Etymology. The species epithet is a noun in apposition referring to the southern coast of Cuba where the species was found.
Diagnosis. Male Peckhamia surcaribensis sp. nov. can be distinguished from congeners by the embolus with the pdR elongate and thin, the rR reduced and wide and the pbR absent (Fig. 24). Additionally, male P. surcaribensis sp. nov. can be distinguished by the chelicerae lacking a concave mesal margin, which is the case in P. espositoae sp. nov. (Fig. 10) and P. wesolowskae sp. nov. (Fig. 29), and by the retromarginal teeth without a long base or slightly curved, while they have a long base in P. wesolowskae sp. nov. (Fig. 29) and are slightly curved in P. espositoae sp. nov. (Fig. 10). Female P. surcaribensis sp. nov. (Fig. 21) can be distinguished by having a developed dorsal abdominal white area, which is absent in P. wesolowskae sp. nov. (Fig. 28), reduced in P. espositoae sp. nov. (Figs 9) and P. magna comb. nov. (Fig. 52), and elongated in P. formosa comb. nov.; the SS as wide as PS, while narrower and not overlapping the PS in P. wesolowskae sp. nov. (Fig. 33), while SS and PS are overlapping in P. formosa comb. nov. (Fig. 51) and are longer than wide; and SS as long as wide in P. espositoae sp. nov. (Fig. 14) and P. formosa comb. nov. (Fig. 51). Finally, females P. surcaribensis sp. nov. can be distinguished from P. magna comb. nov. by having the CD as wide as PS, while the CD are thinner than PS in P. magna comb. nov. (Fig. 53).
Description. Male (Holotype, ICN-Ar-12798). Coloration (Fig. 47, in alcohol): Carapace reddish, black in interocular region and black between anterior and lateral eyes. Chelicerae, endites and labium gray to reddish. Legs gray to pale yellow. Abdomen ventrally gray to pale yellow; dorsally, yellow to pale reddish with two white areas on abdominal constriction. Total length 3.0. Carapace 1.3 long, 0.75 wide at position of PLE, 0.5 high, 0.67 times wider than high, flat from AME to PLE, then with a soft descent to inconspicuous groove just behind PLE; carapace 0.58 times longer than OQ. AER 0.7 wide, PER 0.8 wide. OQ 0.75 long, slightly longer than wide. Clypeus 0.1 high and lacking decoration. Sternum longer than wide, 0.55 long, 0.35 wide. Abdomen 1.7 long, longer than wide. Legs 4321; leg I: femur 0.6 long, 0.35 wide; patella 0.35 long, 0.15 wide, slightly thin, with patella somewhat flattened dorsally; femur slightly narrow dorsally. Palpal structure as in Figs 23–25: femur straight, 0.4 times longer than wide, femur 0.7 times longer than patella+tibia; RTA dark, wide (Fig. 25); embolus: pdR elongate and thin, close to rR, rR reduced and wide, pbR absent.
Female (Paratype: ICN-Ar-12799). Coloration as in male (Fig. 48, in alcohol). Total length 3.4. Carapace 1.45 long, 0.7 wide, 0.5 high; 0.48 times longer than OQ. AER 0.6 wide, PER 0.7 wide. OQ length 0.7. Clypeus 0.1 high and lacking decoration. Sternum 0.6 long, 0.4 wide. Abdomen 1.8 long, longer than wide. Leg formula 4213; leg I: femur 0.55 long, 0.27 wide; patella 0.35 long, 0.15 wide. Genitalia (Fig. 26): WE occupying much more than 1/2 of epigynal plate; CD curved; SS developed, almost as long as PS; PS as wide as CD; FD distant from CD; BG depressed or superficial.
