Etymology. The specific name refers to the Meta Department in Colombia, where the type locality is situated; noun in apposition.

Diagnosis. Male of Eutichurus meta sp. nov. are similar to those of Eutichurus abiseo Bonaldo, 1994 in having a laminar, expanded embolus tip ( Figs 13A–C View FIGURE 13 , 14A–D View FIGURE 14 ; Bonaldo 1994: 149, figs 35–37; figs 13A–C, 14A–D). It differs from the previous species and from the other species of the genus in having a large and shovel-shaped retrolateral tibial apophysis, a well-developed and apically rounded process of the embolus with a prolateral notch on the apex, and a median apophysis with a very thin tip ( Figs 13A–C View FIGURE 13 , 14A–D View FIGURE 14 ).

Description. Male holotype (MPUJ_ENT0070582). Coloration in ethanol: carapace uniformly pale brown, darker on cephalic and ocular region, with thin, dark brown thoracic groove. Chelicerae with paturon light brown and fangs reddish brown. Endites and labium brown. Sternum pale brown. Legs: I–IV as carapace. Opisthosoma: light yellow, dorsally and ventrally covered with fine black setae, with a dense patch of black setae around the tracheal and lung spiracles. Spinnerets pale yellow. Tarsi I–IV with dense scopulae, and metatarsi III–IV with scarce scopulae. Measurements: total length 6.76, carapace length 2.79, width 2.56, height 1.45. Clypeus height 0.11. Eye diameters and interdistances: AME 0.26, ALE 0.18, PME 0.20, PLE 0.20; AME–AME 0.63, AME– ALE 0.59, AME–PME 0.58, PME–PME 0.67, PME–PLE 0.48, ALE–PLE 0.42. Chelicerae length 1.47, with four promarginal and four retromarginal teeth. Sternum length 1.67, width 1.29. Legs: I—femur 4.31/ patella 1.38/ tibia 4.35/ metatarsus 4.90/ tarsus 1.61/ total 16.55; II—4.27/ 1.36/ 4.38/ 4.57/ 1.74/ 16.32; III—3.52/ 1.18/ 3.01/ 3.16/ 1.30/ 12.17; IV—4.46/ 1.29/ 3.78/ 5.17/ 1.42/ 16.42. Opisthosoma length 3.96. Legs and palp macrosetae pattern: palpal femur d 1-0-1, tibia p 1-0-1. I—femur d 1-0-1, p 0-1d-1d, r 0-1d-1d; tibia v 2-1-2-2 (2-2-2), p 1-0-1d (0-1d-0), r 0-1d-0; metatarsus v 2-2- 1p. II=I. III—femur d 1-0-1r, p 0-1d-1d, r 0-1d-1d; tibia v 1p-2-2, p 1-1, r 1-1; metatarsus v 2-1p-2, d p1r1-p1r1-p1r1, p 0-0-1, r 0-0-1; IV—femur=III, tibia v 1p-2-1p, p and r=III, metatarsus v 2-2-2, p and r=III. Palp: retrolateral tibial apophysis large and shovel-shaped; cymbium long, nearly twice the length of the tibia; retrolateral process of the cymbium slightly projected; tegulum sub-rounded, longer than wide; conductor hyaline, long, and thin; embolus long, flattened, and very wide; inserted sub-medially on the tegulum, apically flattened and bifid; spermatic ducts wide and S-shaped in ventral view; median apophysis small and thin, curved towards the posterior side of the bulb ( Figs 13–14 View FIGURE 13 View FIGURE 14 ).
