Moreno-Gonzálezleg. (ICN-Ar 10855).   Etymology.The specific epithet honors the Yariguí people, an extinct indigenous group that inhabited the region and the particular location where the species was found, the Serranía de los Yariquíes National Natural Park. It has been said that they committed mass suicide instead of submitting to Spanish colonial rules; noun in apposition.   Diagnosis.Males of  A. yarigui  sp. nov.resemble those of  A. suniin having a vRTA and an untwisted embolus. They are distinguished from the latter by the vRTA laminar, wide and distally indented ( Figs 23–26; slender, prong-like in  A. suni, Figs 6–7) and by the embolus with a short tip ( Figs 21–22, 25, 27; long and slender in  A. suni, Fig. 12).   Description.

Median lobe of trilobate membrane acuminate and longer than lateral projections ( Fig. 28). Chelicerae with four anterior and five posterior teeth, and approximately 17 intermarginal denticles between them ( Figs 29–30). Male palp: tibia long, slightly longer than cymbium; dRTA slender and conical; vRTA as in diagnosis; tegulum with U-shaped spermophor; embolus short with wide base, arising from tegulum at approximately 11:30 o´clock position; conductor hyaline, laminar, arising from tegulum at 12 o´clock position ( Figs 21–27). Coloration: General coloration pale brown. Dorsal shield of prosoma laterally with some brown narrow marks, six central small patches next to fovea and one longitudinal mark behind fovea. Legs with numerous brown spots distributed randomly and one irregular mark per spine base encircling it. Sternum, endites and labium pale brown. Opisthosoma light brown with four dorsal and anterior spots, and numerous bright guanine crystal spots under tegument ( Figs 18–20).  Female:Unknown.   Distribution.Known only from the typelocality, at the Serranía de los Yariquíes National Natural Park, in the Andean department of Santander, Colombia( Fig. 1).  Natural history. The male holotypewas collected by beating low vegetation in a highly conserved wet Andean forest. Subadult males and juveniles were collected in the same type locality by beating low vegetation, and manually during the day, in both secondary and very-intervened ecosystems.   Comments.  Anaptomecus yarigui  sp. nov.is known solely from one male and there is another species from Colombia,  A. levyi, known solely from a female. Nevertheless, we consider them separate species due to the fact that the typelocalities have distinctly different altitudes, and they are more than 300 kmapart from each other. Both in a region, as northern Andes, known for its extremely high levels of diversity and endemisms in plants and animals ( Halffter 1992), including spiders ( Galvis 2017).  Anaptomecus levyiwas collected between 800–1200 m, probably in the Susumuco Mountain rangein the department of Meta, just east of Bogotá[see Jäger et al. (2009)for discussion on the typelocality], with altitudes reaching  1900 m, while  A. yarigui  sp. nov.was collected between 1700–2200 m, in the Serraníade los Yariguíes, in the department of Santander, with much higher altitudes, more than  3200 m.   FIGURES 2–17. 2–9.Schematic drawings of the male palpal tibia of  Anaptomecusspp. 2–3  A. longiventrisSimon, 1903(2 ventral, 3 retrolateral); 4–5  A. paruGuala, Labarque & Rheims, 2012(4 ventral, 5 retrolateral); 6–7  A. suniGuala, Labarque & Rheims, 2012(6 ventral, 7 retrolateral); 8–9  A. temiiJäger, Rheims & Labarque, 2009(8 ventral, 9 retrolateral). 10–13.Schematic detail of embolus and conductor of  Anaptomecusspp. 10  A. longiventrisSimon, 1903; 11  A. paruGuala, Labarque & Rheims, 2012; 12  A. suniGuala, Labarque & Rheims, 2012; 13  A. temiiJäger, Rheims & Labarque, 2009. 14–17.Schematic drawings of female Epigyne of  Anaptomecusspp, ventral views. 14  A. longiventrisSimon, 1903; 15  A. levyiJäger, Rheims & Labarque, 2009; 16  A. paruGuala, Labarque & Rheims, 2012; 17  A. suniGuala, Labarque & Rheims, 2012.

(2009); 20–23, 27–28, 32–33 modified from Guala et al.(2012). In addition, both species show differences in coloration pattern, leg measurements and cheliceral dentition. While  A. yariguiis generally pale brown, with a darker pattern on the dorsal shield of prossoma and opisthosoma completely covered by guanine crystal spots,  A levyiis generally pale yellow with simple pale brown marginal bands on prossoma and fewer guanine spots on opisthosoma. Moreover,  Anaptomecus yariguihas 6–7 retromarginal teeth on the chelicerae and leg formula 2143, while  A. levyihas 5 retromarginal teeth and leg formula 1243. 2028520955 [323,436,764,787] 2015-09-23 2015-09-25 2015-09-23 Finca El Prado & J.
