Silhouettella perismontes, new species Figures 17–24, 41, 42, 99 TYPES: Male holotype and female allotype from Berlese and sifted leaf litter of a tropical dry forest at an elevation of 300 m, Parc National d’Andohahela, Forêt d’Ambohibory, 1.7 km 61° ENE Tsimelahy, 36.1 km 308° NW Tolagnaro, 24°55′48″S, 46°38′44″E, Toliara Province, Madagascar (16–20 June 2002, B.L. Fisher et al.), deposited in CASC (PBI_OON 36176). ETYMOLOGY: The species epithet, a noun in apposition, is dedicated to first author’s dear friends Fernando Peris and Adriana Montes. DIAGNOSIS: S. perismontes can be differentiated from S. curieusei and S. perisalma by the body color and legs pale orange (figs. 1–3, 9–11, 17–19); from S. betalfa, S. osmaniye, and S. tomer by lacking a lateral protuberance on the dorsal lamella middle section (Saaristo, 2007: “X” in figs. 93B, 99B; Topçu et al., 2012: fig. 5). Unique diagnostic features include male embolus, dorsal and ventral lamella teeth or coils absent and bent at a right angle (figs. 20, 22). DESCRIPTION: Male (PBI_OON 36235). Total length 1.35. Cephalothorax: Carapace pale orange, pars cephalica flat in lateral view, posterolateral edge without pits. Sternum pale orange, surface smooth, microsculpture absent, anterior margin unmodified. Mouthparts: paturon inner margin with brush (figs. 17–19). Eyes six, well developed, ALE, PME subequal, larger than PLE, all eyes oval; posterior eye row recurved from above, straight from front; ALE separated by their radius to diameter, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius (figs. 17, 21). Endites distally excavated, anteromedian tip unmodified, posteromedian part unmodified, same as sternum in sclerotization. Pedicel tube short, ribbed, scutopedicel region unmodified, scutum not extending far dorsal of pedicel, plumose hairs absent, matted setae on anterior ventral abdomen in pedicel area absent (fig. 17). Abdomen: Cylindrical. Book lung covers elliptical large almost half receptaculum length (figs. 18, 41). Postepigastric area setae light. Legs: Pale orange, without color pattern. Leg spines absent (fig. 42). Tarsi I to IV superior claws tooth not examined in detail. Trichobothria not examined. Genitalia: Palp proximal segments pale orange (figs. 20, 22); tibia trichobothria not examined; cymbium pale orange. Embolic lamellae not examined with SEM. Palp as in figures 20 and 22. Female: (PBI_OON 3558). Total length 1.7. As in male except as noted. Cephalothorax: Female palp spines absent. Abdomen: Postepigastric scutum not fused to epigastric scutum (fig. 41). Legs: Tarsi I to IV superior claws tooth not examined in detail. Trichobothria not examined. Genitalia: Receptaculum length approximately ⅓ of its width. Papillae field visible with light microscopy as disperse black dots. Female genitalia as in figures 23 and 24. DISTRIBUTION: Endemic to Madagascar (fig. 99). MATERIAL EXAMINED: N = 10. MADAGASCAR: Toliara: Parc National d’Andohahela, Forêt d’Ambohibory, 1.7 km 61° ENE Tsimelahy, 36.1 km 308° NW Tolagnaro, tropical dry forest, 300 m, -24.93000°, 46.64555°, Jan. 16, 2002 to Jan. 20, 2002, B.L. Fisher et al., 2♀ Paratype (CASC PBI _ OON 3558); 2♂, 4♀, 8 mixed (CASC PBI _ OON 36235).
