Cecidomyiid genus Bruggmanniella contains four Lauraceae-associated species in Asia and 13 species associated with various plant families in Latin American. In this article, three new species, B. sanlianensis sp. nov., B. turoguei sp. nov. and B. shianguei sp. nov., and one newly recorded species, B. cinnamomi, are reported on Cinnamomum plant species (Lauraceae) from Taiwan. Molecular phylogenetic analysis was conducted for the four Cinnamomum-associated Bruggmanniella, together with B. brevipes Lin, Yang and Tokuda, B. actinodaphnes Tokuda and Yukawa, three Pseudasphondylia and two Daphnephila species. Monophyly of Asian Bruggmanniella and the single origin of Cinnamomum-associated Bruggmanniella were supported based on Neighbor-joining, Maximum-likelihood, and Bayesian inference. The Additionally, Cinnamomum-associated Bruggmanniella species have the closest sistership with B. brevipes that are associated with the plant genus Neolitsea (Lauraceae). These result suggesting B. brevipes, B. actinodaphnes and B. cinnamomi are not members of genus Bruggmanniella that was not consistent with a recent morphology-based phylogenetic study. Among the Cinnamomum-associated linage, a leaf galler B. sanlianensis sp. nov. is a sister to the clade of stem gallers, suggesting that host organ shift from leaf to stem occurred prior to host shift. Besides, paraphyly of the Taiwanese stem galler with respected to Japanese B. cinnamomi implies that the distributional range expansion of B. cinnamomi from Taiwan to Japan.
