SOUTHERN LEPIDOPTERISTS’ NEWS VOLUME 42 NO.3 (2020), PG. 1 PSEUDOTHYRIS SEPULCHRALIS (BOISDUVAL, 1832) (LEPIDOPTERA: THYRIDIDAE) IN LOUISIANA BY VERNON ANTOINE BROU JR., RICKY PATTERSON, AND ROYAL TYLER XPseudothyris sepulchralis (Boisduval) (Fig. 1) was transferred from the Xgenus Thyris to the genus Pseudothyris, gen. n., in Thiele (1986). Thiele Xprovided quite an extensive discussion regarding the historical Xevolutionary taxonomical changes involving several iterations of the names Xof family, genera and species involved (e.g. Thyrididae, Thyridae,Thyris, Xmaculata, sepulchralis and others). XHeppner (2003) listed the range of sepulchralis to include Maine to XFlorida and Illinois to Texas and the months of capture for adults in Florida Xto include March-April. Heppner listed the larval foodplants of Xsepulchralis to include species of the genus Smilax Linnaeus. Earlier XCovell (1984) listed the larval foodplants for sepulchralis to include XClematis Linnaeus, and grapes. Thiele (1986) stated species of Thyris are Xinvariably leaf rollers on soft-leaved Clematis species. Thiele (1997) Xrevised and stated previous hostplant records for sepulchralis feeding on XClematis (Ranunculaceae) and Vitis (Vitaceae) are shown to be in error. In Louisiana, sepulchralis is both diurnal and nocturnal in its adult activities and is univoltine, peaking during the first week of April, records existing from mid-March with stragglers into mid-May (Fig. 2). The Louisiana parish records currently in our possession are illustrated in Fig. 3.
