‘Retournement’ of the aedeagus in Curculionidae (Coleoptera, Curculionoidea)
Krishna Kumar Verma
- Retournement or turning of the aedeagus about its longitudinal axis through about 180o during development is known in Chrysomeloidea (Coleoptera). This change in the orientation of the organ may be observed during the postembryonic development. This change produces certain morphological effects. By observing these morphological features in the imago the retournement may be inferred. Such morphological features in Curculionidae (Coleoptera) are here recorded. From this it has been inferred not only that retournement of the aedeagus is included in the ontogeny of curculionids, but also that the change of orientation of the organ occurs by the same mechanism as in Chrysomeloidea. These inferences attest the notion of a close phyletic relationship between the superfamilies Curculionoidea and Chrysomeloidea.
Xyloryctes Hope, 1837 (Coleoptera: Scarabaeidae: Dynastinae: Oryctini) in the United States. Qui es et ubi fuisti et quo vadis?
Brett C. Ratcliffe
- Two species of Xyloryctes occur in the United States: X. jamaicensis (Drury) and X. thestalus Bates. Identification and distribution of these species has long been confused but is reviewed and clarified here. Xyloryctes jamaicensis occurs only in the eastern half of the U.S. and not in the southwestern U.S. as previously thought, while X. thestalus occurs in Guatemala and southern Mexico northwards to the southwestern United States. This hypothesis is corroborated by biogeographical and host plant data. Three new synonyms are listed for X. thestalus: X. faunus Casey 1915, X. hebes Casey 1915, and X. thestalus borealis Endrödi. The decline of Fraxinus spp., the food plant of Xyloryctes species, as a result of damage caused by the introduced emerald ash borer (Agrilus planipennis Fairmaire; Buprestidae) in the United States might portend a similar decline for Xyloryctes species in North America.
World Checklist of Tribe Calpini (Lepidoptera: Noctuidae: Calpinae)
Jennifer M. Zaspel
Marc A. Branham
- A preliminary checklist of Calpini is provided, incorporating corrections and changes to publication dates and nomenclature as presented in the checklists of Poole (1989), Fibiger and Lafontaine (2005), and Holloway (2005). Culasta Moore is removed from synonymy with Calyptra Ochsenheimer. Eudocima talboti (Prout) and Graphigona antica Walker are placed in synonymy with E. cajeta (Cramer) and G. regina (Guenée), respectively. Africalpe Krüger, Ferenta Walker, Gonodonta Hübner, Graphigona Walker, Oraesia Guenée, and Tetrisia Walker, are added to the tribe based on shared characters. The genera Cecharismena Möschler, Goniapteryx Perty, Pharga Walker, Phyprosopus Grote, Psammathodoxa Dyar, and Radara Walker are removed and considered incertae sedis. Hemiceratoides and Phyllodes are not considered to be members of Calpini.
World Catalogue of Propalticidae, with a replacement name for Discogenia Kolbe (Coleoptera: Cucujoidea)
Matthew L. Gimmel
- An annotated world catalogue and bibliography of the cucujoid family Propalticidae (Coleoptera) is presented. Each taxon is accompanied by a complete taxonomic history, including a full annotated synonymy with original references cited, and current location and status of primary types. The name Slipinskogenia nom. nov. is proposed to replace Discogenia Kolbe, 1897, junior homonym of Discogenia LeConte, 1866, resulting in 11 new combinations. A key is provided for separation of the two genera included in the family. Complete published and previously unpublished distributional data are given.
Weevils of the genus Cercopeus Schoenherr from South Carolina, USA (Coleoptera: Curculionidae: Entiminae)
Charles William O'Brien
Janet C. Ciegler
Jennifer C. Girón
- Six new species of the weevil genus Cercopeus Schoenherr are described from South Carolina: C. alexi, C. cornelli, C. femoratus, C. paulus, C. skelleyi, and C. tibialis. Three other species also found in South Carolina are redescribed: C. chrysorrhoeus (Say), C. maspavancus Sleeper, and C. strigicollis Sleeper. Keys to known males and females of all 17 species of Cercopeus are given, along with photographs of habitus, leg features, and antennae, and line illustrations of genitalia. Nearly all specimens of the new species were collected from January-March and these species are winter active.
Vespidae (Insecta: Hymenoptera) of Puerto Rico, West Indies
James M. Carpenter
Julio A. Genaro
- The vespid fauna of Greater Puerto Rico is reviewed (Hymenoptera: Vespidae). Three new species are
described, Ancistrocerus isla Carpenter, Euodynerus jeitita Carpenter and Genaro, and Omicron aridum Carpenter
and Genaro. Polistes crinitus americanus (Fabricius, 1775) and P. crinitus multicolor (Olivier, 1792) are both
reduced to synonyms of nominotypical P. crinitus (Felton, 1765), revised status; Zeta abdominale hispaniolae
(Bequaert and Salt, 1931) and Zeta abdominale ornatum (de Saussure, 1855) are both reduced to synonyms of
nominotypical Zeta abdominale (Drury, 1770), revised status; and Zethus rufinodus monensis Bohart and Stange,
1965, and Zethus rufinodus virginicus Bohart and Stange, 1965, are both reduced to synonyms of nominotypical
Zethus rufinodus (Latreille, 1806), revised status. Parancistrocerus obliquus (Cresson, 1865) is newly recorded
from Puerto Rico. The presence of Pachodynerus guadulpensis (de Saussure, 1853) in Puerto Rico is confirmed. An
analysis of the composition of the Puerto Rican vespid fauna is presented.
Two species of Compsus Schoenherr, new citrus pests from Colombia (Coleoptera: Curculionidae: Entiminae)
Charles W. O’Brien
- Two species of the weevil genus Compsus Schoenherr (Coleoptera: Curculionidae: Entiminae) from
Colombia are redescribed: C. obliquatus Hustache and C.viridivittatus (Guérin-Méneville). A key by Hustache
in 1938, to 33 of the 34 recognized species of Colombian Compsus then known, is modified to include the one additional
species. Habitus illustrations of males and females of the two species and illustrations of selected parts
of the male and female genitalia are included. Nearly all of the specimens of these two species were collected on
various species or varieties of citrus, indicating their potential as citrus pests in the future.
Two new species of the genus Pahamunaya Schmid (Trichoptera: Polycentropodidae) from Vietnam
Tatiana I. Arefina-Armitage
Brian J. Armitage
- Two new species of the genus Pahamunaya Schmid (Trichoptera: Polycentropodidae), P. talon sp. n. and P. spinifera sp. n., from Vietnam are described and illustrated. Examination of the holotype male of P. khoii Oláh and Johanson, in combination with an additional specimen of the same species, revealed new characters. New illustrations for this species are provided.
