This coconut insect has a wide distribution from Tanganyika, East Africa to Samoa in Polynesia.

The Guam specimens before me were collected by Bryan, Swezey and Usinger from coconuts in Inarajan in May and Yigo in November, and Swezey took one specimen from a royal palm at Agana, Oct. 3 . The National Museum material contains 21 specimens taken Sept. 7, 1938, "in coconut branch with wind injury" by Oakley.

This species has been recorded from Guam as Diocalandra taitensis (Guerin-Meneville) , because of confusion in the identification of the species. D. taitensis is a redder species with much less black coloring, it has a broader, flatter, differently shaped prothorax on which the interstices are very coarsely reticulate and make the surface dull. On D. frnnzenti the interstices on the pronotum are finely reticulate and the surface has a moderately shiny appearance.
