Plants 30-35 cm tall. Rhizomes short and erect, black. Frond clustered; stipes 12-14 cm, slender, bases nearly black, mixed with grayish white setae and few spreading multicellular long hairs, distally castaneous brown and with grayish white setae; laminae oblong, 17-22 × 9-12 cm, not tapering at bases, pinnate-pinnatifid, apices acuminate and pinnatifid; pinnae 10-12 pairs, alternate, sessile, proximal pinnae not shortened, 5-6.5 × 1.2-1.6 cm, bases slightly tapering, truncate, symmetrical, pinnatifid and reaching broad wing on both sides of costae, apices acuminate; pinnae 5-8 pairs, approximate, rectangular, 5-7 × ca. 5 mm, apices rounded or rounded-truncate and with 2-4 angles. Veinlets evident, lateral veins simple, 3 or 4 pairs per segment, proximal pair arising from above base of costules. Laminae herbaceous, when dry deep green, abaxially with sparse short setae along costae, adaxially with sparse appressed short hairs, hairs along costal grooves denser; rachises stramineous, with dense short setae. Sori orbicular, 1 or 2 per segment, dorsifixed at slightly high places at middle of lateral veins, in one row on each side of costules; indusia medium-sized, orbicular-reniform, brown, thickly membranous, slightly pubescent, persistent.

● Wet soil at streamsides in forests; ca. 800 m. N Fujian.

Parathelypteris pauciloba is similar to P. angulariloba, but the latter differs in having rhizomes short and erect, stipes throughout with grayish white short setae and mixed few spreading multicellular long acicular hairs, costae with sparse unicellular short setae abaxially, and indusia slightly pubescent.
