Description

Similar to the original description (see Rogers et al. 2012) including the following variations: branch 2V variable with one to three extremities, the tip of each with a cell pad. Branch 2A with a basal spine of varying shape from sinuate to straight ( Fig. 4 View Fig A–B). One or two basal cell pads produced. Anterior end sometimes arcuate or straight but always acute apically ( Fig. 4 View Fig A–B). Sub-branch III of branch 2D with varying shape from monoramal to biramal with various intermediate states. In some cases, three or five spiniform projections present in the posterior face of the sub-branch ( Fig. 4 View Fig C–D). In some individuals, two projections can fuse to form an elongate projection with two acute extremities ( Fig. 4 View Fig E–F) or form an elongate ramus sharing spiniform projections as in the original description (see Rogers et al. 2012).

Habitat

The specimens studied in the present work were all collected in natural pools in an Amazonian savannah in the Serra dos Carajás (Canga deposits), see Fig. 7B View Fig .
