General Information
Term prescutum ID (Ontology) FBbt:00004582 (Fly Anatomy)
Definition The anterior part of the mesothoracic tergum, partially separated from the scutum by the intrascutal suture and separated from the humerus by the prescutal suture (FBbt:00004573).[ FlyBase:FBrf0007734 FlyBase:FBrf0027793 FlyBase:FBrf0166419 ]
Comment The usage here follows Bryant and is probably consistent with Snodgrass, 1935 (the anterior of the mesonotum between the prescutal suture (FBbt:00004573) and the antecostal suture(?)). It may also be consistent with the 'Dictionary of Insect Morphology', which defines it as 'the anterior part of the scutum, separated from the basiscutum by the anterior scutal suture'. However it differs from Ferris, 1950, who uses the term prescutum to refer to the pronotum (see figure 11).
