Triozidae

Megatrioza eugenioides Crawford (1917)

Reported from Syzygium jambos in HK by Lee & Winney (1981), as a tentative determination, but with no known voucher material.

Megatrioza vitiensis (Kirkaldy, 1907)

No HK vouchers in BMNH but this species was reported from HK by Hodkinson (1986). However, it is likely that Hodkinson’s report refers to the species below, which belongs to the same group but differs from vitiensis .

Megatrioza undetermined sp. 1

Single sample in BMNH, from Syzygium sp. Hill et al. (1982) also refer to this species in HK, as Megatrioza sp. near vitiensis . It is possible that this is also Megatrioza ? eugenioides Crawford (1917) , listed on Syzygium jambos by Lee & Winney (1981), see above, but we retain that as a separate species entry pending further collecting from Syzygium / Eugenia species.

Pauropsylla depressa Crawford (1912)

No HK vouchers in BMNH but this species was reported from HK by Hodkinson (1986).

Pauropsylla udei Rübsaamen (1899)

Three samples in BMNH, from Ficus variegata chlorocarpa and F. variegata . One sample, from F. variegata at Tai O (Lantau I.), comprises only nymphs from near-spherical galls. Hill et al. (1982) described and illustrated the feeding effects of this species on its host. Reported from HK by Lee & Winney (1981).

Trioza camphorae Sasaki (1910)

Single sample in BMNH, from Cinnamomum camphora . Hill et al. (1982) also reported this species from HK, as did Lee & Winney (1981). Sasaki (1910) gave the distribution as the “main island of Japan, Shikoku, Kiusiu, as well as Formosa, South China, etc”.

Trioza erytreae (del Guercio, 1918)

Hill et al. (1982) mentioned this species in discussion of HK Psylloidea, but is unclear whether they were implying its presence in the territory. There are no known HK vouchers of this African pest of Citrus crops, and it is considered that this species is not included in the HK fauna.

Trioza jambolanae Crawford (1917)

Single sample in BMNH, from Syzygium jambos .

Trioza syzygii Li & Yang (1991)

Single specimen present in PPRD, bearing this determination. It was collected in 1975, is dry-mounted and there is no indication of the identity of the determiner. This record is uncertain.

Trioza undetermined sp. 1

Single sample in BMNH, comprising several adults but no nymphs, taken from Ficus microcarpa in Kowloon (coll. Martin).

Trioza undetermined sp. 2

Four vagrant individuals in BMNH, from two separate samplings in the same locality on HK Island .
