(Figs. 1–11)  
 Adult habitus: General color dark brown to black (Figs. 1, 8). Head mostly dark brown except the occiput paler. Triocellate, anterior ocellus smaller than posterior ones (Figs. 2A, 9A). Antennae and palpi dark brown. Pronotum disc rectangular (length/width = 1/1.4), black laterally and dark brown medially; rugosities present laterally (Figs.2A, 9A). Legs dark brown (Figs. 1, 8). Wings hyaline. Veins and thoracic sterna similar to Isoperla, typical of this subfamily (Figs. 2A, 3A–B).   
 Male: Forewing length 7.2 mm, hindwing length 6.1 mm, body length 8.5 mm. Abdomen dark brown to black and slightly sclerotized. Terga 3-6 with a pair of small yellow spots medially (obscure in some individuals) (Fig. 3C). Terga 8–9 bearing paired patches of sensilla on the posterior margin. Terga 9–10 with a conspicuous pale medial line and dark longitudinal marks between the sensilla basiconica patches. Posterior half of tergum 10 bilobate, tips curved upwards with sensilla basiconica and several thicker and large setae (Figs 4A–D). Vesicle reduced to a dark semicircle on posterior margin of sternum 8 (Fig. 4E–F). Paraprocts developed and sclerotized, apex with a separate hemispheric sclerite with patch of spines (Figs. 5–6). Aedeagus columnar, membranous, covered by fine asperities but lack large sensilla or spines; apex slightly pointed, with a hemispheric transparent area on its tip (Fig. 7).   
 Female: Forewing length 10.7 mm, hindwing length 9.1 mm, body length 10.0 mm. Body coloration similar to male (Figs. 8, 9A). Tergum 10 without sclerotized or special process. Subgenital plate broadly semicircular and sclerotized (length/width = 1/2.8), with an indistinct median notch (Fig. 9B–C).   
 Egg: 191 µm wide, 271 µm long, including 10 µm for collar. Oval, posterior (opercular) pole regularly rounded, wide, sides of egg less arched near collar, narrowing a little towards anterior pole with collar. Chorion uniformly covered with irregular papillae. Collar 44 µm wide at recurved, wavy distal flange, with a few longitudinal crests, base deeply embedded. Anchor fungiform, evenly covered by globular bodies (Fig. 10).   
 Nymph: Unknown.
