Type material.

Holotype female (MHNG): Karteri Valley, Tamil Nadu, India [11°18'N, 76°48'E], Voy. Carl et Escher.

Diagnosis.

The species can be separated from other species by the raised epigynal plate and very large posterodorsal fold (Figs 87-88). Males unknown.

Holotype:Color: carapace uniformly yellow-brown; sternum pale yellow; chelicerae pale yellow with darker infuscations anteriorly; maxillae pale yellow; labium pale yellow-brown; abdomen dorsally yellow brown with darker flecks medially and laterally, festoon prominent; ventrally pale yellow-brown; legs with femora, patellae and tibiae I-IV clearly annulated, yellow-brown, darkening distally; annulations not encircling legs entirely. Cephalothorax:setae long and thin; 0.81 times longer than broad; fovea longitudinal, broad, somewhat shallow. Eyes:AER nearly straight; PER recurved; PME larger than AME, PLE largest, ALE smallest; eye group width 1.53; eye diameters, AME 0.17, ALE 0.10, PME 0.25, PLE 0.29; PME-PLE 0.34, ALE-PLE 0.33, AME-PME 0.08; ocular quadrangle AME-AME 0.21, PME-PME 0.63; clypeus 0.06 high. Mouthparts:chelicerae with a few stout setae medially and anteriorly; lateral boss present, smooth; promargin with 3 teeth, retromargin with 2 teeth; maxillae longer than broad, with tuft of conspicuous setae distally; labium distally rounded. Sternum:0.94 times longer than broad, posteriorly indented. Pedipalp:claw present with c. 6 teeth. Legs:leg I much shorter than legs II, III and IV; leg formula 32=41; scopulae absent on all legs; tarsus I–IV with strong claw tufts; pr claws with c. 10 teeth, rl claw with none; spination: leg I, Fm pr 1 –1– 0, d 1 –1– 1, rl 0; Ti v 2 –2– 2; Mt 2-2; Ti and Mt I and II with strong spines; leg II, Fm pr 0, d 1 –1– 1, rl 0; Ti 2 –2– 2; Mt 2-2; leg III, Fm pr 0, d 1 –1– 1, rl 0; Ti 1 –0– 0; Mt 1-0; leg IV, Fm pr 0, d 1 –1– 1, rl 0; Ti v 1-0 L, 0 R; Mt 0. Abdomen:terminal setal tufts present. Epigyne:lateral lobes not distinct, medial arch anterior to w-shaped area, median area in between this raised, small quadrangular area in center of plate, epigynal pockets present; internally, large posterodorsal fold present, and as this is the type of a rare specimen, we chose not to dissect it, spermathecae seen through integument are oblong and narrow, fertilization ducts located posterolaterally (Figs 87-88).
