Figures 52–53

Descanso magnus Bryant, 1943: 479 pl. 4, fig. 36 (Holotype ♀: DOMINICAN REPUBLIC: Cordillera Central : Jarabacoa, leg. Philip J. Darlington, Jr., 2.VII.1938, IZ-MCZ 21965 —examined).

Diagnosis. Female Peckhamia magna comb. nov. ( Fig. 52 ) can be distinguished from other Peckhamia by having scattered white scales and the abdomen with a white stripe laterally.Additionally, female P. magna comb. nov. ( Fig. 53 ) can be distinguished by the CD with an ovoid coil (CD without an ovoid coil in P. areito sp. nov. ( Fig. 7 ), P. surcaribensis sp. nov. ( Fig. 26 ) and P. wesolowskae sp. nov. ( Fig. 33 )), and by the SS thinner than the CD (SS as wide as CD in P. espositoae sp. nov. ( Fig. 14 )).

Description. Female (Holotype, IZ-MCZ 21965). Coloration ( Fig. 52 , in alcohol): Carapace dark brown, black in interocular region and black between anterior and lateral eyes, with scattered white scales. Chelicerae, endites, labium and sternum dark brown. Leg I dark brown to gray, leg II–IV brown to gray. Abdomen ventrally dark brown; dorsally dark brown, with white area over abdominal constriction, and posterior two thirds with white stripe laterally. Total length 4.83. Carapace 2.04 long, 1.29 wide, 0.78 high; 0.54 times longer than OQ. AER 1.08 wide, PER 1.32 wide. OQ length 1.11. Clypeus 0.12 high and lacking decoration. Sternum 0.72 long, 0.42 wide. Abdomen 2.64 long, longer than wide. Leg formula 4132; leg I: femur 0.96 long; patella 0.54 wide. Genitalia ( Fig. 53 ): WE occupying much more than 1/2 of epigynal plate; CD ovoid coil; SS longer than wide; PS thinner than CD; FD distant from CD, and close to SS; BG depressed or superficial.

Other material examined. DOMINICAN REPUBLIC: Santiago Rodriguez: Mata Grande, National Park Armando Bermudez , 19.1896893°N, 71.0012313°W, leg. A. Deler-Hernández, 26.VIII.2014 (beating in rainforest), 1♀ (ICN-Ar-12874) .

Distribution. Only known from Cordillera Central and Santiago Rodriguez ( Fig. 56 ).
