| In well-preserved specimens, this layer forms an undulating coat that covers the entire sclerite. |
|
| Burke interpreted the ventral sclerite as being solely comprised of the sternite fused with the coxae. |
|
| Collectively, these observations suggest that the thin outer layer is a primary feature of the sclerite wall. |
|
| This suggests that the sclerite wall curved into the cavity, forming a short canal or tube. |
|
| Sometimes a large surface sclerite called a carapace covers both the head and the thorax, as in crabs and lobsters. |
|
| There is a well sclerotised sclerite located ventrally to S8, which cannot be interpreted as anything but a tergal part. |
|
| All statements of sclerite position refer to the unexpanded left bulb from its ventral view. |
|
| Presternum with 1 or 2 inconspicuous setulae on each half of sclerite. |
