| Summary: | Hyperomyzus (Neonasonovia) nabali (Oestlund, 1886) Rhopalosiphum nabali was described by Oestlund (1886: 34) and subsequently transferred to Amphorophora Buckton, 1876 by Oestlund (1923: 143). It was later transferred to Neonasonovia when this taxon had genus rank, by Hille Ris Lambers (1974: 132), and finally to Hyperomyzus (in the subgenus Neonasonovia) by Eastop & Hille Ris Lambers (1976: 121). Viviparous females have been formally described; they have ornamented siphunculi. The species is host-alternating between Ribes, as primary host, and Prenanthes. It is known in Manitoba, New Brunswick, Newfoundland and Quebec (Canada), and in the District of Columbia, Illinois, Kansas, Massachusetts, Minnesota, Missouri, New York, North Carolina, Ohio, Pennsylvania and Utah (United States). Studied specimens. Canada: New Brunswick, Fredericton, on Prenanthes alba, 3-IX-1956, Hille Ris Lambers & MacGillivray leg. and 6-VII-1960, MacGillivray & Anderson leg., respectively 6 apt and 3 apt; Quebec, Laurentide Park, on Ribes glandulosum, 28-VIII-1956, Hille Ris Lambers leg., 4 al (gynoparae) & 4 ov; all specimens: Hille Ris Lambers det. and Natural History Museum collection. Apterous viviparous females, virginogeniae or exules (Figures 1 A, 1B), complementary data. The dorsal sclerotization and pigmentation is diverse: in six studied specimens the dorsum is completely pale, as previously described, with very faint rough cuticle around the base of setae and markedly rough sclerotized areas in abdominal segments 6 to 8. In the other three studied specimens there are relatively extensive, rough and pigmented setiferous sclerites in abdominal segments 2 to 8, which sometimes merge to form transverse bands. Antennae from yellowish-brown (in specimens without setiferous sclerites) to brown (in specimens with these sclerites), with darker segment VI and small distal portions of the other segments of antennal flagellum. Legs mostly yellowbrown to brown, tarsi and the apex of tibiae as dark as antennal segment VI. ... |
