Systematics: Myrtaspis lumbinianawas originally described as a member of Chionaspis. Later, it was excluded from that genus because of the antennae in the first instar which are not six- but five-segmented (Takagi, 1999). No alternative generic position, however, was proposed at that time. Varshney (2002) suggests that M. lumbiniana should be placed in a monotypic genus, Takagiaspis. Takagi (2020) places this species in the genus Myrtaspis because of the antennae in the first instar which are not six- but five-segmented.
Structure: Median trullae robust, produced, and appressed together, basally with a prominent clavate sclerosis. Second and third trullae with mesal lobule roughly serrate on oblique margin; with lateral lobule reduced into a small pointed process. Submedian and submarginal macroducts on abd III–V; lateral macroducts on prth, msth, mtth, and abd I– III, at times absent on prth. Lateral gland spines on abd I–III; marginal gland spines 5–10 on abd IV; 1–4 on V. (Takagi, 2020)
Biology: Female deeply mining under the bark. Males scales are often crowded together especially at parts of branches where females are mining. Male scales are perpendicular to the surface of the bark, standing on their anterior end and supporting each other.
General Remarks: Detailed description and illustration of first instar larva, both sexes of second instar and adult female as Chionaspis lumbinianain Takagi (1985).
