The seasonal activity of the adult Scarabaeid (Laparosticti) beetles was monitored in 2004 and 2006 in two locations situated in different altitudes (600 m and 900 m) near Dagmarmara, Manisa province, western Turkey. Totally 33 species belonging to the families Aphodiidae, Geotrupidae and Scarabaeidae of coprophagous Scarabaeoidea are recorded in cow dung in the two localities. In the first four species with the following numbers as percentage of the total catch: Aphodius (s. str.) fimetarius (Linnaeus, 1758), 19.2 %; Onthophagus (Palaeonthophagus) ruficapillus Brullé, 1832, 18.8 %; Onthophagus (s. str.) taurus (Schreber, 1759), 12 % and Onthophagus (Palaeonthophagus) medius (Kugelann, 1792), 8.7 %. Seasonal dynamics of these recorded species are evaluated and compared with published results from mainly Europe. Source

The new species Parachorius semsanganus sp. n. is described from Laos. This enigmatic Oriental deltochiline represents a "morphological link" between Parachorius and Cassolus by sharing characters of the two genera. The fact that P. semsanganus cannot be unequivocally placed in either of these two genera stresses some more general problems of the current classification of Parachorius and Cassolus. Such problems can be solved only in the course of phylogenetic analysis, the need of which is briefly outlined. © S. Tarasov, D. Keith. Source

An overview of the genus Pharaonus Blanchard, 1851 is presented. Pharaonus farsensis new species and P. adelphus new species are described from Iran, P. lederi turcmenius Ohaus, 1941 is recognized as new synonym of P. lederi (Reitter, 1888), and the subgenus Tamerlanius new subgenus is proposed for the two central-Asian species. New distribution records and systematic notes are presented: P. caucasicus (Reitter, 1888) is removed from the fauna of Iran and P. varicoloreus (Burmeister, 1844) from that of Israel; P. fasciculatus (Burmeister, 1844) is reported for the first time from Israel, P. semenowi (Reitter, 1888) from Tajikistan. All known species are illustrated and a key to species is presented. Copyright © 2015 Magnolia Press. Source

Several species of glaphyrid (Scarabaeoidea: Glaphyridae) beetles forage and mate on Mediterranean red bowl-shaped flowers. In red anemones and poppies in Israel, female beetles occupy only a subset of the flowers, do not aggregate, and are hidden below the petals. This raises the question of how males find their mates. In the present study, we investigated the hypothesis that males and females orient to similar plant-generated cues, thereby increasing their mate encounter prospects. Previous studies have demonstrated that beetle attraction to red models increases with display area. Choice tests with flowers and with models indicate that both male and female beetles prefer large displays. In anemones, beetles rest, feed, and mate mainly on male-phase flowers, which are larger than female-phase flowers. Poppies that contain beetles are larger than the population average. These findings support the hypothesis that males and females meet by orienting to large red displays. Corolla size correlates with pollen reward in both plant species, suggesting that visits to large flowers also yield foraging benefits. Male beetles often jump rapidly among adjacent flowers. By contrast to the preference for large flowers by stationary individuals, these jump sequences are random with respect to flower sex-phase (in anemone) and size (in poppy). They may enable males to detect females at close range. We hypothesize that males employ a mixed mate-searching strategy, combining orientation to floral signals and to female-produced cues. The glaphyrids' preference for large flowers may have selected for extraordinarily large displays within the 'red anemone' pollination guild of the Levant. © 2010 The Linnean Society of London.
