Abstract: This paper describes the comparative morphology of the three subspecies of Gastrolina depressa Blay: G. depressa depressa Baly, G. depressa pallipes Chen and G. depressa thoracica Baly. Comparison of the morphology, biology and zoogeography, of these subspecies indicate that they should be restored or elevated to species rank: Gastrolina depressa Blay, G. thoracica Baly, and G. Pallipes Chen, stat. Nov. This is based on the following observations: 1) the morphology of labrum, labium, hindwing and claws without distinct differences, however, antenna, mandible, maxillary and spermatheca with distinct differences. From the microscopic morphological comparison, the three subspecies are all with distinct differences. 2) The distribution of G. depressa depressa Baly and G. depressa thoracica Baly is overlapping between 25°-30°N in China, but can be differentiated by altitude in some areas. On the other hand, G. depressa pallipes Chen is mainly distributed in Yunnan Province and does not overlap with the other two species in distribution.
