Dasineura acaciaelongifoliae ( Skuse, 1890)

[ Fig. 2 g]

Cecidomyia acaciae-longifoliae Skuse, 1890: 374.

Dasineura acaciaelongifoliae , new combination by Gagné in Gagné & Marohasy (1993: 80). Dasineura acaciaelongifoliae , redescription in Kolesik et al. 2005: 469.

Material studied. Syntypes, males and females, “Sydney (Skuse). Five males (one designated here as lectotype, ANIC 29-38458, other four as paralectotypes, ANIC 29-38457,59,66,68), 9 females (paralectotypes, ANIC 29- 38460–5,67,69,70) and 7 pupal skins (paralectotypes, ANIC 29-38471–7) were mounted.

Associated gall. Adults were “bred from bunches of brown, woody cylindrical galls formed on the flowerstalks of Acacia longifolia . The full-grown galls are usually from 12 to 18 mm. long, and occur in bunches of from two to twenty or thirty tubes; these tubes are rarely straight, being usually coalescent at the base and bending in an outward direction for their apical half. They are slightly constricted at the mouth, and clothed inside with white pubescence which evidently serves to facilitate the egress of the pupa (Pl. XVI., figs. 1-1b [ Fig. 2 g]).”, in ANIC.

Remarks. The types were investigated, new specimens reared and their cytochrome B mitochondrial gene fragment sequenced, and the species redescribed by Kolesik et al. (2005) who found it feeding on A. longifolia , A. sophorae , A. sophorae x A. oxycedrus , A. implexa , A. stricta and A. maidenii .
