Genus Phanogomphus

Phanogomphus Carle 1986

17 spp.

medium-sized, slender, and have small to moderate-sized clubs (S8 & S9) in males, barely present in females. All species have yellow patches on the club and yellow dorsal markings on most of the abdominal segments. All have brownish thoraces with two yellow lateral stripes. The shape and extent of the dorsal markings combined with the shape of the terminalia in males are the most reliable characteristics for identification. The restricted distribution of some species may help in their identification. All species are illustrated on Plates 7 and 8 in Dunkle (1).

The six widespread eastern species (Ashy, Beaverpond, Dusky, Harpoon, Lancet, Rapids) are not always identifiable from photographs. Clear dorsal and lateral photos of a specimen, and dorsal and lateral close-up views of male terminalia would be a significant contribution to BugGuide.
