2. Miridae or Plant Bugs Miridae 10, 000 described species rather delicate asymmetrical, complex male genitalia Orthotylinae & Phylinae > 4, 000 described species focus of PBI several ant mimetic lineages mostly phytophagous often host-specific

6. 20 spp., 45 characters one of two trees Analysis of the Polyozus-group Analysis 17 ingroup species, 3 outgroup species 43 morphological characters NONA/Pee-Wee (hold10000; hold/100; mult*100; jump50;) L=92; Ci=67; Ri=84; concavity: 6: Fit=394.3; 3: Fit=374.8; 1: Fit=337.1 Pee-Wee Polyozus-group supported three distinct clades: Polyozus, Exocarpocoris n. gen., and Ancoraphylus n. gen.

7. 20 spp., 45 characters one of two trees Character support for the Polyozus-group vestiture spicules on dorsal labiate plate anchor-shaped vesica ornament on posterior wall

8. Systematics of Exocarpocoris, n. gen. shape of process U-shaped mark broad vertex and pronotum

9. Systematics of Ancoraphylus, n. gen. tubercle on pygophore left paramere with process on lateral margin right paramere greatly enlarged and subparallel

10. Systematics of Polyozus median process on vesica appendage on dorsal process dorsal process blade-shaped

11. Host Plant Associations 20 spp., 45 characters one of two trees Exocarpos aphyllus (Santalaceae) Acacia spp. (Fabaceae) Jacksonia spp. (Fabaceae) Senna spp. (Fabaceae)

12. Exocarpos aphyllus Exocarpocoris spp. restricted to E. aphyllus E. aurum and E. tantulus sympatric at most localities Distribution of Exocarpocoris spp.

13. Distribution of Ancoraphylus spp. Acacia brachystachya: host of A. auski Acacia aneura: host of A. carolus Acacia stowardii: host of A. mariala

14. male genitalia Distribution of Polyozus spp.

15. P. galbanus Eyles & Schuh described from New Zealand other species of Polyozus-group restricted to Australia Acacia dealbata: host of P. galbanus Acacia dealbata introduced to New Zealand from Australia in the 1870s (Webb 1980) Polyozus galbanus Australian species introduced to New Zealand along with its host Distribution of Polyozus spp.
