Alpine Entomology 9: 5-28 DOI: 10.3897/alpento.9.147831 Authors: Michael Balke, Adrián Villastrigo, Jiří Hájek, Suriani Surbakti, Rawati Panjaitan, Lars Hendrich Abstract: The genus Limbodessus Guignot, 1939 from New Guinea is reviewed. Eight new species are described from the Central Mountain Range of New Guinea, from altitudes of 1,800 up to 3,500 m above sea level: Limbodessus aipo sp. nov., L. aldente sp. nov., L. elit sp. nov., L. habbema sp. nov., L. juliana sp. nov., L. konoensis sp. nov., L. paniai sp. nov., and L. wilhelmina sp. nov. Limbodessus skalei Hendrich, Surbakti & Balke, 2020, described from Waigeo Island, is recorded for the first time for New Guinea. All 13 species are illustrated. They can be separated from each other by size, body shape, dorsal coloration, punctation of dorsal surface, but predominantly by the form of the male and female antennomeres and the form of male genitalia. A modified key is presented, and the habitats of most species are illustrated in detail. HTML XML PDF

Alpine Entomology 9: 1-3 DOI: 10.3897/alpento.9.151006 Authors: Oliver Hawlitschek, Nikita Sevastianov, Jan-Henrik Pamin, Martin Husemann Abstract: Same-sex and interspecific sexual behavior have been documented in arthropods, but records remain very scarce. We report a mating attempt of a male Dociostaurus kraussi (Ingenitzky, 1897) (Gomphocerinae) and a male of Oedaleus decorus (Germar, 1825) (Oedipodinae), both grasshoppers (Orthoptera: Acrididae), from the region of the Dzungarian Alatau Mountains in Kazakhstan. A Disc3D scan showed that the cerci of the D. kraussi male clearly connect to the external genitalia of the O. decorus male, but we could not ascertain if the genitalia were inserted or if any sperm was transferred. We consider erroneous recognition the most likely explanation but discuss other potential reasons, concluding that much remains to be learned about the highly complex reproductive behavior of acridid grasshoppers.

Alpine Entomology 8: 153-160 DOI: 10.3897/alpento.8.138225 Authors: Thomas J. Wood, Christophe J. Praz Abstract: Anthophora onosmarum is a poorly known bee species described from the Caucasus (Georgia). New fieldwork has revealed that the species is present in Bulgaria and Greece, and is also widespread across Turkey, predominantly on the Anatolian plateau. New behavioural data shows that A. onosmarum is likely narrowly oligolectic on the plant genus Onosma (Boraginaceae), and is capable of buzzing flowers to release pollen. This finding illustrates the growing trend of overlooked bee species with more Caucasian, Anatolian, or even Middle Eastern distributions occurring in under-surveyed mountainous parts of the Southern Balkans.
