Psyllinae

Arytainilla spartiophila ( Foerster, 1848)

Distribution: Europe; introduced as bio-control agent into Australia, USA and New Zealand: BP, CO, DN, FD, HB, KA, MC, MK, NC, NN, RI, SC, SL, WA, WI, WO ( Syrett et al. 2007); TO (FHDB).

Host plants: Cytisus scoparius (Fabaceae) .

Baeopelma foersteri ( Flor, 1861)

Distribution: Europe, Northern Africa, Middle East; introduced into New Zealand: AK, WI ( Dale 1985, as Psylla foersteri ).

Host plants: Alnus glutinosa , A. incana (Betulaceae) .

“ Psylla ” apicalis ( Ferris & Klyver, 1932)

Distribution: New Zealand: AK, BR, CL, NN, WD ( Dale 1985, as Euphalerus apicalis ), FD, ND ( Tuthill 1952), MC ( Ferris & Klyver 1932, as Psyllia apicalis ; Dale 1985).

Host plants: Sophora microphylla , S. prostrata , S. tetraptera (Fabaceae) .

Comments: Tuthill (1952) stated that the species resembles Euphalerus nidifex Schwartz in appearance but left it in Psylla until a more adequate concept of Neotropical Euphaerus becomes available. He also suggested that the Oriental and Pacific species referred to as Euphalerus depart widely from the type species E. nidifex . Dale (1985) pointed out important differences of the immatures of P. ap i c a l i s and P. carmichaeliae to those of E. nidifex . However, based on the resemblence of adults to E. nidifex and two Japanese species referred to as Euphalerus , she transferred the two New Zealand species to Euphalerus . Hollis & Martin (1997), when redefining Euphalerus to include only New World species, confirmed Tuthill’s (1952) suggestion that Asian species referred to as Euphalerus are not congeneric with the type species. The last instar immatures of the two New Zealand species possess 8-segmented antennae, marginal setae on the caudal plate, a ventrally positioned anus with a unilayered circumanal ring and lack additional porefields on the caudal plate. These characters place the two species in the Psyllinae but outside Psylla and probably in a new genus. While awaiting a revision of the species they are left here in Psylla .

“ Psylla ” carmichaeliae Tuthill, 1952

Psylla carmichaeliae indistincta Tuthill, 1952 ; Dale 1985: 196.

Distribution: New Zealand: AK, CL, MC, ND, NN, TK, TO, SL ( Dale 1985, as Euphalerus carmichaeliae ), CO ( Tuthill 1952; Dale 1985, as Euphalerus carmichaeliae ), MB, WD ( Tuthill 1952, as Psylla carmicaheliae indistincta ; Dale 1985, as Euphalerus carmichaeliae ), OL ( Tuthill 1952); WN (FHDB).

Host plants: Carmichaelia spp. ( Fabaceae ).

Comments: Tuthill (1952) erected Psylla carmichaeliae indistincta for populations from Fox Glacier and Rai Valley , but Dale (1985) showed that these lie within the morphological range of the nominal species and synonymised the two. Henderson et al. (2010) listed the two taxa separately. ‘ Psylla aff. carmichaeliae ’ has been listed as a threatened species in New Zealand ( Stringer et al. 2012). Its host plant, Carmichaelia torulosa , is nationally endangered.
