The first and second instars of Lecanodiaspis tingtunensis are described and illustrated. First instars are distinguished from other species of Lecanodiaspis by the arrangement of dorsal 8-shaped pores in six complete longitudinal rows and a partial row in the thoracic region and the number of labial, anal plate, and spiracular setae. Second instars are dimorphic with males possessing well developed 5-segmented legs, dorsal tubular ducts, and long hair-like setae on the venter between the antennae and on the abdominal segments. Females have fewer 8-shaped pores in transverse rows on the dorsum, as well as legs reduced to stubs and only one pair of hair-like medial setae on the venter.
