Discussion. This rare species is endemic to Hispaniola. The holotype was described from Haiti, and since that description only three additional specimens have been discovered.

It is similar in color and elytral pattern to D. hovorei and D. elegans . All three species have similarly vittate elytra. Solenoptera vittata differs from D. elegans by its pronotum and elytra which are distinctly punctate (glossy in D. elegans ). It differs from D. hovorei by lacking large, lateral, spinelike pronotal processes (present in D. hovorei ). It is further distinguished from D. hovorei by having the prosternal process not lobed or notched at the apex (strongly bilobed in D. hovorei ). Other characters distinguishing this species from D. hovorei are discussed and illustrated in Lingafelter and Woodley (2007) and under the account of D. hovorei herein. Prosternodes oberthuri Gahan was synonymized with this species by Galileo and Martins (1993a).

Originally described in Prionus Geoffroy, 1762 by Olivier (1795), this species subsequently has been placed in Solenoptera , Elateropsis , and Derancistrus . Galileo and Martins (1993a) most recently proposed the new genus Derancistrodes for it, but they did not elaborate which characters were unique for that genus. Based on examination of both sexes and examination of most species of Solenoptera , I conclude that Derancistrodes is a new synonym of Solenoptera . It shares all the characters of that genus (pronotum lacking distinct anterolateral spine, prosternum with punctation in males but absent from females, protibia of males with dense brush of pubescence on apical half that is absent or greatly reduced in females, and broad, rounded scutellum). The only character that is atypical of the genus Solenoptera is the prosternal process which is not lobed at the apex.
