在分类学上具有重要意义的真皮结节的大小和数量以及颜色上，奥比斯真姬鼠表现出明显的性别差异。雌性的结节比雄性的更大、更多。成熟的雌性是淡绿色，而雄性是暗橙色到红棕色。1967年1月至2月采集的成熟雌虫卵平均直径为2.0 mm。每只雌性平均携带202个卵。最近孵化出的幼虫的存在表明，奥比斯龙虾在2月份产卵。
Eumicrotremus orbis exhibits marked sexual differences in the size and number of the taxonomically important dermal tubercles and in coloration. The tubercles in females are larger and more numerous than those in the males. Mature females are pale green whereas males are dull orange to reddish-brown. Eggs taken from ripe females collected during January and February 1967 averaged 2.0 mm in diameter. Each female carried an average of 202 eggs. The presence of recently hatched juveniles suggests that E. orbis spawns in February.
