Phycitodes reliquellum (Dyar, 1904)
Homoeosoma reliquellum Dyar, 1904
Rotruda mucidella reliquellum Heinrich, 1956:226 (1)
Phycitodes albatella reliquella
Elevated from subsp. of albatella by Neunzig, 1997 (2)
Expanse 15-16 mm - Dyar, 1904:112
"Smooth, obscure cinereous, thickly dusted with white on costal half. Lines obsolete, the inner represented by three black dots, the upper and lower of which are very small, the middle one more outwardly placed; outer line indicated by an outward blackish shade, curved, regular and even. Discal dots black, joined into a large spot in the male, narrowly separated in the female. Hind wings whitish, gray tinted along costa and outer edge. Expanse 15-16 mm... Nearly allied to Homceosoma mucidellum Rag. but smaller, smoother cinereous, the outer line very vague and slightly curved, discal dots approximated or fused..." - Dyar, 1904:112
Eastern North America
Heinrich (1956:226) treated reliquellum and mucidella as subspecies of Rotruda mucidella (Ragonot, 1887). Neunzig (1997) elevated mucidella and reliquellum to species status. Scholtens & Solis (2015)(3) follows Neunzig (1997).
As of 2016, DNA barcoding at BOLD does not seem to be able to differentiate between reliquellum and mucidella. Neunzig (1997) does not appear to explain why he overturned Heinrich (1956). In separating the two species, he mentions distribution and morphological differences which Heinrich apparently considered superficial. Heinrich noted variation in genitalia but found the variations were not confined to particular populations.

Phycitodes mucidella is a western species. It averages larger with forewings more heavily dusted with white and more contrasting black scales. (2)
