Remarks. Liao et al. (2020) provided a detailed comparison between the species and Prop. mexicanus . Although no significant morphological differences were found, further molecular study is needed in order to drive a final conclusion.

The species is considered as lifestyle Type III-e, generalist predators from soil/litter habitats. Ho & Chen (2001) proposed that this species have the potential to become natural enemies of thrips.
