TYPE: Male holotype, female allotype, male paratype, and 3 female paratypes from sifted leaf litter at P.N. Ranomafana, 2.3 km N Vohiparara, 21 ° 12.89S, 47 ° 23.09E, 1100 m, Fianarantsoa Province, Madagascar (28 Apr 1998, C. Griswold, D. Ubick), deposited in CAS (CASENT 9029655, PBI _OON 03078).

ETYMOLOGY: The species is named after the type locality.

DIAGNOSIS: The male of this species differs from other Malagiella by the combination of small size and the absence of lateral spines on the hind legs. The female differs from others in its species group in having a widely sinuous receptaculum, W/L 5 1.0– 1.2 (figs. 182–184, 375–378; map 4).

MALE (PBI_OON 03078) (figs. 117–120, 125–128, 133–139, 142–152, 157–172, 345– 354, 365–372, 476, 484; map 3): Total length 1.32 (1.26–1.32), carapace length 0.64 (0.60–0.66), width 0.55 (0.52–0.56), N 5 9. CEPHALOTHORAX: Carapace orangebrown, broadly oval in dorsal view, pars cephalica strongly elevated in lateral view (figs. 117, 347), anteriorly narrowed to about 0.64 times its maximum width, surface and sides of elevated portion of pars cephalica finely reticulate (fig. 118); lateral margin undulate, smooth; nonmarginal pars cephalica setae dark, present in U-shaped row (figs. 117–120). Clypeus length more than twice eye area length (fig. 117). Eyes medium sized, eye area width 0.36 carapace width, length 0.45 clypeus length (figs. 117, 120). Sternum infracoxal groove with opening only at posterior end (fig. 125) with median longitudinal groove weakly represented (fig. 126); sternal bristles long, straight (fig. 125). Mouthparts: Chelicerae with promarginal tooth and patch of largely retromarginal denticles (figs. 135, 136). Endites distally excavated, serrula present in single row (fig. 128); distomedian part with projection bearing dense scopula (fig. 127), distolateral part with swelling bearing serrula and three stout setae (figs. 127, 128). AB- DOMEN: Cylindrical, slightly compressed (figs. 352, 354). Book lung covers large, ovoid (fig. 370). Dorsal scutum strongly sclerotized, narrowed to 0.6 carapace width; fusion with epigastric scutum a rounded junction (figs. 142–144). Postepigastric scutum broadly rounded, extending to about 0.6 abdomen length. Spinnerets (fig. 149): ALS with three spigots (fig. 150), PMS with two spigots (fig. 151), PLS with three spigots (fig. 152). LEGS: Spination: femur I p0-1-0; tibiae: I v4-4-0, II v4-2-1, IV v0-0-2 (weak). GENITALIA: Epigastric region with sperm pore small, unmodified (fig. 148). Palpal bulb with dorsobasal indentation (figs. 157, 158, 365, 366, 371, 372), embolus sharply bent ventrally (figs. 159, 160); ventral prong long (fig. 169); embolar opening small (fig. 170), closer to retrolateral prong (fig. 172).

FEMALE (PBI_OON 03078) (figs. 121– 124, 129–132, 140–141, 153–156, 173–184, 355–364, 373–378, 464, 468, 469, 479; map 1, 2, 4): Total length 1.36 (1.36–1.48), carapace length 0.66 (0.66–0.70), width 0.58 (0.55–0.59), N 5 4. CEPHALOTHORAX: Carapace similar to male but with lower cephalon, much shorter clypeus (figs. 121– 124), and anteriorly narrowed to about 0.46 maximum width (fig. 124). Eyes medium sized; eye area about 0.45 carapace width, length 0.5 clypeus length (figs. 121, 124). Sternum with infracoxal groove opening only at posterior end (fig. 130). Mouthparts: endites without distal modifications (fig. 132). ABDOMEN: Pedicel tube short (fig. 363); scutum dorsal extension shorter than in male, about 0.4 pedicel diameters (fig. 362). Dorsal scutum covering about 0.7 abdomen length, 0.5 abdomen width. Spinnerets (fig. 153): ALS with three spigots (fig. 154), PMS with three spigots (fig. 155), PLS with five spigots (fig. 156). LEGS: Spination as in male (figs. 468, 469). GENITALIA: Postepigastric scutum weakly sclerotized, externally with round copulatory opening (figs. 176, 177), receptaculum strongly sinuous, W/L 5 1.0–1.2 (figs. 182–184, 375–378; map 4), enclosed in chitinized membrane (figs. 179– 181), rigidly attached to postepigastric scutum (figs. 182–184).
