“…Our findings are similar to the wasp social parasite, Polistes sulcifer, which was found to invade larger and more developed host colonies , and also provide an explanation for the previous observations of allodapine social parasites, I. schwarzi (Smith and Schwarz 2006a) and Braunsapis hewitti (Reyes and Michener 1990), being in the larger, and possibly older, host colonies. The larger host colonies would be beneficial for a social parasite because such colonies would contain a larger amount of resources to exploit.…”

“…Alternatively, the inquilines, such as the genus Inquilina (Michener 1961), exhibit an extremely modified morphology, including lack of scopae, greatly reduced mouthparts, and peculiar head projections (Michener 1970), meaning that social parasitism is obligatory for these species. Twenty-eight allodapine parasitic species have been described, but there have only been a few studies focusing on the nesting biology of some of these species (Michener 1963(Michener , 1965(Michener , 1971Reyes and Michener 1990;Batra et al 1993;Smith and Schwarz 2006a, b).…”

Many factors contribute to the success of a socially parasitic strategy, especially the ability of the parasite to invade a host colony. However, little research has focused on the choices that may be made by an invading parasite, specifically whether parasites actively discriminate between different host colonies and if they have a preference for colonies of a particular size. When an allodapine social parasite, Inquilina schwarzi, was presented with colonies of their host species, Exoneura robusta, the parasites were found to invade the larger host colonies. However, it could not be ascertained from this study whether the parasites were making an active decision concerning which colony to invade, or whether they were simply more attracted to the larger colonies due to potentially stronger odour cues. Regardless of the cause, the larger host colonies are more at risk of being invaded by a social parasite, which would give parasites greater resources for exploitation and could also provide selection against the large host colony sizes.

“…Both hosts and parasites reproduce, but host eggs produced after infiltration of the parasite do not reach adulthood ( Küpper & Schwammberger 1995), and levels of aggression between host and parasite appear related to the extent of host offspring production ( Fisher 1987). In allodapine bees, host and parasite coexist as well ( Reyes & Michener 1990), and parasites functionally replace the host queen in egg production ( Batra et al . 1993 ), as in Psithyrus .…”

“…Such a pattern also applies to parasitic allodapine bees ( Reyes & Schwarz 1999 ) in that Inquilina arises from within Exoneura , its host. However, socially parasitic species have also arisen multiple times within Braunsapis , Allodape , Allodapula and Macrogalea , from closely related non‐parasitic forms ( Michener 1974; Reyes & Michener 1990; Batra et al . 1993 ).…”

Phylogeny of the bee genus Lasioglossum (Hymenoptera: Halictidae) based on mitochondrial COI sequence data

Summary The bee genus Lasioglossum Curtis is a model taxon for studying the evolutionary origins of and reversals in eusociality. This paper presents a phylogenetic analysis of Lasioglossum species and subgenera based on a data set consisting of 1240 bp of the mitochondrial cytochrome oxidase I (COI) gene for seventy‐seven taxa (sixty‐six ingroup and eleven outgroup taxa). Maximum parsimony was used to analyse the data set (using paup*4.0) by a variety of weighting methods, including equal weights, a priori weighting and a posteriori weighting. All methods yielded roughly congruent results. Michener’s Hemihalictus series was found to be monophyletic in all analyses but one, while his Lasioglossum series formed a basal, paraphyletic assemblage in all analyses but one. Chilalictus was consistently found to be a basal taxon of Lasioglossum sensu lato and Lasioglossum sensu stricto was found to be monophyletic. Within the Hemihalictus series, major lineages included Dialictus + Paralictus, the acarinate Evylaeus + Hemihalictus + Sudila and the carinate Evylaeus + Sphecodogastra. Relationships within the Hemihalictus series were highly stable to altered weighting schemes, while relationships among the basal subgenera in the Lasioglossum series (Lasioglossum s.s., Chilalictus, Parasphecodes and Ctenonomia) were unclear. The social parasite of Dialictus, Paralictus, is consistently and unambiguously placed well within Dialictus, thus rendering Dialictus paraphyletic. The implications of this for understanding the origins of social parasitism are discussed.

“…Over 125 species are presently known from Africa, including Madagascar, and these represent eight genera, depending on the classification adopted (Michener, 2007). The largest genus in Africa, and indeed the largest in the tribe, is Braunsapis, a group with varied biologies including frequent social behavior and even social parasitism (Michener, 1970(Michener, , 1971(Michener, , 2007Reyes & Michener, 1990;Aenmay et al, 2006). …”

Abstract.A new species of the allodapine bee genus Braunsapis Michener (Allodapini: Allodapina) is described and figured from a series of females collected in the Central African Republic. Braunsapis maxschwarzi Engel, new species, is similar to B. paradoxa (Strand) from South Africa, both species sharing the concave dorsal surface of the sixth metasomal tergum and the peculiar bifid apical projection of the sixth metasomal sternum. The new species, however, can be distinguished by the more extensively developed yellow markings of the face, the yellow pronotal lobe, the more shoulder-like posterolateral margins of the sixth tergum [more similar in this regard to B. angolensis (Cockerell) and not greatly produced as in B. paradoxa], and the more erect and prominent dorsal setae of metasomal terga IV-VI, among other traits. INTRODUCTIONThe bee tribe Allodapini, although distributed widely in the Old World, is most diverse throughout Africa (Michener, 1975(Michener, , 2007. The Asian fauna, excluding the Near East and Arabia, is solely comprised of species in the genus Braunsapis Michener, and the latter regions add to this a few species of the genera Exoneuridia Cockerell and Compsomelissa Alfken (Michener, 2007;Engel & Dathe, 2011; Engel et al., in press). Australia has a rather robust fauna of nearly 100 species and representatives of five currently recognized genera (Michener, 2007). It is within the African continent, however, that the largest number of species is documented and where the known fauna is most likely to grow with intensive sampling across the equatorial regions. Over 125 species are presently known from Africa, including Madagascar, and these represent eight genera, depending on the classification adopted (Michener, 2007). The largest genus in Africa, and indeed the largest in the tribe, is Braunsapis, a group with varied biologies including frequent social behavior and even social parasitism (Michener, 1970(Michener, , 1971(Michener, , 2007Reyes & Michener, 1990;Aenmay et al., 2006). Journal of Melittology 2No. 21Through the generosity of Maximilian Schwarz, a series of females of a new species of Braunsapis from the Central African Republic was brought to my attention (Fig. 1). The species was intended to be described by the late Stephen G. Reyes (1957Reyes ( -2006, but he did not have the opportunity to prepare a description or figures before he passed away. Herein I present the description of this species along with modified key couplets to aid its identification. MATERIAL AND METHODSSpecimen repositories are denoted by the following abbreviations: MSCA, Maximilian Schwarz Collection, Ansfelden, Austria (ultimately to be deposited in the Oberösterreichisches Landesmuseum, Linz), and SEMC, Division of Entomology, University of Kansas Natural History Museum, Lawrence, Kansas, USA. Photomicrographs were prepared using a Canon 7D digital camera attached to an Infinity K-2 long-distance microscope lens. Measurements were taken with an ocular micrometer on an Olympus SZX-12 stereomicroscope and...
