Hopperia

The genus has cosmopolitan distribution.^[1]

The genus is a chromadorid nematode of the order Araeolaimida. It is more specifically a member of the family Comesomatidae. The species H. metatypica was originally described as a member of the genus Dorylaimopsis. However several studies have moved it to this genus due to its lateral differentiation consisting of larger, irregularly-distributed coarse dots.^[2][3]
