DOLLFUSS A b s t r a c t : A Key to Old World species of Podalonia FERNALD 1927 is provided. Podalonia pulawskii new species, is described from Namibia, and South Africa. The following are new synonyms in Podalonia: pseudocaucasica BALTHASAR 1957 = alpina (KOHL 1888); nigriventris (GUSSAKOVSKIJ 1934) = affinis (W. KIRBY 1798); turcestanica (DALLA TORRE 1897) = andrei (F. MORAWITZ 1889); mahatma (R. TURNER 1918) = caucasica (MOCSÁRY 1883); mandibulata (W.F. KIRBY 1889) = ebenina (SPINOLA 1869); obo (TSUNEKI 1971) = flavida (KOHL 1888); merceti (KOHL 1906) = tydei (Le GUILLOU 1841). K e y w o r d s : Apoidea, Sphecidae, Podalonia, key. Introduction This study resulted from my attempts to identify the large collection of Podalonia in the Biologiezentrum Linz, Austria. I found that the only key to the Old World species was Kohl’s (1906) old treatment of the Palearctic fauna, supplemented by TSUNEKI’s (1971) key to the species of Mongolia. Dissections of male genitalia during my study revealed that these structures offer good species characters and I decided to produce a key to the Old World species. I have also included a key to genera. Thirty nine species are included in this paper, but I have excluded from the keys the species described by LI & YANG (P. parvula, P. pilosa and the male of P. yunnana) as I have not seen any material. Dr. Quiang Li kindly translated the Chinese descriptions into English for me and these are included under the species treatments. Also not included in the keys is P. hirticeps CAMERON (1889) whose type could not be located. I included BINGHAM’s (1897: 234) description of this species , and its description and figures by Jha and Farooqui (1994). Also missing from the key is Podalonia gulussa MORICE (1900) whose type is lost. James Hogan, Hope Entomological Collections, Oxford, wrote: "I am unable to find the type of Ammophila gulussa MORICE. It should be here and indeed the types of other species described in the same paper are here. I have searched the MORICE collection and there is no indication that P. gulussa was ever in the collection." Podalonia gulussa is probably a synonym of Podalonia ebenina. KOHL (1906: 274) separated P. gulussa from P. ebenina by the absence of a basal tooth on the claws. I have found that the basal tooth is reduced in some specimens of P. ebenina. © Biologiezentrum Linz/Austria; download unter www.biologiezentrum.at 1242 This study is based on the examination of 6,183 specimens. Terminology follows BOHART & MENKE (1976). The following are new synonyms: Podalonia pseudocaucasica BALTHASAR 1957 = alpina (KOHL 1888); P. nigriventris (GUSSAKOVSKIJ 1934) = affinis (W. KIRBY 1798); P. turcestanica (DALLA TORRE 1897) = andrei (F. MORAWITZ 1889); P. mahatma (R. TURNER 1918) = caucasica (MOCSÁRY 1883); P. mandibulata (W.F. KIRBY 1889) = ebenina (SPINOLA 1869); P. obo (TSUNEKI 1971) = flavida (KOHL 1888) and P. merceti (KOHL 1906) = tydei (Le GUILLOU 1841). One new species is described: Podalonia pulawskii DOLLFUSS nov.sp. from Namibia and South Africa. Note: Dark wings can get pale in old specimens and stylopized specimens have a shorter petiole than usual.

The sting of the Aculeata or stinging wasps is a modifed ovipositor; its function (killing or paralyzing prey, defense against predators) and the associated anatomical changes are apomorphic for Aculeata. The change in the purpose of the ovipositor/sting from being primarily an egg laying device to being primarily a weapon has resulted in modifcation of its handling that is supported by specifc morphological adaptations. Here, we focus on the sheaths of the sting (3rd valvulae = gonoplacs) in Aculeata, which do not penetrate and envenom the prey but are responsible for cleaning the ovipositor proper and protecting it from damage, identifcation of the substrate for stinging, and, in some taxa, contain glands that produce alarm pheromones.

GADALLAH Entomology Department, Faculty of Science, Cairo University, Giza, Egypt. E-mail: [email protected] Abstract An updated checklist of the Arabian species of Sphecidae is provided here. The list includes 70 identified valid species in 10 genera and four subfamilies: Ammophilinae (4 genera, 35 species), Chloriontinae (1 genus, 6 species), Sceliphrinae (2 genera, 8 species) and Sphecinae (3 genera, 21 species). Distributions, both on the Peninsula and extra-limital, are provided for each species and subspecies; four species (6%) are endemic to the Arabian Peninsula. Key words: Ammophilinae, Chloriontinae, Sceliphrinae, Sphecinae, distribution Sphecidae Latreille, 1802 The Sphecidae (s.s.) are a cosmopolitan family of wasps, comprising the digger wasps, mud daubers and other thread-waisted wasps. A total of 787 extant species in 19 genera and five subfamilies (Ammophilinae, Chlorion- tinae, Sceliphrinae, Sphecinae and Stangeellinae) are currently included in the family (Pulawski 2019). The largest genus, Ammophila W. Kirby, comprises 240 species, followed by Sphex Linnaeus (132 species) (Pulawski 2019), together forming about 47% of the total number of species. Species of the family Sphecidae can easily be distin- guished from other spheciform families by their petiolate metasoma and the large anal lobe of the hind wing (Bohart & Menke 1976; Finnamore 1993).

St::ttns of 15 Antioch Insects Listed in Notice of 75 Review by the U.S. Fish "l.nd Wildlife Service INTRODUCTION The sand dune formation east of Antioch, Contra Costa County, California, comprised the largest riverine dune system in California. Biogeographically, this formation was unique because it supported a northern extension of plants and animals of desert, rather than coastal, affinities. Geologists believe that the dunes were relicts of the most recent glaciation of the Sierra Nevada, probably originating 10,000 to 25,000 years ago, with the sand derived from the supratidal floodplain of the combined Sacramento and San Joaquin Rivers. The ice age climate in the area is thought to have been cold but arid. Presumably summertime winds sweeping through the Carquinez Strait across the glacial-age floodplains would have picked up the fine-grained sand and redeposited it to the east and southeast, thus creating the dune fields of eastern Contra Costa County.

    AN ABSTRACT OF THE DISSERTATION OF Reuben Gabriel Biel for the degree of Doctor of Philosophy in Zoology presented on September 12, 2017. Title: Coastal Dune Ecology, Geomorphology, and Ecosystem Services: How Invasive Beachgrasses, their Interactions, and Sediment Dynamics Shape U.S. Pacific Northwest Dunes Abstract approved: ________________________________________________________________________ Sally D. Hacker Biological invasions and climate change represent two preeminent threats to ecological communities and biodiversity, altering the distribution and abundance of species, disrupting existing species interactions and forming unprecedented ones, and creating novel ecological communities. Many of the most successful invasive species are also ecosystem engineers, species that physically modify the abiotic state of the ecosystem, and consequently have broad impacts on community structure, ecosystem processes, and ecosystem services. As ecosystems face dual hazards from biological invasions and climate change, it is imperative to understand what factors influence invasion success, how invasive species alter physical and biological processes, and how a changing climate alters the course of invasion. In this dissertation, I investigate the interactions of two invasive, dune-forming beachgrasses within the U.S Pacific Northwest coastal dune ecosystem and their influence on dune geomorphology and ecosystem services. Two species of non-native beachgrasses, Ammophila arenaria (L.) Link and A. breviligulata (Fernald), were intentionally introduced to the Pacific Northwest in the early 20th century for the purpose of sand stabilization. Since their introductions, they have displaced numerous endemic plants and animals, and facilitated the formation of tall, stable, and well-vegetated shore- parallel dune ridges throughout the region. However, the two Ammophila species differ in their distributions and their impacts on dunes: biogeographically, A.

  • Checklist of the Spheciform Wasps (Hymenoptera: Crabronidae & Sphecidae) of British Columbia
    Checklist of the Spheciform Wasps (Hymenoptera: Crabronidae & Sphecidae) of British Columbia Chris Ratzlaff Spencer Entomological Collection, Beaty Biodiversity Museum, UBC, Vancouver, BC This checklist is a modified version of: Ratzlaff, C.R. 2015. Checklist of the spheciform wasps (Hymenoptera: Crabronidae & Sphecidae) of British Columbia. Journal of the Entomological Society of British Columbia 112:19-46 (available at http://journal.entsocbc.ca/index.php/journal/article/view/894/951). Photographs for almost all species are online in the Spencer Entomological Collection gallery (http://www.biodiversity.ubc.ca/entomology/). There are nine subfamilies of spheciform wasps in recorded from British Columbia, represented by 64 genera and 280 species. The majority of these are Crabronidae, with 241 species in 55 genera and five subfamilies. Sphecidae is represented by four subfamilies, with 39 species in nine genera. The following descriptions are general summaries for each of the subfamilies and include nesting habits and provisioning information. The Subfamilies of Crabronidae Astatinae !Three genera and 16 species of astatine wasps are found in British Columbia. All species of Astata, Diploplectron, and Dryudella are groundnesting and provision their nests with heteropterans (Bohart and Menke 1976). Males of Astata and Dryudella possess holoptic eyes and are often seen perching on sticks or rocks. Bembicinae Nineteen genera and 47 species of bembicine wasps are found in British Columbia. All species are groundnesting and most prefer habitats with sand or sandy soil, hence the common name of “sand wasps”. Four genera, Bembix, Microbembex, Steniolia and Stictiella, have been recorded nesting in aggregations (Bohart and Horning, Jr. 1971; Bohart and Gillaspy 1985).
