Corrections To Neotropical Rhinaspis Perty And Plectris Lepeletier And Audinet-Serville (Coleoptera: Scarabaeidae: Melolonthinae) Classifi Cation And Nomenclature, Andrew B. T. Smith Jan 2016

Corrections To Neotropical Rhinaspis Perty And Plectris Lepeletier And Audinet-Serville (Coleoptera: Scarabaeidae: Melolonthinae) Classifi Cation And Nomenclature, Andrew B. T. Smith

Insecta Mundi

The name Melolontha hypocrita Mannerheim, 1829 has been long unused, even though it is the type species of Hyporhiza Dejean, 1833. I examined the only known specimen from the type series and here designate it as the lectotype. Examination of this lectotype reveals that this species is best placed in the genus Rhinaspis Perty, 1830. Consequently, the genus Hyporhiza Dejean, 1833 is confi rmed as a junior synonym of Rhinaspis. Further, the replacement name Rhinaspis fuhrmanni is proposed for Rhinaspis hypocrita (Blanchard, 1850), a new secondary homonym of Rhinaspis hypocrita (Mannerheim, 1829). A homonymy problem was also discovered and …

New Antlion Records (Neuroptera: Myrmeleontidae) From Paraguay, Olga Petko, Paul Smith, Lionel Stange, Sergio D. Rios

Insecta Mundi

New records of Myrmeleontidae from Paraguay are presented: Dimares elegans (Perty, 1833), Glenurus croesus Banks, 1922, Glenurus penningtoni (Navás, 1918a) and Vella fallax (Rambur, 1842).

Enoclerus Gahan: Predators Of Chemically Protected Ladybird Beetles (Coleoptera: Cleridae And Coccinellidae), Jacques Rifkind Jan 2016

Enoclerus Gahan: Predators Of Chemically Protected Ladybird Beetles (Coleoptera: Cleridae And Coccinellidae), Jacques Rifkind

Insecta Mundi

Four species of the genus Enoclerus (Coleoptera: Cleridae) are reported to prey on chemically protected Coccinellidae in North America. The possibility that aposematically colored Enoclerus also mimic prey ladybird species is discussed, and the further possibility that clerid predators acquire chemical protection through sequestration of ladybird prey’s toxic alkaloids is suggested as an important avenue of investigation. The data presented are primarily based on photographs taken by non-specialists, discovered through Internet search. The crowdsourcing of natural history observations can reveal aspects of animal behavior heretofore unreported and even unsuspected.

Recent shifts in US policies towards Cuba suggest a relaxation or lifting of the embargo may occur in the

near future. With the prospects of open travel and trade with Cuba come concerns over the introduction of agricultural

pests. In an effort to assess these concerns the distribution-based introduction risk of pests listed in the 2015 Cooperative

Agricultural Pest Survey’s (CAPS) list of priority pests of economic and environmental importance is reviewed. Of

the 59 pests on the CAPS priority pest list, 20 have been recorded in the literature as being present in the Caribbean

Basin, South America and Central …

Absence Of Mate Choice And Postcopulatory Benefits In A Species With Extreme Sexual Size Dimorphism, Marie-Claire Chelini, Eileen A. Hebets Jan 2016

Absence Of Mate Choice And Postcopulatory Benefits In A Species With Extreme Sexual Size Dimorphism, Marie-Claire Chelini, Eileen A. Hebets

Eileen Hebets Publications

Most hypotheses related to the evolution of female-biased extreme sexual size dimorphism (SSD) attribute the differences in the size of each sex to selection for reproduction, either through selection for increased female fecundity or selection for male increased mobility and faster development. Very few studies, however, have tested for direct fitness benefits associated with the latter – small male size. Mecaphesa celer is a crab spider with extreme SSD, whose males are less than half the size of females and often weigh 10 times less. Here, we test the hypotheses that larger size in females and smaller size in males …
