Book Description
Volume 161 of Zoologica reviews and analyses the evolution and phylogeny of bees. It is subdivided into two parts Part One: A Preamble to the Evolution and Phylogeny of Bees provides a complete and critical review of all previous attempts to reconstruct the phylogenetic tree of bees (Anthophila / Apiformes) based on morphological, bionomic and molecular approaches and pre- sented in chronological sequence up to and including recent publications. At the same time, the introductory part examines trends in the classification of bees and compares available hypotheses of bee evolution. Part One closes with a family-wise delineation of the fossil history of bees. Part Two: A Phylogenetic Study of Bees in Light of Morphological Evidence adds an experimental study to complement the bibliographical analysis provided in Part One. The phylogenetic relationships of the larger taxonomic units of bees are tested anew using an extensive dataset of selected morphological features. The study uses all common and current computer-aided techniques of cladistic analysis (parsimony, successive/implied weight, Bayesian and neighbor-joining), which are applied to representatives of all seven families, 22 subfamilies and 48 of 58 tribes of bees. The conclusions drawn from this are evaluated for the major groups (i.e., short-tongued and long-tongued bees), and separately for the families, subfamilies and tribes in each case. In a world currently dominated by molecular genetic approaches to phylogeny, this study clearly demonstrates that it is not anachronistic to engage in morphological efforts, because progress can be significantly advanced and the pool of available scientific arguments enriched. The diversity of the object of investigation justifies a variety of methods. This monograph is a much needed reference work of high practical value for all students of bee evolution, phylogeny and morphology. Further, it is ideally suited as good introductory reading material for university level students.

Book Description
The halictid bee tribe Augochlorini is revised at the level of genus and subgenus. Forty-one genera and subgenera are recognized with two being extinct. New subgenera of Augochlora, Electraugochlora, and of Oligochlora, Soliapis, are described for new fossils from Tertiary amber of the Dominican Republic. Complete taxonomic histories are given along with information on revisions at the species level, biological studies, and general distribution for each family- and genus-group taxon. The following subgenera are newly synonymized: Aethechlora new junior subjective synonym of Oxystoglossella, Mycterochlora new junior subjective synonym of Augochlora, Vachalius new junior subjective synonym of Neocorynurella, and Neocorynuroides new junior subjective synonym of Neocorynura. The group Glyptochlora is resurrected from synonymy as a valid subgenus of Augochloropsis. The males of Chlerogella and Micrommation are described for the first time. A key to the genera and subgenera of the tribe is presented along with a key to the species of the rare Augochloropsis (Glyptochlora). Suprageneric relationships in the tribe are explored cladistically. Characters of adult external morphology (72 characters) and ethology (12 characters) are coded for all recognized augochlorine genera as well as outgroups from the Halictini, Nomioidini, and Nomiinae. Results of the cladistic analysis are remarkably resolved but not very robust. The cladogram is summarized and infratribal groups defined. Most notably, the tribe is divided into two monophyletic subtribes: the Corynurina (new subtribe), containing the southern South American genera Corynura, Halictillus, Rhectomia, and Rhinocorynura; and the nominate subtribe, Augochlorina. Implications of the cladistic analysis on diversification in the Augochlorini and evolutionary patterns within the tribe are discussed. New distribution records are given for three species which extend the known ranges of their respective genera. Augochlora essequibensis is a new junior subjective synonym of A. nigrocyanea while A. cladopyga, A. seminigra, Augochlorella bidentata, Halictus caucasicus, H. cerasis, H. chrysaspis, H. myrrhites, H. simotes, and Pereirapis rhizophila are all new junior subjective synonyms of P. semiaurata. Megalopta intermedia, Augochlora nitidior, Augochlorella eusticta, Augochlorodes clementis, and Augochloropsis scabriceps are all recognized as nomina nuda. Vachalius cosmetor, from Colombia and Venezuela, is transferred to Neocorynurella while Corynura biciliata, from Costa Rica, is recognized as a species of Halictini and is transferred to the genus Lasioglossum (Evylaeus) (new combinations). Four fossil and recent species new to science are described as Augochlora (Electraugochlora) leptoloba (fossil), Augochlora (Oxystoglossella) rightmyerae (extant), Oligochlora (Soliapis) rozeni (fossil), and Pseudaugoehlora pulchra (extant).
