Opisthoscelis subrotunda Schrader, 1863 (Eriococcidae: Opisthoscelis)

Nomenclatural History

• Opisthoscelis subrotunda Schrader 1863a: 7. Type data: AUSTRALIA: New South Wales, on Eucalyptus sp. Unknown type status, both sexes, accepted valid name Notes: Schrader's collection was destroyed on July 30, 1943 during WWII according to Weidner in personal communication to Gullan. Illustr.
• Opisthoscelis gracilis Schrader 1863b. Type data: AUSTRALIA: New South Wales. , both sexes, junior synonym (discovered by Frogga1894, 209). Notes: Schrader's collection was destroyed on July 30, 1943 during WWII according to Weidner in personal communication to Gullan. Since Schrader's description of the adult female with long thin legs and a slender body, and the adult male with no anal setae, suggest to Hardy and Gullan (2010) that this was a species of Tanyscelis and should be considered a nomen dubium.
• Opisthoscelis globosa Rübsaamen 1894: 214. Type data: AUSTRALIA: New South Wales, on Eucalyptus sp. , both sexes, junior synonym Notes: Types of Rübsaamen in the ZMHB apparently were destroyed during World War II (Gullan, 1984). Opisthoscelis globosa Froggatt (1929) was a junior primary homonym of O. globosa Rübsaamen (1894). The replacement name O. rubsaameni Lindinger was put forth for the junior homonym. Illustr.

Remarks

• Systematics: Schrader (1863) described and illustrated Opisthocelis subrotunda based on insects and galls from an Eucalyptus sp. collected in New South Wales. His collection was destroyed on July 30, 1943, during WWII. Rubsaamen (1894 described a number of australian Gall-inducing insects, including O. globosa from Eucalyptus. in New South Wales. it is believed that this material also was destroyed during WWII. Froggatt (1921a) and Lindinger (1943b) both synonymized O. subrotunda with O. globosa Rubsaamen. Hoy (1963) concluded that the status of these species was confused and further study was needed. Hardy & Gullan (2010) have accepted synonymy of these two species based on a perfect match of Schradr's and Rübsaamen's descriptions and illustrations of the insects and their galls. Lindinger (1943b) realized that O. globosa Froggatt (1929) was a junior primary homonym of O. globosa Rübsaamen (1894). The replacement name O. rubsaameni (sic) Lindinger was proposed for the junior homonym. Hardy & Gullan (2010) have currently synonymized these two species. Adult females most closely resemble those of O. beardsleyi. (Hardy & Gullan, 2010)
• Structure: Species induces green galls, usually perfectly round. Female gall on leaf, opening varialbe, slit-like, sometimes with "lips" projecting, opening on abaxial or adaxial surface, but usually on same surface on any one leaf or plant. Mature female fills gall cavity with her abdominal apex directed downwards towards and plugging gall orifice. (Hardy & Gullan, 2010) Male gall is much smaller, but resembles that of female. Adult scale reddish yellow to brown, covered with fine close hairs and white meal, almost round (Froggatt, 1921a).
• General Remarks: Detailed description by Froggatt (1921a) includes a photograph of galls. Rübsaamen gave a detailed description and illustration of male and female galls, adult male and female insects as well as first instars (1894). Hodgson (2002) used this species in a phylogenetic analysis of non-margarodid Coccoidea. Recent description, photograph of galls and illustration in Hardy & Gullan (2010)
