intersegment

Between segments.

A telescoping section of an ovipositor, between its main segments.

The intersegments are homologous to the transverse conjunctivae of the preabdomen. They are frequently equal in extent to the segments themselves, functioning as a membranous sheath for the inclusion of the segments when at rest, and acting as a telescopic extension for the lengthening of the ovipositor when in operation.
