Bioacoustics of Neotridactylus archboldi

Variation . Within and between the 11 isolated sand ridge habitats occupied by this species, morphological and coloration differences are generally negligible, with the following exceptions. Adult females from the Mt. Dora, Trail, and Atlantic Coastal ridges have much paler middle and hind legs ( Fig. 21H, 21J ) relative to those found in other regions. Their abdominal segments may also appear rather pale, especially when distended with eggs. Adult males from these three ridges ( Fig. 21G ) are identical to those found elsewhere. Individuals from the southwestern Gulf coastal scrub (Collier County) have pale tan to yellow tegmina instead ( Fig. 21I ). These color variations initially made me suspect the presence of 2–3 additional species within N. archboldi , but examination of male epiprocts as well as molecular data (to be published in a forthcoming paper) have convinced me that there is only one species involved, albeit with multiple isolated populations that may be in the process of incipient speciation. Tooth counts for the male stridulatory file seem to decrease from north to south, ranging from a low of 57 at Cedar Key (Levy County), to 62 at Gold Head Branch State Park (Clay County), to 63 at Catfish Creek Preserve State Park (Polk County) to a high count of 72 at Seabranch Preserve (Martin County).
