Notes
Identification to species level follows
Aquino and Schaefer (2010)
based on the following characters: flattened head with eyes placed ventrolaterally and visible from below; laterally expanded nuchal plate; six pairs of lateral abdominal plates posterior to coracoids; thoracic plates present; three midventral plates between cleithral posterior process and first plate of ventral series; anal shield composed of single plate; second infraorbital laterally contacting to two ventral dermal plates; patch of odontodes present on anterolateral aspect of cleithrum at opening to branchial chamber; and caudal fin with series of around three dark bands (irregular in our specimens).
Thirteen individuals were caught by hand from submerged terrestrial vegetation (sampling site NH02). An example of a live specimen is pictured in Fig. 13.
