A series of paired longitudinal dorsal muscles passing from tergite to tergite of each successive segment.
Thorax much shorter than the head and than the first tergite.
A pair of dorso-ventral muscles passing from tergite to sternite in each segment.
Propygidium: the dorsal segment or tergite in front of the pygidilini, sometimes left exposed in Coleoptera.
Anal plate: in caterpillars, the shield-like covering of the dorsum of the last segment: in the embryonic larva the 11th tergite.
The tergite which covers the dorsal part of the first abdominal segment nearest to the thorax is, however, always present.
