Hymenoptera: Chalcidoidea: Leucospidae) from Kerala P A report on the occurrence of a parasitic wasp species Leucospis histrio Maindron, 1878 (Hymenoptera: Chalcidoidea: Leucospidae) from Kerala P. Girish Kumar1 and P.M. Sureshan2 Abstract A very rare parasitic wasp species Leucospis histrio Maindron, 1878 (Hymenoptera: Chalcidoidea: Leucospidae) is reported from Kerala. Introduction The family Leucospidae is a small A B group of parasitic wasps within the superfamily Chalcidoidea (Hymenoptera) composed exclusively of ectoparasitoids of aculeate wasps or bees. They mimic bees or stinging wasps in colour which is often black with yellow, red, or white markings, sometimes metallic, with robust mesosoma having strong sculptures.

  • A Visual Guide for the Identification of British Coelioxys Bees
    1 Introduction The Hymenoptera is an order of insects that includes bees, wasps, ants, ichneumons, sawflies, gall wasps and their relatives. The bees (family Apidae) can be recognised as such by the presence of feather-like hairs on their bodies, particularly near the wing bases. The genus Coelioxys Latreille belongs to the bee subfamily Megachilinae. There are six species of Coelioxys present in mainland Britain. Two other species are found in Guernsey but not mentioned in this pictorial key (C. afra Lepeletier and C. brevis Eversmann). Natural History Coelioxys (their various English names are: Sharp-tailed Bees, Sharp-abdomen Bees and Sharp-bellied Bees) are among those known as cuckoo bees because the larvae grow up on food stolen from Leaf-cutter Bees (Megachile Latreille) or Flower Bees (Anthophora Latreille). The genus Megachile probably includes the closest relatives of Coelioxys. Female Megachile construct nests of larval cells from leaves and provision each cell with a mixture of pollen and nectar for the young. A female Coelioxys will seek these out and apparently uses its sharp abdomen to pierce the cells. An egg is then laid in the Megachile cell. The egg of the Coelioxys hatches before that of the Megachile and the newly-hatched larva crushes the Megachile egg with its large jaws. The Coelioxys larva can then feed on the contents of the cell. Pupation occurs within a cocoon spun within the host cell where the larva overwinters as a prepupa. The genus Anthophora excavates nest burrows in sandy soil or rotting wood, where they may also become the hosts of Coelioxys larvae.

E-mail: [email protected] Abstract A new species, Polochridium spinosum Yue, Li & Xu, sp. nov. (China: Hunan, Shaanxi, Henan), is described and illus- trated. A key to the four Chinese species of Sapygidae is given. Key words: Sapyginae, new species, Palaearctic Region, Oriental Region Introduction Sapygidae is a small family of Vespoidea and includes 70 extant species in 12 genera (Aguiar et al. 2013; Achterberg 2014; Fernández & Sarmiento 2015), which are parasites of the bees Megachilidae, Apidae, Colletidae, rarely on wasps Eumeninae of Vespidae (Torchio 1979; Xu 1994; Kurzenko, 2012). Currently three species of the subfamily Sapyginae are known from China: Sapyga coma Yasumatsu & Sugihara, 1938, S. similis (Fabricius 1793), and Polochridium eoum Gussakovskij, 1932 (Kurzenko & Gusenleitner 1994; Xu 1994). Recently we collected in Hunan, Shaanxi and Henan fourteen females and one male of Polochridium, which described below as new species. Materials and methods Descriptions of the species have been made under a Leica MZ125 stereomicroscope, with lighting achieved through a 27W fluorescent lamp. Photographic images were produced with a digital camera Cool SNAP attached to the Zeiss Stemi 2000-cs stereomicroscope, and plates were finished with ACDSee 10.0 and Photoshop CS 8.0.1, mostly to adjust the size and background.

  • Beyond the Decline of Wild Bees: Optimizing Conservation Measures and Bringing Together the Actors
    insects Review Beyond the Decline of Wild Bees: Optimizing Conservation Measures and Bringing Together the Actors Maxime Drossart * and Maxence Gérard * Laboratory of Zoology, Research Institute for Biosciences, University of Mons (UMONS), Place du Parc 20, B-7000 Mons, Belgium * Correspondence: [email protected] (M.D.); [email protected] (M.G.) Received: 3 September 2020; Accepted: 18 September 2020; Published: 22 September 2020 Simple Summary: Wild bees represent the main group of pollinators in Europe, being responsible for the reproduction of numerous flowering plants. However, like a non-negligible part of biodiversity, this group has been facing a global decline mostly induced by numerous human factors over the last decades. Overall, even if all the questions are not solved concerning the causes of their decline, we are beyond the precautionary principle because the decline factors are roughly known, identified and at least partially quantified. Experts are now calling for effective actions to promote wild bee diversity and the enhancement of environmental quality. In this review, we present a general and up-to-date assessment of the conservation methods, as well as their efficiency and the current projects that try to fill the gaps and optimize the conservation measures. This publication aims to be a needed catalyst to implement concrete and qualitative conservation actions for wild bees. Abstract: Wild bees are facing a global decline mostly induced by numerous human factors for the last decades. In parallel, public interest for their conservation increased considerably, namely through numerous scientific studies relayed in the media. In spite of this broad interest, a lack of knowledge and understanding of the subject is blatant and reveals a gap between awareness and understanding.

HERATY1 & D. CHRISTOPHER DARLING2 1Department of Entomology, University of California, Riverside, CA, USA, 92521. E-mail: [email protected] 2Department of Entomology, Royal Ontario Museum, Toronto, Ontario, Canada, M5S 2C6 and Department of Ecology and Evolutionary Biology, University of Toronto, Toronto, Ontario, Canada, M5S 1A. E-mail: [email protected] Abstract Palaeocharis rex n. gen. and sp. (Eucharitidae: Eucharitinae) and Perilampus pisticus n. sp. (Perilampidae: Perilampinae) are described from Baltic amber. Perilampus renzii (Peñalver & Engel) is transferred to Torymidae: Palaeotorymus renzii n. comb. Palaeocharis is related to Psilocharis Heraty based on presence of one anellus, linear mandibular depression, dorsal axillular groove, free prepectus and a transverse row of hairs on the hypopygium. This fossil is unique in comparison with extant Chalcidoidea because there are two foretibial spurs instead of a single well- developed calcar. Perilampus pisticus is placed into the extant Perilampus micans group because the frenum and marginal rim of the scutellum are visible in dorsal view and the prepectus forms a large equilateral triangle. The phylogenetic placement of both genera is discussed based on an analysis of both a combined morphological and molecular (28S and 18S) and morphology-only matrix. Morphological characters were used from an earlier study of Eucharitidae (Heraty 2002), with some characters revised to reflect variation in Perilampinae. Baltic amber is of Eocene age, which puts the age of divergence of these families at more than 40 mya.

    POLLINATORS in Peril A systematic status review of North American and Hawaiian native bees Kelsey Kopec & Lori Ann Burd • Center for Biological Diversity • February 2017 Executive Summary hile the decline of European honeybees in the United States and beyond has been well publicized in recent years, the more than 4,000 species of native bees in North W America and Hawaii have been much less documented. Although these native bees are not as well known as honeybees, they play a vital role in functioning ecosystems and also provide more than $3 billion dollars in fruit-pollination services each year just in the United States. For this first-of-its-kind analysis, the Center for Biological Diversity conducted a systematic review of the status of all 4,337 North American and Hawaiian native bees. Our key findings: • Among native bee species with sufficient data to assess (1,437), more than half (749) are declining. • Nearly 1 in 4 (347 native bee species) is imperiled and at increasing risk of extinction. • For many of the bee species lacking sufficient population data, it’s likely they are also declining or at risk of extinction. Additional research is urgently needed to protect them. • A primary driver of these declines is agricultural intensification, which includes habitat destruction and pesticide use. Other major threats are climate change and urbanization. These troubling findings come as a growing body of research has revealed that more than 40 percent of insect pollinators globally are highly threatened, including many of the native bees critical to unprompted crop and wildflower pollination across the United States.

  • Trap-Nesting Bees and Wasps and Their Natural Enemies in Regenerated Broad-Leaved Forests in Central Japan
    「森林総合研究所研究報告」(Bulletin of FFPRI) Vol.18-No.1 (No.449) 189-194 March 2019 189 研究資料 (Research record) Trap-nesting bees and wasps and their natural enemies in regenerated broad-leaved forests in central Japan Shun'ichi MAKINO1)* and Kimiko OKABE1) Abstract Trap-nests are useful tools to monitor solitary bees and wasps that nest in tube-like cavities. We installed trap- nests made from internode tubes of bamboos and reeds in ten secondary deciduous broad-leaved stands of different ages of one to over 100 years after clear-cutting. Thirty-two species (eight families of Hymenoptera and one of Diptera) were obtained with the trap-nests: 20 host species and 12 of their natural enemies. The species richness of most families of hosts and natural enemies, except for Pompilidae, was higher in younger to middle-aged stands than in older ones over 70 years old. On the contrary, the family Pompilidae (spider wasps) proliferated in both young and old stands, with its relative abundance becoming greater with the increase in stand age.
