Ben-Dov, Y., & Williams, D.J. 2003 The identity of Aspidiotus guianensis Lindinger, 1957 (Hem., Coccoidea, Diaspididae).. Bulletin de la Société Entomologique de France 108(2): 166-167.

Notes: In a work discussing some miscellaneous Coccoidea, Newstead (1917) described some specimens under the name Aspidiotus camelliae Signoret with malformed squamae (now known as plates) from British Guiana (Guyana). Newstead recorded these specimens from Turkey, on Erythraspis glauca, 17IX.1915 (G.L. Bodkin). There is no such plant genus Erythraspis and Newstead must have mistaken the plant for Erythrina glauca (Leguminosae), often used as a shade tree in cocoa plantations. Newstead thought that the malformed appearance of the plates was due to disease rather than to fungi or parasites. Lindinger (1957) referred to Newstead's record as "A. [Aspidiotus] guianensis nom. nov.". This reference to Newstead's illustration and description validates Lindinger's name. There are 5 of Newstead's orginial slides, containing altogether 29 adult female and 4 second instar females, in the Natural History Museum, London. These specimens, therefore, must be regarded as syntypes of Aspidiotus guianensis Lindinger. The plates in many of these specimens appear to be normal. Furthermore, a critical study shows that the species is actually the same as Aspidiotus diffinis Newstead, described earlier by Newstead (1893: 281) from British Guiana (Guyana) and currently known as Hemiberlesia diffinis (Newstead). This species has been illustrated and redescribed in detail by Miller and Davidson (1998). The name Aspidiotus guianensis Lindinger, is here synonymized with Hemiberlesia diffinis (Newstead), syn. n. Some of Newstead's slides discussed here, also contain a few specimens of the species described in Newstead (1917) as Aspidiotus (Chrysomphalus) erythraspidis (Newstead) and again Newstead listed the host plant in error as Erythraspis glauca on which he based the name of the armoured scale. Among Newstead's original slides of Aspidiotus (Chrysomphalus) erythraspidis, there is also one specimen of A. guianensis Lindinger.
