Nemoura

DIAGNOSIS: In life, adults have dark brown bodies with yellow intrasegmental membranes and clear wings with darkly clouded veins The epiprocts of all Mongolian species have the same general shape and scelortization pattern ( Fig. 177), with two curved lateral sclerites nearly converging at the midline and with apical sclerites that gradually narrow and touch at the midline ( Fig. 178). Epiprocts of Nermoura ( Fig. 177) are stouter and held closer to the body than those of Amphinemura . The paraprocts are divided into two lobes ( Fig. 179), with the inner lobe being reduced or hidden by the hypoproct. Both lobes are much shorter than those in Nemurella . Nymphs lack any true gill structures ( Fig. 147), though have what appear to be gill stubs near the lateral cervical sclerites. Various parts of the nymph body exhibit many short, regularly spaced hairs of equal length. This includes those on the pronotum and tergal margins. Other Nemoridae from Mongolia have longer hairs in diagnostic locations on the pronotum and abdomen. Nymphs within the genus have been variably distinguished based on cercal or femora setation, however this varies between taxonomic treatments.

DISTRIBUTION—Global: Holarctic— Regional: AOB, IDB, POB*— Aimag: AR, BO, BR*, BU^, DO*, GA*, KhD, KhE*, KhG, SE, TO, UB, UV*, ZA.

DISCUSSION: The genus Nemoura , and most of the species found in Mongolia, are well studied in Europe. Nymphs and recently emerged adults typically inhabit seeps or springs.
