description: Yunga andresi sp. nov.
(Fig. 2A–D, 3)
Diagnosis. Style (Fig. 3C) apex moderately curved, hook-like. Aedeagal shaft (Fig. 3D, E) with dorsoapical projection hook-shaped in lateral view, ending curved and acute; with pair of basal dorsolateral processes, spine-like and short, not extending beyond gonopore. Paraphyses (Fig. 3D–E) paired, each robust and trifurcate with rami of unequal sizes and thickness.
Total length. 16.1 mm (holotype), 15.8 mm (other specimen).
External morphology. Forefemur with single intercalary row at apical half, anteroventral tuft restricted to apical fourth, and AM1 present, but not distinctly thicker than other setae. Metatibiae with six anterodorsal cuculate setae, row without intercalaries; anterodorsal setae similar in size and number to posterodorsal setae (seven setae); anteroventral and posteroventral row of cuculate setae unmodified. Characters of external morphology as in generic description by Young (1968: 57–59).
Coloration (holotype). Body (Fig. 2A–B) dark brown to reddish-brown, with yellow spots or maculae of various sizes on crown, clypeus, prothorax, mesothorax, forewings, and femora of all legs. Scutellum (Fig. 2A–B) with a faint median longitudinal yellow line interrupted by scutellar suture; portion posterior to scutellar suture lighter brown. Legs (Fig. 2A–B) reddish-brown to dark brown, with femora as described above.
Color variation found in the other specimen. Body (Fig. 2C–D) dark brown, spots or maculae of the head, prothorax, mesothorax, and legs, red. Scutellum (Fig. 2C–D) median longitudinal line also red, extending along entire length. Forewings (Fig. 2C–D) with yellow maculae. Legs (Fig. 2C–D) almost completely red, with some dark-brown areas.
Male genitalia. Pygofer (Fig. 3A) moderately produced posteriorly; posterior margin in lateral view produced into a rounded lobe slightly projected upwards; microsetae distributed from middle area to ventral and posteroventral margins. Valve (Fig. 3B) fused to subgenital plates posteriorly. Subgenital plates (Figs. 3A–B), in lateral view, with a slightly sinuous shape, projecting gradually upwards to apex which projects posteriorly, extending about as far as pygofer apex; in ventral view, each sub-triangular and fused to the other throughout almost their entire length, apex rounded; ventral and external lateral surfaces with numerous dispersed microsetae. Connective (Fig. 3C), in dorsal view, Y-shaped; stem widening apically; arms short and convergent apically. Style (Fig. 3C) extending posteriorly beyond apex of connective by approximately one-third of its length; apex slightly curved inwards, hook-like. Aedeagus (Fig. 3D–E) symmetrical; preatrium short; dorsal apodeme short and robust; shaft with pair of basal dorsolateral processes, each spine-like and short, not extending beyond gonopore, apical half with dorsolateral margins forming paired flanges that do not extend to apex, in lateral view, with dorsoapical hook-shaped projection, apex of projection slightly elongated posteroventrally ending curved and acute. Paraphyses (Fig. 3D–E) paired, basally separated, and connected to base of aedeagus by membrane; each paraphysis long, robust, and trifurcate, rami of unequal sizes and thickness: longer and thicker ramus (innermost in ventral view) extending slightly beyond apex of shaft and median ramus shortest and thinnest. Dorsal connective (Fig. 3F) U-shaped with short ventrolateral processes. Anal tube segment X elongate, in lateral view, almost twice longer than high; ventral margin longer than dorsal margin, with concavities on both margins with a median concavity in dorsal margin and with a posterior sub median concavity in ventral margin; without processes.
Female. Unknown.
Etymology. This species is named in honor of Dr. Andrés Felipe García Rincón, a passionate arachnologist who contributed greatly to the knowledge of the diversity of neotropical Opiliones. He was an advocate of science and the work of taxonomists and a dear friend, who passed away during the writing of this paper. We recognize his enormous passion and his ability to inspire people to work in science, and we hope that his name and memory will live on to posterity.
Notes. The new species is similar to Y. cartwrighti, mainly due to the color pattern of the dorsum, brown with yellow spots. However, it differs from the latter by: (1) comparatively less yellows spots and maculae on forewing; and notable differences in the structure of the male genitalia, highlighting: (2) apex of the style hook-like (Fig. 3C, straight in Y. cartwrighti); (3) aedeagal shaft with paired basal dorsolateral processes (preapical and lateral in Y. cartwrighti), not extending beyond gonopore and dorsoapical process more elongated, thicker, and curved at apex (Figs. 3E); and (4) each paraphysis trifurcate, rami of unequal sizes and thickness (Fig. 3C, similar to those of Y. coriacea). Besides the holotype, another specimen was studied lacking the abdomen, reason why it was not treated under the type series.
