Remarks

• Systematics: Aulacaspis mischocarpi resembles Pseudaulacaspis strobilanthi in the long serrated median lobes, but differs conspicuously in the form of the female scale, and in the margin beyond the lobes, which in P. strobilanthi is coarsely serrate and finely serrulate (Cockerell & Robinson, 1914). Tang (1986) treated A. thoracica as a junior synonym of A. rosarum stating "the characters for separating them mentioned by the former students are all unstable and can be observed even on the opposite sides of the same individual." Most recently (2013), Takagi synonymized A. thoracica with A. mischocarpi stating that he thought that the original description of P. thoracicia was based on specimens of P mischocarpi that had lost the long lateral setae since these easily drop off from their basal sockets. The records of "A. thoracica" from China remain problematical requiring critical re-examinations of the specimens. Tang's view suggests that the records of "A. thoracica in China included A. rosarum. (Takagi, 2013)
• Structure: Female scale circular, about 1.75mm in diameter, dull white, slightly transparent, exuviae lateral, very pale orange, the first skin projecting beyond margin of scale; second skin broad oval. Female, after boiling in KHO, pale yellow, elongated, broadened anteriorly, conspicuously segmented (Cockerell & Robinson, 1914).
• General Remarks: Detailed description and illustration by Cockerell & Robinson (1914). Detailed description and illustration of the junior synonym, A. thoracica by Robinson (1917). Based on the questions raised by Takagi, 2013, A. mischocarpi may only be known from Los Baños, Luzón Island
