Redescription and review of the Neotropical genus Carohamilia Dyar, 1940 (Lepidoptera: Cossidae: Zeuzerinae).

Based on the study of type specimens, we provide a redescription of the little known tropical genus of Cossidae (Lepidoptera), Carohamilia Dyar, 1940 (type species - Carohamilia ophelia (Schaus, 1921)). We establish the new combinations: Carohamilia masoni (Schaus, 1894), comb. n., Carohamilia terrafirma (Schaus, 1911), comb. n., Carohamilia poam (Dyar, 1918), comb. n., Schreiteriana lineaeplena (Dognin, 1911), comb. n., and a new synonym: Schreiteriana lineaeplena (Dognin, 1911) = Schreiteriana urcuchillay Yakovlev, Penco and Witt, 2017, syn. n.

Two new species of the genus Givarbela Clench, 1957 (Lepidoptera: Cossidae: Hypoptinae) from South Neotropics.

Givarbela steinbachi was described as a new genus and species by Clench (1957), based on 21 specimens from central Bolivia (Prov. del Sara; Buena Vista and Rio Japacani). He indicated that Givarbela (Figs 1‒8) belongs to the Langsdorfia-Givira group of genera but differs from them by the following combination of characters: "R2 stalked with R3-R4, R5 free; the long palpi; absence of fore tibial epiphysis; absence of median cell-vein on fore wing and the open cell-end there; stalked M2-M3 on hind wing; absence of all but traces of a single hind wing anal vein; short hind wing cell; deeply excised hind wing costa" (Clench 1957).

Taxonomic notes on the genera Brypoctia Schoorl, 1990 and Schreiteriana Fletcher & Nye, 1982 (Lepidoptera, Cossidae).

Currently, the Cossidae of South America are rather poorly studied. Data on the distribution and taxonomy of Neotropical carpenter moths are lacking. An exception is the clarification of the taxonomic position of the genus Miacora Dyar, 1905 (Yakovlev 2014), Neotropical Cossidae checklist (Donahue 1995), and a preliminary list of Cossidae  of Argentina (Penco & Yakovlev 2015). The majority of Neotropical Cossidae genera have not been studied and the taxonomic position of some genera remains completely unresolved. Additionally, images of genitalia of the Neotropical genera have not been published, including the genera Brypoctia Schoorl, 1990 and Schreiteriana Fletcher & Nye, 1982 (Cossidae: Zeuzerinae). The taxonomic position of the second genus was questioned by Schoorl (1990).
