Trite lineata Simon, 1885: 92 (Male holotype from Nouméa, New Caledonia, MCZ 21853, and female allotype from Yahoué, New Caledonia, 0–100 m, December 1986, N.L.H. Krauss, AMNH, examined); Berry et al. 1997: 132; Platnick 2014.

Additional material examined. NEW CALEDONIA: 1F, Rivière Bleue, 160 m, 22°06′13″S, 166°39′16″E, 6 March 1987, A. & S. Tillier, Forêt humide/alluvions [rainforest] ( MNHN); 1F, Rivière Bleue P6, Forêt dense [rainforest], Fogging, 21 October 1992, J. Chazeau, É. Guilbert, Bonnet de Larbogne ( MNHN).

Diagnosis. In comparison with the most similar T. pennata and T. planiceps , it can be distinguished by the longer embolus, longer RTA, and the shape of tegulum ( Figs 8–9 ). Epigyne with distinct posterior pocket ( Fig. 4 ), copulatory ducts shorter than in previous species ( Fig. 10 ), but slightly longer than in T. simoni . From T. planiceps , it differs also by the smaller size.

Description. Male holotype. Cephalothorax brown ( Figs 1–2 ). Eyes surrounded in dark brown, with anterior fringe of white and orange hairs. Sparse white hairs on the sides and on the anterior middle of thorax. Thorax with indistinct lines radiating from fovea. Clypeus light brown, narrower (24%) than AME diameter, covered with long, white hairs. Chelicerae brown, slender, with frontal spur and papillate anterior surface, fangs with distinctive protrusions ( Fig. 6 ). Promargin with single tooth, retromarginal tooth with 4 cusps. Endites light brown, with lateral outgrowth. Labium light brown, sternum greyish brown. Palps yellowish, femur with one dorsal spine ( Fig. 9 ). Tibial apophysis slender. Embolus long, set at 10 o ′clock at the bulbus ( Fig. 8 ). Legs I brown, distal tibiae and patellae lighter ( Fig. 2 ); ventral spination: pI: 2, tI: 2-2-2 (prolateral 1-1), mI: 2-2. Legs II greyish brown; ventral spination: pII: 0, tII: 2-2-2 (prolateral 1-1), mII: 2-2. Other legs brown, lighter distally. Abdomen brown with longitudinal whitish stripes along the sides and dorsally along the midline, covered with sparse white hairs. Venter greyish brown. Spinnerets brown.

Dimensions. CL 2.20, CW 1.64, CH 0.95, AL 2.14, AW 1.05, EFL 1.06, AEW 1.36, PEW 1.39, leg I: 6.23, leg II: 4.07, leg III: 4.02, leg IV: 4.65.

Female. Cephalothorax dark brown ( Fig. 3 ). Eyes surrounded in black. Thorax with indistinct lines radiating from fovea. Sparse white hairs on the sides, and in the middle of thorax. Clypeus brown, much narrower (16%) than AME diameter, covered with long, white hairs. Chelicerae brown, slender, with papillate anterior surface. Promargin with single tooth, retromarginal tooth with 4 cusps. Endites and labium brown, sternum greyish brown. Legs I brown, distal tibiae and patellae lighter; ventral spination: pI: 2, tI: 2-2-2 (prolateral 1), mI: 2-2. Legs II greyish brown; ventral spination: pII: 0, tII: 2-2-2 (prolateral 1-1), mII: 2-2 (prolateral 1-1). Other legs brown, lighter dorsally. Abdomen greyish brown with light patches, covered with sparse whitish hairs. Venter greyish brown with lighter stripes along sides. Wing-shaped margin of shallow depressions on the epigyne close to each other ( Figs 4 , 10 ). Copulatory ducts slightly oblique. Proximal part globular (secondary spermatheca), distal part duct-like with three loops ( Fig. 10 ). Spinnerets greyish brown.

Dimensions. CL 2.06, CW 1.56, CH 1.03, AL 2.67, AW 1.58, EFL 1.16, AEW 1.45, PEW 1.51, leg I: 5.83, leg II: 3.81, leg III: 3.76, leg: IV 3.35.
