The
triozid genus Petalolyma
Scott, 1882 is reviewed, and the monotypic genus Torulus Li, 1991, syn. nov., is
considered a junior subjective synonym. Torulus sinicus is transferred to Petalolyma as P. sinica (Li, 1991), comb. nov.,
producing a secondary homonym of P.
sinica Yang & Li, 1984, for which the replacement name Petalolyma lii Liao &
Burckhardt, nomen nov. is proposed here. Adults and fifth instar
immatures of Petatolyma vittata
Liao & Burckhardt, sp. nov. are described and illustrated. The new
species induces marginal fold galls on leaves of Ilex ficoidea
(Aquifoliaceae). The previously unknown male and female of P. lii and P. nigra, respectively, are
described and illustrated, and Petalolyma
castanopsis Li & Yang, 1991 and P. fujianensis Li & Yang, 1999,
syn. nov., are synonymised. Petalolyma
hyalina (Kuwayama, 1910) is considered a nomen dubium as the
original description is not diagnostic and the type material cannot be
found. Hence, Petalolyma
includes currently 13 valid species whose host plant and biogeographic
patterns are briefly discussed. Identification keys for the adults and
fifth instar immatures are provided for the Taiwanese species.
