Nomenclatural History

• Opisthoscelis pisiformis Froggatt 1894b: 343-344. Type data: AUSTRALIA: New South Wales: Bathurst on Eucalyptus melliodora; Manly on E. robusta; Thornleigh on E. piperita; Sutherland on E. resinifera, by W.W. Froggatt. Syntypes, female, Type depository: London: The Natural History Museum, England, UK; Orange: Agricultural Scientific Collections Unit, Orange Agricultural Institute, NSW, Australia; accepted valid name Notes: Syntype gall material in ASCT. Also, galls which may be part of the type series are in BMNH. Gullan mounted three females from the BMNH galls in 1985. Type depository information provided by Gullan (personal communication, June 10, 1996). Illustr.

Remarks

• Systematics: Adult females of T. pisiformis are very similar to those of T. verrucula. Both species have 4 anal spines and a small but distinct anal ring that often appears horeshoe-shaped and has about 6 setae. Both have marginal abdominal spines that are smaller than the anal spines, and they frequently have paired quinquelocular pores. T. pisiformis can be distinguished from those of T. verrucula by having 1) marginal spines restricted to the posterior abdominal segments vs. marginal spines also occurring along margin on head and thorax, 2) mach smaller eyes, 3) more elongate flagellate setae on dorsal surface of posterior abdominal segments, and 4) no weakly-sclerotixed pads or protuberances near the spiracles. (Hardy & Gullan, 2010)
• Structure: Female galls green, tinged with reddish-brown, soft globular excrescences covering the leaves, basal orifice on the underside of the leaf, keyhole in shape. First-stage female pale yellow, almost a regular oval, looking very much like a small seed. Second stage salmon-pink in color, oval. (Froggatt, 1894b). Gall opening an almost closed slit in young galls; in mature galls, slit-like to oblong, on abaxial leaf surface. Gall opening on small raised or low conical protrusion, opposite side of leaf sub-spherical, basal attachment may be constricted. (Hardy & Gullan, 2010) Male galls conical, brown, truncate apex, with an irregular oval aperture. Immature males in these cells pale red, swathed in thick white felty sacs (Froggatt, 1894b). Male galls on stem or leaf, conical, opeing round to oblong. (Hardy & Gullan, 2010)
