Strelkovimermis spiculatus, Poinar & Camino 1986 (Nematoda: Mermithidae)was found parasitizing some mosquito genera as Aedes (Ochlerotatus), Culex and Psorophora. In a mosquito distribution project in Buenos Aires, Argentina, we found nematodes infecting mosquito larvae in natural breeding sites in the outskirts of Mar del Plata city. The aim of this work was to identify this parasite in this distribution area and determine the mosquito species host. COI and 18S rRNAITS1-5.8S rRNA-ITS2-28S rRNA fragment genes were described and were used for molecular identification of this nematode, confirming the morphological diagnostic traits. In this report, a new host of S. spiculatus, the mosquito larvae of Culex eduardoi was detected, expanding its southeastern distribution.
