A Casual Cantharophily: the Meeting Between Astylus
Journal of Pollination Ecology, 5(12), 2011, pp 86-89 — Short Communication — A CASUAL CANTHAROPHILY : THE MEETING BETWEEN ASTYLUS VARIEGATUS (C OLEOPTERA : MYLERIDAE ) AND OXYPETALUM BANKSII (A POCYNACEAE : ASCLEPIADOIDEAE ) Milene Faria Vieira* and Rúbia Santos Fonseca Departamento de Biologia Vegetal, Universidade Federal de Viçosa, 36570-000 Viçosa, Minas Gerais, Brazil Abstract —Cantharophily is reported for the first time in a Brazilian asclepiad, involving the mylerid Astylus variegatus and the nectariferous flowers of Oxypetalum banksii , a plant mainly pollinated by wasps. The use of nectar as food by A. variegatus , considered pollinivorous and granivorous, is also novel. The mutual interaction described here is an example of a plant-pollinator interaction with generalist insects visiting a plant with a specialized pollination system. It’s also temporary and occasional and, therefore, is often overlooked in studies of plant-pollinator interactions. In this study, we found that the casual meeting between O. banksii and A. variegatus was a key event for the reproduction of both. Key words: Asclepiad, Atlantic Forest, Brazil, beetles, specialized pollination, wasps The asclepiads (Apocynaceae: Asclepiadoideae, sensu (Asclepias woodii , Sisyranthus trichostomus and Endress & Bruyns 2000) have highly elaborate and Xysmalobium involucratum ) and chafer beetles (Scarabaeidae: complicated flowers. There is an unusual synorganization Cetoniini). Shuttleworth and Johnson (2008) described, also between parts and also between organs of different categories in South Africa, a bimodal pollination system in the asclepiad (Endress 1994). This has led to the evolutionary origin of Xysmalobium undulatum ; its pollination is performed by two new organs that are not present in other angiosperm groups in unrelated species (or functional groups) of pollinators: chafer this combination: corona (more or less well developed beetles and pompilid wasps (Hymenoptera: Pompilidae). -

Phylogeny and Systematics of the Rauvolfioideae
PHYLOGENY AND SYSTEMATICS Andre´ O. Simo˜es,2 Tatyana Livshultz,3 Elena OF THE RAUVOLFIOIDEAE Conti,2 and Mary E. Endress2 (APOCYNACEAE) BASED ON MOLECULAR AND MORPHOLOGICAL EVIDENCE1 ABSTRACT To elucidate deeper relationships within Rauvolfioideae (Apocynaceae), a phylogenetic analysis was conducted using sequences from five DNA regions of the chloroplast genome (matK, rbcL, rpl16 intron, rps16 intron, and 39 trnK intron), as well as morphology. Bayesian and parsimony analyses were performed on sequences from 50 taxa of Rauvolfioideae and 16 taxa from Apocynoideae. Neither subfamily is monophyletic, Rauvolfioideae because it is a grade and Apocynoideae because the subfamilies Periplocoideae, Secamonoideae, and Asclepiadoideae nest within it. In addition, three of the nine currently recognized tribes of Rauvolfioideae (Alstonieae, Melodineae, and Vinceae) are polyphyletic. We discuss morphological characters and identify pervasive homoplasy, particularly among fruit and seed characters previously used to delimit tribes in Rauvolfioideae, as the major source of incongruence between traditional classifications and our phylogenetic results. Based on our phylogeny, simple style-heads, syncarpous ovaries, indehiscent fruits, and winged seeds have evolved in parallel numerous times. A revised classification is offered for the subfamily, its tribes, and inclusive genera. Key words: Apocynaceae, classification, homoplasy, molecular phylogenetics, morphology, Rauvolfioideae, system- atics. During the past decade, phylogenetic studies, (Civeyrel et al., 1998; Civeyrel & Rowe, 2001; Liede especially those employing molecular data, have et al., 2002a, b; Rapini et al., 2003; Meve & Liede, significantly improved our understanding of higher- 2002, 2004; Verhoeven et al., 2003; Liede & Meve, level relationships within Apocynaceae s.l., leading to 2004; Liede-Schumann et al., 2005). the recognition of this family as a strongly supported Despite significant insights gained from studies clade composed of the traditional Apocynaceae s. -

Shuttleworth, S.D. Johnson School of Biological and Conservation Sciences, University of KwaZulu-Natal Pietermaritzburg, Private Bag X01, Scottsville 3209, South Africa Received 1 April 2009; received in revised form 21 July 2009; accepted 27 July 2009 Abstract Studies of pollination in southern African asclepiads (aside from the stapeliads and members of the genus Ceropegia) are remarkably scarce given the diversity of asclepiad species in the region. In this study, we report new observations of insect flower visitors and their pollen loads for 15 species of South African asclepiads in the genera Asclepias, Aspidoglossum, Miraglossum, Pachycarpus, Periglossum, Woodia and Xysmalobium. Nectar properties are also presented for some species. Four specialized pollination systems are suggested by these observations: (1) pollination by wasps in the genus Hemipepsis (Hymenoptera: Pompilidae) in eight species, (2) pollination by chafer beetles (Scarabaeidae: Cetoniinae) in three species, (3) pollination by honeybees, Apis mellifera (Hymenoptera: Apidae) in two species, and (4) pollination by flies from various families in one species. The pollination system of Asclepias crispa remains unclear but appears to be one of generalized insect pollination. Future research is likely to confirm the preponderance of specialized pollination systems within this group of plants in southern Africa. © 2009 SAAB. Published by Elsevier B.V.

We discuss the lifestyle of adult dipterans and the importance of immature stages as saprophages, mycetophages, phytophages and parasites on the examples of selected taxa and their specific adaptations to life and survival in various biotopes, including other living organisms, pointing to both their immense role in the circulation and decomposition of organic matter and the still insufficient knowledge on their ecology, biology and systematics.

The Role of Mating Systems in Sexual Selection in Parasitoid Wasps
Biol. Rev. (2014), pp. 000–000. 1 doi: 10.1111/brv.12126 Beyond sex allocation: the role of mating systems in sexual selection in parasitoid wasps Rebecca A. Boulton∗, Laura A. Collins and David M. Shuker Centre for Biological Diversity, School of Biology, University of St Andrews, Dyers Brae, Greenside place, Fife KY16 9TH, U.K. ABSTRACT Despite the diverse array of mating systems and life histories which characterise the parasitic Hymenoptera, sexual selection and sexual conflict in this taxon have been somewhat overlooked. For instance, parasitoid mating systems have typically been studied in terms of how mating structure affects sex allocation. In the past decade, however, some studies have sought to address sexual selection in the parasitoid wasps more explicitly and found that, despite the lack of obvious secondary sexual traits, sexual selection has the potential to shape a range of aspects of parasitoid reproductive behaviour and ecology. Moreover, various characteristics fundamental to the parasitoid way of life may provide innovative new ways to investigate different processes of sexual selection. The overall aim of this review therefore is to re-examine parasitoid biology with sexual selection in mind, for both parasitoid biologists and also researchers interested in sexual selection and the evolution of mating systems more generally. We will consider aspects of particular relevance that have already been well studied including local mating structure, sex allocation and sperm depletion. We go on to review what we already know about sexual selection in the parasitoid wasps and highlight areas which may prove fruitful for further investigation. In particular, sperm depletion and the costs of inbreeding under chromosomal sex determination provide novel opportunities for testing the role of direct and indirect benefits for the evolution of mate choice.
