Hyperomyzus (Neonasonovia) inflatus ( Richards, 1962)

Nasonovia (Hyperomyzus) inflata was described by Richards (1962: 780) and was 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). Apterous viviparous females were described, and some features of alatae viviparae are known ( Blackman & Eastop, 2016), but they have not been formally described. They have smooth swollen parts of siphunculi. The species has been recorded on Hieracium and Solidago , although the last perhaps is an accidental host plant. The life cycle is apparently monoecious. The species is known from Maine, Minnesota, North Carolina and Pennsylvania ( United States).

Studied specimens. United States: North Carolina, Franklin , on Hieracium sp., 1-IX-1963, Pepper leg., 3 apt & 1 al; Raleigh, on Hieracium sp., 4-IV-1964, Stroyan leg., 3 apt & 4 al; Wilmington, on Hieracium sp., 25-IV- 1964, Hille Ris Lambers leg., 3 apt & 5 al; all of them: Hille Ris Lambers det. and Natural History Museum collection.

Apterous viviparous females ( Figure 3 A), complementary data. Spinopleural patch and marginal sclerites (including postsiphuncular) on abdominal segments 2 to 6; straight individual transverse bands on segments 7 and 8 are frequently present but sometimes very light-brown or unpigmented. Siphunculi very swollen, medial part smooth, peduncular portion with transverse wrinkles and very distal part with very few dispersed spinules.

Alate viviparous females ( Figure 3 B), description from 10 specimens. Head brown to dark brown, as dark as thorax. Antennal segments I, II, and proximal part of III paler than the rest of antenna, which is diversely ornamented: segment I widely smooth with small rows, II with scales, III and IV smooth, and V and VI imbricate. Marginal tubercles habitually present on both sides of prothorax, and absent on abdomen. Legs brown, with darker distal half of femora, distal third of tibiae and tarsi. Abdominal segments 2 to 6 with spinopleural transverse bands irregularly edged and sometimes coalescent, but sometimes broken in the middle, plus broad marginal sclerites that are paler than femora and with spinules; abdominal segments 7 and 8 with individual transverse bands also paler than femora and with spinules; intersegmental sclerites integrated in the spinopleural bands but easily visible because of their darker pigmentation. Siphunculi similar to those of apterae. Genital plate as dark as the dorsoabdominal sclerites. Cauda light brown, much paler than siphunculi and as pigmented as anal and genital plates; with setae only on distal half. Quantitative characteristics in table 2.
