sclerite's Usage Examples:

Turning to the thorax we find that the first segment (prothorax) is distinct and free, with a wide dorsal sclerite.

- Prosoma longer than wide, its sternal area very narrow, furnished with a large prosternal and metasternal plate, and often with a small mesosternal sclerite.

its attachment to the trunk, we find a highly complex series of small sclerites adapted for the varied movements necessary for flight.

- Integument hard, strengthened by a continuously chitinized dorsal and ventral sclerite.

The ventraPscleriteof the head-skeleton (gula), well developed in most families of beetles, is absent among the Rhynchophora, while the palps of the maxillae are much reduced.

Ductless Glands >>The glands occur in groups, and lead into common ducts which open usually so much reduced that the foremost apparent ventral sclerite of the abdomen represents the third sternite.

Below each eye is a cheek area (gena), often divided into an anterior and a posterior part, while a distinct chin-sclerite (gula) is often developed behind the mouth.

The head is usually connected with the thorax by a distinct membranous neck, strengthened in the more generalized orders with small chitinous plates (cervical sclerites).

There is also a pair of narrow tergal sclerites interposed between the anterior and posterior shields.

an, Orifice within which the caudal a, Movable (hinged) sclerite (sosegments are withdrawn.

ventral cervical sclerites III, Hind leg and metasternum.

The dorsal area of the mesothorax, and also of the metathorax, may be made up of a series of sclerites arranged one behind the other - prescutum, scutum, scutellum and post-scutellum (fig.
