Triaenodes cuyotenango and a number of other species have a digitate dorsomesal process of tergum X, with tergum X having a rounded or truncate apex (T. mexicanus, T. peruanus, T. tuxtlensis and variants of T. delicatus). This new species can be separated from the others by its very long dorsomesal process.
Adult (male: n=2). Forewing length 5.6–6.3 mm, hind wing length 4.8–5.2 mm. Eye 0.42–0.43 mm wide. Antennal scape 0.46–0.47 mm long. Maxillary palp segment lengths (in mm): 0.26–0.32, 0.35–0.39, 0.51–0.52, 0.27–0.29, 0.48–0.53. Forewing golden brown, with narrow line of cream colored hairs along anal margin.
Male genitalia. Abdominal segment IX anterior margin slightly rounded, slightly produced anteroventrally; pleural region membranous, setose; tergum IX, in dorsal view, with posteromesal margin rounded, with pair of minute dorsomesal papillae; sternum IX in lateral view with posterior margin sinuate. Preanal appendage setose, about as long as wide, constricted basally, apex subacute. Dorsomesal process of tergum X digitate, originating basally, long, extending beyond apex of tergum X, with apical setae; tergum X, in dorsal view, with lateral margins subtriangular, apex slightly excavate medially; in lateral view, parallel sided, apex truncate, with lateral flange, apicolateral margins with microtrichia. Inferior appendage subquadrangular basally, setose, with long, tapering, apicoventral projection; recurved process gradually downturned, narrow, tapering throughout length, 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; phalicata troughlike, straight, narrow throughout length, apex with shallow cleft, phallotremal sclerite not evident.
