The holotype (AMNH 29273) from the Early Devonian-aged (Emsian–Eifelian, sensu Hernández et al., 2018) Icla Formation in Bolivia was originally described as having slit-shaped LCEs on both sides of the anterior prosomal shield ( Eldredge, 1974). We corroborate this observation ( Fig. 5A, B). Lateral compound eyes are located ~ 21 mm from the midline of the prosomal shield along well-defined ophthalmic ridges. Furthermore, we report that well-preserved ommatidia are expressed in the facets of the LCEs ( Fig. 5C) ( Eldredge, 1974). At least 26 ovate ommatidia are preserved on the left LCE. Sizes range between 0.39 and 0.61 mm wide, but are mostly ~ 0.6 mm wide.
