Abstract

A new species of Cyphophthalmi (Opiliones) belonging to the Sri Lankan genus Pettalus is described and illustrated. Characterization of male and female genitalia and SEM illustrations are included, representing the first such analysis for the genus. This constitutes the first species of Pettalus to be described since 1897, although information on other morphospecies recently collected in Sri Lanka indicates that the number of species on the island is much higher than previously thought. The presence of eyes in pettalids is illustrated for the first time and the implications of the presence of eyes outside of Stylocellidae are discussed.
