Identification
The middle of the three main divisions of the dorsal surface of a thoracic segment. Also, in ticks, the sclerotized plate covering all or most of the dorsum in males, and the anterior portion in females, nymphs, and larvae of the Ixodidae.
The anterior sclerite of a notum, in front of the scutellum. In Apocrita, the mesoscutum is functionally only the area in front of the transscutal articulation; the axilla, although morphologically part of the mesoscutum, is treated as separate.
