Resumo: | Two new species of infaunal decapod crustaceans are described based on material collected in Bahía Málaga, Pacific coast of Colombia, in 2009. The mud-shrimp Axianassa darrylfelderi sp. nov. (Axianassidae) appears to be most closely related to A. australis Rodrigues & Shimizu, 1992, A. canalis Kensley & Heard, 1990, and A. jamaicensis Kensley & Heard, 1990. The new species may be distinguished from each of them by a combination of morphological features, mainly on the uropodal exopod, antennal acicle, third maxilliped and first pleonite. The shrimp Leptalpheus canterakintzi sp. nov. (Alpheidae), associated with burrows of A. darrylfelderi sp. nov., undoubtedly represents the eastern Pacific sister species of the western Atlantic L. axianassae Dworschak & Coelho, 1999, which lives exclusively in burrows of A. australis. The two species are reliably distinguishable only by the proportions of the merus and propodus of the third pereiopod. Leptalpheus azuero Anker, 2011, previously known only from the Pacific coast of Panama, is reported for the first time from Bahía Málaga, Colombia. |

O presente estudo descreve duas novas espécies de crustáceos decápodos da infauna baseado em material coletado na Bahía Málaga, costa pacífica da Colombia, em 2009. A primeira delas, o corrupto Axianassa darrylfelderi sp. nov. (Axianassidae), aparenta estar mais relacionada morfologicamente a A. australis Rodrigues & Shimizu, 1992, A. canalis Kensley & Heard, 1990, e A. jamaicensis Kensley & Heard, 1990. Contudo, a nova espécie difere em uma combinação de caracteres morfológicos, principalmente no exópodo uropodial, acículo (escama) antenal, terceiro maxilípede e primeiro pleonito. A segunda espécie nova, o camarão Leptalpheus canterakintzi sp. nov. (Alpheidae), associado às galerias de A. darrylfelderi sp. nov., incontestavelmente representa a espécie-irmã no Pacífico Oriental da espécie L. axianassae Dworschak & Coelho, 1999 do Atlântico Ocidental, a qual vive exclusivamente em galerias de A. australis. As duas espécies são distinguíveis apenas pelas proporções do mero e propodo do terceiro par de pereiópodos. Além disso, Leptalpheus azuero Anker, 2011, previamente conhecido somente para o Panamá, é registrado pela primeira vez para a Colômbia.
