description: Cyamophila floribundae Cho & Burckhardt, sp. nov.
(Figs. 54, 69, 71, 73, 75, 77, 79−80)
Diagnosis. The new species is similar to Cyamophila hexastigma (Horváth, 1899). It differs in the surface spinules of the forewing which are denser and irregularly spaced, leaving only narrow spinule-free stripes along the veins. It differs from C. hexastigma also in the host: Maackia floribunda, rather than M. amurensis.
Description. Adult. Colour and structure similar to C. hexastigma. Body colour greenish (Fig. 54), yellowish in ethanol preserved specimens, with whitish pattern on head and thorax in young specimens becoming dark brown in overwintered individuals. Antenna yellow, segments 1 and 2, greyish brown, segments 4‒7 brown apically, dark portion becoming larger in more distal segments, segments 8‒10 brown to almost black. Forewing transparent, veins yellow or brown; membrane transparent, slightly yellowish, particularly towards the wing apex and in older specimens; in old specimens also sometimes yellow or ochreous stripes along veins in apical part; with each a conspicuous brown spot in the middle of cells m1, m2 and cu1 along wing margin; surface spinules present in all cells, densely spaced forming irregular transverse rows, leaving only narrow, spinule-free stripes along the veins. Terminalia as in Figs. 75, 77, 79−80.
Measurements (in mm; 3 ♂, 3 ♀): head width ♂ 0.92−0.97, ♀ 0.98−1.05; antenna length ♂ 2.08−2.34, ♀ 2.16−2.39; forewing length ♂ 2.86−3.10, ♀ 3.12−3.31; metatibia length ♂ 0.60−0.65, ♀ 0.66−0.69; proCtiger length ♂ 0.39−0.44, ♀ 0.77−0.83.
Type material. Holotype ♂, South Korea, JJ, Jeju-si, Halla Arboretum, 04.viii.2015, Maackia floribunda (G. Cho) (SNU; dry mounted). — Paratypes, South Korea: same data as holotype but, 10 ♂, 20 ♀, 1 immatures, (SNU, dry and slide mounted, in 95% ethanol); same data but, 1 ♂, 2 ♀, 5 immatures, 29.iv.2016 (D. Burckhardt & G. H. Cho) (NHMB, SNU; 70% and 95% ethanol).
Host plant. Maackia floribunda (Miq.) Takeda (Fabaceae), confirmed by the presence of immatures.
Etymology. Named after its host plant Maackia floribunda.
Comments. Cyamophila floribundae is morphologically similar to C. hexastigma and differs mostly in the distribution of the surface spinules. The male paramere is in average slightly stronger widened towards the apex in the former.
Psylla alniformosanaesuga Lauterer et al., 1988 (Figs. 55−57)
Psylla alniformosanaesuga LAUTERER et al., 1988: 72.
Psylla alni, KWON, 1983: 40, NEC LINNAEUS, 1758: 454, misidentification.
Material examined. South Korea: 1 ♂, 1 ♀ identified as Psylla alni, GB, Mt. Palgonsan, 18.vi.1983 (Y. J. Kwon) (NHMB).— South Korea (GB, GN, GW) (NHMB, SNU), Taiwan (NHMB).
Host plant. Alnus incana (L.) Medik. subsp. hirsuta A.Löve & D.Löve (Betulaceae), confirmed by the presence of immatures.
Comments. All previous records of Psylla alni from Korea (Kwon 1983; Park 1996; Kwon et al. 2015a) concern P. alniformosanaesuga. The former is excluded from the psyllid fauna of Korea.
