( Figs 7, 8 View Figures 5–16 , 25 View Figures 17–37 , 58 View Figures 38–62 , 80 View Figures 63–82 , 179–181 View Figures 179–184 , 200 View Figure 200 )

Type: Male holotype from Le Prete (18°15.9 ′ N, 73°56.7 ′ W; ~ 170 m a.s.l.), Dept Sud , Haiti GoogleMaps , in small web under dead mango leaves on the ground, near river, 2 December 2007 (B.A. Huber), in ZFMK ( Haiti 16a) .

Etymology: The name refers to the fact that all specimens were collected under dry mango leaves on the ground; it is used as a noun in apposition.

Diagnosis: Small, long-legged species, with pair of small marks on carapace ( Fig. 25 View Figures 17–37 ), distinctive pattern of modified hairs on chelicerae ( Fig. 180 View Figures 179–184 ), and distinctive shapes of epigynum ( Fig. 58 View Figures 38–62 ) and procursus ( Fig. 179 View Figures 179–184 ).

Male (holotype): Total length, 1.1; carapace width, 0.63. Leg 1: 15.5 (3.9 + 0.3 + 4.0 + 6.0 + 1.3); tibia 2, 2.2; tibia 3, 1.5; tibia 4, 1.9. Tibia 1 L/d: 55. Habitus as in Figures 7, 8 View Figures 5–16 , 25 View Figures 17–37 , carapace pale ochre-yellow, with dark mark medially, and a pair of small marks laterally between legs 2 and 3, clypeus also darkened, sternum whitish with pair of darker lateral areas frontally; legs ochre-yellow, with indistinct darker rings on femora and tibiae subdistally, patellae also slightly darker; abdomen bluish grey, with large black and small white spots dorsally and laterally; genital area and plate in front of spinnerets also slightly darker. Ocular area elevated; thoracic furrow distinct. PME–PME, 60 Mm; PME diameter, 70 Mm; PME– ALE, 70 Mm; small median pigment spot in place of AME, no lenses. Sternum wider than long (0.45/0.35), unmodified. Chelicerae with ~15 modified hairs on each side, six of them on low elevation ( Fig. 180 View Figures 179–184 ). Palps as in Figure 179 View Figures 179–184 , coxa with light retrolateral apophysis, femur with large proximal flap and long distal ventral apophysis, procursus simple, tapering distally, with membranous structures distally, barely visible in dissecting microscope, and bulbal apophysis with transparent lateral flap. Legs without spines; retrolateral trichobothrium on tibia 1 at 16%; all femora with many short vertical hairs; curved hairs on tibiae and metatarsi 1 and 2; prolateral trichobothrium missing on tibia 1, present on all other tibiae; tarsus 1 with more than 15 pseudosegments, distally fairly distinct.

Variation: The second male has a lighter abdomen and fewer white spots. Tibia 1: 4.1.

Female: In general, similar to male, but dark rings on legs clearly more distinct. Tibia 1: 2.2 and 2.3. Epigynum, simple plate, with lateral sclerites converging posteriorly, and median transverse sclerite ( Fig. 58 View Figures 38–62 ); dorsal view as in Figures 80 View Figures 63–82 , 181 View Figures 179–184 .

Distribution: Known from type locality only ( Fig. 200 View Figure 200 ).

Material examined: Haiti: Dept Sud, Le Prete, 1♂, holotype above; same data, 1♂ and 2♀ ( ZFMK, Haiti

16); same data, 1♂ and 2♀, in pure ethanol ( ZFMK, Haiti 89) .
