Figures 8–19 View FIGURE 8–14 View FIGURE 15–19 , 45–46 View FIGURES 43–48

Etymology. The species epithet is a noun in apposition in honor of Assistant Curator, Schlinger Chair of Arachnology Lauren Esposito, PhD (California Academy of Sciences, California, USA).

Diagnosis. Male Peckhamia espositoae   sp. nov. can be distinguished from congeners by the embolus with the rR developed and wider than pdR, and the pbR reduced or absent ( Fig. 12 View FIGURE 8–14 ); the retromarginal bicuspid teeth with the base elongated and slightly curved ( Fig. 10 View FIGURE 8–14 ); and the chelicerae with the mesal margin concave, while straight in P. areito   sp. nov. ( Fig. 3 View FIGURE 1–7 ) and P. surcaribensis   sp. nov. ( Fig. 22 View FIGURE 20–26 ). Female P. espositoae   sp. nov. ( Fig. 22 View FIGURE 20–26 ) can be distinguished by having the CD with an ovoid coil wider than PS, which is narrower than PS in P. areito   sp. nov. ( Fig. 7 View FIGURE 1–7 ), P. surcaribensis   sp. nov. ( Fig. 26 View FIGURE 20–26 ), P. wesolowskae   sp. nov. ( Fig. 33 View FIGURE 27–33 ) and P. formosa   comb. nov. ( Fig. 51 View FIGURE 49–55 ); and by having the SS as long as wide, while it is longer than wide in P. magna   comb. nov. ( Fig. 53 View FIGURE 49–55 ).

Description. Male (Holotype, ICN-Ar-12796). Coloration ( Fig. 45 View FIGURES 43–48 , in alcohol): Carapace yellow to black, black in interocular region and black between anterior and lateral eyes. Chelicerae, endites and labium reddish. Legs gray to reddish. Abdomen ventrally yellow to pale green; dorsally gray to pale green and black, with a white area over abdominal constriction. Total length 3.95. Carapace 1.9 long, 0.95 wide at position of PLE, 0.7 high, 0.73 times wider than high, flat from AME to PLE, then with a soft descent to inconspicuous groove just behind PLE; carapace 0.47 times longer than OQ. AER 0.85 wide, PER 0.95 wide. OQ length 0.90, slightly longer than wide. Clypeus 0.1 high and lacking decoration. Sternum longer than wide, 0.8 long, 0.25 wide. Abdomen 2.1 long, longer than wide. Leg formula 4132; leg I: femur 0.95 long, 0.55 wide; patella 0.53 long, 0.25 wide, enlarged, with patella somewhat flattened dorsally; femur wide dorsally. Palpal structure as in Figs 11–13 View FIGURE 8–14 , 17–18 View FIGURE 15–19 : femur straight, 0.23 times wider than wide, femur 0.37 times longer than patella+tibia; RTA dark, wide, ending in a prominent tip ( Figs 13 View FIGURE 8–14 , 18 View FIGURE 15–19 ); embolus: pdR as long as rR, rR two times wider than pdR, pbR absent.

Female (Paratype, ICN-Ar-12797). Coloration as in male ( Fig. 46 View FIGURES 43–48 , in alcohol). Total length 3.85. Carapace 1.85 long, 0.65 wide, 0.5 high; 0.4 times longer than OQ. AER 0.75 wide, PER 8.0 wide. OQ length 0.75. Clypeus 0.1 high and lacking decoration. Sternum 0.6 long, 0.35 wide. Abdomen 1.75 long, longer than wide. Leg formula legs 4321; leg I: femur 0.6 long, 0.3 wide; patella 0.35 long, 0.15 wide. Genitalia ( Fig. 14 View FIGURE 8–14 ): WE occupying much more than 1/2 of epigynal plate; CD with an ovoid coil, wider than PS; SS developed, as long as wide; PS as wide as CD; FD distant from CD; BG depressed or superficial.
