The Magnificent Megaspilidae: Conostigmus spp. (Hymenoptera: Megaspilidae) of the Nearctic Carolyn Trietsch István Mikó Andrew R. Deans The Pennsylvania State University Klopfstein et. al (2013); Vilhelmsen et. al (2010) Morphological Molecular (bootstrap values given) (posterior probabilities given) Ceraphronidae Megaspilidae Lagynodinae Goloboff et. al (2008); Ronquist & Huelsenbeck (2003) Conostigmus Dahlbom 1858 • 169 species worldwide • Little known about: – Hosts: Diptera (Phoridae, Syrphidae) Mecoptera, Hymenoptera, and…? – Ectoparasitoids, but also endoparasitoids? – Behavior? Life history??? Johnson & Musetti (2004) Revision of Nearctic Conostigmus • 32 species in North America (north of Mexico) • Integrated taxonomic approach relying on both traditional and innovative methods Johnson & Musetti (2004) Redescription of C. albovarius Dodd 1915 Trietsch et al.

Specimens for Study • Over 800 Conostigmus specimens from 13 museums and collections Sampling in: AZ, CT, MA, NC, NJ, NY, PA, UT Morphological Approach Different species? C. lucidus n. sp.

Phenotypic Ontologies • All morphological characters (somatic and male genitalia) represented in OWL Manchester Syntax Phenotype RCN Summit at Biosphere 2 facility near Tuscon, AZ, 26-28 February 2016 Phenotype Ontology Research Coordination Network; NSF-DEB-0956049; http://www.phenotypercn.org/ Photo by Andy Deans (CC BY 2.0). Conostigmus Morphology • 39 species concepts (so far!) – 32 species known in Nearctic – New to science? Molecular Approach • Problems with male genitalia characters: – Matching males and females? – Actually separate species? Molecular Approach • Relying on mitochondrial CO1, nuclear 28S, 16S rRNA, and/or ITS rDNA • Very difficult! – No previous Conostigmus CO1 primers Molecular Approach • Designed CO1 primers for Conostigmus, Dendrocerus, and Ceraphron • Will use molecular data to: – Test the species concepts built using morphology – Match male and females Trichosteresis sp. Mikó et. al (in press) Dorsal C. bipunctatus C. sp. 3 Ventral C. sp. C7A C. sp. C7B This presentation is not issued for purposes of zoological nomenclature, and is not published within the meaning of the Code. Confocal Laser Scanning Microscopy (CLSM) Histology • Exploring the felt fields and semitransparent patches using: – Transmission Electron Microscopy (TEM) – Serial block-face scanning electron microscopy (SBFSEM) Serial block-face scanning electron microscopy (SBFSEM) Semitransparent Patch Felt Field Felt Field Semitransparent Patches Future Directions • Continue work on semitransparent patches and felt fields • Finish Nearctic revision of Conostigmus • Investigate higher level phylogeny of Ceraphronoidea • Establish a live colony of megaspilids – Functional morphology of male (and female) genitalia structures – Function of felt fields and semitransparent patches Acknowledgments This talk is available on Figshare at: Thanks to Lubomir Masner, Michael J.
