Muellar (WAMP). <b>Comments.</b> <i>Therophilus rugosus</i> exhibits a similar BROW colour pattern to <i>T. tricolor</i>, including the black and white banding pattern on the hind leg. However, <i>T. rugosus</i> can be readily distinguished by the extensive rugose sculpturing of the propodeum compared with only faint sculpturing on <i>T. tricolor</i>. <i>Therophilus rugosus</i> is one of the most abundant and widespread species that is recorded throughout Australia, including Lord Howe Island, from the arid Eyrean to the temperate south-western, Kosciuskan, Tasmanian, tropical/sub-tropical Timorian and Torresian biogeographic regions (Fig. 21A). Known host records (Table 2) include two native pest lepidopteran species, <i>Etiella behrii</i> and <i>Epiphyas postvittana</i>. The holotype is in relatively good condition except both antennae missing all flagellomeres.
