( Figs. 18–20 ) Diagnosis. Female: Gnathosoma : Palpal length about 1/4 length of gnathosoma. Dorsum : Coarse ornamentation on prodorsum and tergite D. Tergite C with three transverse rows of cells, grouped between setae c1 , and same number of cells per row (four), except for last (five). Setae v1 , sc2 , c1 , c2 and h unmodified in shape. Setae v1 as long as sc2 (~ 30). Setae c1 and c2 similar in length (~ 25), both longer than h (~ 17). Setae c1 inserted near midlength of tergite C. Setae d , e and f leaf-shaped. Setae d and f identical in shape (ensiform with two lateral veins) but slightly different in length (~ 36 and ~ 31, respectively) and width (~ 8 and ~ 10, respectively). Setae e linear-lanceolate in shape, shorter than d and f , but as long as h (~ 17). Setae f ~10 distant from each other, on rounded tubercles. Venter : Tegula truncate, slightly arched. Apodemes distinct, except for prosternal apodeme from level of apodemes 2 to sejugal apodeme. Apodemes 2 not fused to prosternal apodeme. Poststernal apodeme weakly bifurcated anteriorly. Legs : sensory cluster of tibiotarsus I complete. Seta tc” of tarsus II slender and serrate. Male & larva: unknown. FIGURE 18.

Apodemes 1 conspicuous, fused to anterior end of prosternal apodeme. Apodemes 2 short and not fused to prosternal apodeme. Prosternal apodeme conspicuous from junction with apodeme 1 to apodemes 2 and inconspicuous from that point to sejugal apodeme. Sejugal apodeme interrupted medially. Apodeme 3 extending diagonally from proximity of base of seta 3a to (but not laterally beyond) anterior margin of trochanter III. Apodeme 4 extending diagonally from posterior third of poststernal apodeme nearly to base of seta 3b . Poststernal apodeme bifurcated anteriorly.
