Haploperla

DIAGNOSIS: A distinct, wide, brown stripe from head to 10th tergum is present in this monotypic genus in Mongolia ( Fig. 115). Alaskaperla and many other Mongolian chloroperlids are similarly striped, but all lack the characteristic dark, central, head marking present on Haploperla . The male epiproct is short, flat, and forming a small triangle ( Fig. 116). Female subgenital plate round and (Zwick 2007) barely protruding ( Fig. 117). Nymphs have similar coloration ( Fig. 118) to the adult. Nymphs are also characterized by unique hair features, with whorls of apical hairs on the cercal segments and long pronotal hairs on the posterior and anterior margins, but lacking or having sparse hairs along the lateral margin of the pronotum.
