A review of the genus Megalographa Lafontaine and Poole (Lepidoptera: Noctuidae: Plusiinae) with the description of a new species from Costa Rica

The classification of the genus Megalographa Lafontaine and Poole, 1991, is reviewed and the five known species diagnosed. The genus is essentially restricted to the New World, although one species M. biloba (Stephens) is migratory and has occasionally straggled to western Europe. A new species (Megalographa talamanca Lafontaine and Sullivan) endemic to the Talamanca Mountain Range in Costa Rica is described. Adults and genitalia are illustrated

New species of the Neotropical genus Campatonema Jones (Geometridae, Ennominae) with the first description of the female

Two new species of Campatonema Jones are described, C. tapantia sp. n. from Costa Rica and C. yanayacua sp. n. from Ecuador. A third species, Campatonema lineata (Schaus), is transferred to Campatonema from “Sabulodes.” The female of Campatonema is described for the first time, and the tribal placement of Campatonema is discussed

The Phyllodonta latrata (Guenée) species group in Costa Rica (Geometridae, Ennominae)

Historically, the name Phyllodonta latrata (Guenée) has been applied to what is a complex of three undescribed species in Costa Rica. They are very similar in maculation, but can be differentiated by genitalic characters and barcodes. P. alajuela Sullivan, sp. n. occurs at lower altitudes in the northwestern part of Costa Rica whereas P. intermediata Sullivan, sp. n. and P. esperanza Sullivan, sp. n. are found at partially overlapping altitudes in the central mountain ranges

A New Species of Rivula Guenée (Lepidoptera, Noctuidae) from Southeastern United States

Rivula stepheni sp. n. (Noctuidae, Rivulinae) is described from material collected in North Carolina and Louisiana. Illustrations of genitalia and adults of Rivula found in the United States are provided. The generic placement within the Noctuoidea is discussed

Two new species of the Hagnagora anicata complex (Geometridae, Larentiinae) from Costa Rica

Examination of the lectotype (here designated) reveals that Hagnagora anicata (Felder & Rogenhofer) does not occur in Costa Rica. Instead two new species are described, H. elianne sp. n. and H. unnia sp. n., and their distribution is discussed. The previous treatment of H. anicata as a single widespread species ranging from Jamaica and Mexico to Bolivia needs to be critically evaluated

A revision of the genus Doryodes Guenée, 1857, with descriptions of six new species (Lepidoptera, Erebidae, Catocalinae, Euclidiini)

The genus Doryodes Guenée is revised to include ten species including six species described as new (D. desoto Lafontaine & Sullivan; D. okaloosa Sullivan & Lafontaine; D. fusselli Sullivan & Lafontaine; D. reineckei Sullivan & Lafontaine; D. broui Lafontaine & Sullivan; and D. latistriga Sullivan & Lafontaine). A key to species, descriptions, and illustrations of adults and genitalia are included

The Disphragis notabilis (Schaus) species-group in Costa Rica (Lepidoptera, Notodontidae)

The four described taxa in the Disphragis notabilis (Schaus) species-group are reviewed, including the types and their dissected genitalia. Disphragis hemicera (Schaus), stat. rev., is elevated to species rank, D. normula (Dognin) is retained as a synonym of D. notabilis, D. sobolis Miller is confirmed as distinct from D. hemicera, and D. bifurcata sp. n., is newly described. Both D. hemicera and D. bifurcata occur in Costa Rica. The known ranges of the other species are outlined. Defining characters of each species are presented and a key to species is provided. Unusual variation in the genitalia is noted
