Identification

See the identification key for Oxyptilini.

See the species accounts in Landry (1987)(1), Landry (1989)(2), and McDunnough (1927)(3) as Pterophorus ontario.

Sphenarches ontario adults have:

a forewing second lobe that is broader with a well developed, curved outer margin, as in Sphenarches anisodactylus, Geina, Capperia, and Oxyptilus, rather than narrow with an acute apex, as in Buckleria, Dejongia, Trichoptilus, and Megalorhipida.
a brown and unmarked abdominal segment four, as in Geina, and unlike in Capperia and Oxyptilus.
a mostly brown metathorax, as in Geina periscelidactylus and G. sheppardi, rather than the metathorax having large, white lateral patches, as in Geina tenuidactylus and G. buscki, or having white lines on the metathorax and and on the mesothorax connecting the white tegulae, as in Sphenarches anisodactylus, Oxyptilus delawaricus, and Capperia.
tawny brown ground color in the wings and abdomen, as in Geina periscleidactylus and G. sheppardi and Oxyptilus delawaricus, unlike the darker, chocolate brown ground color of Geina tenuidactylus, G. buscki, and Capperia.
a dark triangular patch before the cleft base, unlike the dark, transverse line before the cleft base in Geina periscelidactylus and G. sheppardi.
a dark scale tooth well developed in both the costal and dorsal fringes of the hindwing third lobe, as in Geina, and unlike in Sphenarches anisodactylus (dark scale tooth developed mostly in dorsal fringe).
