Taxonomy, Biogeography and Host Relationships of the Phymatopsallus (Miridae: Phylinae): Contribution to a Planetary Biodiversity Inventory (PBI) presented by Randall T. Schuh Curator and Chair Division of Invertebrate Zoology American Museum of Natural History, New York
Planetary Biodiversity Inventory Project • Support from US National Science Foundation • 5 Year Project • Four projects funded in 2003 • Plant Bugs • Cat Fish • Solanum • Slime Molds • Three projects funded in 2006 • Spiders (Oonopidae) • Scelionidae (Hymenoptera) • Euphorbia
Summary of PBI Project Goals • Orthotylinae and Phylinae: 4000 described species • ~ 75,000 new specimens from field work • ~ 2000 new vouchered host plants • ~ 550,000 specimens in Specimen Database • ~ 20,000 habitus, morphology, host, and habitat images • ~ 1000 new species described • improved classification • Web-based research tools • Systematic Catalog on-line • Specimen database with web-based data entry • 27,000 page Digital Library
Phymatopsallus sensu Knight 1964 simple and flattened setae tubercle on pygophore 1 genus 18 species 3 unequivocal characters marmorate membrane
Phymatopsallus senus novo broader distribution unreversed homoplastic right paramere tubercle on pygophore phallothecal spine marmorate membrane 10 genera 29 species total; 15 new species 9 species-group synonyms 1 unequivocal character
Immediate Outgroup: Schaffneropsallus: Genitalic Structure • Membrane marmorate • Tubercle on pygophore • Vesica with 2 straps • Right paramere lanceolate attenuated • No phallothecal spine
Phymatopsallus group • Membrane marmorate • Tubercle on pygophore present or absent • Vesica with 1 strap • Right paramere truncate, with 2 apical points • 0, 1, or 2 phallothecal spines • Other characters: • color: pale, pink, or green • spots on dorsum present or absent, of variable distribution • left paramere • dorsal margin with or without process • anterior process simple, bifid or cow-horn shaped • posterior process length and curvature • posterior process with break from paramere body or not • vesical spines: present or absent, subapical or medial • form of vestibulum: simple to greatly elongate and elaborate
Phylogenetic Analysis • Parsimony approach using NONA • 127 most parsimonious trees • consistency index = 0.55 • retention index = 0.81 • successive weighting = 1 tree from 127 • Implied Weights using PIWE (method of Goloboff, 1993) • 1 heaviest tree • fit = 210.5 • same tree as successive weighting
Phymatopsallus Group Cladogram No phallothecal spine No tubercle on phygophore No phallothecal spine No tubercle on pygophore nautiloid vestibulum
