Amphinemura

DIAGNOSIS: In life, adult coloration is dark brown over the entire body with dull gray wings ( Fig. 152), often fading to light golden brown in alcohol preservation ( Fig. 159). The epiproct is more elongate and held farther off the abdomen ( Fig. 156) than found in Nemoura , though the shape is variable from species to species. Paraprocts of the male are divided into three lobes, as opposed to Nemoura and Nemurella which have two. The middle lobe, which is the longest, is subequal to and about half the width of the cercal segments, whereas in Nemurella the longest lobe is significantly longer than the cercal segment and very slender. Sternum 8 of the female is well sclerotized and a second process on sternum 7 is parabolic and slightly overlaps sternum 8 ( Fig. 157). The nymphs are densely pilous, with especially long hairs along the entire pronotal margin. Nymphs have four long 5-branched cervical gills, whereas no other genera from Mongolia have gills of any sort although other genera may have gilllike nubs on the lateral margins of the cervical sclerites. Gill remnants occur variably in adults, some species retain filamentous extensions while others only exhibit stubs indicating location of gill insertion.
