Type specimens are valuable resources for investigating and exploring biodiversity on Earth, which has high academic and conservation value. Hemipteran insects are one of the most important and diverse groups in Insecta, and their type specimens have important reference value for many research fields. So far, the data on the type specimens of the Hemiptera in China have not been fully collated.

Through extensive literature review, we have constructed a dataset of type specimens for the new species of hemipteran insects in China published from 1950 to 2017, which includes the data such as collection time, species author, specimen gender, preservation institution and geographical distribution. A total of 6583 type specimen records were collected, covering 3783 new species belonging to 1299 genera and 88 families. This dataset can provide help to the international community for conducting researches on taxonomy, biodiversity patterns, biota evolution, and pest management.
