Figures 1–7 , 43–44

Etymology. The species epithet is a noun in apposition referring to the ceremonies of the Taíno, the principal ethnic group of Hispaniola prior to the arrival of the colonizers.

Diagnosis. Male Peckhamia areito sp. nov. can be distinguished from other species by the embolus with the pdR longer than the rR ( Fig. 5 ); and the mesal margin of the male chelicerae which is straight: concave in P. espositoae sp. nov. ( Fig. 10 ) and P. wesolowskae sp. nov. ( Fig. 29 ). Female P. areito sp. nov. can be distinguished by having the SS longer than wide ( Fig. 7 ), while the SS is as long as wide in P. espositoae sp. nov. ( Figs 14 ) and P. formosa comb. nov. ( Figs 51 ); the PS with an ectal distal loop, while lacking an ectal distal loop in P. surcaribensis sp. nov. ( Fig. 26 ) and P. wesolowskae sp. nov. ( Fig. 33 ); and by having PS as wide as CD, while PS is thinner than CD in P. magna comb. nov. ( Fig. 53 ).

Description. Male (Holotype, ICN-Ar-12794). Coloration ( Fig. 43 , in alcohol): Carapace reddish to black, OQ black and interocular region black. Chelicerae, endites and labium reddish to dark; sternum black. Leg I reddish to black; coxa reddish; femur reddish to black; patella to tarsus, light reddish. Legs II to III gray to black; coxa and tibia to tarsus gray. Leg IV gray to black; coxa black; femur black to pale yellow; patella to tarsus light yellow to gray. Abdomen ventrally black; dorsally reddish to black with a white area over abdominal constriction. Total length 3.6. Carapace 1.6 long, 0.9 wide at level of PLE, 0.65 high, 0.7 times wider than high, flat from AME to PLE, with a soft descent to an inconspicuous groove just behind PLE; carapace 0.7 times longer than OQ. AER 0.8 wide, PER 0.95 wide. OQ, 1.0 long, slightly longer than wide. Clypeus 0.1 high and lacking decoration. Sternum longer than wide, 0.75 long, 0.4 wide. Abdomen 1.7 long, with very slight constriction at end of first third. Leg formula 4231; leg I: femur 0.83 long, 0.4 wide; patella 0.5 long, 0.2 wide, enlarged, with patella somewhat flattened dorsally; femur, wide dorsally. Palpal structure as in Figs 4–6 : femur straight, 0.31 times longer than wide, femur 0.63 times longer than patella+tibia; RTA dark, wide, with a prominent tip ( Fig. 6 ); embolus pdR close to rR; rR reduced in size; pbR wider than long.

Female (Paratype, ICN-Ar-12795). Coloration as in male ( Fig. 44 , in alcohol). Total length 4.1. Carapace 1.9 long, 1.15 wide, 0.75 high; 0.66 times longer than OQ. AER 0.95 wide, PER 1.15 wide. OQ length 0.7. Clypeus 0.1 high and lacking decoration. Sternum 0.75 long, 0.45 wide. Abdomen 2.25 long, longer than wide. Leg formula 4213; leg I: femur 1.15 long, 0.63 wide; patella 0.75 long, 0.35 wide. Genitalia ( Fig. 7 ): WE occupying much more than 1/2 of epigynal plate; CD curved; SS well developed, longer than wide; PS as wide as CD, with an ectal distal loop; FD distant from CD; BG depressed or superficial.
