             Southern Metarranthis

Distribution: NC to FL and LA, and possibly NJ (Schweitzer et al. 2011).Type locality: "Amérique septentrionale [North America]".
Similar Species:
  • Metarranthis Species 1 (not formally described), "Mid-Atlantic Metarranthis"; NS to NC (Schweitzer et al. 2011).
  • Metarranthis Species 2 (Metarranthis lateritiaria of authors, not Guenée, (Forbes 1948)(Rupert 1943); NS to NC (Schweitzer et al. 2011).
  • Pinned specimens of related species. (Hint: select View by Region on the related species page.)
Synonymy: Endropia lateritiaria Guenée, [1858]
Taxonomic Notes: Metarranthis lateritiaria (Guenée, [1858]): There has been much confusion with this species, pilosaria Packard, and undescribed species; the true identity may still be in question. The type locality was given only as "Amérique septentrionale [North America]" (WS: "42mm"). Forbes (1954) believed it was a northeastern species (WS: ~25-32 mm) following Rupert (1943). Schweitzer et al. (2011) believed it was a southern species and referred to the northern species as "Metarranthis Species 2" (undescribed). They also mention "Mid-Atlantic Metarranthis", "Metarranthis Species 1" (undescribed). James K. Adams (in litt., 2023) reports of a large, pale, early flying, wide spread Metarranthis which may refer to one of the afore mentioned. DNA barcode would seem to support the existence of at least three cryptic species.
