摘要：The feral nests of Lepidotrigona arcifera was dissected and documented. Adult worker bees from these feral nests were collected and various key morphological characters were analyzed and identified based on previous literature. Within the subgenus Lepidotrigona the "ventralis" species group is varied based on the smaller body size from other species in the subgenus. All structural characters of T.arcifera is closely related to the ventralis group and is varied only the semicircular dark brown band bordering the basal concavity of the first segment instead of dark spots. The present study explained the nest architecture and diagnostic key characters for T.arcifera from North East India
