A new caridean shrimp, Alvinocaris costaricensis, is described from methane seeps in the eastern Pacific off Costa Rica. The new species is the 16th described species of the genus, and by molecular analysis appears closest to Alvinocaris komaii from the Lau Basin, southwestern Pacific, but shares certain morphological characters with A. lusca from the Galapagos Rift and A. muricola from the West Florida Escarpment, as well as with A. kexueae from the Manus Basin in the Southwest Pacific.
一种新的铠甲虾，哥斯达黎加阿尔文铠甲虾（Alvinocaris costaricensis），是从哥斯达黎加东太平洋的甲烷冷泉中发现并描述的。该新物种是该属中第16个被描述的物种，通过分子分析，它似乎与来自西南太平洋劳盆地的小间阿尔文铠甲虾（Alvinocaris komaii）关系最为密切，但与来自加拉帕戈斯裂谷的卢斯卡阿尔文铠甲虾（A. lusca）、西佛罗里达海崖的鼠穴阿尔文铠甲虾（A. muricola）以及西南太平洋马努斯盆地的科学阿尔文铠甲虾（A. kexueae）具有某些共同的形态特征。
