Germarostes (Haroldostes) rugiceps (Germar) and Germarostes (Haroldostes) diffundus (Petrovitz) (Ceratocanthinae) are recorded for the first time for Argentina from Misiones and Corrientes, respectively. This brings to thirteen the total number of the Ceratocanthinae species recorded for Argentina up to now. Some remarks on the type series of G. diffundus and on the collecting circumstances of ...

Abstract Phytophagous scarab beetles associated with angiosperms have characteristically enlarged lamellate antennae and exhibit a striking morphological variation of sensilla. In this study, we compared the morphology antennal surface 62 species Scarabaeoidea using SEM microscopy, particularly also in light their evolution association angiosperms. We investigated correlation sensilla morpholog...

Martínez NJ, Franz NM, Acosta JA. 2009. Structure of the scarab beetle fauna (Coleoptera: Scarabaeoidea) in forest remnants of western Puerto Rico. Entomotropica 24(1): 1-9. We studied the richness and abundance of scarab beetle species (Coleoptera: Scarabaeoidea) in two successional forest fragments located on the campus of the University of Puerto Rico at Mayagüez (UPRM), western Puerto Rico....

Various types of weapon traits found in insect order Coleoptera are known as outstanding examples of sexually selected exaggerated characters. It is known that the sex determination gene doublesex (dsx) plays a significant role in sex-specific expression of weapon traits in various beetles belonging to the superfamily Scarabaeoidea. Although sex-specific weapon traits have evolved independently...

Considering the turmoil and vast changes in the classification of the superfamily Scarabaeoidea during the last 20 years, particularly in North America, we were asked to provide an update for the readers of Scarabs wherein we offer our perspectives. Much of what follows is extracted from our scarabaeoid introduction in American Beetles (Jameson and Ratcliffe 2002). By the time this overview is ...

Dung beetles belong to the superfamily Scarabaeoidea, and are mostly within the subfamilies of Scarabaeinae and Aphodiinae. They are given their name because they feed partially or exclusively on feces. Each species of dung beetles can be classified as one of several types: rollers, tunnelers and dwellers. Rollers roll the dung into round balls, which are then used for brooding chambers or as a...

the present study was conducted to assess the effect of dung beetles on sheep dung removal and seed dispersal in semi steppe rangelands of shahrekord province with poor condition located in iran. therefore, the large (1 cm2) and small size (1 mm2) meshes were used and filled by sheep dung in six treatments. to evaluate the role of the insects in seeds translocation, three sizes of plastic beads...

An updated checklist of the Lucanidae (Coleoptera) from Iran is given. New locality records are listed and some dubious distributional records are discussed. Dorcus vavrai Nonfried, 1905 is placed in synonymy with Dorcus peyronis Reiche and Saulcy, 1856 (new synonymy) The female of Lucanus xerxes Král, 2004 is described. A key for the identification of the Iranian stag beetle species is also pr...

The Australian fauna of Ceratocanthinae (Coleoptera, Scarabaeoidea, Hybosoridae) is revised. Two genera are present, both shared with Asia, with a total of seven species, all localized in eastern Queensland and all except one, endemic to Australia. Cyphopisthes is comprised of three species, two of them new (Cyphopisthes yorkensis sp. n. and Cyphopisthes monteithi sp. n., the latter, together w...
