Abstract: | The Chinese Cacopsylla species associated with Spiraea are revised. Three new species (Cacopsylla falcata sp. nov., C. nocturna sp. nov. and C. qilianensis sp. nov.) are described, and two [C. hyalinonemae Li and Yang, 1989 and C. spiraeicola (Li, 2011) comb. nov.] are redescribed. A new combination is also proposed for Cacopsylla tetrotaenialis (Li and Yang, 1989) comb. nov. Among the five species, C. falcata and C. qilianensis are affirmed to develop on Spiraea, as fifth instar immatures were found. The host plants of the other species remain uncertain. Based on morphological grounds, it is suggested that C. falcata and C. nocturna are closely related, but that the five species associated with Spiraea do not constitute a monophyletic group. |
