Abstract
The Cymatodera Gray fauna of Baja California (the Mexican states of Baja California and Baja California Sur) comprises fifteen species, of which six (C. minacis Barr, C. intermedia Barr, C. fascifera LeConte, C. santarosae Schaeffer, C. cephalica Schaeffer, and C. purpuricollis Horn) are endemic to the peninsula. Three of these endemics (C. intermedia, C. cephalica, and C. purpuricollis) are apterous. The remaining nine species are more broadly distributed, with ranges that extend north into the U.S. border states. This paper describes a new species of fully winged, endemic Baja Cymatodera. The new species is identical in facies to C. minacis Barr, and the two can only be distinguished by differences in the male terminalia. Indeed, when I examined Barr’s type series of C. minacis, I discovered that it was actually comprised of two species: among labeled paratypes of C. minacis were several examples of the new species described herein. Barr’s original description of C. minacis (Barr 1950: 497) does not include a description of the aedeagus, which is not everted in the holotype male specimen. However, some of the male paratypes from the type locality (Triunfo, Baja California Sur) do have the terminalia visible, and all of these exhibit recurved parameres and tapered phalluses. The type series was collected at Triunfo on the same day in July, and there is no doubt the holotype has this form of aedeagus, which is illustrated here for the first time. The new species has distinctly different terminalia which are also illustrated.
