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.
