Etymology. The specific epithet is an arbitrary combination of letters incorporating the Greek word "telytokos", in reference to the type of parthenogenesis that produces only female offspring.

Diagnosis. This species can be distinguished by the following combination of characters: (i) forewings not reaching the third abdominal tergite ( Fig. 1View FIGURES 1 – 5); (ii) forewings presenting dorsal field light yellow with dark brown spot and lateral field dark brown ( Fig. 2View FIGURES 1 – 5); (iii) supraanal plate with straight posterior margin ( Fig. 12View FIGURES 6 – 17); (iv) lateral lobes of pronotum dark brown with stripe extending from antero-ventral margin to the central portion of dorsal lobe ( Figs. 6, 7View FIGURES 6 – 17).

Eggs. Clear, yellow and elongated ( Fig. 15View FIGURES 6 – 17) with rounded edges, with one being smooth and another sculptured ( Figs. 16, 17View FIGURES 6 – 17). The micropylar region was not identified. Average length was 2.05 mm (n = 4).

Karyology. 2 n = 18 (Fig. 18). Fourth, fifth and ninth chromosome pairs submetacentric; others metacentric. The mechanism of sex determination was not evaluated because males of this species are unknown. The sixth chromosome pair has pronounced heteromorphism and is associated with the nucleolus organizing regions (Figs. 19, 20).
