Key: Step 388. Tanytarsini 31 Paratanytarsus

388a. Posterior thoracic mound with a finger-like projection (133h.jpg). (In general this is a good diagnostic character, but while the projection is usually large and conspicuous, in some specimens it is reduced to a tiny conical tubercle which can be rendered invisible by the way the exuviae is mounted.).

Paratanytarsus dimorphis

388b. Posterior thoracic mound without a finger-like projection.
