"E. arunachalensis A.N. Rao is most closely related to Eria gloensis and appears indistinguishable from it externally. Both taxa share similar features such as slenderly clavate stems topped by a few leaves, biflorous inflorescences with relatively large floral bracts, pubescent flowers with a prominent subglobose mentum, and a more or less subquadrate lip. However E. gloensis differs in the flowers having a single bicarinate callus on the labellum (vs. two lateral calli, and a median pubescent ridge), and two groups of long, capitate hairs on the midlobe (epichile). E arunchalensis is also allied to E. foetida Aver. from Vietnam. in having tomentose floewrs with globose mentum but differs in the lip which has a shorter midlobe and 3 calli on the disc vs a distinctly longer midlobe a 2 calli
