(Restionaceae); larval hosts unknown. <b>Remarks.</b> The card on which the type specimen is mounted bears a black letter ‘T’ at the base, a red ‘A’ above it and the number ‘1774’ in red near the apex (Fig. 5). The entry in Blackburn’s catalogue under this number reads: “ <i>Belus tibialis</i> Blackb. W.A. (A) 10-12/[18]86”. It seems that ‘A’ may be a regional code; others in W.A. are ‘P’ and ‘G’. Although this species was evidently described from Western Australia, we have only seen 4 specimens from there (including the holotype), and only two of them recent finds. Barely more have been collected in South Australia, seemingly all at Lucindale, where Lea (1917) recorded it as being “fairly common” nearly a century ago. Three of the Lucindale specimens are labelled as having been collected by [B. A.] Feuerheerdt, who lived in Lucindale at the time and may have collected the other four specimens as well. His name appears in several taxonomic revisions as the collector of others insect specimens taken at Lucindale, though always without a date. A single record from western Victoria has come to light, the specimen collected almost as long ago. All other and recently taken specimens are from a small area in coastal south-eastern Queensland (Fig. 15), which appears to be the only region where the species may still be common. As with <i>S. testaceus</i>, there are no distinct differences between western and eastern Australian specimens, although the aedeagus of the (large, 11.1mm) male from Mt. Dale has a somewhat larger and stouter aedeagus, with a longer tip and the two short, dentate sclerites inside the aedeagal body well separate, not subcontiguous as in specimens from eastern Australia (Lucindale, Cooloola, Tewah Creek).
