Stenopelmatidae Part 2

After my disappointment that I couldn't find a live specimen for my first Stenopelmatidae post, I found one in my pool, extremely distended but perfectly preserved, and thought it a good opportunity to show off some insect anatomy. Below, I have an unlabeled photo and a labeled photo of the "face" of one of the Stenopelmatus species.

Stenopelmatus sp.

In case any of the labels are too hard to read, here they are listed, generally from top to bottom: Frons, Pedicel, Scape, Anterior Tentorial Pit, Frontoclypeal Suture, Clypeus, Abductor Tendon, Mandible, Labrum, Stripes, Postmentum, Prementum, Lacinia, Paraglossa, Hypopharynx, Galea, Maxillary Palp, Labial Palp. Now for a few other lovely pictures - In the ventral view, you can see the soft, unsclerotized endoskeleton that connects the sclerotized shield-like segments. This is necessary for insects, because if their whole exoskeleton were fused and sclerotized they would be unable to move.
