New records.

China: Shanghai, Dongchuan, vii-viii.2017, Lei Gao, ex trap w/ querciverol (MSUC, 4). Japan: Honshu, Saitama, Chichibu, Takikawa Catchm., 35°55'N, 138°49'E, 850-1060 m, 6.viii.2013 (RABC, 1).

Diagnosis.

2.2-2.5 mm long (mean = 2.3 mm; n = 5); 2.3-2.78 × as long as wide. This species is distinguished by the mesonotal mycangial tuft the length of the scutellum; declivital interstriae 1-4 uniseriate denticulate; discal interstriae punctures uniseriate; declivity appearing bisulcate with impressed from striae 1 to interstriae 2, interstriae 3 distinctly raised; declivital punctures small, uniseriate; shiny appearance; and small body size.

Similar species.

Anisandrus dispar , A. paragogus , Xylosandrus germanus .

Distribution.

China (Heilongjiang, Shanghai*), Japan*, South & North Korea, Russia (European (introduced), Far East), Ukraine. Introduced to USA ( Rabaglia et al. 2009; Gomez et al. 2018a).

Host plants.

Polyphagous, recorded from eight families of trees ( Rabaglia et al. 2009).

Remarks.

Kurentzov (1941) and Terekhova and Skrylnik (2012) provide information on the biology and gallery system, which are similar to A. dispar (see above).

Preliminary phylogenies suggest that Anisandrus maiche is sister to Xylosandrus ( Cognato et al. 2020b). Kurenzov (1941) provided the first valid description of Xyleborus maiche rather than Eggers (1942), which has been widely and incorrectly cited in the literature ( Nikulina et al. 2015).
