Genera

see text

The subfamily Euraphiinae was erected by Newman & Ross[1]36 to formalize the "Group of Chthamalus hembeli of Nilsson-Cantell.[2]:275 As originally used in Newman & Ross, it comprised the genera Euraphia and Octomeris. In 1996, Poltarukha[3] revised the subfamily Notochthamalinaea, and removed Octomeris to that position. In 1997[4] and 2000,[5] he revised the Euraphiinae. There have been no further revisions.

Definition and Discussion

Euraphine barnacles have a shell wall of 6 plates, with membraneous basis, rarely calcareous. Plate sutures are often coarsely serrated. In contrast to most other chthamalids, the scutum is higher than wide. The mandible is tridentate, and caudal appendages are usually lacking.

Included genera (4)

  • Euraphia Conrad, 1837, type genus
  • Microeuraphia Poltarukha, 1997
  • Pseudoeuraphia Poltarukha, 2000a
  • Caudoeuraphia Poltarukha, 1997

Habitat and Geographic Distribution

The subfamily is found circumtropically in the littoral and upper littoral zones.[6]:88
