Diagnosis. This new species differs from its congeners by the following characteristics: preanal appendage ventral process short, ending before the base in ventral view; distal margin of segment IX with three acute processes, one medial and two laterally;segment X thin in lateral view,and inferior appendage basoventral lobe ½ shorter than subapicodorsal lobe. Neoathripsodes froehlichi sp. nov. differs fromN. anomalus Holzenthal, 1989 by the presence of the following characteristics: three large, acute processes on the posterior margin of segment IX in dorsal view (narrow in N. anomalus ), and segment X thinner in lateral view, and larger in dorsal view. than N. anomalus . In addition, Neoathripsodes froehlichi sp. nov. distinguished from N. holzenthali Dias, Quinteiro & Calor, 2015 by the preanal appendage bearing a broad dorsal process, and a short ventral process in lateral view (narrowest and longest inN. holzenthali ); presence of bifid parameres (single in N. holzenthali ), and phallotremal sclerite broader than N. holzenthali in lateral view.

Description. Adult male. Forewing length 5.5–6.0 mm (n=6). Hind wing length 5.0– 5.5 mm (n=6). Head midcranial sulcus absent. Thorax brown, forewing vein R 1 becomes thickened, especially after discoidal cell; veins R 2+3 and R 4+5 very thickened; vein Cu1b little thickened; crossveins r-m and m-cu present ( Fig. 9A ). Hind wing vein Sc thickened; crossvein r-m absent ( Fig. 9B ). Abdomen, segment IX pointed mesoapically, with process pointed lateroapically in both sides in posterior margin in dorsal view ( Fig. 10B ); broad in posteroventral region, narrow in dorsal region; distal margin sinuous in lateral view ( Fig. 10A ). Segment X bifid at apex; enlarged at basal and middle region, narrow at apex in dorsal view ( Fig. 10B ); thin, apex rounded in lateral view ( Fig.10A ). Preanal appendage triangular in dorsal view ( Fig. 10B ); oval in lateral view ( Fig. 10A ). Inferior appendage subapicodorsal lobe with apex robust; basoventral lobe 1⁄2 shorter than subapicodorsal lobe; inferior margin with process pointed in basal region in lateral in view ( Fig. 10A ); subapicodorsal lobe digitated; basoventral lobe short ending before base; harpago posterior margin setose in ventral view ( Fig. 10D ). Phallic apparatus phallobase well developed; phallicata membranous dorsally; phallotremal sclerite broad, triangular, ventral margin sinuous; parameres bifid, apical spines in each lobe in lateral view ( Fig. 10C ).

Holotype male. BRAZIL: São Paulo, Pico do Marins, Serra da Mantiqueira , trilha, 22°30’09”S, 45°07’16”W, el. 2421 m, entomological net, 19.i.2006, AR Calor, LC Pinho, & FO Roque cols. ( MZUSP).

Paratypes. Same data as holotype, except 1 male ( MZUSP) , 2 males ( UMSP) , 2 males ( UFBA) .

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

Remarks. Neoathripsodes froehlichi sp. nov. is described based on three specimens exclusively collected in the Pico do Maris, between Minas Gerais and São Paulo states, southeastern Brazil. Pico do Maris is a fragment of Atlantic Forest and it is in the Mantiqueira mountain range. Its summit is 2.421 meters above sea level, making it the 26 th- highest peak in Brazil. Formed by a large rocky massif with steep walls.

Neoathripsodes froehlichi sp. nov. is the third species of the genus described and the species with the highest recorded altitude (2.421 m a.s.l.), N. anomalus and N.holzenthali are recorded in 1.180 m and 833 m a.s.l., respectively. All Neoathrispodes species are exclusively recorded in the Atlantic Forest domain.

Etymology. This new species is named in honor Prof. Dr. Claudio Gilberto Froehlich for his great contributions to studies of Neotropical aquatic insects.
