Distribution: Type Locality: "Victoria, B. C. (E. M. Anderson); Seattle, Wash. (T. Kincaid); Huachuca Mts., Arizona (Dr. Barnes); and a fifth, doubtful, from Kaslo, B. C. (Dyar)." Description/ Field Marks: Males have antennae filiform (simple). Similar Species: Venusia pearsalli and V. obsoleta may be indistinguishable and if synonymized, pearsalli would have priority. Specimens from the Pacific Northwest identified as obsoleta and pearsalli fall into two BIN groups narrowly separated by DNA barcode. Their true identities appear uncertain. If these two names refer to the same species, one of the BINs might represent a cryptic species without a name. But note, obsoleta was originally described in the genus Nomenia Pearsall, 1905 which was constructed on the basis of antennae structure (unipectinate), not shared by pearsalli (filiform). The original description by Swett and the paratype of obsoleta illustrated in Rep. Prov. Mus. Nat. Hist. (1916), pl. 8, fig. 7., better match V. duodecemlineata, the type species of Nomenia. Pinned specimens of related species. (Hint: select View by Region on the related species page.)
