Notes.

This species is similar to G. assectator (Linnaeus), but differs by having a slightly longer head in dorsal view, the vertex more convex in lateral view, the hind tibia more slender, the pronotal teeth more or less developed and the mandibles brownish-yellow or yellow (dark brown in G. assectator). Closely related to G. bicoloratum Tan and van Achterberg and differs mainly by the shape of the head as illustrated in the key.
