| In the basi-carinal corner of the valve there are often crests for the attachment of the tergal depressor muscle. |
| This tergal modification seems to occur only in micropterous specimens, with reduced forewings. |
| In places, portions of the sternites can be seen where the tergal cuticle has broken away. |
| Specifically, we examined the morphology of the tergal glands located on the 7th and 8th abdominal tergites and the subgenital plate. |
| Two pectoral feet somewhat smaller than the two tergal feet, about as long as the shell, slightly divergent, cylindrical. |
| The head of the stylopized female from Mason County is normal but it also has reduced metasomal tergal fascia and reduced scopal hairs on the hind tibia and basitarsi. |
