Lattke and published by Univ of California Press. This book was released on 2004-11-04 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ants belonging to the genus Gnamptogenys are important and diverse predators in the forests of the tropics of the Americas, Southeast Asia and Australasia. The recent rapid accumulation of these ants in collections rendered the last revision obsolete, raising the number of known species from about 80 to over a 120 species worldwide. The present study recognizes 49 Old World species, almost half of them new, distributed among 5 species groups. They are present in many entomological collections as the large size of some species and their conspicuousness has caught the attention of even general collectors. They figure increasingly in studies of diversity and ecology due to aspects of their biology such as predatory specialization or their reproduction which includes proper queens in some species and worker reproduction in other species. While most species are ground nesters in forests, some are arboreal and others are subterranean. This revision covers all the Old World species and proposes phylogenetic relations among the different species groups. The identification of the species is possible with aid of well-illustrated keys for workers and queens. The results of working with the keys can be rapidly confirmed by consulting the diagnosis that accompanies each species account, or the full description if need be. The phylogenetic analysis uses a valuable series of internal morphological characters previously unconsidered in ant systematics. Detailed distribution data is also included for each species. This work will be valuable for those studying insect diversity and ecology of forests in Southeast Asia and Australasia. Their diverse biology and relative large size of many species make these ants attractive subjects for comparative studies and this reference should open the door for further studies.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: The ant genus Basiceros is an exclusively Neotropical group known for its cryptic habits. Based on a recent molecular phylogenetic framework, a comprehensive revisionary study of the genus is presented. Nine species are recognized, two of which are described as new (Basiceros browni sp. nov. and Basiceros tumucumaquensis sp. nov.). Basiceros redux (Donisthorpe 1939) is transferred to the genus Octostruma (O. reducta comb. nov.). As part of this revisionary work, taxonomic keys and images to all species and castes are provided. Castes and sexes (including larvae, males, and intercastes) are described for the first time for several Basiceros species. New records considerably expand the distributional range for most species. Natural history data and comments on character plasticity and convergence are also included. Keywords: Attini, systematics, morphology, mouthparts, ant larva, identification, Basiceros-genus group"--Page 3.

This book was released on 2015 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: South American species in the seed-harvester ant genus Pogonomyrmex (subfamily Myrmicinae) are interesting biologically because of their numerous queen phenotypes and life histories. This paper provides a taxonomic revision and reviews the natural history for 21 South American species of Pogonomyrmex so that we can better study their rich and interesting ecology, life history, and evolution. Species treated herein comprise all South American species-groups except for the brevibarbis and rastratus-groups. The following taxa are raised to species: pencosensis Forel 1914 and serpens Santschi 1922. The following new synonomies are proposed: bruchi Forel 1913 is synonomized under coarctatus Mayr 1868 and cunicularius carnivora Santschi 1925 under serpens Santschi 1922. The following new species is described: tinogasta. This paper redescribes workers of all species, and I describe queens and diagnose males for the following species: bispinosus (ergatoid queen, male), inermis (queen, male), laticeps (male), lobatus (queen, male), micans (queen), naegelii(ergatoid queen), pencosensis (ergatoid queen), serpens (ergatoid queen), tinogasta (brachypterous queen), and uruguayensis (queen, male). A neotype was designated for the untraceable or possibly lost type of P. bispinosus, and a holotype or lectotype was designated from syntypes for all other previously described taxa in order to provide a single name-bearing specimen and to facilitate future taxonomic studies. Of the 21 species treated herein, five species have ergatoid (wingless) queens (bispinosus, cunicularius, pencosensis, serpens, mayri), two have brachypterous (short-winged) queens (mendozanus, tinogasta), and two have dimorphic queens (winged and ergatoid in naegelii, brachypterous and ergatoid in laticeps). I also provide keys for workers and queens (in English and Spanish), photographs of all castes, distribution maps, and a summary of known biology.

Download or read book A revision of the ant genus Mystrium in the Malagasy region with description of six new species and remarks on Amblyopone and Stigmatomma Hymenoptera Formicidae Amblyoponinae written by Masashi Yoshimura and published by PenSoft Publishers LTD. 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.

Johnson (Professor) and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: This paper provides a taxonomic revision and a review of the biology for the 10 species of North American seed-harvester ants in the genus Veromessor. Two new synonomies are proposed: V. julianus subsp. clarior W.M. Wheeler and Creighton 1934 new synonym and V. julianus subsp. manni W.M. Wheeler and Creighton 1934 new synonym are synonomized under V. julianus (Pergande, 1894). One new species is described: V. pseudolariversi new species (worker, queen, male), as a result of splitting V. lariversi Smith into two species based on morphological and genetic differences. We also diagnose previously undescribed queens and males for the following species: V. andrei (male), V. chamberlini (queen, male), V. chicoensis (queen, male), V. julianus (queen, male), and V. stoddardi (queen, male). Information on biology of each species is summarized, along with distribution maps and keys to workers, queens, and males. We then discuss the biology for species of Veromessor, focusing on several morphological and ecological traits that display strong variation across the relatively low number of species (10) in the genus. Morphological traits include degree of psammophore development, propodeal spine length, eye size and structure, and worker polymorphism and worker body size, while ecological traits include colony size and foraging method, seasonality of mating flights, mating frequency, and queen size and colony founding strategy.
