Noideattella tsiba , new species

Figures 141–170 , 376

TYPES: Male holotype and female allotype from Berlese sample of sifted leaf litter of a tropical dry forest at an elevation of 375 m at Forêt de Binara , 7.5 km 230° SW Darania, 13°15′18″S, 49°37′E, Antsiranana Province (1 December 2003, Fisher-Griswold Arthropod Team) deposited in CASC ( PBI_OON 00036159 ). The species epithet, a noun in apposition, is taken from the Malagasy word for the Coquerel’s dwarf lemur .

DIAGNOSIS: N. tsiba can be differentiated from other Noideattella species by the following combination of characters: habitus color pale orange; abdomen dorsal surface with a pair of dark marks posteriorly (figs. 141, 143); carapace pars cephalica and sides strongly granulate (figs. 159, 161); sternum furrows with row of large pits, surface coarsely reticulate, microsculpture (visible best with light microscopy) medially and in furrows (figs. 145, 162); book lung covers small, and ovoid (figs. 142, 143); color of legs homogeneous.

DESCRIPTION: Male (PBI_OON 0003545): Total length 1.4. Cephalothorax: Carapace pale orange. Sternum longer than wide, pale orange, anterior margin with continuous transverse groove (figs. 160, 162). Mouthparts: Chelicerae, endites, and labium pale orange. Paturon inner margin with scattered setae and without modified seta (fig. 147). Abdomen: Ovoid. Dorsal scutum pale orange, middle surface smooth, sides smooth. Postepigastric scutum pale orange, long, semicircular, covering nearly full length of abdomen (figs. 141–143). Male genital opening slightly protruded, epigastric scutum apodemes small, separated from the anterior book lung opening and connected by a shallow furrow. Posterior spiracles connected by a groove ( fig. 155 ). Legs: Yellow, without color pattern. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): tibiae: I p2-1-1; r2-1-1; II p1-1-1; r1-1-1; IV p0-0-1; metatarsi: I, II p1-1-0; r1-1-0. Tarsi I to IV superior claw teeth not examined in detail. Genitalia: Epigastric region with sperm pore situated at level of anterior spiracles ( fig. 155 ). Palp proximal segments yellow; cymbium yellow, with distal patch of setae; bulb yellow (figs. 146, 148). Embolus dorsal lamella with one large apophysis (fig. 164), ventral lamella with two apophyses (fig. 163). Palp as in figures 163 to 165. Female (PBI_OON 0003545): Total length 1.6. As in male except as noted. Legs: Metatarsi III and IV without weak ventral scopula. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): tibiae: I, II p2-1-1; r2-1-1; IV p0-0- 1; metatarsi: I, II p1-1-0; r1-1-0. Trichobothria of metatarsus: I one, IV one. Tarsal organ with three sensilla visible. Genitalia: Genital opening slit shaped ( fig. 156 ). GAp process shaped as a twisted tube. Sperm sac secretory gland openings flat, extending less than half the receptaculum length and concentrated in the center ( figs. 151–153 ). Genitalia as in figures 149 and 150.

VARIATION: Leg I tibia spine numbers vary among specimens from four to three on both sides.
