Tanyscelis spinosa (Froggatt, 1894) (Eriococcidae: Tanyscelis)

Nomenclatural History

• Opisthoscelis spinosa Froggatt 1894b: 341-343. Type data: AUSTRALIA: New South Wales, Sydney and Flemington, on Eucalyptus siderophloia, by W.W. Froggatt. Syntypes, female, Type depository: Orange: Agricultural Scientific Collections Unit, Orange Agricultural Institute, NSW, Australia; accepted valid name Notes: Syntypic gall material in ASCT. Type depository information provided by Gullan (personal communication, June 10, 1996). Illustr.
• Opisthoscelis fibularis Froggatt 1894b: 344-345. Type data: AUSTRALIA: New South Wales, Bathurst, on Eucalyptus sp., ?/02/189? and Victoria, Bendigo, on Eucalyptus sp., ?/09/189?, by W.W. Froggatt. Syntypes, unknown, Type depository: Orange: Agricultural Scientific Collections Unit, Orange Agricultural Institute, NSW, Australia; junior synonym (discovered by HardyGu2010, 59-62). Notes: Syntypic galls in ASCT. Type depository information provided by Gullan (personal communication, June 10, 1996). Illustr.
• Tanyscelis spinosa (Froggatt, 1894); Hardy & Gullan 2010: 59-62. change of combination Notes: Hardy & Gullan, 2010, type material of both Opisthocelis spinosa and O. fibularis and determined that the adult females are indistinguishable. The name O. spinosa has priority, as it was described on an earlier page than O. fibularis.

Remarks

• Systematics: Slide-mounted adult female with: legs long and slender; abdominal segments covered with many short setae (Froggatt, 1894b). Afult females of T. spinosa are most similar to those of T. mollicornuta and T. grallator. Adult females of T. spinosa and T. grallator also have the dorsum with weakly sclerotic cuticle and conical to papilliform evaginations. Adult females of T. spinosa can be separated from those of T. mollicornuta and T. grallator by having eyes, and lacking the fleshy projections that are in the place of eyes in T. mollicornuta and T. grallator.
• Structure: Female gall brown, broad and rotund at the base, coming to a sharp thorn-like tip. Chamber walls are thin. First-stage female bright yellow, smooth, shining, elongate. Second stage reddish-yellow, covered on the upper side with curly white hairs. Mature female fixed on the underside to the base of the gall. Female gall brown, pyriform. Female is attached to the floor of the gall, pale yellow. The gall base forms a red wart on the underside of the leaf (Froggatt, 1894b). Gall on leaf thorn-like, usually on adaxial leaf surface. Gall opening slitlike. Base of gall globose and decorticated (i.e., outer tissue cracking and lifting from tissue below), distal area tapered, apex truncate. (Hardy & Gullan, 2010) Male gall is green, rounded excrescences irregularly wrinkled on the summit. Adult male is salmon-pink (Froggatt, 1894b). Male gall on leaf, subconical, apex truncate, opening oblong. (Hardy & Gullan, 2010)
• Biology: Female gall grows on the upper surface of leaves, often in great numbers. Male galls occur with the female galls (Froggatt, 1894b).
