Tolegnaro sagani   , new species

Figures 313–341, 377

TYPES: Male holotype and female allotype from Berlese and sifted leaf litter of a littoral rainforest at an elevation of 10 m at Forêt de Petriky , 12.5 km W Tolagnaro, littoral forest 25°3.73′S, 46°42.26′E, Toliara Province, 22 November 1998, B.L. Fisher, deposited in CASC ( PBI _ OON 00036154). The species epithet is in honor of the astronomer Carl Sagan   .

DIAGNOSIS: T. sagani   can be differentiated from other Tolegnaro species   by the following combination of characters: carapace surface smooth (figs. 316, 325); male cheliceral paturon inner margin with scattered setae; sternum without radial furrows between coxae I–II, II–III, III–IV, surface and furrows smooth, microsculpture absent (figs. 317, 327); leg spines present, one pair on metatarsi I and II; paturon distal region unmodified (fig. 319).

DESCRIPTION: Male (PBI_OON 0003282): Total length 1.40. Sternum microsculpture absent, anterior margin with continuous transverse groove (fig. 323), anterior margin unmodified (fig. 327). Mouthparts: Cheliceral paturon surface with scattered setae (fig. 319). Abdomen: Pedicel has a pair of triangular dorsal projections on its margin and a line of dorsal setae. Postepigastric area setae needlelike. Male genital opening slightly protruded and covered by a line of feathery seta, epigastric scutum apodemes large, near the anterior book lung opening and connected by a shallow groove (fig. 330). Legs: Yellow; tibia I with dorsal row of ridges. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): tibiae: I, II p1-1-0; r1-1-0; metatarsi: I, II p0-1-0; r0-1-0. Tarsi I to IV superior claw teeth not examined in detail. Trichobothria on tibiae: I three, IV three, trichobothria base longitudinally narrowed, aperture internal texture gratelike, hood covered by numerous low, closely spaced ridges. Tarsal organ with three sensilla visible. Genitalia: Palp proximal segments pale orange; cymbium pale orange (figs. 318–320), cymbium without distal patch of setae (fig. 306). Embolus dorsal lamella with three distal apophyses (figs. 340, 341), ventral lamella with at least two apophyses, one bifurcated (figs. 338, 339). Palp as in figures 336 and 337. Female (PBI_OON 0003282): Total length 1.56. As in male except as noted. Abdomen: Pedicel with pair of triangular dorsal projections on margin and line of dorsal setae. Legs: Tibia I Emerit’s glands absent. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): tibiae: I, II p1-1-0; r1-1-0; metatarsi: I, II p0-1-0; r0-1-0. Tarsi I to IV superior claw teeth not examined in detail. Genitalia: Genital opening slit shaped (fig. 331). Sperm sac secretory glands openings flat, extending over the receptaculum center. GAp process shaped as a twisted tube (figs. 332–334). Genitalia as in figures 321 and 322.

VARIATION: Male leg I spine number varies on the tibia from one to two pairs, tibia leg II spine number varies widely, some specimens do not have spines. Female leg II spine number varies, some specimens only have one spine on the prolateral side. The shape and number of embolar dorsal and ventral lamella apophyses varies among individuals (figs. 336, 339, 340).
