(e-mail: [email protected]) Abstract.-The genus Stringaspidiotus MacGillivray, 1921 is synonymized with Pseudaonidia Cockerell, 1897 as a junior subjective synonym (new synonymy) and the type species of Stringaspidiotus (Aspidiotus (Pseudaonidia) curculiginis Green) is redescribed and illustrated. Key Words: armored scale, Furcaspis, synonym, Pseudaonidia, description While writing a revision of the genus (later included in the genus Selenaspidus Furcaspis Lindinger (see Williams et al. Cockerell by Fernald' (1903)). At the 2006), we noted that the monotypic same time MacGillivray synonymized S. genus Stringaspidiotus MacGillivray jerox Lindinger with S. celastri. Mamet had been synonymized with Furcaspis (1958) discovered that MacGillivray's by earlier authors. After examination of concepts of F celastri were not correct the type species, S. curculiginis (Green), and redescribed F celastri and F jerox we concluded that it is not a species of as separate species in Selenapidus, thus Furcaspis and should not be included in leaving Stringaspidiotus as monotypic. our study. However, it seems appropriate Lindinger (1909) included A. (Pseudao to present the results of our analysis nidia) curculiginis in the genus Furcaspis concerning the placement of the genus Lindinger. Although Ferris (1937) listed and species in a separate publication. the type species of Stringaspidiotus as The purpose of this paper is to illustrate Aspidiotus curculiginis, he illustrated and redescribe the species S. curculiginis Green's species as Stringaspidiotus curcu and to provide evidence supporting our liginis and remarked that Stringaspidiotus hypothesis that Stringaspidiotus is a ju was very doubtfully distinct from Furcas nior synonym of Pseudaonidia Cockerell. pis. When Balachowsky (1958) described The genus Stringaspidiotus MacGilliv the subtribe Furcadaspidina (of the tribe ray (1921), at present includes the single Aspidiotini Westwood), he included five species S. curculiginis, described origi genera: Furcaspis (type species Aspidiotus nally as Aspidiotus (Pseudaonidia) curcu bi/ormis Cockerell), Neojurcaspis Green liginis by Green (1904) from Java. (type species N. andamanensis Green), MacGillivray also included Aspidiotus Paraonidiella MacGillivray (type species articulatus var. celastri Maskell described Aspidiotus cladii Maskell), Separa from South Africa by Maskell (1897) spis MacGillivray (type species Furcaspis 774 PROCEEDINGS OF THE ENTOMOLOGICAL SOCIETY OF WASHINGTON , " . : I .1 : 7' ' ~ : ; : Fig. I.
