Etymology. The specific name refers to Aragog, a spider capable of communicating with humans and a lover of human flesh, from the literary classic "Harry Potter and the Chamber of Secrets", by J.K. Rowling. Diagnosis. Ochyrocera aragogue resembles O. laracna by the yellowish green body color pattern (Fig. 10 A-B ) and by the short cymbial apophysis with two distal cuspules on projections (Fig. 10 C-D , 11F), a unique character for both these Neotropical species. The male can be distinguished from O. laracna by the palp with a sinuous distal area of embolus without laminar spur (Figs 10 C-D , 11 A-B , D). The female has an enlarged distal area of spermathecae and pore plates at the spermathecae base (Fig. 10 E-F ). Figure 10.

Abbreviations: NUE = neck of uterus externus, PP = pore-plate, SP = spermathecae. Scale bars: 0.5 mm (A, B); 0.7 mm (C, D); 500 µm (E, F). Description. Male (holotype). Total length 2.3. Carapace length 0.7, ovoid; narrowing gradually anteriorly, with yellowish-green pattern, pars cephalica flat, fovea not visible (Fig. 10A). Clypeus length 0.7, curved foward. Eyes: PME elongated oval; ALE and PLE rounded. Chelicerae light yellow, promargin with seven teeth, attached to long lamina (Fig. 12A); retromargin without teeth. Sternum light yellow gray. Endites dark yellow suffused. Legs light yellow, formula 1423, total length I 7.0; II 5.9; III 4.1; IV 6.5. Male palp: palpal femur length 0.4; palpal tibia short, as long as cymbium; cymbial apophysis short, bearing two short distal cuspules at tip, in different heights, retrolateral long hair on non-projected base, next to the tarsal organ; with four basal setae (Fig. 11C, E-F ); cymbial prolateral extension almost squared; embolus elongated, enlarged at base and subapically twisted (Figs 10 C-D , 11A). Abdomen length 1.3, oval, uniformly green-purplish color (Fig. 9A). Six epiandrous spigots, with short base (Fig. 12B). Figure 11.

Pedipalp without claw, with conical tip and subdistal tarsal organ (Fig. 12 E-F ). Clypeus 0.68 diameter. Eyes, chelicerae, sternum, endites (Fig. 12D) and labium as in male. Legs as in male, formula 4123, total length I 6.3; II 4.7; III 3.6 IV 4.3. Abdomen length 0.96, globular (Fig. 10B). Colulus triangular, with approximately 10 bristles (Fig. 12C). Internal genitalia weakly sclerotized, spermathecae tubular, slender in basal area and curved and thickened at distal area. Uterus externus shorter than spermathecae, internally with no visible chambers, ending in truncated neck. Oval pore-plates at the base of spermathecae, with approximately 25-30 glandular ducts (Fig. 10 E-F ). Distribution. Recorded exclusively from caves in the Carajas region, state of Para , northern Brazil (Fig. 19B).
