Gryllus texensis

Cade & Otte, 2000

Texas Trilling Cricket

Gryllus texensis is a described by Cade and Otte in 2000, distinguished from the morphologically similar Gryllus rubens by differences in call song structure. The species was previously misidentified as Gryllus integer in collections from the southeastern United States. It belongs to a closely related complex of Gryllus field crickets and is phylogenetically most closely related to G. rubens based on mitochondrial analysis.

Identification

Gryllus texensis cannot be reliably distinguished from Gryllus rubens based on alone; identification requires analysis of call song structure. The was originally recognized through acoustic differences rather than physical characteristics, as Cade and Otte (2000) found no morphological differences between the two species. Specimens from the southeastern United States previously identified as Gryllus integer have been reclassified as G. texensis.

Distribution

Southeastern United States from Florida to Texas; recorded from Alabama, Arkansas, Florida, Kansas, Louisiana.

Behavior

Males produce a characteristic call song that differs significantly from that of Gryllus rubens, which was the basis for the description.

More Details

Taxonomic history

The was erected in 2000 to accommodate from the southeastern United States that had been misidentified as Gryllus integer. The description was based on acoustic analysis by Gray and Cade (1999) showing distinct call song differences from G. rubens despite morphological similarity.

Phylogenetic relationships

Huang et al. (2000) confirmed G. texensis and G. rubens as closest relatives based on mitochondrial analysis.
