Noideattella tany , new species

Figures 201–230 , 375

TYPES: Male holotype and female allotype from Berlese sample of sifted leaf litter of a littoral rainforest at an elevation of 30 m at Forêt Analabe, 30.0 km 72° ENE Daraina, 13°5′S 49°54′30″E, Antsiranana (27 November 2003, Fisher-Griswold Arthropod Team) deposited in CASC ( PBI_OON 00036161 ). The species epithet, a noun in apposition, is taken from the Malagasy word for earth, soil, land, or country .

DIAGNOSIS: N. tany can be differentiated from other Noideattella species by the following combination of characters: habitus pale orange; abdomen cylindrical, rounded posteriorly; postepigastric scutum pale orange, long narrow rectangle; carapace surface only slightly elevated and sides granulate (figs. 201, 202); ocular area narrow, slightly higher than the clypeus height (fig. 207); embolus dorsal lamella curved (figs. 227, 228); book lung covers large and ovoid; male paturon anterior surface with gland openings (visible only with SEM) (figs. 221–223).

DESCRIPTION: Male (PBI_OON 0003563): Total length 1.4. Cephalothorax: Carapace pale orange. Sternum longer than wide, pale orange, anterior margin with continuous transverse groove, furrows with rows of large pits, microsculpture medially (observed better with SEM) (figs. 205, 219, 220). Mouthparts: Chelicerae, endites, and labium pale orange. Cheliceral paturon inner margins lack modified setae. Sternum anterior margin with interrupted transverse groove ( fig. 216 ). Abdomen: Dorsal scutum pale orange, middle surface reticulate, sides reticulate. Male genital opening slightly protruded, epigastric scutum apodemes small, separated from the anterior book lung opening and not connected by a furrow. Posterior spiracles connected by a groove ( fig. 212 ). Legs: Pale orange, without color pattern. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): tibiae: I, II p2-1-1; r1-1-1; IV p0-0-1; metatarsi: I, II p1-1-0; r1-1-0. Tarsal organ with two sensilla visible. Genitalia: Palp proximal segments pale orange; cymbium pale orange, with distal patch of setae; bulb pale orange (figs. 206, 208). Embolus dorsal lamella with one distal apophysis, bifurcate at the apex (fig. 229), ventral lamella with at least three apophyses (fig. 230). Palp as in figures 224, 225, 227–230. Female (PBI_OON 0003563): Total length 1.7. As in male except as noted. Legs: Tibia I Emerit’s glands absent, metatarsi III and IV weak ventral scopula absent. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): tibiae: I, II p2-1-1; r1-1-1; IV p0-0-1; metatarsi: I, II p1-1-0; r1-1-0. Trichobothria of metatarsus: I one, IV one. Genitalia: Epigastric region with sperm pore situated at level of anterior spiracles ( fig. 212 ). Genital opening slit shaped ( fig. 211 ). Sperm sac secretory glands openings flat, extending all over the receptaculum posterior surface. GAp process shaped as a twisted tube ( figs. 213, 214 ). Genitalia as in figures 209 and 210.

VARIATION: Male paturon lacks modified setae; however, some specimens have two long and thick setae at the apex of the paturon (figs. 221–223). The extension of the carapace surface texture varies from all over the cephalothorax to only at the sides. Sternum furrows can have either rows of large pits or reticulate microsculpture, and sternum also varies medially from finely reticulated to smooth. In some specimens the eyes are slightly reduced.
