( Figs 23, 24 View Figures 17–37 , 46 View Figures 38–62 , 69 View Figures 63–82 , 145–147 View Figures 142–147 , 198)

Type: Male holotype from near Seguin (18°18.2 ′ N, 72°17.5 ′ W, ~ 990 m a.s.l.), Dept Sud-Est, Haiti GoogleMaps ; degraded forest with plantations; in the deeper, wet areas of piles of banana sheaths on the ground, 28 November 2007 (B.A. Huber), in ZFMK ( Haiti 6a) .

Etymology: The species name is derived from the Creole words epè (thick) and pye (leg), and refers to the thick femora of this species; it is used as a noun in apposition.

Diagnosis: Medium-sized species with low ocular area ( Fig. 24 View Figures 17–37 ; similar to M. fuscus ), enlarged femora (similar to M. fuscus ), contiguous pore plates ( Fig. 147 View Figures 142–147 ; similar to M. fuscus ); distinguished from M. fuscus by monochromous legs, shape of epigynum ( Fig. 46 View Figures 38–62 ; no scape), and unmodified male chelicerae ( Fig. 146 View Figures 142–147 ).

Male (holotype): Total length, 2.8; carapace width, 1.27; Leg 1: 12.3 (3.4 + 0.5 + 3.5 + 3.8 + 1.1); tibia 2, 2.4; tibia 3, 1.9; tibia 4, 2.9. Tibia 1 L/d: 22. Habitus as in Figures 23 and 24 View Figures 17–37 ; carapace, ocular area, and clypeus mostly brown, only lateral side of ocular area light ochre, sternum monochromous brown; legs monochromous, same colour as carapace, slightly lighter distally; abdomen bluish grey with many black spots, except heart area and ventrally; genital area and plate in front of spinnerets brown. Ocular area only slightly elevated; thoracic furrow distinct. PME– PME, 115 Mm; PME 95 Mm diameter; PME–ALE, 60 Mm; AME–AME, 20 Mm; AME diameter, 25 Mm. Sternum wider than long (0.85/0.55), unmodified. Chelicerae unmodified ( Fig. 146 View Figures 142–147 ). Palps as in Figure 145 View Figures 142–147 , coxa with light retrolateral apophysis, femur with basal and distal ventral apophyses, procursus rather simple, with membranous structures dorsodistally, bulb with flattened distal apophysis, with small subdistal hump on prolateral side. Legs without spines; retrolateral trichobothrium on tibia 1 at 25%; all femora with many short vertical hairs; curved hairs on all tibiae and metatarsi; prolateral trichobothrium missing on tibia 1, present on all other tibiae; tarsus 1 with ~15 pseudosegments, fairly distinct, except proximally.

Variation: The second male is generally lighter, and the light marks lateral to the ocular area extend further back; tibia 1, 3.4.

Female: In general, similar to male, with curved hairs also on femora, and light areas on carapace, as in lighter male. Tibia 1: 3.2. Epigynum, simple flat plate ( Fig. 46 View Figures 38–62 ); dorsal view as in Figures 69 View Figures 63–82 and 147 View Figures 142–147 .

Distribution: Known from type locality only ( Fig. 198).

Material examined: Haiti: Dept Sud-Est, near Seguin, 1♂, holotype above; same data, 1♂ and 1♀ ( ZFMK, Haiti 6); same data, 2♂, in pure ethanol ( ZFMK, Haiti 80) .
