Neomabra Dognin, 1905, stat. rev., is revalidated, including two species: N. nitidalis Dognin, 1905, comb. rev. and N. serratilinealis (Lederer, 1863), comb. n. Bocchoropsis Amsel, 1956, syn. n. is a junior synonym of Haritalodes Warren, 1890, including two species: H. derogata (Fabricius, 1775) and H. pharaxalis (Druce, 1895), comb. n.

Abstract Three new species of Hapigia Guenée, 1854, from Brazil and Ecuador, are described: H. postpallida Becker sp. nov., H. violacea Becker, sp. nov. and H. violetta Becker, sp. nov.

ABSTRACT The Notodontidae genus Xylodonta Becker, 2014 is represented by 20 species, five of them new, four from Brazil: X. giffordi sp. n., X. imitans sp. n., X. ochreibasis sp. n., and X. robustoides sp. n.; and one from Guatemala: X. monzoni sp. n.; one species: X. pythia (Druce, 1894) stat. rev., is removed from the synonymy with X. xylinata (Walker, 1865), three: X. placida (Schaus, 1911) syn. n. and X. riparia (Druce, 1906) syn. n. (=X. guarana (Schaus, 1892)) and X. patrickgoodwilliei Chacón, 2017 syn. n. (=X. xylinata (Walker, 1865)) are synonymized; and one: N. russula (Dognin, 1909) comb. n. is transferred to Nycterotis Felder. Diagnosis and illustrations of adults and genitalia of all species recorded from Brazil are provided to allow their identification.

ABSTRACT Bardaxima Walker, 1858 includes 12 species, eight of them occurring in Brazil. The Brazilian species are treated here, including diagnoses and illustrations of both adults and genitalia to allow their identification: B. donatian (Schaus), B. fulgurifera (Walker, 1869), stat. rev. (= demea (Druce, 1895)); B. ionia (Druce, 1900) (= albolimbata (Dognin, 1909), syn. nov., B. ambigua (Dyar, 1908), syn. nov., B. metcalfi (Schaus, 1928), syn. nov.); B. lucilinea Walker, 1858; B. marcida (C.

Bardaxima perses Druce, 1900 is transferred to Elasmia Möschler, 1883 as a new combination, Elasmia perses (Druce, 1900). Stragulodonta gen. nov. is proposed to accommodate Heterocampa stragula Möschler, 1883, comb. nov. (= belua (Draudt, 1932), syn. nov.).

Three new species of Saturniidae from Central Brazil are described: Cicia norape Becker (Ceratocampinae), Dysdaemonia concisa Becker, and Rhescyntis reducta Camargo & Becker (Arsenurinae).

The New World taxa of the pantropical Chlidanotinae tribe Chlidanotini (Lepidoptera, Tortricidae) are reviewed. Twenty seven species and two subspecies are described as new: Auratonota auriginea, A. badiaurea, A. clasmata, A. exoptata and A. tessellata (Brazil); A. paidosocia and A. spinivalva cubana (Cuba); A. cataponera, A. flora, A. foederata, A. monochroma, A. moronana, A. nugax, A. petalocrossa maldonada, A. splendida, A. stigmosa and A. virgata (Ecuador); A. effera, A. oxytenia, A. serotina and A. spinivalva spinivalva (Mexico); A. magnifica (Venezuela); Heppnerographa brasiliana and H. lapilla (Brazil); H. ardea, H. carchiana and H. ecualorica (Ecuador).
