Identification

Field Guide Descriptions:	Online Photographs: BugGuide, Google Images, iNaturalist, GBIF	SINA 007a.htm
Comments: Green but with a dark line along the carina of the pronotum in some specimens.
Structural Features: Very similar to carinata but males have a stridulatory field that is much larger in area than the pronotum; in carinata, it is similar in extent (Rehn and Hebard, 1914). The lateral carina of the pronotum are more rounded in oblongifolia than in carinata, especially in the apical fourth, where the carina may be obsolete. The ovipositor is regularly arcuate, armed with teeth along the margins; in carinata, the ovipositor is straighter and the teeth are smaller (Rehn and Hebard, 1914).
