Fig. 17

Of those species with an apicoventral projection on the inferior appendage and a bifid dorsomesal process on tergum X ( T. chirripo , T. clauseni ), this is the only one in which the dorsomesal process is completely divided to its base.

Adult (male: n=2). Forewing length 6.1 mm, hind wing length 4.8–4.9 mm. Eye 0.34– 0.39 mm wide. Antennal scape 0.39–0.43 mm long. Maxillary palps broken. Forewing pale yellow, denuded.

Male genitalia. Abdominal segment IX anterior margin slightly rounded, produced anteroventrally; pleural region membranous, setose; tergum IX, in dorsal view, with posteromesal margin truncate, dorsomesal papillae not evident; sternum IX in lateral view with posterior margin slightly sinuate. Preanal appendage setose, about as long as wide, constricted basally, apex subacute. Dorsomesal process of tergum X completely divided, originating basally, short, less than half length of tergum X, with apical setae; tergum X, in dorsal view, with lateral margins subtriangular, apex strongly excavate medially; in lateral view, triangular, tapering to apex, apicolateral margins with microtrichia. Inferior appendage subquadrangular basally, setose, with short, tapering, apicoventral projection; recurved process gradually downturned, narrow, tapering throughout length, but constricted subapically, apex sharply attenuate; apicomesal lobe heavily setose, elongate, narrow, slightly broadened subbasally. Phallobase small, triangular, endothecal membranes prominent, highly convoluted, with pair of parameres, parameres subequal, long, gently curved, tapering, apices slightly bent; phalicata troughlike, gently curved, narrow throughout length, apex cleft, phallotremal sclerite small, u­shaped.
