Descripción
Rhizomes short-creeping; rhizome scales ferrugineous, lustrous, 0.5–2 mm long, densely setose on margin and surfaces; fronds determinate, mostly 25–75 cm long; stipes dark-castaneous to atropurpureous, lustrous, 10–30 cm long, 0.3–0.8 mm diam., 1⁄3–1⁄2 the frond length, with reddish setae 1.5–3 mm long, sometimes glabrescent; blades pinnatisect, linear-lanceolate, 32–45 X 2.5–4(–5.5) cm, abruptly narrowed at base, lacking black clavate fungi; segments 24–44 pairs, 14–30 X 7–10 mm at the dilate base, acute at tips; costae and veins hidden or inconspicuous; hydathodes not producing lime-dots; indument of setae 0.8–2 mm long on rachises and sometimes sparsely on costae and veins abaxially, setae solitary (unpaired) on segment margins, indument also of minute hairs 0.1 mm; sori to ca. 12 pairs per segment, receptacles glabrous; sporangia with 1 or 2 setae 0.2–0.3 mm long on capsules; spores tetrahedral-globose; 2n=74 (Jam).A

Discusión taxonómica
Determinate fronds, solitary (unpaired) setae on segment margins, and long stipes distinguish T. asplenifolia from T. cultrata. Smith (1981) and Mickel and Beitel (1988) cited Michoacán in the range, but we are now unable to confirm this. Specimens cited or determined as this species from Peru (Tryon & Stolze, 1993), Brazil, and Bolivia appear to be mostly, if not entirely, T. chrysleri (Copel.) A. R. Sm.
Terpsichore lehmanniana (Hieron.) A. R. Sm., from Guatemala and Belize to Ecuador, is closely related to T. asplenifolia and differs in the dull (vs. lustrous) rhizome scales that are densely setulose on the surfaces and margins, and the setose blades abaxially.A
