Published online at www.senckenberg.de/arthropod-systematics on May 17, 2019. Published in print on June 03, 2019. Editors in charge: Andy Sombke & Klaus-Dieter Klass. Abstract. The mesosomal skeletomuscular system of workers of Myrmecia nigrocincta was examined. A broad spectrum of methods was used, including micro-computed tomography combined with computer-based 3D reconstruction. An optimized combination of advanced techniques not only accelerates the acquisition of high quality anatomical data, but also facilitates a very detailed documentation and vi- sualization. This includes fne surface details, complex confgurations of sclerites, and also internal soft parts, for instance muscles with their precise insertion sites. Myrmeciinae have arguably retained a number of plesiomorphic mesosomal features, even though recent mo- lecular phylogenies do not place them close to the root of ants. Our mapping analyses based on previous morphological studies and recent phylogenies revealed few mesosomal apomorphies linking formicid subgroups. Only fve apomorphies were retrieved for the family, and interestingly three of them are missing in Myrmeciinae. Nevertheless, it is apparent that profound mesosomal transformations took place in the early evolution of ants, especially in the fightless workers.

  • The Structure of Cynipid Oak Galls: Patterns in the Evolution of an Extended Phenotype
    The structure of cynipid oak galls: patterns in the evolution of an extended phenotype Graham N. Stone1* and James M. Cook2 1Department of Zoology, University of Oxford, South Parks Road, Oxford OX1 3PS, UK ([email protected]) 2Department of Biology, Imperial College, Silwood Park, Ascot, Berkshire SL5 7PY, UK Galls are highly specialized plant tissues whose development is induced by another organism. The most complex and diverse galls are those induced on oak trees by gallwasps (Hymenoptera: Cynipidae: Cyni- pini), each species inducing a characteristic gall structure. Debate continues over the possible adaptive signi¢cance of gall structural traits; some protect the gall inducer from attack by natural enemies, although the adaptive signi¢cance of others remains undemonstrated. Several gall traits are shared by groups of oak gallwasp species. It remains unknown whether shared traits represent (i) limited divergence from a shared ancestral gall form, or (ii) multiple cases of independent evolution. Here we map gall character states onto a molecular phylogeny of the oak cynipid genus Andricus, and demonstrate three features of the evolution of gall structure: (i) closely related species generally induce galls of similar structure; (ii) despite this general pattern, closely related species can induce markedly di¡erent galls; and (iii) several gall traits (the presence of many larval chambers in a single gall structure, surface resins, surface spines and internal air spaces) of demonstrated or suggested adaptive value to the gallwasp have evolved repeatedly. We discuss these results in the light of existing hypotheses on the adaptive signi¢cance of gall structure. Keywords: galls; Cynipidae; enemy-free space; extended phenotype; Andricus layers of woody or spongy tissue, complex air spaces within 1.

However, the mechanisms leading to reproductive isolation, the genes involved in adaptive divergence, and the traits that shape the adaptation of wild species to changes in climate are still largely unknown. In studying the role of ecological interactions and environment-driven selection, trees have emerged as potential model organisms because of their longevity and large genetic diversity, especially in natural habitats. Due to recurrent gene flow among species with different ecological preferences, oaks arose as early as the 1970s as a model for understanding how speciation can occur in the face of interspecific gene flow, and what we mean by “species” when geographically and genomically heterogeneous introgression seems to undermine species’ genetic Citation: Lazic, D.; Hipp, A.L.; coherence.

  • THE TRUE ARMY ANTS of the INDO-AUSTRALIAN AREA (Hymenoptera: Formicidae: Dorylinae)
    Pacific Insects 6 (3) : 427483 November 10, 1964 THE TRUE ARMY ANTS OF THE INDO-AUSTRALIAN AREA (Hymenoptera: Formicidae: Dorylinae) By Edward O. Wilson BIOLOGICAL LABORATORIES, HARVARD UNIVERSITY, CAMBRIDGE, MASS., U. S. A. Abstract: All of the known Indo-Australian species of Dorylinae, 4 in Dorylus and 34 in Aenictus, are included in this revision. Eight of the Aenictus species are described as new: artipus, chapmani, doryloides, exilis, huonicus, nganduensis, philiporum and schneirlai. Phylo­ genetic and numerical analyses resulted in the discarding of two extant subgenera of Aenictus (Typhlatta and Paraenictus) and the loose clustering of the species into 5 informal " groups" within the unified genus Aenictus. A consistency test for phylogenetic characters is discussed. The African and Indo-Australian doryline species are compared, and available information in the biology of the Indo-Australian species is summarized. The " true " army ants are defined here as equivalent to the subfamily Dorylinae. Not included are species of Ponerinae which have developed legionary behavior independently (see Wilson, E. O., 1958, Evolution 12: 24-31) or the subfamily Leptanillinae, which is very distinct and may be independent in origin. The Dorylinae are not as well developed in the Indo-Australian area as in Africa and the New World tropics. Dorylus itself, which includes the famous driver ants, is centered in Africa and sends only four species into tropical Asia. Of these, the most widespread reaches only to Java and the Celebes. Aenictus, on the other hand, is at least as strongly developed in tropical Asia and New Guinea as it is in Africa, with 34 species being known from the former regions and only about 15 from Africa.

  • The Parasitoid Community of Andricus Quercuscalifornicus and Its Association with Gall Size, Phenology, and Location
    Biodivers Conserv (2011) 20:203–216 DOI 10.1007/s10531-010-9956-0 ORIGINAL PAPER The parasitoid community of Andricus quercuscalifornicus and its association with gall size, phenology, and location Maxwell B. Joseph • Melanie Gentles • Ian S. Pearse Received: 1 June 2010 / Accepted: 18 November 2010 / Published online: 1 December 2010 Ó The Author(s) 2010. This article is published with open access at Springerlink.com Abstract Plant galls are preyed upon by a diverse group of parasitoids and inquilines, which utilize the gall, often at the cost of the gall inducer. This community of insects has been poorly described for most cynipid-induced galls on oaks in North America, despite the diversity of these galls. This study describes the natural history of a common oak apple gall (Andricus quercuscalifornicus [Cynipidae]) and its parasitoid and inquiline commu- nity. We surveyed the abundance and phenology of members of the insect community emerging from 1234 oak apple galls collected in California’s Central Valley and found that composition of the insect community varied with galls of different size, phenology, and location. The gall maker, A. quercuscalifornicus, most often reached maturity in larger galls that developed later in the season. The parasitoid Torymus californicus [Torymidae] was associated with smaller galls, and galls that developed late in the summer. The most common parasitoid, Baryscapus gigas [Eulophidae], was more abundant in galls that developed late in the summer, though the percentage of galls attacked remained constant throughout the season. A lepidopteran inquiline of the gall (Cydia latiferreana [Tortrici- dae] and its hymenopteran parasitoid (Bassus nucicola [Braconidae]) were associated with galls that developed early in the summer.

Abstract 1 The Asian chestnut gall wasp Dryocosmus kuriphilus Yasumatsu (Hymenoptera Cynipidae) is an invasive species in chestnut forests and orchards in many parts of the world. 2 Nuts produced by the European chestnut (Castanea sativa Miller) are important in human food and culture, and as a component in food webs in forest ecosystems. 3 Severe infestations are reported to reduce nut yield, although precise data are lacking because of large natural year-to-year variability in yield. 4 The recent colonization of chestnut orchards in north-eastern Italy, where nut yield has been continuously and precisely recorded for several years, offered an opportunity to calculate the impact of gall wasp infestation level on yield. 5 The nut yield of C. sativa chestnut trees was negatively related to the gall wasp infestation level, with losses as high as 80% being reported when the number of current-year galls was above six galls per 50-cm twig. 6 Yield losses can be explained by direct and indirect factors related to gall formation, and a fuller understanding of the mechanisms involved could identify possible mitigation measures.
