Diagnosis.

1.8-2.0 mm long (mean = 1.92 mm; n = 5); 2.86-3.17 × as long as wide. This species is distinguished by the declivital interstriae densely covered with short semi-erect scales; elytral disc medially convex, appearing humped; declivity long, gradual; all declivital interstriae uniformly granulate from base to apex; declivital face convex; and posterolateral costa granulate.

Similar species.

Microperus diversicolor , M. minax , M. quercicola .

Distribution.

China (Fujian, Guangdong*, Guangxi, Hong Kong*, Hunan, Jiangxi*, Yunnan*, Zhejiang*), Japan, South Korea, Taiwan, Vietnam.

Host plants.

Polyphagous attacking both gymnosperm and angiosperm trees ( Beaver and Liu 2010).

Remarks.

Xyleborus pubipennis was recently placed in synonymy with Microperus parvus (Lea, 1894) ( Hulcr and Cognato 2010a). However, the type does not resemble M. parvus at all; the declivity is densely setose and clearly the same as that of M. kadoyamaensis . Hulcr and Cognato (2013) list the occurrence of M. parvus in Vietnam based on their synonymy of X. pubipennis . Microperus parvus occurs in Australasia not the Oriental region. The X. denseseriatus holotype was also examined and found to be conspecific with the syntype series of X. kadoyamaensis . Both X. denseseriatus and X. pubipennis are here placed in synonymy with M. kadoyamaensis .
