Description:
Species Description - Differs from D. expansum by: pinnae with pinnules stalked 4–5 mm; indument abaxially of sparse, brown, linear to lanceolate or narrowly ovate, entire or erose scales 0.5–5 mm long on costae and costules, adaxially the blades glabrous except for minute hairs 0.1 mm long in rachial, costal, and costular grooves; sori with erose indusia 0.3–0.5 mm wide; 2n=328 (Jam).

Stolze et al. (1994) restricted the application of this name to plants from South America, but specimens from Mesoamerica seem conspecific. Specimens determined by Stolze (1981) from Guatemala and elsewhere as D. diplazioides seem mostly to be D. hians. Fink 120 (UC), cited by Palacios-Rios (1992) as this species, is D. expansum. For differences with D. expansum, see discussion under that species.
