Nemoura sp. A

SYNONYMY

LOCALITY: Mongolia: Khovsgol Aimag, Hugin Gol , (N 51.09845°, E 99.32051°; SRP2006070101) .

DIAGNOSIS: The apical prongs of the ventral sclerite of the male epiproct ( Fig. 191, 192) resemble a combination of characteristics possessed by N. sahlbergi ( Fig. 187) and N. arctica ( Fig. 173) Like N. sahlbergi , the prongs are rounded and gradually tapering, but at the tip they are somewhat flattened with a protruding flange about 0.2 mm from the apex ( Fig. 192) which has spines on the lateral margin similar to N. arctica ( Fig. 173). Like N. sahlbergi , the outer (major) lobe of the paraproct is concave ( Fig. 188). In contrast to N. sahlbergi ( Fig. 188) and N. nigrodentata ( Fig. 183), the cercal segments of the male lack any lateral process. The female subgenital plate is broadly rounded but not particularly diagnostic due to variation within the species and similarity to other Nemoura .The nymph is unknown.

DISTRIBUTION—Global: Endemic to Mongolia — Regional: AOB^— Aimag: KhG^.

DISCUSSION: This undescribed species is newly discovered from northern Mongolia. We provide a short diagnosis of it here so that readers know if its distinctness. It will be described fully in a subsequent paper. The male epiproct is notably distinct from N. nigrodentata , another Mongolian endemic, and it was confirmed as a distinct from known Nemoura species through independent examination by Dr. Peter Zwick and Dr. Ignac Sivec.
