North American snout moths pinned with their wings spread out flat for study. Credit: Dr. Alma Solis The present snout moth list contains a ten-percent increase in the number of species since 1983. For the last thirty-three years snout moth specialists in the United States and Canada have been describing species new to science and recording species new to these two countries. Scientists have also published studies resulting in major changes to the classification above the species level, for example by studying snout moth "ears" (tympanal organs) and utilizing genes to study their relationships. This check list was compiled over a three-year period by Dr. Brian Scholtens and Dr. M. Alma Solis. Brian Scholtens is a professor at the College of Charleston, South Carolina, and M. Alma Solis is a research entomologist at the Agriculture Research Service's Systematic Entomology Laboratory, and curator of the U.S. National Pyraloidea Collection located at the Smithsonian Institution, National Museum of Natural History, Washington, D.C. Their results have been published in the open-access journal ZooKeys. "A check list is one of the most important pieces of research, with many applications," says Dr. Solis. "Knowing the fauna of a geographic area makes it possible to track species and, in this case, potential invasive species. The caterpillars of snout moths are economically important worldwide as pests of planted crops for food or biofuel, of forest trees, and of stored products such as wheat and nuts." "Many species, for example, the stored product pests, occur worldwide, but others, such as pest species of grasses including corn, can be restricted or only exist in certain geographic areas," the scientist further explains. "It is important to be able to recognize as soon as possible that a particular species is not native to the United States or Canada." Scientists use Latin scientific names as "unique tags" to communicate about the morphological or molecular identity and habits of a species. One of the functions of taxonomists is to determine if a species is new or if it has already been described. Historically, confusion is created when the same species is described more than once (called a synonym) in other parts of the world. A regional check list such as this one and a worldwide check list can work together to reinforce precision in the definition and communication about species, especially decreasing confusion about synonyms. Most worldwide check lists exist as online databases that can be updated. Dr. Solis said that they had cited new discoveries relevant to the North American snout moth fauna found in GLOBIZ, or the Global Information System on Pyraloidea, an electronic list of over 15,500 snout moth species names for which she is a collaborator.

Rhoptobaris LeConte (= Orthoris LeConte, new synonymy), a small genus of North and Central American weevils, is revised. The adult, larva, and pupa are described. Five species are recognized: Rhoptobaris canescens LeConte, Rhoptobaris cylindrifera (Casey), new combination [from Orthoris], Rhoptobaris obrieni Prena, new species [El Salvador, Honduras, Mexico], Rhoptobaris piercei Prena, new species [Mexico, USA], and Rhoptobaris scolopax (Say), new combination [from Aulobaris LeConte]. At least three species are associated with blazingstar (Mentzelia L., Loasaceae). Orthoris angustula Casey, Orthoris captiosa Casey, Orthoris crotchii LeConte, Orthoris robustula Casey, Orthoris tenuirostris Casey, and Orthoris tumidirostris Casey are new synonyms of R. scolopax. Lectotypes are designated for R. canescens, O. crotchii, O. captiosa, Orthoris cylindrifera Casey, and O. tenuirostris. Baridius anthracinus Boheman is designated as the type species for Aulobaris LeConte. Aulobaris pusilla (LeConte) is recognized as the valid name for B. scolopax of authors (not Say 1832). Habitus images of all five species, line drawings of important larval characters, and a key for the identification of the adult weevil are provided.

A total of 12,540 ripe fruits belonging to 46 species in 25 plant families were sampled from either the trees or the ground in 6 municipalities in the state of Santa Catarina, Brazil between 2002 and 2006 to determine which fruit fly species developed on various host plants. Each fruit was weighed and placed into a plastic flask filled with sterilized sand 7 cm deep, and the opening of the flask was covered with sheer fabric. The flasks were kept under controlled conditions (25 ± 3°C, 70 ± 10% RH and 12h photophase). After 7 d, the pupae were sifted from the sand and transferred to Petri dishes lined with filter paper. Twenty-one species of Tephritoidea were recovered consisting of 13 species of Tephritidae, 6 of Lonchaeidae, and 2 of Ulidiidae. We present new host records for some species of fruit flies.

Lipancylus copelatus Prena, new species, is described from Arizona and Texas (type locality Davis Mountains Resort, TX) and Lipancylus cracens Prena, new species, from Texas and Mexico (type locality Bentsen-Rio Grande Valley State Park, TX). They have been confused in the past with Lipancylus parallelus (Champion) (formerly Strongylotes Schönherr), a species present in Mexico and Honduras but not in the United States. Collecting records of L. copelatus and several undescribed species indicate that the larval development takes place in grasses.

Taiwanese species of Mandarella Duvivier are compared on the basis of morphological and molecular evidence. Only three of eleven morphospecies are considered to be valid. Mandarella uenoi (Kimoto, 1969) is transferred from the genus Luperus Geoffroy. Stenoluperus taiwanus Kimoto, 1991 and Stenoluperus kimotoi Dberl, 2001 are synonymized with Mandarella uenoi. Taiwanese records of Stenoluperus tibialis Chen, 1942, Stenoluperus nipponensis Laboissire, 1913, and Stenoluperus potanini (Weise, 1889) were based on misidentifications and represent Mandarella uenoi. The Taiwanese population previously erroneously identified as Stenoluperus pallipes Gressitt and Kimoto, 1963 is here described as a new species, Mandarella tsoui sp. n., Stenoluperus esakii Kimoto, 1969, Stenoluperus matsumurai Takizawa, 1978, and Mandarella taiwanensis Medvedev, 2012 are synonymized with Mandarella flaviventris (Chen, 1942).
