Figures 257–284 , 375

TYPES: Male holotype and female allotype from Berlese and sifted leaf litter of a tropical dry forest at an elevation of 325 m at Reserve Speciale d’Ambre , 3.5 km 235° SW Sakaramy, 12°28′8″S, 49°14′32″E, Antsiranana Province, 26–31 January 2001, Fisher-Griswold Arthropod Team, deposited in CASC ( PBI_OON 00003275 ). The species epithet, a noun in apposition, is taken from the Malagasy word for a dugout canoe or any small boat .

DIAGNOSIS: N. lakana can be differentiated from other Noideattella species by the following combination of characters: habitus color dark red-brown, body length 2.1 to 2.4 mm; carapace surface of elevated portion of pars cephalica strongly granulate, sides granulate (figs. 260, 275, 276); sternum furrows with row of large pits, surface coarsely reticulate, with microsculpture medially and in furrows (fig. 277); book lung covers large and elliptical (figs. 258, 259).

DESCRIPTION: Male (PBI_OON 0003462): Total length 2.1. Cephalothorax: Carapace dark red-brown, sternum longer than wide, dark red-brown, anterior margin with continuous transverse groove ( fig. 273 ). Mouthparts: Chelicerae, endites, and labium dark red-brown, paturon inner margin with scattered setae (fig. 263). Abdomen: Ovoid. Book lung covers large, elliptical. Dorsal scutum dark red-brown, middle surface smooth, sides smooth. Postepigastric scutum orange-brown, long, semicircular. Male genital opening slightly protruded, epigastric scutum apodemes small, separated from the anterior book lung opening and connected by a furrow. Posterior spiracles connected by a groove ( fig. 268 ). Legs: Orange-brown, without color pattern. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): tibiae: I, II p3-1-1; r2-1-1; IV p0-0-1; metatarsi: I, II p1-1-0; r1-1-0. Tarsal organ with two sensilla visible. Genitalia: Epigastric region with sperm pore situated at level of anterior spiracles ( fig. 268 ). Palp proximal segments pale orange; cymbium pale orange, with distal patch of setae; bulb pale orange (figs. 262, 264). Embolus dorsal and ventral lamellae with at least three distal apophyses each (figs. 281–284). Palp as in figures 279 and 280. Female (PBI_ OON 0003462): Total length 2.4. As in male except as noted. Legs: Metatarsi III and IV weak ventral scopula absent. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): tibiae: I, II p3-1-1; r3-1-1; IV p0-0-1; metatarsi: I, II p1-1-0; r1-1-0. Trichobothria of metatarsus: I and IV one. Genitalia: Genital opening slit shaped ( fig. 267 ). Sperm sac secretory glands openings flat, extending all over the receptaculum posterior surface. GAp process shaped as a twisted tube ( figs. 269–271 ). Genitalia as in figures 265 and 266.
