The Ochodaeidae of Argentina (Coleoptera, Scarabaeoidea)  [cached]
M.J. Paulsen,Federico Ocampo
ZooKeys , 2012, DOI: 10.3897/zookeys.174.2668
Abstract: The Ochodaeidae (Coleoptera: Scarabaeoidea) of Argentina are revised. Previously, two species of Ochodaeinae were known from the country, both in the genus Parochodaeus Nikolajev: P. campsognathus (Arrow) and P. cornutus (Ohaus). An additional 7 species of Parochodaeus from Argentina are described here as new. In addition, Gauchodaeus patagonicus, new genus and new species in the subfamily Chaetocanthinae, is described. This is the first record of the subfamily Chaetocanthinae in South America. Redescriptions, diagnoses, and maps are provided for each species. We also provide a key to genera and a key to species of Parochodaeus of Argentina. With this work, the number of ochodaeid species known from Argentina is increased from 2 to 10.

Abstract: Not available Este artículo, elaborado en 1999, ofrece una panorámica de la realidad del Consejo Superior de Investigaciones Científicas en la actualidad. Repasa su organización, su volumen de publicaciones, sus indicadores de productividad, su capacidad de obtener recursos y, en suma, su lugar en el conjunto del sistema espa ol de Ciencia y Tecnología, considerado en sí mismo y en relación con la Universidad. Como conclusión del repaso de datos, se afirma que, aunque la fórmula del CSIC, como organismo nacional e interdisciplinario, no es la única posible, la organización del Estado de las Autonomías, así como la evaluación de los datos con que se cuenta, la hacen vivamente recomendable. No hay, pues, sino que seguir con su desarrollo.

A new genus and species of Ceratocanthidae from Tanzania (Coleoptera: Scarabaeoidea)  [cached]
Alberto Ballerio
African Zoology , 2011,
Abstract: Cryptophilharmostes mahunkain.gen., n.sp., a remarkable Ceratocanthidae (Coleoptera: Scarabaeoidea) from the Usambara Mountains(Tanzania), is described. The morphology of the clypeus and mesoepisternum is discussed, also with reference to other Ceratocanthidae. The affinities of the genus are discussed, and within the Afrotropical fauna a group of genera formed by Philharmostes Kolbe and its allies is recognized.
Characterization of 7H Nuclear System  [PDF]

Abstract: The 7H resonance was produced via one-proton transfer reaction with a 8He beam at 15.4A MeV and a 12C gas target. The experimental setup was based on the active-target MAYA which allowed a complete reconstruction of the reaction kinematics. The characterization of the identified 7H events resulted in a resonance energy of 0.57(+0.42-0.21) MeV above the 3H+4n threshold and a resonance width of 0.09(+0.94-0.06) MeV.
Evolución biogeográfica de los Pachydeminae paleárticos (Coleoptera, Scarabaeoidea) mediante análisis de dispersión-vicarianza  [cached]
Sanmartín, Isabel
Graellsia , 2003,
Abstract: The beetle subfamily Pachydeminae Reitter, 1902 is one of the least-known subfamilies of Melolonthidae or “leaf-chafers” (Coleoptera, Scarabaeoidea). Some species of Pachydeminae have recently been described as agricultural pests of olive trees. The Pachydeminae are distributed in all major zoogeographical regions (except Australia and India) but their distribution is very disjunct. In the Palearctic region, they are distributed across southern Eurasia from the Canary Islands to China, including southern Europe (except France and Italy), North Africa, Asia Minor, Middle East, Iran-Afghanistan, Caucasus, and Central Asia. The majority of species occur in the southwestern Palearctic, with only a few species in China. As in the rest of Melolonthidae subfamilies (Browne & Scholtz, 1999), phylogenetic relationships within the Pachydeminae are poorly resolved. Recently, Sanmartín & Martín-Piera, (2003) reviewed the systematics of the Palearctic genera, and proposed the first phylogenetic hypothesis within the subfamily. This study summarizes the conclusions of Sanmartín (1998) and Sanmartín (2003), which reconstructed the biogeographic history of the subfamily Pachydeminae in the Palearctic region using dispersalvicariance analysis (DIVA, Ronquist, 1996, 1997). This method reconstructs the ancestral distribution in a given phylogeny based on a vicariance model, while allowing dispersal and extinction to occur. Unlike other methods, DIVA does not enforce area relationships to conform to a hierarchical “area cladogram” so it can be used to reconstruct “reticulate” biogeographic scenarios. DIVA optimal reconstructions suggest that the ancestor of Pachydeminae was originally present in the south-eastern Mediterranean region, including North Africa, the Middle East, the Iranian Plateau, and the Balkans/Anatolian region. During the Oligocene-Miocene, the collision between the Arabian, African, and Eurasian Plates resulted in the appearance of consecutive dispersal barriers (e.g., the Red Sea, the Zagros Mountains). This geographic division was followed by fragmentation (vicariance) of the ancestral biota, giving rise to several disjunct genera (Pachydema Castelnau, 1832, Hemictenius Reitter, 1897). The Middle East region and the Iranian Plateau acted as centers of diversification during the evolution of the subfamily: many of the least speciose genera of Pachydeminae originated within these two regions by sympatric speciation (Otoclinius Brenske, 1896). In contrast, the presence of Pachydeminae in the Western Mediterranean region (Iberian Peninsula and southwestern

Abstract: The study showed that in the Stipa grandis steppe of Inner Mongolia, there were 4 families and 9 species of Scarabaeoidea larvae, among which, the numbers of species and individuals of Melolonthidae were more than those of other families. The important value of the dominant species in Scarabaeoidea larvae community were Trematodes tenebrioides > Serica orientalis > Amphimallon solstitialis > Cyriopertha arcuata. Based on the features of their seasonal dynamics, they could be classified into three kinds. The first kind was that their density peak occurred in spring and autumn, such as Serica orientalis. Cyriopertha arcuata belonged to the second kind, and its density had no obvious fluctuation through all the year. Trematodes tenebrioides and Amphimallon solstitialis could be classified into the third kind, and their density peak all occurred in autumn. The biodiversity index of Scarabaeoidea larvae community was relatively higher in autumn than in spring and summer. Although the richness of Scarabaeoidea larvae populations was not lower in spring, their composition was very simple.
