Figures 8–19, 45–46
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); the retromarginal bicuspid teeth with the base elongated and slightly curved (Fig. 10); and the chelicerae with the mesal margin concave, while straight in P. areito sp. nov. (Fig. 3) and P. surcaribensis sp. nov. (Fig. 22). Female P. espositoae sp. nov. (Fig. 22) 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), P. surcaribensis sp. nov. (Fig. 26), P. wesolowskae sp. nov. (Fig. 33) and P. formosa comb. nov. (Fig. 51); and by having the SS as long as wide, while it is longer than wide in P. magna comb. nov. (Fig. 53).
Description. Male (Holotype, ICN-Ar-12796). Coloration (Fig. 45, 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, 17–18: 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, 18); 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, 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): 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.
