Remarks

Phronimella is morphologically similar to Phronima , but the body is generally more slender, and the pereopods are much more slender and elongate. In addition, uropod 2 is reduced to a small pointed process in females and juvenile males. In adult males uropod 2 is usually present in a reduced form, with a relatively well­developed exopod, but a small, or obsolete endopod. Occasionally adult males have uropod 2 reduced as in females.
