Nemurella

DIAGNOSIS: Adult coloration is typically dark to golden brown in life and when preserved. Male are most readily distinguished by the cerci which form a triangle around the genitalic structures ( Fig. 165). Also, the paraprocts ( Fig. 166) are diagnostic, being divided into two long, thin lobes extending past the cercal bases. The inner lobes also surpass the entire length of the cercal segment, in stark constrast to the short and stubby lobes in Nemoura and the wider lobes of Amphinemura . As in Amphinemura , the hypoproct (ventral) extends between the paraprocts. The epiproct is bifurcate from the lateral view. Female subgenital plate is composed of two sclerotized vaginal lobes separated by a depressed median area. Sternum 7 forms a slightly sclerotized lobe that extends posteriorly to partially cover the median depression of sternum 8 ( Fig. 167). Nymphs are generally less pilous than other Nemouridae , but have four thick, stout hairs on abdominal tergites ( Fig. 149), two of which are much longer than all other hairs present along the tergite margin. The hind femur has a transverse row of hairs that are often longer than the femur width. In later instars, the first and third tarsal segments of the hind leg are equal in length ( Fig. 148) and the male paraprocts are readily apparent and curve up between the cerci. In earlier instars, the cerci are as long as the body and the antennae have long hairs on the basal segments.
