Diagnosis. This new species belongs to A. (Atopsaura) longipennis group as by apicomesal projection of the first article of the inferior appendage. Atopsyche (Atopsaura) froehlichi sp. nov. is similar to A. (Atopsaura) plancki Marlier, 1964 & A. (Atopsaura) galharada Santos & Holzenthal, 2012 in filipod absence, in the slender and rounded apex of parapod, in the broad first article of inferior appendage with apicodorsal projection, and in simple phallic apparatus (without projections or processes attached). Atopsyche (Atopsaura) froehlichi sp. nov. is similar to A. (Atopsaura) plancki on coiled aedeagus of phallic apparatus, but the new species can be distinguished from it by a slender first article of inferior appendage, by the absence of apicoventral projection, and by apicoventral projection of beaks of phallic apparatus.

Description. Length of each forewing 0.9–1.02 mm (n=3) ( Fig. 6 ). Overall body color yellowish to light brown. Frons and vertex of head with yellow and light brown setae. Antennal scapes with some short light brown setae; pedicels yellowish, basal flagellomeres yellowish with light brown shadows, apical flagellomeres brown. Maxillary palps segments 1 and 2 with long brown setae. Dorsum of thorax without setae. Overall color of wing yellowish; setae of veins light brown setae. Forewing venation complete ( Fig. 6A ); R1 branched apically, covered with brown setae on pterostigma; stem of fork I equal to its length; fork II long, pediculate; stem of fork III shorter than its length; fork IV long, pedunculate; fork V long; discoidal cell long; stem of M almost straight between m-cu crossvein and first fork of M; Cu converging near fused anal veins, with crossvein at the apical region. Hind wing with Sc and R1 fused apically; forks I, III and V present, the first with stem shorter than its length, stem of fork III shorter than its length, stem of fork III very short; Cu2 long and almost straight; 1A absent; 2A long and curved ( Fig. 6B ). Rounded midlateral gland on sternum V ( Fig. 8F ). Sterna VI and VII each with posteromesal projections, lateral view ( Fig. 8E ); anterior projection covered by spine-like setae and about 2x longer than posterior; posterior projection covered by spine-like setae, broad, lateral view ( Fig.8E ). Male genitalia. Segment IX slender, curved at anterodorsal and posterodorsal margins, lateral view ( Figs. 7A , 8A ). Proctiger slender, constricted at anterior region, lateral view ( Fig. 7A ). Parapod in anterior half and slender in posterior half, with two dorsal projections at the middle, truncate at apex, lateral and ventral views ( Figs. 7A, 7D , 8D ). Filipod absent. Preanal appendage uniformly rounded, lateral view ( Fig. 7A ), with irregular margin, ventral view ( Fig.7D ). Inferior appendage, first article wide, slightly broader at apex, apicomesal projection wide at base and acute at apex, with apicodorsal projection, lateral view ( Figs. 7A, 7C , 8B ); second article wide at base and slightly thinner at apex, lateral and ventral views ( Figs. 7A, 7B , 8C ). Phallic apparatus simple, phalloteca wide, beaks with apicoventral projection, lateral view ( Figs.7C, 7E ); aedeagus coiled basally, upcurved posteriorly, with upcurved apex, lateral view; coiled basally and straight in posterior half, dorsal view ( Figs. 7C, 7E ).

Holotype male. BRAZIL: Rio Grande do Sul: Cambará do Sul, Parque Nacional Aparados da Serra , P 3 (sede), 13.i.2013, Light Pan Trap, M Carneiro col. ( MZUSP).

Paratypes. Same data as holotype, except 2 males ( UFBA) .

Distribution ( Fig. 20A ). Brazil (RS, Atlantic Forest domain).

Remarks. This new species is placed in A. (Atopsaura) longipennis Group by the apicomesal projection of the first article of the inferior appendage. Atopsyche (Atopsaura) froehlichi sp. nov. is similar toAtopsyche (Atopsaura) plancki in the wide first article of the inferior appendage, but differs in thickness, in the absence of the apicoventral projection, and in the apicodorsal projection of the first article of the inferior appendage.

Etymology. This new species is named in honor of Prof. Dr.Cláudio Froehlich for his distinguished contribution to our knowledge on the Neotropical aquatic insects, and the guidance of the next generation of aquatic entomologists.
