Psylla (s.l.) kuwayamai Crawford

Psylla tripunctata Kuwayama 1908, p 174 (primary junior homonym of Psylla tripunctata Fitch, 1851 ). Type locality: Taiwan .

Psylla kuwayamai Crawford 1911, p 432 (replacement name for P. tripunctata Kuwayama nec Fitch); Miyatake 1963, p 356; Klimaszewski 1973, p 213; Miyatake 1981, p 59; Yang 1984, p 68; Matsumoto 2004, p 276.

Adults of this species possess short antennae, short female terminalia and six to eight apical metatibial spurs. These morphological features do not fit the genus Psylla (s.s.) or any other existing genera of Psyllinae . For this reason, I leave this species in Psylla (s.l.) until further research including nymphal morphological study. Adult important morphological characteristics of P. kuwayamai of Japan were illustrated in Miyatake (1981), and appear to be different from those of Taiwan, which is the type locality of this species, in genal cones and male terminalia (cf. Yang 1984). Psylla kuwayamai seems to form a well-organized group with the Neolitsea -feeders, Psylla neolitseae Miyatake, 1981 ( Nepal) and Psylla deflua Yang, 1984 (Taiwan) .

Distribution. Japan (Honshu, Shikoku, Kyushu), Taiwan.

Host plant. Neolitsea sericea (Bl.) Koidz. (= Litsea glauca Sieb. ) ( Lauraceae ) in Japan ( Miyatake 1963); Neolitsea parvigenna (Hay.) Kanehira in Taiwan ( Yang 1984).
