DIAGNOSIS. — This species is separated from the other species of Adenophallusia by the following characters: metanotum with two median projections rounded in dorsal view; first abdominal tergite with a depression resembling an inverted heart in dorsal view. Male: FWs covering the entire abdomen; stridulatory with c. 56 stridulatory teeth; harp crossed by three diagonal veins; median spine of supra anal plate with base enlarged. Male genitalia: both lobes of LLophi with apex of pointed; EndSc oval in dorsal and ventral views, anterior and posterior margins rounded. Female: FWs covering abdomen but not supra anal plate; posterior tip of ovipositor pointed. Female genitalia: posterior margin of copulatory papilla with a median rounded projection in dorsal view.
