Abstract

A unique specimen of the Sergeant coquito Nexilosus latifrons(Tschudi, 1846) was captured in Taltal, Northern Chile, using a spear gun. This specimen was collected in an area that lies midway within its recorded natural geographical distribution where its presence had not previously been documented. Therefore, this finding significantly contributes to the continuous extension of the species' range in this area. This study underscores the importance of carefully examining this geographical expansion and emphasizes the need for further research and sampling to obtain more specimens in the region.
