Onthophagus fragosus n.sp. a second endemic species of Onthophagus Latreille from Cuba (Coleoptera : Scarabaeidae, Scarabaeinae).
Onthophagus fragosus, a new species of Onthophagus, is described from Cienfuegos Province on the island of Cuba. Specimens were collected in leaf litter samples at elevations of 650-935 m. It appears to be most closely related to O. marginatus Castelnau, the only other Cuban endemic Onthophagus species. Images of habitus and of male genitalia are provided.
متن کاملHormonal control of male horn length dimorphism in the dung beetle Onthophagus taurus (Coleoptera: Scarabaeidae).
Male dung beetles (Onthophagus taurus) facultatively produce a pair of horns that extend from the base of the head: males growing larger than a threshold body size develop long horns, whereas males that do not achieve this size grow only rudimentary horns or no horns at all. Here we characterize the postembryonic development of these beetles, and begin to explore the hormonal regulation of horn...
متن کاملAfrican dung beetle Onthophagus gazella Fabricius (Coleoptera: Scarabaeidae) esterase isozymes.
African beetles Onthophagus gazella from both sexes were analyzed by electrophoresis for an investigation of esterase isozymes using alpha-naphthyl propionate and methylumbelliferyl propionate as substrates. Only one of the esterases (Est. 6) reacted with one of the substrates (alpha-naphthyl propionate). Six areas of activity were found, two of them being polymorphic (Est. 3 and Est. 4). For p...
متن کاملNew Guinea Onthophagus: taxonomy of ten small, unicolored new species (Coleoptera: Scarabaeidae: Scarabaeinae).
The taxonomy of small, unicolor brown to black Papuasian species of the genus Onthophagus Latreille, 1802 is discussed. Two multi-species groups are defined in the nominotypical subgenus Onthophagus, one with broad and one with narrow dorsal eye foramina (O. acerus and O. kokodentatus groups, respectively). Twelve species are listed, keyed, and diagnosed. Ten of these are new species from Papua...
متن کاملDiet alters male horn allometry in the beetle Onthophagus acuminatus (Coleoptera: Scarabaeidae
Darwin considered the horns of male beetles to be among the most striking examples of sexual selection. As with antlers in deer or elk, beetle horns scale positively with male body size, with the result that large males have disproportionately longer horns than small males. It is generally assumed that such scaling relationships ('static allometries') are insensitive to short-term changes in th...
