Diagnosis

Can be separated from all the other species of the genus in having the coda shorter than mid-bulge, maximum width of dorsal scutum equal to maximum length ( Fig. 11A View Fig ). Three basitarsomeres in legs I and III ( Fig. 11 View Fig B–C). VP of the penis with MS D1 equally distanced from MS D2 and MS C2 ( Fig. 12 View Fig A–D).

Etymology

Noun in apposition from Iguaque, which in the Chibcha language means ‘vigorous mountain’ and was the cultural epicenter in the Amerindian period; as sacred territory it represented, for the Muiscas, the universe in continuous regeneration: birth, fecundity, fertility and initiation, symbol of ascent and interior knowledge. Also, it is the name of the Sanctuary that is the type locality of the species.

Description

Male holotype (MNRJ 19765)

MEASUREMENTS. CL = 1.5, AL = 2.6, CW = 2.7, AW = 3.6, IOD = 0.6, Fe I = 2, Ti I = 1.3, Fe II = 3, Ti I = 2.1, Fe III = 2.8, Ti III = 1.6, Fe IV = 2.9, Ti IV = 2.5.

DORSUM ( Fig. 11 View Fig A–D). Dorsal scutum alpha-type, areas I–III, anterior and posterior margin of scutum, and lateral margins with granules. Free tergites with rows of granules and anal operculum finely granular. Posterior margin of dorsal scutum convex. Marginal lateral grooves of areas I and II with fragmented yellow rails.

VENTER. Free sternites finely granular; coxae II–IV finely and uniformly granular; coxa I with longitudinal row of tubercles and smooth area corresponding to lace area of pedipalp. Anal operculum finely granular.

CHELICERAE ( Fig. 12 View Fig F–G). Basichelicerite finely and uniformly granular covered without notable tubercles, ectodistal small setiferous protuberance; movable finger with row of eight sharp teeth; fixed finger with seven triangular teeth (the middle teeth are larger).

PEDIPALPS ( Fig. 12E View Fig ). Trochanter with strong ventral apophysis. Femur dorsally convex without pronounced dorsal keel or tubercles, with ventral row of three well-formed setiferous tubercles and a mesodistal process. Patella with mesal keel. Shallow slit along tibia mesal surface, separating dorsal and ventral sides.

LEGS ( Fig. 11 View Fig E–F). Coxa IV granulated with distal prodorsal small apophysis. Femur IV substraight, with two longitudinal ventral rows of small tubercles along entire length. Tarsal counts: 6(3)/8-7(3)/6/6.

COLOR ( Fig. 11 View Fig ). Body background Strong Yellowish Brown (74) mottled in Deep Yellowish Brown (75), ladder mask Pale Greenish Yellow (104). Appendages (except coxae) Brilliant Yellow (83).

Female

Similar to males, with coda longer. Basitarsomeres I, III and IV not enlarged. Tarsal counts (MNRJ 19379): 6(3)/7-6(3)/6/6.
