Nops cesari new species

Figs 1–5 , 14 , 17, 18 .

Type material. Male holotype from Ecuador, Cotopaxi Province, Casa Cesar Tapia, 13 September 2013, sifting litter, E. Tapia, N. Dupérré (deposited at QCAZ). Female paratype, same data. EXAMINED.

Etymology. In honor of Don César Tapia for his help in collecting spiders and his tremendous work in Otonga Reserva Integral in protecting the environment.

Diagnosis. Males and females can be distinguished from all other members of Nops by their short transluscent keel ( Fig. 14 ), longer in other species. Additionally, males can be distinguished by their long embolus with a short, triangular transparent membrane at apex ( Fig. 3 ). From species with similar embolus N. largus and N. simla by their much smaller, oval bulb ( Figs 2, 3 ).

Description. Male: Total length: 3.2; carapace length: 1.5; carapace width: 1.1.

CEPHALOTHORAX: Carapace elongated pear-shaped widest between coxae II–III; bright orange, reticulate; pars cephalica flat; covered by scattered setae; thoracic groove absent ( Fig. 1 ). Clypeus, ~ 2x as high as AME. Sternum longer than wide, bright orange, reticulate; covered by 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, dorsally light gray with 4–5 light chevrons ( Fig. 1 ); ventrally light yellow. LEGS: Bright orange; without spines; leg formula 4123; total length leg I: 0.45; II:0.4: III:0.4: IV: 0.5; metatarsi I–IV entire; tarsi I–IV divided into two subsegments; apical part of metatarsi I–II with short translucent ventral keel ( Fig. 14 ); membranes separating metatarsi and tarsi I–II with translucent fan-shaped ventral extension ( Fig. 14 ); tarsi I–II with three claws, paired claws with nine teeth, unpaired claw elongated, reflexed and without teeth ( Fig. 17 ); tarsi III–IV with three claws, paired claws with four teeth, unpaired claw elongate, reflexed and without teeth ( Fig. 18 ); tarsi I–IV with translucent pulvillar lobe ( Figs 17, 18 ). GENITALIA: Palpal femur prolaterally with stridulatory pick basally ( Fig. 2 ). Palpal tibia prolaterally with brush of seven setae ( Fig. 2 ). Cymbium pointed, prolateral surface densely covered with strong setae; apicodorsal surface with patch of shortened setae ( Fig. 2 ). Bulb small, oval ( Figs 2, 3 ). Embolus long, tip with transparent triangular membrane ( Fig. 3 ).

Female: Total length: 2.3; carapace length: 1.1; carapace width: 0.59. CEPHALOTHORAX: Light orange, reticulate. Clypeus, labium, endites as in male. Chelicerae yellowish. ABDOMEN: Dorsally dark gray with 4–5 chevrons; ventrally light yellow. LEGS: Same as male; total length leg I: 0.44; II:0.39: III:0.38: IV: 0.49; palp yellow; palpal femur prolaterally with stridulatory pick basally; palpal tibia prolaterally with brush of nine 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. 5 ).
