Diversity and Distribution. Miruantennus is a very small, recently described group consisting of three species primarily distributed in the Palearctic and Indo-Malaysian regions. Miruantennus basalis Otto is a precintive species in southern Laos. The first new species is a precintive species in Yunnan province within the southern region of China. The second new species was taken from two localities within Malaysia.

Lateral pronotal ridge entire, slightly sinuate anteriorly; disc convex usually with pair of small circular foveae; base sinuous. Elytral disc with indistinct striae, except near suture; humeral region moderately striate; interstices flattened. First prothoracic tarsi with straight basal sex combs in males; lateral side of mesothoracic and metathoracic tibiae with hairs and transverse rows of spines; tarsi with basally swollen, simple claws. Notosternal suture as long as the hypomeral base; hypomeron simple, without lateral antennal grooves; metathoracic episterna apically wide; metathoracic coxal plate medially 3.0 times wider than laterally; last visible ventrite forming a strongly produced, truncated beak; last abdominal segment exposed, extending beyond elytral apices in males.
