Abstract

Galatheatukitukimea sp. nov. is described from the seamounts near Rapa Nui (Easter Island) and represents the first record of the genus for this region of the Pacific Ocean and for Chilean territory. The new species belongs to the group of species having the carapace with median protogastric and cardiac spines. G.tukitukimea has always been observed associated with the sea urchin Stereocidarisnascaensis. This potential mimicry-based association is uncommon in squat lobsters, which warrants further study.

A来自复活节岛地区（东南太平洋洋脊）海底山的加拉鱼新种（十足目，加拉鱼科），与海胆有亲缘关系。

Galatheatukitukimea sp. nov.来自Rapa Nui（复活节岛）附近的海底山脉，是该属在太平洋地区和智利领土上的首次记录。新种属于甲壳中有中间原胃棘和心棘的种群。tukitukimea一直被观察到与Stereocidarisnascaensis海胆有关。这种潜在的基于模仿的联系在矮胖龙虾中并不常见，值得进一步研究。
