Theratta mannavan n. sp. Anilkumar, Wesener & Moritz

Figs 2–6

Diagnosis. Head pointed (Fig. 3A) rather than broad and slightly stout as in Theratta eravikulam n. sp. (Fig. 8A) and Theratta shola n. sp. (Fig. 10A). T. mannavan n. sp. shares with T. shola n. sp. the wave-like curve centrally on the posterior margin of the prozonites (Fig. 4A), while such a curve is absent in T. eravikulam n. sp. (Fig. 8E). Differs from T. eravikulam n. sp. and T. shola n. sp. by the absence of the line fold at the anterior region, separating the ganthochilarium from the rest of the head (Fig. 3F). T. mannavan n. sp. differs from T. eravikulam n. sp. by the mesal process and lamellar process of the anterior gonopod each being triangular distally (Fig. 5E), whereas these processes are rounder and broader in T. eravikulam n. sp. (Figs 9D, F). Posterior gonopod consisting of four podomeres (Fig. 6I), while it consists of six podomeres in T. eravikulam n. sp. (Fig. 9C) and T. shola n. sp. (Fig. 11F). T. mannavan n. sp. shows a genetic p-distance in the COI gene of 20.9 % to T. eravikulam n. sp. and 21. 7 % to T. shola n. sp. .
