Contribution to the knowledge of Australian Hemiptera. No. II. A revision of the subfamily Graphosomatinae (family Pentatomidae)
The members of the subfamily Graphosomatinae are characterized by the scutellum being frequently as long as the abdomen and so broad as to leave only the basal and outer margins of the corium exposed. Kirkaldy did not regard the group as worthy of subfamily status, and placed it as a tenth tribe of the subfamily Pentatominae, the Graphosomini, and pointed out that it is "Principally characterized by the absent or very short frena, but this does not appear to be restrictive. The large scutellum is no more a character for subfamily separation than it is in Eysarcoris or Discocera." Schouteden and Distant regarded the group as worthy of subfamily rank, and in this contribution I intend to regard it as such.
