.02 diameter, with setae as in male. Eyes, chelicerae, sternum, endites and labium (Fig. 4C – D) as in male. Legs as in male; formula 4123, total length: I 1.4; II 1.2; III 1.0; IV 1.7. Abdomen length 0.42. Colulus triangular with six bristles (Fig. 6B). Genitalia externally with long and curved lateral plates, large ventral plate and terminal depression inconspicuous (Figs 5B – D; 6C – D); internally with paired and contiguous spermathecae, and afferent spermathecae with distal narrow area (Fig. 5E–F).
Variation. 10 ♂♂: total length 0.75 – 0.9; carapace 0.27 – 0.43; femur I 0.26 – 0.44. 10 ♀♀: total length 0.76 – 0.86; carapace 0.31 – 0.44; femur I 0.23 – 0.35.
Distribution. Known only from iron caves in the Serra Norte (municipality of Paraupebas) and Serra Leste (municipality of Curionópolis) in the region of the Carajás, Pará state, northern Brazil in a range of approximately 60 km (Fig. 19B, E).
