Figs 6–9 View FIGURES 6 – 9 , 15 View FIGURES 14 – 16. 14 , 19, 20 View FIGURES 17 – 22 .

Type material. Male holotype from Ecuador, Pichincha Province, Quito, 2810m , 00°W 00°S, 10 Oct. 1998, S. Castelo (deposited at QCAZ). EXAMINED.

Etymology. The specific name is a noun in apposition taken from the type locality, Quito Ecuador.

Diagnosis. Males and females are distinguished from most species of Nops by the greenish color pattern of their abdomen ( Fig. 8 View FIGURES 6 – 9 ). From species with similar pattern: Nops variabilis Keyserling 1877 by the absence of a yellow middle longitudinal band and a triangular mark at apex ( Keyserling 1877: fig. 8); N. gertschi Chickering 1967 by the absence of two irregular light greenish dorsolateral band ( Chickering 1967: p. 9); and N. ursumus Chickering 1967 by the absence of five pairs of dark greeningish spots ( Chickering 1967: p. 16). Furthermore, males are distinguished from N. variabilis Keyserling 1877 and N. sublaevis Simon 1893 by their longer embolus, strongly bent ( Figs 6, 7 View FIGURES 6 – 9 ) whereas it is shorted and uniformly curved in the two later species.

Description. Male: Total length: 5.1; carapace length: 2.2; carapace width: 1.2.

CEPHALOTHORAX: Carapace elongated pear-shaped widest between coxae II–III; bright orange, reticulate; pars cephalica flat; covered by scattered setae; thoracic groove absent. Clypeus, ~ 2x as high as AME. Sternum longer than wide, bright orange, punctate; covered by needlelike setae. Labium and endites bright orange. Chelicerae bright orange; with median lamina with rounded tip; lateral surface with stridulatory ridges. EYES: 2, medium-sized, close together surrounded by oval ring of black pigment. ABDOMEN: Elongate oval, dorsally dark grayish with a tinge of blue with 4–5 light green chevrons; ventrally light green. LEGS: Bright orange; without spines; total length leg I: 0.64; II:0.60: III:0.5: IV: 0.8; metatarsi I–IV entire; tarsi I–IV divided into two subsegments; apical part of metatarsi I and II with long translucent ventral keel ( Fig. 15 View FIGURES 14 – 16. 14 ); membranes separating metatarsi and tarsi I–II with translucent fan-shaped ventral extension ( Fig. 15 View FIGURES 14 – 16. 14 ); tarsi I–II with three claws, paired claws with seven teeth; unpaired claw reflexed and without teeth ( Fig. 19 View FIGURES 17 – 22 ), tarsi III–IV with three claws, paired claws with six teeth, unpaired claw small, not reflexed and without teeth ( Fig. 20 View FIGURES 17 – 22 ); tarsi I–II with short translucent pulvillar lobe ( Fig. 19 View FIGURES 17 – 22 ); tarsi III–IV without pulvillar lobe ( Fig. 20 View FIGURES 17 – 22 ). GENITALIA: Palpal femur prolaterally with stridulatory pick basally ( Fig. 6 View FIGURES 6 – 9 ). Palpal tibia prolaterally with brush of six setae ( Fig. 6 View FIGURES 6 – 9 ). Cymbium pointed prolateral surface densely covered with strong setae; apicodorsal surface with patch of shortened setae ( Fig. 6 View FIGURES 6 – 9 ). Bulb large, rounded ( Figs 6, 7 View FIGURES 6 – 9 ). Embolus short, tip with transparent, pointed membrane ( Figs 6, 7 View FIGURES 6 – 9 ).

Female: Total length: 9.0; carapace length: 3.1; carapace width: 2.1. CEPHALOTHORAX: Carapace elongated pear-shaped widest between coxae II–III; bright orange, reticulate; pars cephalica flat; covered by scattered setae; thoracic groove absent. Sternum, labium, endites and chelicerae as in male. EYES: 2, separated by their width, surrounded by oval horizontal ring of black pigment. ABDOMEN: Elongate oval, dorsally dark grayish with a tinge of blue with 4–5 dark green chevrons ( Fig. 8 View FIGURES 6 – 9 ); ventrally light green. LEGS: Same as in male; total length leg I: 0.92; II:0.85: III:0.72: IV: 1.05; palp orange, palpal tibia prolaterally with brush of seven setae; palpal tarsus expanded, without claw, ventral surface densely covered with strong setae; apicodorsal surface with patch of shortened setae. GENITALIA: Epigastric region yellowish, well sclerotized ( Fig. 9 View FIGURES 6 – 9 ).

Note: In 1913, Berland reported the presence of Nops variabilis Keyserling 1877 in Ecuador, one female from Quito and one male from Alausi. He also included an illustration of the male palp, the palp drawn by Berland (1913: fig. 11) is very similar to the palp of Nops quito n. sp. I believe that the record and illustration presented by Berland as Nops variabilis Keyserling 1877 are in fact of Nops quito n. sp., and that he simply misidentifed them.

Keyserling description and illustration of the abdominal pattern of Nops variabilis is quite clear (translated from German): “Abdomen dorsal brown with a narrow yellow long band over the middle, from the rear part of each sides three short yellow strokes branch off this yellow middle band, in his rearmost part, a yellow triangle”. None of the specimens of Nops quito n. sp. present this pattern of coloration, in fact their abdominal pattern shows little variation. Some variation can be observed in the thickness of the chevrons depending on the size of the abdomen, as well as some discoloration due to preservation in alcohol.
