Diagnosis

See Bates (1891).

Remarks

Unfortunately, we were unable to study any type specimens of this species. The first author of this paper has examined all specimens in IZCAS collection illustrated and identified as M. aequabilis by Chang (1964), concluding that these specimens are M. frontalis and not M. aequabilis . The original description ( Bates 1891) showed that species is bearing strong, sharp frontal carina and 9-segmented antennae with 3 lamellae, which have significant similarities with those of L. sinensis and L. castanea . Therefore, this species is confirmed to belong to Miridiba . Nevertheless, it is necessary to study types of M. aequabilis to confirm the assertion and to include it in a genital morphotype.

Distribution

China (Sichuan).
