Diaspis lutea (Newstead, 1911); Hargreaves 1937: 516. change of combination Notes: Lindinger (1949) stated that Diaspis lutea Newstead was an invalid name due to the senior name Diaspis lutea Lancry, however, the two names are not homonyms, having never been in Diaspis at the same time. Even Lindinger, who noted the problem, did not suggest a replacement name. It is probable that Hargreaves created the new combination accidentally.

Systematics: Chionaspis lutea is close to Indian species like Unaspis flava and Aulacaspis litzeae, but is distinguished chiefly by the absence of long spinose gland spines on the pygidium, and the broader duplex lobes (Newstead, 1911a). Hall (1946a) felt that Chionaspis lutea does not belong in Chionaspis. He states that the characters of the pygidium are typical of Diaspis, yet the body shape is not turbinate and the female scale is typically Chionaspiform with terminal exuviae. The shape of the scale shows considerable variation according to position, some being narrowly elongate while others are much broadened posteriorly. Were it not for this, one would have no hesitation in assigning it to the genus Diaspis."
Structure: Puparium of male smooth and flat, without any trace of carinae. Female puparium narrowly pyriform, sometimes slightly curved, exuviae and secretionary portion yellow, thin and semitransparent, revealing the sublying skins (Newstead, 1911a).
General Remarks: Best description and illustration by Newstead (1911a).
