- Forewing M3 simple (Figs 3, 9, 75, etc.)................................................................... 8

3. Hypandrium with only the central sclerite, this with short caudo-lateral lobular processes and one central narrow elongate process having two small apical lobes (Fig. 326); phallosome as in figure 328..................... T. lamensuraensis n. sp.

- Hypandrium with two to four sclerites (Figs 308, 338, 365, 365 and 367); central sclerite of hypandrium and phallosome variable (Figs 310, 371 and 340)............................................................................. 4

4. Hypandrium of three sclerites, central sclerite with two pairs of posterior, acuminate processes, and a posterior median, elongate, acuminate process (Figs 308 and 365)................................................................. 5

- Hypandrium of two or four sclerites, the anterior-central sclerite with a pair of long acuminate, horn-shaped processes, strongly curved distally (Figs 338, 366, and 367); posterior sclerite with an acuminate or spatulate process............... 6

5. Central sclerite of hypandrium with median, posterior, long acuminate process, almost as long as the lateral ones (Fig. 365); phallosome with phallobase almost straight proximally, posterior endophallic sclerite sinuous distally, with strongly curved tapered distal process (Fig. 370)............................................................... T. furcata New

- Central sclerite of hypandrium with median, posterior, stout process, longer than the lateral ones (Fig. 308); phallobase curved proximally toward the mesal line; posterior endophallic sclerites almost straight distally, with curved tapered apical process and two curved anteapical small teeth (Fig. 310).............................................. T. furcatoides n. sp.

6. Hypandrium of two sclerites, acuminate processes of anterior sclerite each with a basal tooth; posterior sclerite with spatulate posterior process, dilated distally (Fig. 338); phallosome with side struts independent, each widened basally (Fig. 340)........................................................................................ T. leguizamoensis n. sp.
