Platynectes submaculatus species group

This species group has members with an entirely lightly colored venter, typically light red to orange in color, and lacking distinctly infuscate regions. There are some specimens with darker metaventral and abdominal regions, but they differ significantly from the infuscate regions exhibited in P. agallithoplotes sp. nov., the sole member of the eponymous species group. We suspect that this current grouping could be further subdivided based on size and maculate pattern, but for now we take a conservative approach, erecting this species group to unite most of the northern South American species with light colored venters.
