A summary list of fossil spiders. In Platnick, N. I. (ed.) The world spider catalog, version 10.5. American Museum of Natural History, online at http://research.amnh.org/entomology/spiders/catalog/index.html Last udated: 10.12.2009 INTRODUCTION Fossil spiders have not been fully cataloged since Bonnet’s Bibliographia Araneorum and are not included in the current Catalog. Since Bonnet’s time there has been considerable progress in our understanding of the spider fossil record and numerous new taxa have been described. As part of a larger project to catalog the diversity of fossil arachnids and their relatives, our aim here is to offer a summary list of the known fossil spiders in their current systematic position; as a first step towards the eventual goal of combining fossil and Recent data within a single arachnological resource. To integrate our data as smoothly as possible with standards used for living spiders, our list follows the names and sequence of families adopted in the Catalog. For this reason some of the family groupings proposed in Wunderlich’s (2004, 2008) monographs of amber and copal spiders are not reflected here, and we encourage the reader to consult these studies for details and alternative opinions. Extinct families have been inserted in the position which we hope best reflects their probable affinities. Genus and species names were compiled from established lists and cross-referenced against the primary literature.

  • Insects in Amber
    Annu. Rev. Entomol. 1993.46:145-59 Copyright © 1993 by Annual Reviews Inc. All righis reserved INSECTS IN AMBER George O. Poinar, Jr. Department of Entomological Sciences, University of California, Berkeley, California 94720 KEY WORDS: fossil insects, tissue preservation, paleoentomology, paleosymbiosis, paleoen­ vironments Introduction Aside from their beauty, insects in amber represent the finest fossil remains of the Insecta and offer numerous opportunities to study microevolution, biogeography, mimicry, behavior, environmental reconstruction, extinction, paleosymbiosis, and molecular phylogeny. Amberization (changes involved in the process of forming amber from fresh resin) is a gentle process inducive to the preservation of insects that are small, delicate, and soft-bodied. It is the most complete type of fossilization known for insects, and by preserving the three-dimensional form, color pattern, and minute details of the exoskeleton, such fossils can be easily compared with their extant descendants. The study of amber insects was initiated over 200 years ago with the fIrst investigation of the Baltic amber fauna and flora (10). Indeed, most of the descriptions of amber insects today pertain to Baltic deposits. However, in the past 50 years, workers have begun to explore additional amber deposits. These are listed in Table 1. Access provided by Oregon State University on 12/22/16. For personal use only. The oldest amber deposits containing insects are from the Middle East and Annu. Rev. Entomol. 1993.38:145-159. Downloaded from www.annualreviews.org are commonly known as Lebanese amber. They date from the Early Cretaceous and extend back 135 million years. In the past 20 years, attention has centered on the highly fossiliferous Tertiary amber deposits in the Dominican Republic, which are fairly extensive and provide a steady income for Dominican workers primarily through sale for use as jewelry.

  • Fossil Ants (Hymenoptera: Formicidae): Ancient Diversity and the Rise of Modern Lineages
    Myrmecological News 24 1-30 Vienna, March 2017 Fossil ants (Hymenoptera: Formicidae): ancient diversity and the rise of modern lineages Phillip BARDEN Abstract The ant fossil record is summarized with special reference to the earliest ants, first occurrences of modern lineages, and the utility of paleontological data in reconstructing evolutionary history. During the Cretaceous, from approximately 100 to 78 million years ago, only two species are definitively assignable to extant subfamilies – all putative crown group ants from this period are discussed. Among the earliest ants known are unexpectedly diverse and highly social stem- group lineages, however these stem ants do not persist into the Cenozoic. Following the Cretaceous-Paleogene boun- dary, all well preserved ants are assignable to crown Formicidae; the appearance of crown ants in the fossil record is summarized at the subfamilial and generic level. Generally, the taxonomic composition of Cenozoic ant fossil communi- ties mirrors Recent ecosystems with the "big four" subfamilies Dolichoderinae, Formicinae, Myrmicinae, and Ponerinae comprising most faunal abundance. As reviewed by other authors, ants increase in abundance dramatically from the Eocene through the Miocene. Proximate drivers relating to the "rise of the ants" are discussed, as the majority of this increase is due to a handful of highly dominant species. In addition, instances of congruence and conflict with molecular- based divergence estimates are noted, and distinct "ghost" lineages are interpreted. The ant fossil record is a valuable resource comparable to other groups with extensive fossil species: There are approximately as many described fossil ant species as there are fossil dinosaurs. The incorporation of paleontological data into neontological inquiries can only seek to improve the accuracy and scale of generated hypotheses.

  • Sitemate Recognition: the Case of Anochetus Traegordhi (Hymenoptera; Formicidae) Preying on Nasutitermes (Isoptera: Termitidae) by B
    569 Sitemate Recognition: the Case of Anochetus traegordhi (Hymenoptera; Formicidae) Preying on Nasutitermes (Isoptera: Termitidae) by B. Schatz', J. Orivel2, J.P. Lachaud", G. Beugnon' & A. Dejean4 ABSTRACT Workers of the ponerine ant Anochetus traegordhi are specialized in the capture of Nasutitermes sp. termites. Both species were found to live in the same logs fallen on the ground of the African tropical rain forest. A. traegordhi has a very marked preference for workers over termite soldiers. The purpose of the capture of soldiers, rather than true predation, was to allow the ants easier access to termite workers. During the predatory sequence, termite workers were approached from behind, then seized and stung on the gaster, while soldiers were attacked head on and stung on the thorax. When originating from a different nest-site log than their predator ant, termites were detected from a greater distance and even workers were attacked more cau- tiously. Only 33.3% of these termite workers were retrieved versus 75% of the attacked same-site termite workers. We have demonstrated that hunting workers can recognize the nature of the prey caste (workers versus termite soldiers) and the origin of the termite colony (i.e. sharing or not the log where the ants were nesting), supporting the hypothesis that hunting ants can learn the colony odor of their prey. This, in addition to the nest-site selection of A. traegordhi in logs occupied by Nasutitermes can be considered as a first step in termitolesty. Key words: Anochetus, Nasutitermes prey recognition, predatory behavior. INTRODUCTION During their 100 million years of coexistence, ants and termites have been engaged in a coevolutionary arms race, with ants acting as the aggressor and employing many predatory strategies while termites are the prey presenting several defensive reactions (1-11511dobler & Wil- 'LEPA, CNRS-UMR 5550, Universite Paul-Sabatier, 118 route de Narbonne, 31062 Toulouse cedex, France (e-mail: schatz©cict.fr)(correspondence author: B.

  • ANT BELONOPELTA DELETRIX MANN Author Near the Village Of
    ECOLOGY AND BEHAVIOR OF ANT BELONOPELTA DELETRIX MANN (HYMENOPTERA FORMICIDAE) BY EDWARD O. WILSON Biological Laboratories, Harvard University Belonopelta Mayr is a little-known genus of ponerine ants represen.ted by two species, B. attenuata Mayr of Colombia and B. deletrix Mann, the latter hitherto re- corded fro,m Honduras and Chiapas (Wheeler, 1935; Brown, 1950). It is of more than usual interest because of the aberrant, presumably raptorial modification of the mandibles. To the present time only several s.pecimens have been mentioned in the literature, and nothing has been recorded concerning its biology. B. deletrix was recently encountered by the present author near the village of Pueblo Nuevo, Veracruz, in the Cosolapa Valley ten miles south of Cosolapa. This record represents a considerable northwestward extension f the range of the genus. The Cosolapa Valley, like most o.f this part of Mexico, is under heavy cultivation, and the native forest is limited to precari,ous sanctuaries on the steep slopes of numerous hills and mountains which rise from the valley floor. Pueblo Nuevo is located in the saddle of a pass through one o,f the lower hill ranges. To the northwest, and across the nearby Cosolapa River, there is a large tract of true rainforest, i.e., a forest in which the trees are several-storied, with a few "emergents" over 100 feet in height, and heavily festooned in the up- per reaches by lianas and epiphytes. The upper stratum forms a closed canopy in the undisturbed portions, and herbaceous undergrowth is very sparse. The forest is being continuously high-graded by crude native lumber- ing methods, and as a result clearings and patches of scrubby second growth occur throughout.

  • Amber! Conrad C
    AMBER! CONRAD C. LABANDEIRA! Department of Paleobiology, National Museum of Natural History, Smithsonian Institution Washington, D.C. 20013 USA ˂[email protected]! ˃ and! Department of Entomology, University of Maryland, College Park, MD 20742 USA ABSTRACT.—The amber fossil record provides a distinctive, 320-million-year-old taphonomic mode documenting gymnosperm, and later, angiosperm, resin-producing taxa. Resins and their subfossil (copal) and fossilized (amber) equivalents are categorized into five classes of terpenoid, phenols, and other compounds, attributed to extant family-level taxa. Copious resin accumulations commencing during the early Cretaceous are explained by two hypotheses: 1) abundant resin production as a byproduct of plant secondary metabolism, and 2) induced and constitutive host defenses for warding off insect pest and pathogen attack through profuse resin production. Forestry research and fossil wood-boring damage support a causal relationship between resin production and pest attack. Five stages characterize taphonomic conversion of resin to amber: 1) Resin flows initially caused by biotic or abiotic plant-host trauma, then resin flowage results from sap pressure, resin viscosity, solar radiation, and fluctuating temperature; 2) entrapment of live and dead organisms, resulting in 3) entombment of organisms; then 4) movement of resin clumps to 5) a deposition site. This fivefold diagenetic process of amberization results in resin→copal→amber transformation from internal biological and chemical processes and external geological forces. Four phases characterize the amber record: a late Paleozoic Phase 1 begins resin production by cordaites and medullosans. A pre-mid-Cretaceous Mesozoic Phase 2 provides increased but still sparse accumulations of gymnosperm amber. Phase 3 begins in the mid-early Cretaceous with prolific amber accumulation likely caused by biotic effects of an associated fauna of sawflies, beetles, and pathogens.

Ants are the most widely distributed and most numerically abundant group of social insects. First, they were ground- or litter-dwelling predators or scavengers, and certain taxa evolved to adopt an arboreal way of life. Most ant species are generalist feeders, and only some ground-nesting and ground- foraging species are strictly predators. Ants are central-place foragers (with the exception of army ants during the nomadic phase) that may use different foraging strategies. Solitary hunting is the most common method employed by predatory ants. Cooperative hunting, considered more evolved than solitary hunting, is used by army ants and other ants such as Myrmicaria opaciventris, Paratrechina longicornis or the dominant arboreal Oecophylla. Army ants are predators with different levels of specialization, some of which focus on a particular genus or species, as is the case for Nomamyrmex esenbeckii which organizes subterranean raids on the very large colonies of the leaf-cutting species Atta colombica or A. cephalotes. Arboreal ants have evolved predatory behaviors adapted to the tree foliage, where prey are unpredictable and able to escape by flying away, jumping or Correspondence/Reprint request: Dr.
