  • Newly Discovered Sister Lineage Sheds Light on Early Ant Evolution
    Newly discovered sister lineage sheds light on early ant evolution Christian Rabeling†‡§, Jeremy M. Brown†¶, and Manfred Verhaagh‡ †Section of Integrative Biology, and ¶Center for Computational Biology and Bioinformatics, University of Texas, 1 University Station C0930, Austin, TX 78712; and ‡Staatliches Museum fu¨r Naturkunde Karlsruhe, Erbprinzenstr. 13, D-76133 Karlsruhe, Germany Edited by Bert Ho¨lldobler, Arizona State University, Tempe, AZ, and approved August 4, 2008 (received for review June 27, 2008) Ants are the world’s most conspicuous and important eusocial insects and their diversity, abundance, and extreme behavioral specializations make them a model system for several disciplines within the biological sciences. Here, we report the discovery of a new ant that appears to represent the sister lineage to all extant ants (Hymenoptera: Formicidae). The phylogenetic position of this cryptic predator from the soils of the Amazon rainforest was inferred from several nuclear genes, sequenced from a single leg. Martialis heureka (gen. et sp. nov.) also constitutes the sole representative of a new, morphologically distinct subfamily of ants, the Martialinae (subfam. nov.). Our analyses have reduced the likelihood of long-branch attraction artifacts that have trou- bled previous phylogenetic studies of early-diverging ants and therefore solidify the emerging view that the most basal extant ant lineages are cryptic, hypogaeic foragers. On the basis of morpho- logical and phylogenetic evidence we suggest that these special- EVOLUTION ized subterranean predators are the sole surviving representatives of a highly divergent lineage that arose near the dawn of ant diversification and have persisted in ecologically stable environ- ments like tropical soils over great spans of time.

Nguyen, & Katsuyuki Eguchi Abstract The monotypic genus Opamyrma Yamane, Bui & Eguchi, 2008 (Hymeno ptera, Formicidae, Leptanillinae) is an ex- tremely rare relictual lineage of apparently subterranean ants, so far known only from a few specimens of the worker and queen from Ha Tinh in Vietnam and Hainan in China. The phylogenetic position of the genus had been uncertain until recent molecular phylogenetic studies strongly supported the genus to be the most basal lineage in the cryptic subterranean subfamily Leptanillinae. In the present study, we examine the morphology of the worker, queen, male, and larva of the only species in the genus, Opamyrma hungvuong Yamane, Bui & Eguchi, 2008, based on colonies newly collected from Guangxi in China and Son La in Vietnam, and provide descriptions and illustrations of the male, larva, and some body parts of the worker and queen (including mouthparts, tentorium, and sting apparatus) for the first time. The novel morphological data, particularly from the male, larva, and sting apparatus, support the current phylogenetic position of the genus as the most basal leptanilline lineage. Moreover, we suggest that the loss of lancet valves in the fully functional sting apparatus with accompanying shift of the venom ejecting mechanism may be a non-homoplastic synapomorphy for the Leptanillinae within the Formicidae.

Queens are apterous and dichthadiigynes. Males have wings and eyes. Their lifestyles remain virtually unknown. The Western Mediterranean region hosts a high diversity, with 9 species in north Africa and 5 in the Iberian Peninsula. Recent sampling in Central Spain (Tortuero, Guadalajara province) led to the discovery of a colony of a large-sized Leptanilla species. This population can be assigned to L. plutonia, a species known from a single worker (the holotype) until now, easily distinguished from other Iberian species by its large size. These specimens allowed for a redescription of the species, also giving the first insights into its intraspecific variability and morphological structures not mentioned in the original description, such as the presence of a secondary labrum, large apodemes in the postpetiole or a promesosternal keel, among others.

The colonies of many army 15 ant species undergo stereotypical behavioral and reproductive cycles, alternating between brood care 16 and reproductive phases. In the brood care phase, colonies contain a cohort of larvae that are 17 synchronized in their development and have to be fed. In the reproductive phase larvae are absent and 18 oviposition takes place. Despite these colony cycles being a striking feature of army ant biology, their 19 adaptive significance is unclear.

Griebenow 4 Abstract 5 Although molecular data have proven indispensable in confidently resolving the phylogeny of 6 many clades across the tree of life, these data may be inaccessible for certain taxa. The resolution 7 of taxonomy in the ant subfamily Leptanillinae is made problematic by the absence of DNA 8 sequence data for leptanilline taxa that are known only from male specimens, including the 9 monotypic genus Phaulomyrma Wheeler & Wheeler. Focusing upon the considerable diversity 10 of undescribed male leptanilline morphospecies, the phylogeny of 38 putative morphospecies 11 sampled from across the Leptanillinae, plus an outgroup, is inferred from 11 nuclear loci and 41 12 discrete male morphological characters using a Bayesian total-evidence framework, with 13 Phaulomyrma represented by morphological data only. Based upon the results of this analysis 14 Phaulomyrma is synonymized with Leptanilla Emery, and male-based diagnoses for Leptanilla 15 that are grounded in phylogeny are provided, under both broad and narrow circumscriptions of 16 that genus. This demonstrates the potential utility of a total-evidence approach in inferring the 17 phylogeny of rare extant taxa for which molecular data are unavailable and begins a long- 18 overdue systematic revision of the Leptanillinae that is focused on male material.

  • The Internal Phylogeny of Ants (Hymenoptera: Formicidae)
    Systemutic Entomology (1992) 17, 301-329 The internal phylogeny of ants (Hymenoptera: Formicidae) CESARE BARON1 URBANI, BARRY BOLTON” and PH 1 LIP s . WA RDt Zoological Institute of the University, Rheinsprung 9, CH-4051 Basel, Switzerland, *Department of Entomology, The Natural History Museum, Cromwell Road, London SW7 5BD, U.K., and ‘Department of Entomology, University of California, Davis, California 95616, U.S.A. Abstract. The higher phylogeny of the Formicidae was analysed using 68 characters and 19 taxa: the 14 currently recognized ant subfamilies plus 5 po- tentially critical infrasubfamilial taxa. The results justified the recognition of 3 additional subfamilies: Aenictogitoninae Ashmead (new status), Apomyrminae Dlussky & Fedoseeva (new status), and Leptanilloidinae Bolton (new subfamily). A second analysis on these better delimited 17 subfamilies resulted in 24 equally most parsimonious trees. All trees showed a basal division of extant Formicidae into two groups, the first containing (Myrmicinae, Pseudomyrmecinae, Notho- mynneciinae, Myrmeciinae, Formicinae, Dolichoderinae, Aneuretinae) and the second the remaining subfamilies. Clades appearing within these groups included the Cerapachyinae plus ‘army ants’, the Nothomyrmeciinae plus Myrmeciinae, the ‘formicoid’ subfamilies (Aneuretinae + Dolichoderinae + Formicinae), and the Old World army ants (Aenictinae + Aenictogitoninae + Doryline), but relationships within the last two groups were not resolved, and the relative positions of the Apomyrminae, Leptanillinae and Ponennae re- mained ambiguous. Moreover, a bootstrap analysis produced a consensus tree in which all branches were represented in proportions much lower than 95%. A reconstruction of the ground plan of the Formicidae indicated that the most specialized of all recent ants are the members of the subfamily Dorylinae and the least specialized ones are the monotypic Apomyrminae.

    STINGS OF ANTS OF THE LEPTANILLINAE (HYMENOPTERA: FORMICIDAE) BY CHARLES KUGLER Biology Department Radford University Radford, VA 24142 INTRODUCTION Leptanilla is a rarely collected genus of tiny, subterranean ants that probably specialize on geophilomorpti centipedes (Masuko 1990). Because queens are dichthadiiform as in army ants of the Ecitoninae and Dorylinae, the Leptanillinae (Leptanilla plus some male-based genera) have often been considered relatives of those subfamilies (taxonomic history in Wheeler and Wheeler 1965). Masuko (1990) has shown that Leptanilla japonica has some legionary behaviors. Now, however, the subfamily is not uniformly legionary after Bolton (1990a) added the new genera Anom- alomyrma, Protanilla, and transferred in Apomyrma from the ponerine tribe Amblyoponini. With those additions, Bolton (1990a) initially proposed that leptanillines are the sister-group of the ponerines, but subsequent analysis made him revive the hypothesis that leptanillines are the sister-group of the doryline section (Bolton, 1990b). In this paper I test these alternative hypotheses using a previ- ously unexplored character system, the sting apparatus. The sting apparatus, pygidium and hypopygium were dissected from repre- sentatives of the three leptanilline tribes: Leptanillini (Leptanilla), Apomyrmini (Apomyrma) and Anomalomyrmini (Protanilla). Workers and queen of Leptanilla are compared. Phylogenetic 1This paper is dedicated to William L. Brown, Jr., to whom owe a great debt of gratitude for serving as my thesis advisor and mentor.

The rare ant genus Leptanilla was discovered in Macau SAR, China for the first time, which represents the second record for this genus in southeastern China. Through the detailed examination, the new species Leptanilla macauensis sp. nov. described here has unique character conditions particularly in the structure of the clypeus and subpetiolar process. Moreover, the discovery of L. macauensis sp. nov. within an island of vegetation surrounded by a dense urbanized matrix illustrates future possibilities for the discovery of new species in South East Asia, including within heavily disturbed environments.
