Nomina nuda

Echinicerya echinatus . Nomen nudum created by Ben-Dov (2005: 177), discovered by Unruh & Gullan (2008: 36).

Guerinococcus . Nomen nudum created by Berlese (1909: 498), discovered by Morrison & Morrison (1966: 88).

Guerinococcus serratulae . Nomen nudum created by Berlese (1909: 498).

Icerya peninsularensis . Nomen nudum created by Ben-Dov (2005: 195).

Remarks. Newstead described I. formicarum originally from immature specimens. Rao (1951a: 55) compared these specimens with third-instar nymphs from a collection of specimens that he had given “the manuscript name of peninsularensis ,” a name he never published. According to Rao, the specimens were identical and he described adult females of I. formicarum from his (Rao’s) own collection. “ Icerya peninsularensis ” is not a nomen nudum discovered by Rao, as stated in Ben-Dov (2005: 195). Thus, Ben-Dov has created a nomen nudum.

Icerya ordinata . Nomen nudum created [not discovered as in Ben-Dov (2005: 206)] by Vayssière (1926: 336).

Remarks. Morrison (1921: 639) examined specimens collected by I.H. Burkill on Michelia champaca at the Botanic Gardens, Singapore, April 9, 1916, and on Rhopaloblasta palm in Singapore, February 1917, that were given “the manuscript names Icerya ordinata and I. palmarum , respectively,” by E.E. Green. He compared these specimens with Leonardi’s original description of I. pulchra and found no “differentiating characters” aside from wax colour. Vayssière (1926: 336) later reviewed I. pulchra , and stated that he also examined Green’s specimens of I. ordinata and also found concordance with I. pulchra , but failed to specify that I. ordinata was a manuscript name of Green’s, thus creating a nomen nudum.

Steatococcus anonae . Nomen nudum created by Vayssière (1926: 307), discovered by Foldi & Ben-Dov (2001: 461).
