A new tiger beetle species, Cicindelidia melissa Duran & Roman, sp. n., of the tribe Cicindelini, is described from high elevation montane forests of southeastern Arizona and Mexico. It appears to be most closely related to C. nebuligera (Bates) but is distinguished on the basis of multiple morphological characters and geographic range. The new species is also superficially similar to the widespread C. sedecimpunctata (Klug), but distinguished on the basis of multiple morphological characters and habitat. Habitus, male and female reproductive structures, and known distribution map are presented.

The New World tiger beetle genus Cicindelidia
Specimens of a previously undescribed Cicindelidia had been collected over the past several decades by David Brzoska (Naples, FL), Ron Huber (Bloomington, MN), Walter Johnson (Minneapolis, MN) and John Stamatov (Armonk, NY) from a site in the Chiracahua Mountains of southeastern Arizona and from 29 localities in the Mexican states of Sonora, Chihuahua and Durango. Additional Chiracahua specimens were collected in 2009 by Eric Sangregorio and donated to the first author. In total the authors examined 153 specimens of the new species. Type material is deposited in the following institutional and private collections (acronyms used in the text are in parentheses): National Museum of Natural History, Smithsonian Institution, Washington, DC, USA (NMNH), Arizona State University Frank Hasbrouck Entomology Collection, Tempe, AZ (ASUHIC), Collection of David W. Brzoska, Naples, FL (DWBC), Ronald L. Huber Collection, Bloomington, MN (RLHC), Collection of Walter N. Johnson, MN (WNJC), Collection of Daniel P. Duran, Philadelphia, PA (DPDC), Collection of John Stam atov, Armonk, NY (JSC). Specimens were compared to material of all putative close relatives, including C. sedecimpunctata and it’s subordinate taxa mellyi and sallei, C. flohri, and C. nebuligera.
Images of the dorsal, lateral, and frontal habitus and elytral apex were captured using a Canon EOS 7D attached to a Visionary Digital Imaging System (Visionary Digital, Palmyra, VA). Images were then montaged and edited using Adobe Photoshop. Genitalia were extracted, manually cleaned with minuten pins and 10% KOH solution, and placed on glycerin slide mounts for observation and imaging. Scale bars were calibrated with an ocular micrometer using SPOT Advanced software on the images of the genitalia, which were taken with a digital camera attached to a Nikon SMZ1500 dissecting microscope. The final digital images were processed using Adobe Photoshop CS6. The distribution map was created with Quantum GIS Version 1.4.0.

This species can be distinguished from all other similar Cicindelidia by its dark green-violet abdominal venter with the two apical segments dull orange or orange-brown, a brassy-cupreous head and pronotum with metallic blue reflections in sulci, small shallow subsutural foveae present in most individuals, and microserrate elytral apices. It inhabits rocky upland soils in ponderosa pine forests above 2000 m (Fig.
Small to medium sized Cicindelidia. Body (Figs
Thorax. Pronotum 1.70–2.50 mm in width, slightly polished with metallic finish, brassy-cupreous with metallic blue or blue-green sulci, slightly wider than long, nearly trapezoidal in shape and widest near anterior margin, width to length ratio 1.2 to 1.3, setae sparse and present along lateral third of dorsal surface; disc finely rugose to vermiculate with thin but distinct median line and deeply impressed sulci; notopleural sutures clearly defined, not visible from dorsal view; proepisternum bright polished copper with gold and green reflections more ventrally, abruptly transitioning to blue-violet on ventral third and posterior third, in male setae present throughout surface of proepisternum, but in female setae are typically sparsely present only along ventral third and along anterior margin; all other ventral segments of thorax are glabrous, dark blue-violet to black with greenish reflections. Elytra elongate, 5.1–6.7 mm length, shape similar in both sexes, but slightly wider in female, especially toward apical third; sutural spine small to nearly absent, fine microserrations present on elytral apices (Fig.
Legs. Procoxae and mesocoxae dark metallic green to black, covered in dense setae; metacoxae dark metallic green to blue-violet to black, with a single apical setae present; trochanters glabrous, dark green to violet-black; femora dark metallic green with blue-violet reflections near the insertion of the tibia, femoral surface with rows of erect white setae dorsally and ventrally; tibiae violet to dark cupreous with dark green reflections near the apices, clothed with white setae that are sparser and shorter than those of the femora; tarsi violet with blue reflections dorsally, first three dilated protarsomeres in male with dense greyish-white setal pad.
Abdomen. Ventrites 1–4 dark violet with strong metallic greenish reflections throughout most surfaces, dark orange to testaceous coloration along lateral edges in some individuals, setae present mostly along lateral third of each ventrite; ventrites 5–6 orange to dark orange-testaceous throughout, setae present along lateral margins, but often abraded.

This new Cicindelidia is named after the first author’s wife, Melissa, for her constant support, love, and friendship.
C. melissa is currently known from northwestern Durango, western Chihuahua, eastern Sonora, and southeastern Arizona. All known occurrences are from forested hillsides and trails above 2000 m. Typical habitats contain rocky substrates derived from limestone and/or rhyolite, with forest cover generally dominated by Ponderosa pine. This species is mostly active following monsoon rains, but frequents upland areas and is not closely associated with muddy or riparian microhabitats.
Given the superficial similarity to C. sedecimpunctata in dorsal habitus, C. melissa may have been overlooked and assumed to be a form of that widely distributed species. However, despite the general resemblance, multiple diagnostic morphological characters exist, as discussed above. Previous authors acknowledged that additional cryptic species may be present in the C. sedecimpunctata/rufiventris group (
It is interesting to note that the ecological differences between C. melissa and C. sedecimpunctata are stark, and habitat alone separates the two species in almost all cases. Tiger beetle taxonomy has relied nearly exclusively on fixed morphological characters to date, yet we believe that this present example underscores the importance of habitat and ecological factors that may not be apparent when comparing dead specimens of tiger beetles. Given the ecological and morphological similarities and apparently allopatric ranges, we propose that C. melissa and C. nebuligera are most closely related. Increasingly, higher-level and species-level phylogenies are based on molecular data, in part or entirely, and recent authors have examined relationships of Nearctic tiger beetles (
