Kosrae, Caroline Islands


Describer of species previously given as Lesson and Garnot, but Desmarest was apparently using a manuscript name#R#R. Closely related to D. pacifica, D. aurorae and perhaps D. galeata. Most races based mainly on rather slight differences in size. Five subspecies currently recognized.

Subspecies and Distribution
  • D. o. monacha (Momiyama, 1922) – Palau Is; also Yap (W Caroline Is), where possibly introduced.
  • D. o. teraokai (Momiyama, 1922) – Chuuk (C Caroline Is).
  • D. o. townsendi (Wetmore, 1919) – Pohnpei (E Caroline Is).
  • D. o. oceanica (Desmarest, 1826) – Kosrae (E Caroline Is).
  • D. o. ratakensis (Taka-Tsukasa & Yamashina, 1932) – Wotje, Ailinglaplap, Arno and Jaluit (Marshall Is). Probably extinct in some of the islands.
