Etymology. The specific epithet is a patronym in honor of the memory of Andrés García, a Colombian arachnologist and a great friend who made significant contributions to the study of Opiliones in the Neotropical region.

Diagnosis. Males of Eutichurus andresgarcia sp. nov. are similar to those of E. tropicus (L. Koch, 1866) by having a conspicuous embolar prolateral process with a filiform embolus and an excavated RTA ( Bonaldo 1994: 150, figs 43–45; Figs 5A–C View FIGURE 5 , 6A–C View FIGURE 6 , 7A–C View FIGURE 7 ). They differ by the embolus inserted basally, a longer embolar prolateral process located basally in the embolus and the RTA with a distinctive stem inserted in oblique angle with to the tibia, while in E. tropicus it is perpendicular to the tibia and does not have a stem ( Bonaldo 1994: 150, figs 43– 45; Figs 5A–C View FIGURE 5 , 6A–C View FIGURE 6 ).

Palp: cymbium longer than length of tibia; tegulum elliptical, longer than wide, conductor hyaline, oblanceolate, leaf-shaped; embolus basally broad, inserted sub basally on the tegulum, with long, tapering prolateral process, apex of embolus wavy, with a laminar zone extending for more than half its length; spermatic ducts broad, running marginally along tegulum; median apophysis scythe-shaped; retrolateral tibial apophysis cuboid in appearance (ventral view), truncate and excavated ( Figs 5 View FIGURE 5 , 6 View FIGURE 6 ).
