Taxonomy

This species was first described by Scorza and Dagert in 1956. It was redescribed in 2003 by Telford.[1]

Description

The asexual stages are irregular in shape and do not have a vacuole.

Schizonts measure 6.2 × 4.5 micrometres (range: 4 – 8 × 3 – 6) and produce on average 11.9 (range: 7 – 16) merozoites.

Gametocytes average 12.4 × 6.0 micrometres (range: 8 – 16 × 4 – 10). The average length × width product is 72.9 (range: 52 – 112) and the average length / width ratio is 2.18 (range: 1.1 – 3.3). The gametocytes always contain 1 – 5 prominent vacuoles.

Macrogametocytes during active infection are longer than microgametocytes with a greater length-width product. Gametocytes in chronic infection are slightly smaller and are not sexually dimorphic in their dimensions.

Distribution

Found in Venezuela, South America.

Hosts

Known hosts are the lizards Ameiva ameiva and Kentropyx calcarata.
