MODISIMUS JIMA HUBER & FISCHER View in CoL SP. NOV.
( Figs 19 View Figures 17–37 , 39 View Figures 38–62 , 64 View Figures 63–82 , 127, 128 View Figures 124–129 , 195 View Figure 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 About ZFMK a) GoogleMaps .
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 View Figures 124–129 ; similar to M. femoratus and M. angulatus sp. nov.), and distinctive epigynum ( Fig. 39 View Figures 38–62 ; similar to M. femoratus and M. angulatus sp. nov.). Further distinguished from M. femoratus by shorter abdomen ( Fig. 19 View Figures 17–37 ), distinctive ventral notch on procursus ( Fig. 127 View Figures 124–129 ), bulb with more prominent dorsal apophysis ( Fig. 127 View Figures 124–129 ), 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 View Figures 17–37 : 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 View Figures 124–129 , very similar to M. femoratus , but frontal apophyses slightly more prominent in lateral view. Palps as in Figure 127 View Figures 124–129 , 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 View Figures 38–62 ); dorsal view very similar to M. femoratus ( Fig. 64 View Figures 63–82 ).
Distribution: Known from several localities in northcentral Dominican Republic ( Fig. 195 View Figure 195 ).
