Distribution (Fig. 1). China (Yunnan).

Measurements. BL 17.5, HW 4, PL 2.5, PW 4, FWL 6, HFL 10.

Diagnosis. Body size small for most Landrevinae species, brown. Male tegmina with a small but distinct mirror in the stridulatory apparatus. Dorsal field of forewings somewhat square and armed with arc-like margin laterally. Both inner and outer fore tibiae tympanum present. Metanotal gland shiny and smooth for a quarter of apical portion and armed with long hairs for most of base portion. Ramiform branches of epiphallic median lobes armed with claw-like apex.

Remarks. This species was reported recently, located in Yunnan Province, China. Its male genitalia are very similar to those of D. (E.) sonorus in the epiphallic median lobes, having long apical lobules. But, in D. (E.) unguiculatus, the latter lobules are much longer than in D. (E.) sonorus and in all the other species of this subgenus.
