Insect visitors to extrafloral nectaries of Byttneria aculeata (Sterculiaceae): relative importance and roles

Abstract. 1. Ants, parasitoids and flies are about equally frequent at foliar nectaries of Byttneria aculeata (Sterculiaceae) in lowland Costa Rica during the dry season, a pattern previously unreported but also observed at other plants in the area.

Dispersion and the size composition of the aerial insect fauna

Abstract. 1. Beetles sampled in Louisiana at higher levels in the atmosphere were significantly smaller than those sampled at lower levels, which suggests that passive buoyancy is important in high altitude dispersal.

New Lechriops Species for the United States (Coleoptera: Curculionidae: Conoderinae)

Abstract Two new species of Lechriops are described from Arizona: L. variegatus n. sp. and L. chiricahuae n. sp. Lechriops oblongulus Champion, previously described from Durango, México, is recorded for the first time from Arizona and is redescribed. These three species and L. californicus (LeConte) are associated with pines and Douglas fir and constitute the californicus group. A revision of Sleepers (1963) key is given to separate the species of Lechriops in the United States and male genitalia are illustrated for the four species and for L. oculatus (Say). Other undescribed species in the californicus group are known from México to Honduras.

A New Eulechriops for the United States (Coleoptera: Curculionidae: CONODERINAE)

Abstract Eulechriops elongatus Champion, previously described from Morelos, México, is reported from Arizona for the first time. The species is redescribed and distinguished from the eastern North American species E. minutus (LeConte), genitalia are figured, and new distribution data are given for both species. Members of the minutus group appear to be associated with oaks and additional undescribed species are known from México. One or two specimens each of at least two and possibly three apparently undescribed Eulechriops species are known from Arizona and Texas.

A new Eulechriops (Coleoptera: Curculionidae, Conoderinae) from Brazil attacking Rubus

Two New Weevils (Coleoptera: Curculionidae: Conoderinae) from Cocos Island, Costa Rica

Abstract Two species in the weevil subfamily Conoderinae are described from Cocos Island, Costa Rica. The more common Hoplocopturus sherrywernerorum, new species, is sexually dimorphic and has a Lechriops-like pattern of setae similar to the Central American H. ochreicollis Champion, although it does not seem closely related to any mainland species. Copturomimus hoguei, new species, is a larger species with elytral costae similar to the widespread Central American C. octocostatus Champion.

A New Eulechriops from Arizona and México (Coleoptera: Curculionidae: Conoderinae) with Distributional Notes for Other Species in the Genus

Abstract Eulechriops hovorei, new species, is described from Arizona and Guerrero, México and named in honor of the late Frank Hovore. Eulechriops leucospilus Champion is reported for the first time from México and E. elongatus Champion for the first time from California.

A Reconsideration of Hylaeogena Obenberger, 1923 (Coleoptera: Buprestidae), with Descriptions of a New Genus and New Species from Mexico and Central America

Abstract The leafmining genus Hylaeogena Obenberger, 1923, as currently recognized, is considered to consist of two subgenera, Hylaeogena s. str. and Hedwigiella Obenberger, 1941. Examination of types detected substantial, consistent differences among three different sets of species. I propose that Hylaeogena be split into three genera: Hylaeogena, Hedwigiella, new status, and Euhylaeogena Hespenheide, new genus, with Euhylaeogena byattae Hespenheide, new species, as the type species of Euhylaeogena. Surprisingly, most species belong to the undescribed genus, and only three species are recognized in each of Hylaeogena and Hedwigiella, with Hylaeogena bellamyi Hespenheide, new species, Hedwigiella cbellamyi Hespenheide, new species, and Euhylaeogena clbellamyi Hespenheide, new species, described as new. Hedwigiella laticeps (Waterhouse, 1889) is treated as a new combination. The following species are included in Euhylaeogena: Euhylaeogena affinis (Obenberger, 1923), new combination, Euhylaeogena alibertiae (Fisher, 1930), new combination, Euhylaeogena astraea (Waterhouse, 1889), new combination, Euhylaeogena atroviridis (Fisher, 1922), new combination, Euhylaeogena centralis (Waterhouse, 1889), new combination, Euhylaeogena cincta (Waterhouse, 1889), new combination, Euhylaeogena coelicolor (Obenberger, 1925), new combination, Euhylaeogena compacta (Waterhouse, 1889), new combination, Euhylaeogena constans (Waterhouse, 1889), new combination, Euhylaeogena discoidalis (Waterhouse, 1889), new combination, Euhylaeogena festiva (Fisher, 1922), new combination, Euhylaeogena gratiosula (Obenberger, 1925), new combination, Euhylaeogena grouvellei (Théry, 1934), new combination, Euhylaeogena hydroporoides (Waterhouse, 1889), new combination, Euhylaeogena kirschi (Obenberger, 1925), new combination, Euhylaeogena lecerfi (Obenberger, 1932), new combination, Euhylaeogena modesta (Waterhouse, 1889), new combination, Euhylaeogena ovalis (Waterhouse, 1889), new combination, Euhylaeogena pilosa (Fisher, 1922), new combination, Euhylaeogena rotundipennis (Fisher, 1922), new combination, and Euhylaeogena thoracica (Waterhouse, 1889), new combination.

A Reconsideration of Pachyschelus schwarzi Kerremans and a Review of American Pachyschelus North of MÉxico (Coleoptera: Buprestidae)

Abstract The Pachyschelus fauna of America north of México is comprised of eight species plus one additional subspecies. Three species were found in collections under the name of P. schwarzi Kerremans. P. vogti new species from South Carolina, Georgia, and Florida is described and figured as new. P. nicolayi Obenberger, originally described as a variety of P. schwarzi Kerremans, is considered to be a full species and distinguished from P. schwarzi; both are redescribed and figured. A key is given to separate species and full synonymies and hosts are given for each species. Brachys carbonata LeConte, heretofore considered a synonym of P. laevigatus (Say), is transferred to the genus Leiopleura as L. carbonata (LeConte) new combination.

A Striking New Species of Macrocopturus Heller, 1895 (Coleoptera: Curculionidae: Conoderinae) from Panama: Raising the Question of Coloration

Abstract Macrocopturus richardpackeri Hespenheide, new species, is described from Panama and named in honor of Richard Roland Edward Packer. The possibility of mimicry and the necessity for an adaptive explanation are discussed for this and a complex of red-spotted species in several conoderine genera.
