Psylla omogoensis Miyatake, 1963

Inoue, Hiromitsu, 2010, The generic affiliation of Japanese species of the subfamily Psyllinae (Hemiptera: Psyllidae) with a revised checklist, Journal of Natural History 44 (5 - 6), pp. 333-360 : 337-338

Psylla omogoensis Miyatake

Psylla omogoensis Miyatake 1963, p 335 ; 1969, p 73; Klimaszewski 1973, p 218; Miyatake 1979, p 217; Matsumoto 2004, p 276. Type locality: Japan (Shikoku).

The correct number of apical metatibial spurs of P. morimotoi and P. omogoensis is not “five” as originally described in Miyatake (1963), but “six” based on the holotypes and many determined specimens of both species. Furthermore, the nymphal characteristics of the two species exactly fit the genus Psylla (s.s.) as follows: antenna eight-segmented; anus located terminally; circumanal pore field very large, distinctly extending to the dorsum of abdomen.

Distribution. Japan (Honshu, Shikoku).

Host plant. * Prunus buergeriana Miq. (Rosaceae) (new record).

* Nymphs and newly emerged adults were collected from P. buergeriana at Ooi , Shinano, Nagano Prefecture, Honshu, Japan in June 2001 by S. Usuba ( NIFTS) .

The generic positions of the following six species are not properly settled based only on adults and nymphs are unknown except for Psylla kuwayamai Crawford and Psylla multipunctata Miyatake. Accordingly, I leave these six species in the genus Psylla (s.l. as in Ossiannilsson, 1970) until nymphal morphological studies have been finished.
