View 3 PicturesKey features I discerned with a microscope include that the femoral flange is blunt (later note: on nymphs of this size, it's somewhat ambiguous and the femora (Femur: The main segment of an insect's leg close to the body, in between the tibia and the trochanter.) can be damaged in the collection process), the postero-lateral (Lateral: To the side.) spines have a longer anterior (Anterior: Toward the front of an organism's body. The phrase "anterior to" means "in front of."), the first gill is not extended, all gills are tracheated, and the femora (Femur: The main segment of an insect's leg close to the body, in between the tibia and the trochanter.) have a distinctive brown spot on the center while all the other spots are gray.
