D07687C5FF8BFFBF27320C465BBC7671.taxon	discussion	Triaenodes delicatus is a highly variable species, especially in the structure of the apex of tergum X. The latter shows much intraspecific variation, even among individuals collected at the same time and place (Fig. 12). The apex of tergum X can range from acute and slightly upturned (Fig. 11 A) to rounded (Fig. 12 F) or more truncate (Fig. 12 E), with (Figs. 12 B, E) or without a small point. Otherwise, the species is quite generalized in its genitalia, perhaps most similar to T. peruanus, from which it can be separated by the overall shape of segment X, which is rounded apically and broader basally. It also bears some resemblance to T. nicaraguensis, which may be nothing more than another variant. However, the dorsomesal process of tergum X is much longer in T. nicaraguensis than in T. delicatus, and the recurved process of the inferior appendage is wider. Until more Triaenodes are collected from Nicaragua, we choose to recognize the Nicaraguan species as distinct from T. delicatus.	en	Holzenthal, Ralph W., Contents, Trond Andersen Table Of (2004): The caddisfly genus Triaenodes in the Neotropics (Trichoptera: Leptoceridae).

D07687C5FF8EFFBF273209E358B671BE.taxon	description	Fig. 13 Phenotypically, this species is very similar to T. mexicanus, the only distinctive character separating them being the rounded (T. mexicanus) or slightly excavated (T. flintorum) apex of tergum X. They are perhaps most similar in sharing the cleft apex of the phalicata. There are a number of smaller differences, but since so little material is available (one specimen of each species), it is impossible to determine whether this represent variation within a single species or not. Until more material is available for study, we prefer to assign these specimens to different species having no evidence of intermediate forms. Adult (male: n = 1). Forewing length 5.9 mm, hind wing length 4.8 mm. Eye 0.42 mm wide. Antennal scape 0.45 mm long. Maxillary palp segment lengths (in mm): 0.26, 0.39, 0.45, 0.23, 0.55. Forewing golden brown, with narrow line of cream colored hairs along anal margin. Male genitalia. Abdominal segment IX anterior margin nearly straight, 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 sinuate.

Dorsomesal process of tergum X digitate, originating basally, long, extending to apex of tergum X, with apical setae; tergum X, in dorsal view, with lateral margins subtriangular, apex slightly excavate medially; in lateral view, triangular, apex rounded, 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, parallel sided. Phallobase small, triangular, endothecal membranes prominent, highly convoluted, with pair of parameres, parameres subequal, long, straight, tapering, apices more heavily sclerotized; phalicata troughlike, straight, narrow throughout length, apex cleft, phallotremal sclerite small, u­shaped.	en	Holzenthal, Ralph W., Contents, Trond Andersen Table Of (2004): The caddisfly genus Triaenodes in the Neotropics (Trichoptera: Leptoceridae).

D07687C5FF8FFFBE2732096B5D9172D6.taxon	description	Fig. 14 This is a distinctive species among those that lack the apicoventral projection on the inferior appendage. It is most similar to T. morai in the possession of a spatulate dorsomesal process of tergum X, but differs from that species in its much larger size (7.4 mm vs. 5.3 mm forewing length in T. morai), by having 2 instead of 3 parameres, and by having both shorter preanal appendages and apex of tergum X. Adult (male: n = 1). Forewing length 7.4 mm, hind wing length 5.4 mm. Eye 0.38 mm wide. Antennal scape 0.38 mm long. Maxillary palp segment lengths (in mm): 0.26, 0.35, 0.50, 0.27, 0.65.

D07687C5FF83FFB2273209935B8871BE.taxon	description	Fig. 19 This is a very distinctive species in a number of features. First, like several other Neotropical Triaenodes, it lacks an apicoventral process on the inferior appendage, but in this species the base of the inferior appendage is especially heavily sclerotized and setose. In addition, the broad, flat recurved process of the inferior appendage and the long, thin, subapically curved pair of parameres, in addition to a third paramere, render it distinct. Adult (male: n = 1). Forewing length 5.0 mm, hind wing length 3.9 mm. Eye 0.31 mm wide. Antennal scape 0.34 mm long. Maxillary palp segment lengths (in mm): 0.23, 0.29, 0.34, 0.21, segment V missing.
