FAMILY DERODONTIDAE (Tooth-necked fungus beetles) D.E. Bright The family Derodontidae includes four genera and 19 species of small beetles that occur in the temperate parts of both the Northern and Southern Hemispheres. They are rarely encountered in the field and are uncommon in collections. Three genera and eight species are found in Canada and Alaska. With the exception of Laricobius species, members of this family feed as both larvae and adults on various kinds of fungi or the products of fungal metabolism. Peltastica appear to be restricted to fermenting sap flows or to areas under bark where bacterial or fungal fermentation is taking place. Derodontus species feed on the fruiting bodies of a wide range of higher Basidiomycetes. Fresh fruiting bodies are preferred by the beetles, although they have been recorded from rotting mushrooms, "slimy fungus" and "watery fungus". The feeding habits of Laricobius erichsonii have been well documented by Franz (1958). Adults and larvae feed on the pine and spruce aphids in the family Adelgidae. The preferred host of L. erichsonii is the balsam woolly aphid and the species was introduced into eastern Canada in the 1950's for the control of this pest. The other species of Laricobius also feed on other species of Adelgidae. Information on adult and larval morphology, feeding behavior, life cycle, evolution and keys and diagnosis of all genera and species may be found by consulting Lawrence and Hlavac (1979).

Emergence of Laricobius Nigrinus (Fender) (Coleoptera: Derodontidae) in the North Georgia Mountains1
Emergence of Laricobius nigrinus (Fender) (Coleoptera: Derodontidae) in the North Georgia Mountains1 C.E. Jones2, J.L. Hanula3, and S. K. Braman4 Dept. of Entomology, University of Georgia, 41 3 Biological Sciences Building, Athens, Georgia 30602, USA J. Entomol. Sci. 49(4): 401-412 (October 2014} Abstract Hemlock woolly adelgid, Adelges tsugae An nand, is currently found throughout most of the range of eastern hemlock, Tsuga canadensis (L. ) Carriere. Biological control agents have been released in attempts to control this pest, but how different climates influence the efficacy and survival of these agents has not been studied. One predatory beetle of A. tsugae, Laricobius nigrinus Fender, is native to the Pacific Northwest and, therefore, experiences a much different summer climate in the north Georgia mountains. To better understand survival of this predator as it aestivates in the soil, 5 mesh cages were set up at each of 16 sites with 4 sites located at an elevation below 549 m, 4 sites between 549 m - 732 m, 5 sites between 732 m - 914 m, and 3 sites over 914 m. At each site 30 larvae were placed inside one of the cages during March, April, or May on a bouquet of adelgid infested hemlock twigs, and emergence of adults was monitored in the fall . Of the 1440 larvae placed at the 16 sites, only 4 adult beetles emerged between 06 October 2012 and 05 November 2012. The overall success rate remains unknown, and more research is needed to assess the efficacy of L. nigrinus as a biological control agent in Georgia.

Genome Sequencing of Rhinorhipus Lawrence Exposes an Early Branch
Kusy et al. Frontiers in Zoology (2018) 15:21 https://doi.org/10.1186/s12983-018-0262-0 RESEARCH Open Access Genome sequencing of Rhinorhipus Lawrence exposes an early branch of the Coleoptera Dominik Kusy1, Michal Motyka1, Carmelo Andujar2, Matej Bocek1, Michal Masek1, Katerina Sklenarova1, Filip Kokas3, Milada Bocakova1, Alfried P. Vogler4,5 and Ladislav Bocak1* Abstract Background: Rhinorhipidae Lawrence, 1988 is an enigmatic beetle family represented by a single species, Rhinorhipus tamborinensis Lawrence, 1988, from Australia, with poorly established affinities near the superfamily Elateroidea (click beetles, soldier beetles and fireflies) or the more inclusive series (infraorder) Elateriformia. Its evolutionary position may inform the basal relationships of the suborder Polyphaga, the largest clade of Coleoptera. Results: We analyzed four densely sampled DNA datasets of major coleopteran lineages for mitogenomes, rRNA genes and single copy nuclear genes. Additionally, genome sequencing was used for incorporation of R. tamborinensis into a set of 4220 orthologs for 24 terminals representing 12 polyphagan superfamilies. Topologies differed to various degrees, but all consistently refute the proposed placement of Rhinorhipidae in Elateroidea and instead indicate either sister relationships with other Elateriformia, frequently together with Nosodendridae, another divergent small family hitherto placed in Derodontoidea, or in an isolated position among the deepest lineages of Polyphaga. The phylogenomic analyses recovered Rhinorhipus in a sister position to all other Elateriformia composed of five superfamilies. Therefore, we erect the new superfamily Rhinorhipoidea Lawrence, 1988, stat. Nov.,with the type-family Rhinorhipidae. The origins of the Rhinorhipidae were dated to the Upper Triassic/Lower Jurassic at the very early phase of polyphagan diversification.

A survey of beetle faunal diversity and composition was studied in Durgapur Municipal Corporation, Durgapur, West Bengal, from January to December 2012. Beetles were collected using standard trapping methods from three different sites selected on the basis of their specific habitat differences, identified up to the level of family, and counted monthly. A total of 9 families were reported from the study site. The second site, that is, Site B, showed the highest diversity. It is also noted that the highest diversity wasfound during monsoon in all the three sites. 1. Introduction dead or decaying ones [7].

Biodiversity of New Zealand beetles (Insecta: Coleoptera). Memoirs of the Museum of Victoria 56(2): 659-666. Approximately 5235 species are described for New Zealand, including 354 introduced. They belong to 82 families in two suborders, Adephaga and Polyphaga. The New Zealand beetle fauna is distinguished by the absence of many major lineages, a high level of endem- ism. which in many groups is over 90% at the specific level and over 43% at the generic level (e.g.. Staphylinidae), and the radiation of many groups of genera and species. The origins of New Zealand's beetle fauna are still poorly understood. They are likely to be varied, includ- ing Gondwanan elements and elements which arrived here by short and long-distance dispersal recently and in the remote past. The size of the New Zealand beetle fauna is con- sistent with species number/land area relationships in other areas around the world.

Chapter 16. Evaluating Host Range of Laricobius Nigrinus for Introduction Into the Eastern United States for Biological Control of Hemlock Woolly Adelgid
ASSESSING HOST RANGES OF PARASITOIDS AND PREDATORS _________________________________ CHAPTER 16. EVALUATING HOST RANGE OF LARICOBIUS NIGRINUS FOR INTRODUCTION INTO THE EASTERN UNITED STATES FOR BIOLOGICAL CONTROL OF HEMLOCK WOOLLY ADELGID G. Zilahi-Balogh Agriculture & Agri-Food Canada, Harrow, Ontario, Canada [email protected] HEMLOCK WOOLLY ADELGID IN NORTH AMERICA The hemlock woolly adelgid (HWA), Adelges tsugae Annand (Homoptera: Adelgidae), is a serious threat to hemlock landscape and forest stands in the eastern United States (McClure, 1996). Eastern hemlock (Tsuga canadensis [L.] Carr.) and Carolina hemlock (Tsuga caroliniana Engelm.) are very susceptible to HWA attack, and infested trees have died in as little as four years (McClure, 1991). DISTRIBUTION OF HWA HWA is believed to have originated in Asia (McClure, 1987), and was first observed in North America in the Pacific Northwest in the early 1920s, where Annand (1924) described it from specimens collected on western hemlock, Tsuga heterophylla (Raf.) Sargent, in Oregon. An earlier description in 1922 identified the species as Chermes funitectus Dreyfus, also from west- ern hemlock in Vancouver, British Columbia (Annand, 1928). Annand (1928) reported that the two species were the same. HWA is exotic to eastern North America (McClure, 1987). First collected in the eastern United States in Virginia in 1951 in an ornamental setting (Stoetzel, 2002), it has spread to forests where it currently occurs in parts of 16 states along the eastern seaboard from North Carolina to New England (USDA FS, 2004). The main front of the HWA infestation is ad- vancing at approximately 25 km per year (McClure, 2001). There are nine recognized species of hemlock (Farjon, 1990).

Observations on the Cave-Associated Beetles (Coleoptera) of Nova Scotia, Canada Max Moseley1

Observations on the Cave-Associated Beetles (Coleoptera) of Nova Scotia, Canada. International Journal of Speleology, 38(2), 163-172. Bologna (Italy). ISSN 0392-6672. The cave-associated invertebrates of Nova Scotia constitute a fauna at a very early stage of post-glacial recolonization. The Coleoptera are characterized by low species diversity. A staphylinid Quedius spelaeus spelaeus, a predator, is the only regularly encountered beetle. Ten other terrestrial species registered from cave environments in the province are collected infrequently. They include three other rove-beetles: Brathinus nitidus, Gennadota canadensis and Atheta annexa. The latter two together with Catops gratiosus (Leiodidae) constitute a small group of cave-associated beetles found in decompositional situations. Quedius s. spelaeus and a small suite of other guanophiles live in accumulations of porcupine dung: Agolinus leopardus (Scarabaeidae), Corticaria serrata (Latrididae), and Acrotrichis castanea (Ptilidae). Two adventive weevils Otiorhynchus ligneus and Barypeithes pellucidus (Curculionidae) collected in shallow cave passages are seasonal transients; Dermestes lardarius (Dermestidae), recorded from one cave, was probably an accidental (stray). Five of the terrestrial beetles are adventive Palaearctic species. Aquatic beetles are collected infrequently. Four taxa have been recorded: Agabus larsoni (Dytiscidae) may be habitual in regional caves; another Agabus sp. (probably semivittatus), Dytiscus sp. (Dytiscidae), and Crenitis digesta (Hydrophilidae) are accidentals. The distribution and ecology of recorded species are discussed, and attention is drawn to the association of beetles found in a Nova Scotia “ice cave”.

Coleoptera, Derodontidae, Juropeltastica gen. n., fossil, Daohugou beds, Middle Jurassic, China Abstract. The first fossil tooth-necked fungus beetle, Juropeltastica sinica gen. n. sp. n., is described and illustrated based on a single impression fossil from the Middle Jurassic Daohugou beds (ca. 165 Ma) of northeastern China. it represents the first definitive fossil be- longing to the extant family Derodontidae. Juropeltastica is placed in Derodontidae based on its overall body shape and size, head with complex systems of tubercles and grooves, pronotum with dentate lateral carinae, open mesocoxal cavities bordered by mesepimeron and metanepisternum, excavate metacoxae, and 5-segmented abdomen. The occurrence of a reliable derodontid fossil from 165 mil- lion years ago places Derodontidae among the small but growing number of beetle families of known Middle Jurassic age, which is important in the dating of phylogenetic trees.
