Diagnosis. Female: Gnathosoma : Palpal length about 1/4 length of gnathosoma. Dorsum : Reticulate ornamentation on prodorsum. Tergites C and D with reticulate ornamentation. Tergite C with four transverse rows of well-defined cells grouped between setae c1 , and same number of cells per row (four). Tergite D with four transverse rows of well-defined cells grouped between setae d . Setae v1 , sc2 , c1 , c2 and h unmodified in shape. Setae v1 shorter than sc2 (~ 26 and ~39, respectively). Setae c1 longer than c2 (~ 25 and ~18, respectively). Setae c1 inserted near midlength of tergite C. Setae d , e and f leaf-shaped. Setae d and f similar in shape (ensiform with two lateral veins), length (~ 45) but slightly different in width (~ 5 and ~4, respectively). Setae e asymmetrical in shape, width (~28), shorter than d and f , but longer than h (~ 32 and ~18, respectively). Setae f ~17 distant from each other, on rounded tubercles. Venter : Tegula truncate, slightly arched posteriorly. Apodemes distinct, except for prosternal and poststernal interrupted. Apodemes 2 not fused to prosternal apodeme. Poststernal apodeme bifurcated anteriorly. Legs : sensory cluster of tibiotarsus I complete. Seta tc” of tarsus II distinctly serrate and robust. Male & larva: unknown. FIGURE 105.
