The Polyozus-group (Miridae, Phylinae) in Australia: Systematics and host plant associations Christiane Weirauch Division of Invertebrate Zoology, American Museum of Natural History, New York

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

PBI Project Focus: Australia Species of flowering plants 18, 000 known from Australia, 9, 000 from North America Species of Miridae ~ 2, 000 described from North America, ~ 200 species from Australia Schuh & Cassis collecting trips 1995 - 2002 9 species of Phylini in Australia, 5 belong to Campylomma • Depauperate fauna of Miridae? • Sampling bias? % %%%% $$ $$ % # % $% % $$% $%$% # # $$#$$ ##$$$## % # $ %## %%% #% $ $ # # $#$%#$# # $$#% $#$ $ %$ $%% $#$ ## #### $ #$###$#$#$#% % % % %%%% % %%$%% % %%%%%% %% $$ $$ $$$$ $$ $$ $ $ %% % $$ ###### # # ## # %%$$ # %% % %%% ##% # % %%#%#%#% # # ## ##### #$# % # #### #$$###### ### ## ## #

The Polyozus-group `

Analysis of the Polyozus-group Analysis 20 spp. , 45 characters one of two trees 17 ingroup species, 3 outgroup species 43 morphological characters NONA/Pee-Wee (hold 10000; hold/100; mult*100; jump 50; ) Pee-Wee Polyozus-group L=92; Ci=67; Ri=84; concavity: 6: Fit=394. 3; 3: Fit=374. 8; 1: Fit=337. 1 supported three distinct clades: Polyozus, Exocarpocoris n. gen. , and Ancoraphylus n. gen.

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

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

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

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

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

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

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

Distribution of Polyozus spp. male genitalia
