New Neotropical species of the genus Austrotinodes Schmid (Trichoptera: Ecnomidae) Author Thomson, Robin E. Author Holzenthal, Ralph W. text Zootaxa 2010 2437 38 50 journal article 10.5281/zenodo.194845 8a7d135d-d925-4b89-8529-65bbab21374f 1175-5326 194845 Austrotinodes taquaralis , new species Fig. 6 Diagnosis. This species is most similar to A. belchioris , new species , and A. abrachium , new species . In A. taquaralis , the intermediate appendage is lacking the basoventral branch of A. belchioris but has instead a single basoventral seta. While the dorsal branch of the intermediate appendage in A. belchioris has 2 setae, there are 3–4 present in A. taquaralis . Additionally, in A. taquaralis , the membranous apical region of the phallus is shorter in proportion to the lateral process than in A. belchioris or A. abrachium . Description. Male . Forewing length 4.9–5.3 mm (n=6). Body sclerites brown, dorsum of head light brown with pale yellow and light brown setae; thorax light brown with pale yellow setae dorsally, light brown ventrally; leg segments with brown setae. Forewings covered with fine dark brown and pale yellow setae in a mottled pattern. Genitalia . Segment IX deeply divided, sternum elongated; in lateral view, enlarging apically, ventral margin slightly convex; in ventral view, apical margin convex. Phallic guide sclerotized, not highly elevated; in lateral view, base narrow, apex pointed, reaching tip of inferior appendage; in caudal view, with single indentation. Inferior appendages fused mesally, attached apicomesally on sternum IX; in lateral view, ovate; in ventral view, lateral lobes subquadrate, directed posterolaterally, posterior margin concave with central point. Tergum X divided into pair of semimembranous oval lobes, lobes bulbous, bearing dorsal setae. Preanal appendage long, surface setose, margin crenulated, parallel-sided, apex rounded. Intermediate appendage long, approximately 3/4 length of preanal appendage; in lateral view, curved; single; bearing 3–4 large spinelike setae apically and 1 seta basoventrally. Phallus with sclerotized phallobase and membranous apical region; lateral process elongate, bifid, dorsal branch long, wide, ventral branch short, narrow, dorsal branch with row of 2 subapical and 1 apical spines, ventral branch with 1 apical spine; without basomesal process.
