Abstract
Steinernema puertoricensis n. sp., isolated from sand collected from a coconut plantation, can be distinguished from S. glaseri, its most cl osely related species, by characteristics of the first generation adul ts. The female has a greater body length (8.6 mm) and width (375 mu m) . Males have the excretory pore anteriad or posteriad to the nerve rin g. Spicules are arcuate and lack a hook at the ventral side of the spi cule tip. Infective third-stage juveniles are over 1 mm in length. Thi s appears to be the first species of Steinernema described from the Ca ribbean islands and adapted to a hot humid environment.
