(Figs. 3-4)
Etymology. From the Latin “ discolor ” (=variegated), which refers to the varied coloration of the tegument of the species.
Type material. Holotype (ICN-AO-1733), adult male preserved in 70% ethanol, penis in a microvial; paratype (ICN-AO-1734), adult female: Colombia, Magdalena Department, municipality of Ciénaga, San Pedro de la Sierra, Hacienda Hierba Buena (10° 53’ 42.49”N 73° 59’ 58.59”W; 2104 m elevation), 8 May 2016, Carlos Chinchilla P. leg. Paratypes: 1 ♂ and 1 ♀ (ICN-AO-1727) from same locality as the holotype, March 2017, Leonel Martínez leg.
Diagnosis. Ocularium and lateral margins of dorsal scutum with yellow tubercles. Posterior region of prosoma with a large white patch. Penis with one pair of MS-D similar in size to MS-A.
Comparisons. Most similar to Q. bella, Q. bimaculata, Q. hermesi sp. nov., and Q. marginata, due to the lack of enlarged tubercles on the posterior lateral margins of dorsal scutum, but can be distinguished from them by the combination of the following characters: presence of a white patch on the posterior half of the prosoma, absence of colored tubercles on abdominal areas and free tergites.
Description. Male holotype (ICN-AO-1733).
Measurements. CL: 2.0; DSW: 3.3; CW: 2.8; DSL: 4.1; Fe: 3.2, 7.9, 5.9, 8.5; Pa: 0.7, 1.5, 1.2, 1.4; Ti: 2.2, 5.4, 2.7, 4.7; Mt: 4.1, 7.9, 5.3, 9.0.
Color in ethanol. Background of the dorsal scutum Raw Umber (III 17 m), prosoma with Old Gold (XVI 19’ i) patches in a reticulated pattern. Abdominal scutum with Old Gold (XVI 19’ i) patches surrounding areas I-IV, and Brussels Brown (III 15 m) patches between abdominal areas and lateral margins, posteriorly with patches Barium Yellow (XVI 23’ d). Ocularium and lateral margins of the dorsal scutum tubercles Barium Yellow (XVI 23’ d). Legs Light Brownish Olive (XXX 19’’ k), chelicerae Naples Yellow (XVI 19’ d), basal segment of the chelicerae with a reticulated pattern Old Gold (XVI 19’ i) and pedipalps Pale Veronese Green (XVIII 31’ f), with some patches Orange Citrine (IV 19 k).
Dorsum (Fig. 3A). Dorsal scutum β type, anterior margin with three tubercles each side. Ocularium with threefour tubercles near to the eyes, two-three of them colored pale yellow. Prosoma with eight tubercles, on a white patch anterior to groove I. Lateral margins with one row of 18 yellow tubercles, which are elevated posteriorly (Fig. 3B). Area I divided, with three tubercles each side. Area II with one row of four tubercles. Area III with one pair of sharp and divergent spines. Area IV with one tubercle each side. Free tergites with one row of five (I) or four (II-III) tubercles, in the latter tergites one pair is larger. Anal plate with small, scattered tubercles.
Venter. Cx I-III with one row of setiferous tubercles increasing in size distally, IV with sparse, small tubercles. Chelicerae. Segment I with a few small, setiferous tubercles on the bulla; fixed and movable fingers with three teeth each (Fig. 3E).
Pedipalps (Fig. 3 C-D). Tr with four dorsal and two ventral setiferous tubercles. Fe with four dorsal and one row of ventral tubercles, with one subdistal prolateral tubercle. Ti: mesal IiiIi, ectal IiIi; Ta: mesal IiIi, ectal IiIi.
Legs. At least three times longer than body length; Cx IV with one dorsoapical tubercle and a few scattered small tubercles. Tr I-IV with a few scattered granules. Fe III and IV with ectal and mesal apical tubercles. Tarsal process present. TF: 6(3)/14(3)/7/7.
Penis (Fig. 4 A-D). Lateral margins of VP slightly constrained basally and subdistally; distal margin concave, with corners projected. Three pairs of spatulate and apically curved MS-C. One pair of MS-A almost as long as MS- C. One pair of cilindrical MS-D curved dorsally. Two pairs of MS-E on the ventral surface of VP. Microsetae type 4 distributed on the midfield of VP, which is expanded proximally up to the corner field, but without joining in the middle of VP. Glans wide and conical, stylus short, slightly wide at apex, with submedian ventral process.
Female paratype (ICN-AO-1734).
Measurements CL: 2.0; DSW: 3.5; CW: 2.6; DSL: 4.2; Fe: 3.0, 7.5, 5.4, 7.6; Pa: 0.8, 1.4, 1.2, 1.3; Ti: 2.1, 5.1, 3.1, 4.3; Mt: 3.7, 7.2, 4.6, 7.5.
Very similar to the male, but with tubercles on free tergites II and III sharper and larger.
Distribution. Recorded only at the type locality in the Sierra Nevada of Santa Marta (Magdalena Department), in a fragment of moist forest (Fig. 5).
