Bioacoustics of Nops quito

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 ); membranes separating metatarsi and tarsi I–II with translucent fan-shaped ventral extension ( Fig. 15 ); tarsi I–II with three claws, paired claws with seven teeth; unpaired claw reflexed and without teeth ( Fig. 19 ), tarsi III–IV with three claws, paired claws with six teeth, unpaired claw small, not reflexed and without teeth ( Fig. 20 ); tarsi I–II with short translucent pulvillar lobe ( Fig. 19 ); tarsi III–IV without pulvillar lobe ( Fig. 20 ). GENITALIA: Palpal femur prolaterally with stridulatory pick basally ( Fig. 6 ). Palpal tibia prolaterally with brush of six setae ( Fig. 6 ). Cymbium pointed prolateral surface densely covered with strong setae; apicodorsal surface with patch of shortened setae ( Fig. 6 ). Bulb large, rounded ( Figs 6, 7 ). Embolus short, tip with transparent, pointed membrane ( Figs 6, 7 ). 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 ); 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 ). 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.
