Paratype (NMNH, 1).

New records.

China: Sichuan, E’bian, 1900 m, 2.vi.1960, Huifen Yin, ex Schima superba (NMNH, 1).

Diagnosis.

5.5 mm long (mean = 5.5 mm; n = 3); 2.12-2.2 × as long as wide. This species is distinguished by the dense mesonotal mycangial tuft that extends laterally from the scutellum to striae 3; declivital posterolateral margin carinate to interstriae 5; elytral disc with a profound transverse saddle-like depression; declivital base with very large incurved spine on interstriae 3, interstriae 3 with four additional equally sized and spaced denticles; declivity broadly sulcate to interstriae 5; elytral disc sulcate anteriad to spine on interstriae 3; large body size; body shiny, appearing polished, largely glabrous, minutely punctate; declivital punctures confused; and pronotal asperities very broad, fine, widely spaced.

Distribution.

China (Sichuan, Yunnan), Myanmar.

Host plants.

Recorded from Schima superba ( Theaceae ).

Remarks.

This species is transferred to Anisandrus because of the visible scutellum, pronotal base with a large, dense setal tuft (indicating a mesonotal mycangium), contiguous procoxae; antennal club type 1, taller than wide, and protibiae triangular.
