Diagnosis. Very similar to P. apodemus and P. darlingtoni of 
Cuba in external appearance. Differing mostly in shape of internal 
male and female genital structures. The male aedeagus of puer- 
toricensis when seen in lateral view has higher and broader lateral 
extensions at its posterior (fig. 6), than darlingtoni (fig. 3) and 
apodemus. The aedeagus of puertoricensis in dorsal view is wider 
and shows more regularity in the external outer surfaces at its 
posterior (fig. 5) than in darlingtoni (fig. 2) or apodemus (fig. 4). 
The female spermatheca of puertoricensis is more slender (fig. 7) 
than apodemus (fig. 8).
