Grotea ambarosasp. nov. is described, illustrated and compared to currently described species of the genus. The new species is characterized mainly by having the mesosoma 2.9× as long as high; genal projection distinct and apically subquadrate; pleural carina distinct only anteriorly to anterior transverse carina; mesosoma almost entirely amber-orange and legs with complex dark brown and white marks. This is the first record of any labenine species for the Greater Antilles; the few distribution records elsewhere in the Caribbean Islands are reviewed and discussed in the context of the biogeography of Labeninae.

Grotea ambarosasp。十一月 描述，说明并与目前描述的属进行比较。该新物种的特征主要在于其间质瘤的长倍高为2.9倍。总体投射明显且顶近于中等；胸膜隆突仅在前横突隆起之前分开；中肌瘤几乎完全是琥珀橙色，腿上有复杂的深棕色和白色痕迹。这是大安的列斯群岛所有唇形花类物种的首次记录；在拉贝尼纳（Labeninae）生物地理学的背景下，对加勒比群岛其他地方的一些分布记录进行了回顾和讨论。
