Key to the males of Plumarius ocellatus species group

1. Vertex without punctures anteriorly; malar area as long as apical width of first flagellomere; lower area of genal bridge close to mandibular articulation with carinae ( Fig. 3 B)................................................. P. stangei sp. nov.

- Vertex moderate to densely punctate anteriorly; malar area longer (1.3–1.5x) than apical width of first flagellomere; lower area of genal bridge close to mandibular articulation smooth, without carinae.......................................... 2

2. Genal carina absent; area between preoccipital carina and suboral swelling without median longitudinal carina ( Fig. 1 D); area anterior to pronotal lobe with weak carinae; pronotal lateral carina without lower pocket............. P. oc e l l a t us sp. nov.

- Genal carina present, distinct; area between preoccipital carina and suboral swelling with median longitudinal carina ( Fig. 2 B); area anterior to, and inferiorly to pronotal lobe with conspicuous carinae; pronotal lateral carina forming lower pocket ( Fig. 2 D)................................................................................ P. culminatus sp. nov.
