Psellidotus novella
Psellidotus novella is a in the , Stratiomyinae. The Psellidotus belongs to the tribe Stratiomyini, a group characterized by aquatic and that often exhibit striking patterns. Species in this genus are poorly known in the Neotropics, with most known only from original descriptions.

Identification
Psellidotus are distinguished from the similar Hedriodiscus by subtle morphological characters that become difficult to separate in the Neotropics, particularly in South America. The genus is characterized by features typical of Stratiomyini, though specific diagnostic traits for P. novella are not well documented in accessible literature. in this genus may exhibit patterned with horizontal banding, a trait common in stratiomyine that is hypothesized to be associated with of horizontally polarized light.
Similar Taxa
- HedriodiscusExtremely similar ; the two are easily separable in the Nearctic Region but distinction becomes fuzzy in the Neotropics, especially South America.

Taxonomic Context
The majority of in Psellidotus and Hedriodiscus in the Neotropics are very poorly known outside of their original descriptions. This reflects broader patterns of underdocumentation for Neotropical .
Visual Ecology
Stratiomyine often exhibit horizontal banding patterns on their , suggesting an ability to see horizontally polarized light similar to . This capability is common in aquatic and may assist in locating mates and suitable sites.
