Abstract The blind fossil amphipod, Caecorchestia bousfieldi, Hegna and Lazo-Wasem, new genus and species, is described from the lower Miocene Campo La Granja amber mines in Chiapas, Mexico, based on more than 130 specimens in diverse states of preservation. It is the second amphipod species to be described from Chiapas amber. C. bousfieldi belongs to the Talitridae, a family of amphipods that have successfully colonized terrestrial habitats. Exactly how fully terrestrial Caecorchestia bousfieldi was is unclear, and its blindness likely indicates that it occupied a cryptic habitat. A review of the amphipod fossil record is given which demonstrates that the amphipods first appeared as fossils in the Eocene.

用显微CT扫描记录的来自中新世早期恰帕斯琥珀中的一种新化石talitrid片脚类动物

摘要 基于处于不同保存状态的 130 多个标本，描述了来自墨西哥恰帕斯州下中新世 Campo La Granja 琥珀矿的盲端足类化石 Caecorchestia bousfieldi、Hegna 和 Lazo-Wasem，这是新属和种。它是从恰帕斯琥珀中描述的第二个片脚类动物。C. bousfieldi 属于 Talitridae，这是一个已成功在陆地栖息地定居的片脚类动物。陆地上的 Caecorchestia bousfieldi 究竟有多完整尚不清楚，它的失明可能表明它占据了一个神秘的栖息地。对片脚类化石记录的回顾表明，片脚类动物首先在始新世作为化石出现。
