Preliminary morphological analysis of relationships between the spider wasp subfamilies (Hymenoptera: Pompilidae): revisiting an old problem

No qualitative cladistic analysis has been performed previously for the subfamily classification of Pompilidae (Hymenoptera). In 1994 Shimizu proposed six subfamilies, but their validity and relationships remain inconclusive. The objective of this study was to perform a quantitative analysis of phylogenetic relationships of the Pompilidae, with emphasis on testing the validity of proposed subfamilies. Two cladistic analyses were performed based on morphological evidence. First, a maximum‐parsimony analysis of Shimizus original morphological data matrix (72 taxa by 54 characters) was conducted, with the data subjected to a heuristic search for the first time with phylogenetic software. The resulting strict‐consensus cladogram yielded a monophyletic Ceropalinae that was sister group to a large polytomy containing members of the remaining five subfamilies. In a second analysis, several of Shimizus characters were re‐examined, and new characters and more taxa were added to the data set. Terminal taxa were coded as species rather than as generic abstractions, and 20 additional morphological characters were introduced. The analysis was based on 77 morphological characters derived from the adults of 84 taxa. This second analysis suggested that Notocyphinae sensu Shimizu (1994) was nested within Pompilinae and that Epipompilinae sensu Shimizu (1994) was nested within Ctenocerinae; neither should retain their status as a separate subfamily. Lastly, Chirodamus s.s., which historically has been a member of the Pepsinae, is placed within the Pompilinae with reservations rather than erecting a new subfamily. After these allowances were made, a strict consensus tree gave the following relationships: (Ceropalinae + (Pepsinae + (Ctenocerinae + Pompilinae))).

Invisible Compromises Global Business, Local Ecosystems, and the Commercial Bumble Bee Trade

The purpose of this article is to challenge organizational scholars, management educators, and business leaders to consider more deeply the impact of global business activities on local ecosystems. Drawing on the management, sustainability, and entomology literature, we illustrate the complex relationship between global business and biodiversity loss through the lens of the commercial bumble bee trade. Global firms in this trade rear and supply bees for greenhouse crop pollination. We build on a well-known global strategy framework used in management education by adding a sustainability dimension, and offering propositions for the relationship between global business strategy and the strength of environmental sustainability. We conclude that a locally responsive, place-sensitive business strategy supports the strongest degree of environmental sustainability, and addresses the invisible compromises to ecosystem health that may result from the efforts of global firms to provide otherwise beneficial products and services.

Revision of New World Species of the Cleptoparasitic Pompilid Genus Irenangelus Schulz (Hymenoptera: Pompilidae)

Abstract The New World species of Irenangelus Schulz are revised, with a key to species, re-descriptions, distributional information and illustrations for each species. In addition, two new species, I. evansi and crossopus, are described from Costa Rica and Panama.

Revision of the odd brachycistidine genus Acanthetropis Wasbauer, 1958 (Hymenoptera, Tiphiidae, Brachycistidinae)

Author(s): Kimsey, LS; Wasbauer, MS | Abstract: The species of the brachycistidine genus Acanthetropis are reviewed. A key to the species is provided along with distribution maps. One species, A. normalis Malloch, 1926, is relegated to synonymy under A. ae-qualis (Fox, 1899). Copyright Lynn S. Kimsey, Marius S. Wasbauer.

The Pompilidae of the Algodones Dunes, California, with description of new species (Hymenoptera: Pompilidae)

Abstract The Algodones dunes in southeastern California are among the largest dunes systems in North America comprising roughly 700 km2. Our 2-year inventory of the insects of these dunes has revealed a fauna of more than 1100 species, including more than 60 species new to science. Among these are 21 species of Pompilidae given in a table, including Ageniella (Ageniella) arenicola Wasbauer and Kimsey, sp. nov., and Ageniella (Priophanes) pernia Wasbauer and Kimsey, sp. nov., described herein.

A new species of Priochilus Banks, 1944 (Hymenoptera, Pompilidae, Pompilinae) from Panama

Priochilus chrysopygus Wasbauer, Cambra & Añino sp. nov. based on both sexes is described and illustrated. This new species is related to P. splendidulus (Fabricius). A short synopsis of biology in the genus Priochilus is given.
