This tergal modification seems to occur only in micropterous specimens, with reduced forewings. |
|
It is microphthalmic, micropterous, depigmented, with reduced size, globular shape, and short and robust appendages. |
|
However, females are not a problem, because they are apterous or micropterous in Embolemus and macropterous in Ampulicomorpha. |
|
Such characters are typical of shortened wings, which can be divided into brachypterous and micropterous forms. |
