Remarks

• Systematics: The host plant of T. cordaliae was given as "Cordalia lineata" in the original description (see translation above under diagnosis). Leonardi (1911) apparently named the species after its host, but spelt the name incorrectly, since there is no plant genus "Cordalia". Lizer y Trelles (1939) apparently noticed the error, and emended the name to T. condaliae (Leonardi), however, this was an unjustified emendation of the name (see articles 32.2 and 32.5 of the Code (ICZN 1999)). Leonardi (1911) wrote the host genus of his new lac insect as "Cordalia" and the lac insect name "cordaliae" thus is consistent with the original published name for the host plant. The unjustified emendation to "condaliae" was used by subsequent authors (Sharma & Ramani 1999; Varshney 1997, 2009, 2010) but was treated as a misspelling of the species name by Ben-Dov (2006). Morrison (1919) suggested that this species was a junior synonym of T. lycii, but this is unlikely. (Kondo & Gullan, 2011)
• Structure: The test is similar to that of the T. lycii, except that, on the dorsum, instead of having a single hump, this one has two conspicuous humps. With a large aperture corresponding to the anal opening. Walls of the test thick. In cases where the lac of individuals are close to each other, their lac merges to form a protective envelope, forming an encrustation. Color of the test dark purple.
