The posterior part of dorsal scutum, recognizable as the part with parallel straight sides, posterior to the main slope change caused by the widened convex laterals is called ‘coda’ (Kury 2012).
In species with dorsal scutum alpha-conformed (Kury et al. 2007), recognition of a coda is trivial, but for those beta-conformed, by definition, the coda is not well-developed. However, in some beta-conformed cosmetids, a sharply defined coda may be recognized because the outline of scutum is not continuous in that region, giving the impression of an extra free tergite before the ordinary ones. This illusion is reinforced because there is a white transverse stripe across the coda which resembles the articular membrane separating the free tergites.
