Studies on Neotropical Phasmatodea XIII: The Genus Paracalynda Zompro, 2001 with Notes on Eusermyleformia Bradler, 2009 (Insecta: Phasmatodea: Diapheromerinae: Diapheromerini)

A detailed redescription and review of the north Central American genus ParacalyndaZompro, 2001 is presented, which presently contains only two known species. A re-description is provided for the type-species P. picta (Brunner v. Wattenwyl, 1907), which is only known from the unique male holotype. P. utilaensis (Zompro, 1998) was originally described as a subspecies of P. picta (Brunner v. Wattenwyl, 1907) but obviously represents a distinct species, hence it is here raised to species rank (n. stat.). Both species are illustrated and detailed figures show the significant genital morphology of Paracalynda. A detailed study of genital features has proven Paracalynda was previously misplaced in the “Bacteria group” (tribe Diapheromerini) and as a result the genus is transferred to Eusermyleformia Bradler, 2009. A discussion on Sermyleformia: Eusermyleformia is provided, which includes a list of the seven genera now contained in Eusermyleformia as well as an extended and more comprehensive diagnosis of this supposedly monophyletic rank-free taxon.
