Abstract:An alien invasive species greenhouse frog (Eleutherodactylus planirostris), which is considered as one of the most successful invasive species of amphibians, was found in Honey Park in downtown of Shenzhen (southern Guangdong province, China) in July, 2017. This is the first record of this foreign species in mainland China. Line transect surveys were further conducted in municipal green-land and green belts around Honey Park from 10 July to 16 July, 2017 in order to preliminarily understand how this species influence the native species. During the survey, E. planirostris was only found in the 3 isolated distribution areas in Honey Park, and showed higher population density than native species. We then randomly collected 21 specimens including 2 kinds of color types, and 10 of them were dissected for anatomic study. It was found that all of the adult individuals were females. Cryptopone sp. and Blattella bisignata were the only detected contents in stomach, and no stomach contents were found in the specimens which were made on the alternate day. The proportion of adult and juvenile was 5/15 according to our first survey and 49/2 in the subsequently survey. We considered that the Shenzhen population of the species was experiencing a strong population expansion according to the findings of large number of female individuals, fast growth rate and strong digest ability of juvenile individuals. Plant and garden soil trade might be the major invasion path. The invasion history of this E. planirostris population in Shenzhen still remains unclear and requires long-term monitoring.
