59a0629.1 – 1687   Monochroa plutella (Chambers, 1874)

Charles Melton [T] - Locality: AZ
Distribution: Syntype: Texas, probably Waco (USNM).
Field Marks:
There are 4 BIN groups at BOLD (BOLD:AAM8607, BOLD:AAG5281, BOLD:AAG5281, BOLD:ADR2638) relating to this species, all in the same branch of the barcode tree. DNA barcode separates all by over 2.5% inferring the possibility of at least four good species. Those in BOLD:ABW6361 (Arizona) seem to match Megacraspedus exilis Walsingham, 1909 (TL: Guerrero, Mexico). Pending further clarification, all are treated here as plutella.
Similar Species:
  • Megacraspedus exilis Walsingham, 1909.
  • Pinned specimens of related species. (Hint: select View by Region on the related species page.)
Synonymy: Neda plutella Chambers, 1874
Taxonomic Notes: Monochroa plutella (Chambers, 1874), n. comb., was formerly in the genus Megacraspedus (Lee & Landry in Pohl & Nanz (eds.) 2023). USNM specimens of plutella have been misplaced and the true identity cannot at present be verified (Sangmi Lee, pers. comm., 2024).
