Interpretive Summary: Leaf beetles, especially flea beetles, are among the most important insects for U.S. agriculture. Many are serious pests and feed on crops destroying valuable plants costing millions of dollars annually. Others are important biological control agents that can be used to control unwanted and invasive weeds. This work documents genus and species of flea beetles previously unknown to science. It provides descriptions and illustrations of adults, larvae and their life cycle. In addition, a discussion on urban parks as biodiversity hot spots is provided. This study will be useful to biological control workers, taxonomists, ecologists, and anyone interested in plant feeding beetles.

Technical Abstract: Urban ecology is a rapidly expanding discipline depicting cities as dynamic ecosystems that foster new ecological interactions in organisms. Our study highlights how biodiversity research within urban landscapes not only contributes to urban ecology but also spurs the emergence of “urban taxonomy” – the discovery of new species in urban ecosystems. We describe Punctaltica gen. nov., a remarkable new genus of a moss-inhabiting flea beetle found solely in anthropogenic microhabitats within city forest parks in Shenzhen, China. Two species (Punctaltica shenzhen sp. nov. and P. montana sp. nov.) are described and illustrated, and the phylogenetic position of Punctaltica is revealed using a multilocus molecular phylogenetic analysis. We document the complete life cycle and delineate each developmental stage of P. shenzhen through an comprehensive one-year field and laboratory study. Our observations unveil the pronounced influence of moisture levels and seasonal variations on the abundance of P. shenzhen adults. Furthermore, we document rare features of P. shenzhen development among flea beetles, notably theextremely large eggs with lengths reaching up to 61% of adult body length, facultative predatory behavior of the phytophagous larvae, and the reduction of larval development to merely two instars. We discuss the significance of urban ecosystem research, alongside a review of known species descriptions from cities, and discuss the implications of urban taxonomy for city park management planning and future city development.
