Abstract
The purpose of this note is to validate a name for a field cricket that occurs from western Texas to western Florida that has been incorrectly referred to as Gryllus integer. The type locality of a species first termed G. integeris California, but the range of this species was described to include several locations in Texas. Alexander and Otte (1967) also used G. integer to refer to field crickets with a trilling calling song collected in eastern Texas. The calling song of G. integer from California consists of a series of very brief trills conposed of 2 or 3 pulses of sound, a so-called "stutter triller". This song is very different from the calling song of the trilling Texas species. Weissman et al. pointed out that the Texas species is not G. integer and that the name was used incorrectly. Also, these two species readily mated in the laboratory, but these matings produced no offspring. The Texas species has been widely studied and we propose that it be called G. texensis Cade and Otte because much of the research has been performed on Texas populations. G. texensis occurs in old fields, lawns, and any grassy habitat from western Texas to western Florida, north to Oklahoma and south into Mexico. A representative sonagraph of the calling song of G. texensis is in Figure 1. The song consists of a series of pulses grouped together into trills of varying lengths and produced at an average wing stroke or pulse rate of approximately 80 per second at 25 C. Drawings of the morphology and genitalia of G. texensis are in Figure 2. The type specimens for male and female G. texensis were collected from the grounds of the State Capital in Austin, Texas in August, 1998 and are deposited in The Academy of Natural Sciences, Philadelphia.
