Figures 1–30 , 372

TYPES: Male holotype and female allotype from Berlese and sifted leaf litter of a gallery forest at an elevation of 40 m at Reserve Prive Berenty , Forêt de Malaza , Mandrare River , 8.6 km 314° NW Ambosary, 25°0′28″S, 46°18′22″E, Toliara Province (6 February 2002, B.L. Fisher et al.) deposited in CASC ( PBI_OON 00036156 ). The species epithet, a noun in apposition, is taken from the Malagasy word for dog .

DIAGNOSIS: N. amboa can be differentiated from other Noideattella species by the following combination of characters: habitus dark red-brown, carapace pars cephalica and sides strongly granulate (figs. 4, 11, 12 ). Book lung covers small and round (figs. 2, 3). Sternum microsculpture finely reticulate distributed medially and in furrows (figs. 5, 16 ). Male paturon inner margin with modified seta of variable thickness ( figs. 17–19 ).

DESCRIPTION: Male (PBI_OON 0002013): Total length 1.4. Cephalothorax: Carapace dark red-brown. Sternum longer than wide, dark red-brown, furrow with rows of small pits, anterior margin with interrupted transverse groove (figs. 4, 5, 7, 11, 12 ). Mouthparts: Chelicerae, endites, labium dark red-brown. Abdomen: Ovoid. Dorsal scutum dark red-brown, middle surface smooth, sides smooth. Postepigastric scutum dark red-brown, long, semicircular, covering nearly full length of abdomen (figs. 1, 2). Male genital opening slightly protruded, epigastric scutum apodemes small, contiguous with anterior book lung opening, not connected by furrow. Posterior spiracles connected by groove (figs. 10, 20). Legs: Pale orange, without color pattern. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): tibiae: I, II p1-2-0; r1-2-0; IV p0-0-1; metatarsi: I, II p1-1-0; r1-1-0; IV p0-0-1. Tarsal organ with two sensilla visible. Genitalia: Epigastric region with sperm pore situated at level of anterior spiracles (fig. 20). Palp proximal segments pale orange; cymbium pale orange, with distal patch of setae; bulb pale orange. Embolus dorsal lamella with distal apophysis (figs. 27, 28), ventral lamella bifurcate (figs. 6, 8). Palp as in figures 25 and 26. Female (PBI_OON 0002013): Total length 1.6. As in male except as noted. Cheliceral paturon inner margin with scattered setae. Legs: Metatarsi III and IV ventral scopula absent. Leg spination: tibiae: I, II p1-2-0; r1-2-0; IV p0-0-1; metatarsi: I, II p1-1-0; r1-1-0; IV p0-0-1; leg IV: both spines considerably smaller than those of legs I, II; tibial spine same length as segment width, metatarsal spine longer. Trichobothria of metatarsus: I one, IV one. Genitalia: Genital opening slit shaped (fig. 21). Sperm sac papillae flat, extending less than half receptaculum length, concentrated in center. Apodemes A2 less than half receptaculum length (figs. 9, 10, 22), GAp process shaped like twisted tube (figs. 22, 23). Genitalia as in figures 9 and 10.

VARIATION: The book lung covers in some specimens are considerably reduced. Cheliceral paturon inner margin setae vary among specimens; some lack modified setae, while other specimens have a brush of modified seta ( figs. 17, 18 ). Male leg I and II spines on tibia and metatarsus vary considerably with very few specimens lacking spines. Embolar dorsal and ventral lamella apophyses shape and number vary among individuals. Female leg I: the tibia spination varies from three to two spines at both sides; leg II spination varies widely with some specimens without spines on tibia. The number of spines on metatarsus (2 pairs) is constant. Female genital receptaculum sclerotized portion variable in shape, apodeme bases vary in shape either by covering most of the receptaculum or being considerably shorter. The T-shaped lateral extension also varies in length. Embolic lamellae vary in shape and number; in some specimens the prolateral surface of the embolus presents a small tooth (fig. 6).
