It is closely related to the genus Arcofacies Muir in the shape of vertex and frons, but differs in: vertex with length in middle line shorter than width of base about 0.79:1.00 (about 0.53-0.59:1.00 in the latter); frons longer in middle line than widest part about 3.25: 1.00 (about 1.75-2.17:1.00 in the latter); frons with median carina forked at extreme base (not forked in the latter); dorsum of body without median longitudinal stripe from apex of vertex to end of scutellum (in the latter, dorsum of body with a narrow stripe along median longitudinal carina of vertex, pro- and mesonotum, which are often white, bordered with brown or fuscous stripe); forewings rounded at apex (acuate at apex in the latter).
