Recognized species

There are two species currently assigned to this genus

Balduza bufo (Van Duzee, 1923) – USA: AZ; Mexico (Baja California, Baja California Sur, Sonora; Cerralvo [Jacques Cousteau] Island, Tiburón Island)
= Hysteropterum bufo Van Duzee, 1923: 192.
= Kathleenum bufo (Van Duzee, 1923); comb. by Gnezdilov, 2004: 2.

Balduza una (Ball, 1910) – USA: AZ, CA, CO, NM, NV, TX; Mexico (Durango, Nuevo León)
= Hysteropterum unum Ball, 1910: 43
= Balduza una (Ball, 1910); comb. by Gnezdilov & O’Brien 2006b: 221.

Economic Importance

Limited.

Plant associations

Balduza bufo – Lycium (desert-thorn, Solanaceae)
Balduza una – Ericameria nauseosa (Pall. ex Pursh) G.L. Nesom & Baird (rubber rabbitbrush, Asteraceae; as Chrysothamnus nauseosus)

Hosts from Wilson et al. 1994; plant names from USDA PLANTS or Tropicos.

Recognition

Hind wings absent or rudimentary, Body elongate (not rounded in dorsal view, vs Paralixes & Traxus), wings not strongly reticulate; Intermediate carinae of the frons present, raised; smaller species usually 4.4 mm or less; vertex not as deeply emarginate as Tylanira; intermediate carinae of frons converging dorsally; frons at the dorsal margin about as wide as tall at median carina (about 1.05x) with dorsal margin v-shaped; vertex about 2x wider than long in middle; Forewings patterned, irregularly speckled; dorso-anterior portion of head raised in lateral view; dorsal margin of forewing concave in lateral view; southwestern (not southeastern)

Here are the couplets in Doering 1938 that separate the 2 species (at the time part of Hysteropterum)
