description: MODISIMUS JIMA HUBER & FISCHER SP. NOV.   
(Figs 19, 39, 64, 127, 128, 195)  
 Type: Male holotype from near Jima (19°01.4 ′ N, 70°28.8 ′ W), Monseñor Nouel Prov., Dominican Republic; degraded forest at brook through plantation, ~ 700 m a.s.l., near ground, 8 November 2005 (B.A. Huber), in ZFMK (DR 12 a).   
 Etymology: The species name refers to the type locality; it is used as a noun in apposition.   
 Diagnosis: Medium-sized species with pair of small projections, with weakly modified hairs on male chelicerae (Fig. 128; similar to M. femoratus and M. angulatus sp. nov.), and distinctive epigynum (Fig. 39; similar to M. femoratus and M. angulatus sp. nov.). Further distinguished from M. femoratus by shorter abdomen (Fig. 19), distinctive ventral notch on procursus (Fig. 127), bulb with more prominent dorsal apophysis (Fig. 127), cheliceral frontal projections more prominent, and different pattern on male genital area (shorter lateral arms); distinguished from M. angulatus sp. nov. by pattern on sternum (lateral border not broken), evenly curved abdomen dorsally, and male cheliceral projections slightly closer together.   
 Male (holotype): Total body length, 2.2; carapace width, 1.1. Leg 1: 20.4 (5.2 + 0.4 + 5.2 + 7.9 + 1.7); tibia 2, 3.4; tibia 3, 2.8; tibia 4, 3.1. Tibia 1 L/d: 44. Habitus as in Figure 19: carapace pale ochre-yellow, ocular area posteriorly brown, clypeus with pair of brown bands, sternum laterally brown, and whitish medially; legs light brown, tips of femora and tibiae light; abdomen bluish grey, with black spots dorsally and laterally, genital area and area in front of spinnerets brown. Ocular area strongly elevated; thoracic furrow distinct. PME–PME, 95 Mm; PME diameter, 115 Mm; PME–ALE, 125 Mm; AME–AME, 25 Mm; AME diameter, 20 Mm. Sternum wider than long (0.65/ 0.45), unmodified. Chelicerae as in Figure 128, very similar to M. femoratus, but frontal apophyses slightly more prominent in lateral view. Palps as in Figure 127, very similar to M. femoratus, but procursus with more distinctive notch ventrally, and bulb with more prominent dorsal apophysis. Legs with short spines on femur 1 (two rows, of ~30 and 25 spines each) and femur 2 (two rows, of ~20 each), and many short vertical hairs on all femora; curved hairs on tibiae 1–3; retrolateral trichobothrium on tibia 1 at 9%; prolateral trichobothrium missing on tibia 1, present on other tibiae; tarsus 1 with ~25 pseudosegments.   
 Variation: Some males with subdistal darker rings on femora (indistinct also on tibiae). Tibia 1 in 13 males: 4.9–6.0 (mean 5.4).   
 Female: In general similar to male, with rings on legs often distinct; tibia 1 in six females: 3.4–4.0, mean 3.8. Epigynum, similar to M. femoratus, but posterior border different (Fig. 39); dorsal view very similar to M. femoratus (Fig. 64).   
 Distribution: Known from several localities in northcentral Dominican Republic (Fig. 195).
