Larissimusnigricans sp. nov. (Hymenoptera, Braconidae), a new reared species of a rare neotropical genus recovered through biodiversity inventory in Ecuador.

A new species of the rarely collected neotropical microgastrine braconid wasp genus Larissimus Nixon, represented previously by only a single described species, L.cassander Nixon, was recovered by the Caterpillars and Parasitoids of the Eastern Andes in Ecuador inventory project. Larissimusnigricanssp. nov. was reared from an unidentified species of arctiine Erebidae feeding on the common bamboo species Chusqueascandens Kunth at the Yanayacu Biological Station near Cosanga, Napo Province, Ecuador. The new species is described and diagnosed from L.cassander using both morphological and DNA barcode data.

A new species of Trismegistomya Reinhard (Diptera: Tachinidae) from Area de Conservación Guanacaste in northwestern Costa Rica.

BACKGROUND: The New World genus Trismegistomya Reinhard, 1967b (Diptera: Tachinidae) previously included only the type species Trismegistomya pumilis (Reinhard, 1967a) from Arizona, U.S.A. NEW INFORMATION: We describe a new species of Trismegistomya, Trismegistomya jimoharai Fleming & Wood sp. n., from Area de Conservación Guanacaste (ACG) in northwestern Costa Rica, reared from wild-caught caterpillars of Melipotis januaris (Guenée, 1852) (Lepidoptera: Erebidae). Our study provides a concise description of the new species using morphology, life history, molecular data and photographic documentation. In addition to the new species description, we provide a redescription of the genus, as well as of its type species Trismegistomya pumilis.

Additions and corrections to the check list of the Noctuoidea (Insecta, Lepidoptera) of North America north of Mexico IV.

A summary of all taxonomic and nomenclatural changes to the check list of the Noctuoidea of North America north of Mexico since the last update published in 2015 is provided. A total of 64 changes are listed and discussed, consisting of 26 recently published changes and additions, and an additional 38 presented herein. One stat. n., one stat. rev., six syn. n., and two comb. n. are proposed for the first time. Orthimella Schmidt & Lafontaine nom. n. is proposed here as an objective replacement name for Himella Grote, 1874 [Noctuinae: Orthosiini], a junior homonym of Himella Dallas, 1852 [Hemiptera: Coreidae].

Diolcogaster flammeus sp. nov. from Brazil, a new Microgastrinae wasp (Hymenoptera: Braconidae) of importance in biological control

ABSTRACT A new species of Diolcogaster (Ashmead, 1900) (Hymenoptera: Braconidae) is described and illustrated. Additionally, a key to all New World species formally published of the xanthaspis species-group (to which the new species belongs) is provided. The solitary larval parasitoid Diolcogaster flammeus sp. nov. was collected in Viçosa, Minas Gerais State, Brazil. This natural enemy was reared from caterpillars of Agaraea minuta (Schaus, 1892) (Lepidoptera: Erebidae) feeding on plants of spiked spiralflag ginger, Costus spicatus (Jacq.) Sw. and ginger spiral, Costus spiralis (Jacq.) Roscoe var. spiralis (Costaceae). The fauna of the xanthaspis group in the New World included just three published species prior to this publication. Diolcogaster flammeus sp. nov. is the only yellow-orange species of the xanthaspis group recorded in the New World thus far.

A new species of Phosocephala Townsend, 1908 (Diptera: Tachinidae) from Area de Conservación Guanacaste in northwestern Costa Rica.

BACKGROUND: We describe a new species of Phosocephala Townsend, and provide a new collection record, and description of the previously unknown male, of Phosocephala metallica Townsend, from Area de Conservación Guanacaste (ACG), northwestern Costa Rica. All ACG specimens were reared from wild-caught Lepidoptera larvae (Lepidoptera: Erebidae, Nolidae). We provide a concise description of both species using morphology, life history, molecular data, and photographic documentation. The new species is authored and described by Fleming and Wood. NEW INFORMATION: Phosocephala alexanderi sp. n.

Additions and corrections to the check list of the Noctuoidea (Insecta, Lepidoptera) of North America north of Mexico III.

A total of 124 additions and corrections are listed and discussed for the check list of the Noctuoidea of North America north of Mexico published in 2010. Twenty-eight species are added to the list, 16 through new species descriptions, eight as a result of taxonomic splits, and four based on newly recorded species. Forty-eight species are deleted from the list, 41 through synonymy, and seven that were based on misidentifications. Twelve changes are corrections in the spelling of names, or changes in parentheses on dates of publication. Twenty-seven are changes in taxonomy of names where no species are added or deleted; eight changes involve the renumbering of existing species for better taxonomic arrangement. Within the text 2 stat. n., 10 stat. rev., 27 syn. n., 5 syn. rev., and 1 comb. n. are proposed for the first time.

The type-material of Arctiinae (Lepidoptera, Erebidae) described by Burmeister and Berg in the collection of the Museo Argentino de Ciencias Naturales Bernardino Rivadavia (Buenos Aires, Argentina).

Carlos G. Burmeister and Carlos Berg were among the most important and influential naturalists and zoologists in Argentina and South America and described 241 species and 34 genera of Lepidoptera. The Museo Argentino de Ciencias Naturales Bernardino Rivadavia (MACN) housed some of the Lepidoptera type specimens of these authors. In this study we present a catalogue with complete information and photographs of 11 Burmeister type specimens and 10 Berg type specimens of Phaegopterina, Arctiina and Pericopina (Lepidoptera, Erebidae, Arctiinae, Arctiini) housed in the MACN. Lectotypes or holotypes were designated where primary type specimens could be recognized; in some cases we were not able to recognize types. The catalogue also proposes nomenclatural changes and new synonymies: Opharus picturata (Burmeister, 1878), comb. n.; Opharus brunnea Gaede, 1923: 7, syn. n.; Hypocrisias jonesi (Schaus, 1894), syn. n.; Leucanopsis infucata (Berg, 1882), stat. rev.; Paracles argentina (Berg, 1877), sp. rev.; Paracles uruguayensis (Berg, 1886), sp. rev.
