This book was released on 2014-03-31 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ant genus Mystrium in the Malagasy region is revised and six new species are described from Madagascar and its surrounding islands. The discovery of the division of females into major and minor forms was the key to solving this omplicated taxonomic puzzle. We found that in some species of Mystrium, major or minor workers develop as reproductives. In Mystrium, morphological comparison among individuals from the same phenotype, not from their reproductive or functional role is important. Here we propose a new taxonomic framework for interesting and mysterious genus. All species are reclassified into three subgroups based on the reproductive function, and innovative pictorial keys to the species for all castes and sexes are developed. The associations between existing names and males are reexamined, and males of eight of the ten Malagasy species are described or redescribed.

Available in PDF, EPUB and Kindle. Book excerpt: Across the Afrotropical and Malagasy regions, ants are one of the most conspicuous and ecologically dominant animal groups. From driver ants to weaver ants, there are over 2,000 species in Africa alone and over 600 in Madagascar. Ants of Africa and Madagascar introduces readers to the fascinating and diverse ant fauna of the Afrotropical and Malagasy regions. Featuring illustrated keys to subfamilies, separate keys to Afrotropical and Malagasy ant genera, and distribution maps, it also describes diagnostic characters, explores ant ecology and natural history, and includes a list of all currently recognized ant species in the regions. This detailed guide is an essential tool for entomologists and myrmecologists working with and learning about this diverse population of Formicidae.

This book was released on 2014 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leptogenys is the most diverse ponerine ant genus in the world; it is widespread throughout tropical and subtropical regions and there are over 200 extant species described. Most species have ergatoid queens, and many have falcate, bowed mandibles and are specialists on isopod prey. Here, the Malagasy Leptogenys are revised with 60 species recognized, of which 40 are newly described, 18 redescribed, and two subspecies raised to species rank and redescribed. Included in the revision are a key to species based on the worker caste, geographic distributions, descriptions of intraspecific variation, and notes on natural history. The following species are redescribed: L. acutirostris Santschi, L. alluaudi Emery, L. angusta (Forel), L. antongilensis Emery, L. arcirostris Santschi, L. coerulescens Emery, L. falcigera Roger, L. gracilis Emery, L. grandidieri Forel, L. incisa Forel, L. maxillosa (F. Smith), L. oswaldi Forel, L. pavesii Emery, L. ridens Forel, L. saussurei (Forel), L. stuhlmanni Mayr, L. truncatirostris Forel, and L. voeltzkowi Forel. The following are raised to species and redescribed: L. imerinensis Forel stat. rev., stat. n.; and L. suarensis Emery stat. rev., stat. n. The following are described as new: L. alamando sp. n., L. alatapia sp. n., L. ambo sp. n., L. andritantely sp. n., L. anjara sp. n., L. avaratra sp. n., L. avo sp. n., L. barimaso sp. n., L. bezanozano sp. n., L. borivava sp. n., L. chrislaini sp. n., L. comajojo sp. n., L. diana sp. n., L. edsoni sp. n., L. fasika sp. n., L. fiandry sp. n., L. fotsivava sp. n., L. johary sp. n., L. lavavava sp. n., L. lohahela sp. n., L. lucida sp. n., L. malama sp. n., L. mangabe sp. n., L. manja sp. n., L. manongarivo sp. n., L. mayotte sp. n., L. namana sp. n., L. namoroka sp. n., L. pilaka sp. n., L. rabebe sp. n., L. rabesoni sp. n., L. ralipra sp. n., L. sahamalaza sp. n., L. tatsimo sp. n., L. toeraniva sp. n., L. tsingy sp. n., L. variabilis sp. n., L.vatovavy sp. n., L. vitsy sp. n., and L. zohy sp. n. Most of these species are endemic to the region. Of the endemic species, two are restricted to the Comoros (L. comajojo, L. mayotte), 52 occur only in Madagascar, and two are shared by both islands (L. fiandry, L. gracilis). Three species in the maxillosa group, considered introduced to the region, are recorded from Madagascar, Comoros, Mauritius, Reunion, and Seychelles. Leptogenys stuhlmanni, the only species in the stuhlmanni group, which was collected and first described from Moheli by Forel in 1907, has not been rediscovered and may have gone locally extinct.

Eighteen members of this group are recognized and described, and an illustrated identification key to this group is also presented. One name is raised to species level: P. decollata Forel, 1892 stat. nov. We also redescribe worker castes and designate lectotypes for P. bessonii Forel, 1891, P. decollata Forel, 1892, P. grallatrix Emery, 1899, P. madecassa Forel, 1892, and P. oswaldi 1891.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: This paper provides a taxonomic revision and reviews natural history for 35 South American species of the seed-harvesting ant genus Pogonomyrmex. Species treated herein mostly comprise the P. rastratus-group; four species are revived from synonomy, three taxa are elevated from subspecies to species, five taxa are synonymized, and 20 new species are described. The following taxa are revived from synonomy: P. intermedia Menozzi, P. semistriata Emery, P. spinolae Emery, and P. weiseri Santschi. The following taxa are raised from subspecies to species: P. leonis Kusnezov, P. pulchellus Santschi, and P. sanmartini Kusnezov. The following new synonymies are proposed, with the senior synonym listed first, and the junior synonym(s) in parentheses: P. carbonarius Mayr (= P. kusnezovi Cuezzo & Claver, = P. weiseri var. neuquensis Santschi, = P. variabilis Santschi); P. vermiculatus Emery (= P. vermiculatus var. chubutensis Forel, = P. vermiculatus var. jorgenseni Forel). The following new species are described: P. apterogenos, P. araucania, P. atacama, P. bolivianus, P. colca, P. cusquena, P. excelsior, P. forelii, P. granulatus, P. lagunabravensis, P. loaensis, P. mapuche, P. maulensis, P. pichachen, P. propinqua, P. santschii, P. strioligaster, P. tafi, P. varicolor, and P. wilsoni. One species treated herein has brachypterous queens (P. atacama), one species has dimorphic queens (winged and brachypterous in P. longibarbis), and two species have ergatoid (permanently wingless) queens and ergatoid males (P. apterogenos, P. laguanbravensis); the latter two are the only known ant species in which both sexual castes are only ergatoid. I also provide keys for workers and queens (in English and Spanish), diagnoses for males, photographs of known castes, distribution maps, and a summary of known biology.

Available in PDF, EPUB and Kindle. Book excerpt: "In this enormously useful book, a profound need is met by a profound contribution, the first such comprehensive work in over fifty years. While brief, Ants of North America is the distillation of a vast amount of study and practice. It is a joy to browse and read, and will have an important impact on the study of ants."—Edward O. Wilson, University Research Professor Emeritus, Harvard University "Two of the most prolific ant faunists have produced a marvelous taxonomic guide to the ant genera of North America. The keys and genus descriptions are succinct and easy to read, the illustrations superb. This book is a must for entomologists, ecologists, and particularly all who study ants."—Bert Hölldobler, Foundation Professor of Life Sciences, Arizona State University "This book represents a bold advance in the study of North American ants. It provides, for the first time, an accessible and lavishly illustrated guide to all the ant genera occurring in the United States and Canada. It will greatly enhance both public interest in ants and scientific investigation of their ecology, behavior and evolution."—Philip S. Ward, Department of Entomology and Center for Population Biology, University of California at Davis
