Pseudorthocladius

- Two specimens of an apparently undescribed species were collected. Until this collection, Pseudorthocladius was not recorded from the Neotropical Region. The Zurquí species appears similar to P. clavatosus Saether & Sublette , but has a smaller inferior volsella. Pseudorthocladius clavatosus was described from two males and a female from South Carolina, U.S.A. ( Saether & Sublette 1983); comparison with type material will be necessary to determine if the Zurquí specimens represent a new species.
