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.
