MODISIMUS MIRI HUBER & FISCHER View in CoL SP. NOV.

( Figs 61 View Figures 38–62 , 82 View Figures 63–82 , 190, 191 View Figures 190–194 , 201 View Figure 201 )

Type: Male holotype from Reserva Científica Loma Quita Espuela, near summit (19°21.5 ′ N, 70°09 ′ W), Duarte Prov., Dominican Republic; 900 m a.s.l., underside of manacla (palm) leaves, 10 November 2005 (B.A. Huber), in ZFMK ( DR 23 View Materials a) GoogleMaps .

Etymology: The species name honours the Dominican poet and writer Pedro Julio Mir Valentín (1913– 2000).

Diagnosis: Medium-sized, pale-greenish, long-legged species, with six eyes, distinguished from close relatives ( M. palvet sp. nov. and M. berac sp. nov.) by epigynum shape ( Fig. 61 View Figures 38–62 ) and pair of apophyses above fang joints ( Fig. 190 View Figures 190–194 ); further distinguished from M. palvet sp. nov. by pattern of club-shaped modified hairs on male chelicerae ( Fig. 190 View Figures 190–194 ) and slightly wider procursus.

Male (holotype): Total length, 1.9; carapace width, 0.80. Leg 1: 24.0 (5.8 + 0.3 + 5.8 + 9.8 + 2.3); tibia 2, 4.0; tibia 3, 2.8; tibia 4, 3.1. Tibia 1 L/d: 72. Habitus similar to M. palvet sp. nov. (cf. Fig. 35 View Figures 17–37 ), carapace pale ochre-yellow to whitish, clypeus with wide brown distal margin, sternum whitish; legs pale ochre-yellow, with darker patella area and tibia–metatarsus joints; abdomen pale greenish grey with purplish marks dorsally at heart area, monochromous ventrally. Ocular area slightly elevated; thoracic furrow distinct but shallow. PME–PME, 95 Mm; PME diameter, 70 Mm; PME–ALE, 80 Mm; no AME. Sternum slightly wider than long (0.60/0.55), unmodified. Chelicerae with about ten club-shaped modified hairs on each side, and distinctive apophyses above fang joints ( Fig. 190 View Figures 190–194 ). Palps very similar to M. palvet sp. nov. (cf. Fig. 185 View Figures 185–189 ), procursus slightly wider, and bulbal apophysis slightly wider and shorter. Long spines on femora 1 (three or four) and femora 2 (two), many short vertical hairs on all femora; without curved hairs; retrolateral trichobothrium on tibia 1 at 7%; prolateral trichobothrium missing on tibia 1, present on all other tibiae; tarsus 1 with ~30 pseudosegments.

Variation: Other male with entire clypeus and anterior side of ocular area brown. Tibia 1: 5.4.

Female: In general similar to male, without darkened clypeus. Tibia 1: 4.2. Epigynum, simple externally ( Fig. 61 View Figures 38–62 ); dorsal view as in Figures 82 View Figures 63–82 , 191 View Figures 190–194 .

Distribution: Known from type locality only ( Fig. 201 View Figure 201 ).

Material examined: Dominican Republic: Duarte Prov., Reserva Científica Loma Quita Espuela , 1♂, holotype above; same data, 1♂, 1♀ and one juvenile

(ZFMK, DR 23); same data, one juvenile, in pure ethanol ( ZFMK, DR 100-24 View Materials ) .
