A review of the whitefly genus Aleurocanthus Quaintance & Baker (Hemiptera: Aleyrodidae) in Australia Gillespie, Peter S. Zootaxa 2012 3252 1 42 [151,491,1763,1789] Insecta Aleyrodidae Aleurocanthus Animalia Hemiptera 28 29 Arthropoda species octospinosus sp. nov.   Etymology.The name is derived from the distinctive four pairs of long glandular spines found on the margin of this species.   Distribution.NE NSW, SE Qld.  Hosts. PROTEACEAE:  Macadamia integrifolia,  M. ternifolia.   Material examined. Holotypepuparium slide: Australia, NSW, Fernleigh near Ballina, damaging  Macadamia integrifolia, 3.x.2001, P.Tully, ( ASCT00132209)( ASCU). Paratypes: same data as holotype, 10 xpuparia on six slides ( ASCT00025318, ASCT00027537-40, ASCT00132208)( ASCU), 1 x3rd instar nymph slide ( ASCT00132220) ( ASCU), approx 300 x puparia and nymphs on 7 leaves ( ASCT00027536)( ASCU); Manorina, Mt Nebo, Qld, 16.vii.2004, Coombs & McNeil, ex  Macadamia ternifoliaRef317, 1 xpuparium slide ( ASCT00169502)( ASCU), 7 xpuparia on 7 slides (20-013560)( ANIC). Non typematerial: Qld, Bunya Mtns, 22.ii.1997, P.J. DeBarro, 4 xpuparia on one slide (AN20.10730)( ANIC).   Comments.This species is a minor pest in macadamiaplantations in northern NSW where it was first brought to the author’s attention. The characteristic colouration and the number and arrangement of long glandular spines of the puparium uniquely identify the species which is closely related to  A. mcneilibut differs in having a darker colouration and one fewer pair of long marginal glandular spines. The material collected from Bunya Mountains was excluded from the typeseries because it is damaged and not properly cleared. The specimens collected on  M. ternifoliawere found in the company of  Pseudosynaleurodicus nigrimarginatus– a whitefly restricted to this rare and endangered host (see Gillespie, 2006). This species was previously known as “  Aleurocanthusundescribed sp. 4” ( Martin 1999) and belongs to the ‘ banksiae-valenciae’group.
