All developmental stages of Teloganopsis orbicularis sp. n. from the Far East of Russia are described here. Male imago of new species is characterized by the rounded lobes of the penis and broad posterior wings. The larvae have light medial longitudinal stripe and groups of short setae on the medial longitudinal stripe on tergites IV-IX. The hypopharynx is roundish; the superlinguae are broad, ovate. The maxillae are uniformly broad with a bevel-edged fang-like top, the palpus is lacking. The glossae are rounded, broad, and closely approximate. The eggs are ellipsoidal with one polar roundish cap. The chorion surface is covered with a net of broad, gently sloping spongy ridges and deep round tartareous meshes. The systematic position of the new species is discussed.
