Xyleborus muticus   Blandford, 1894b: 112.

Xyleborus lignographus   Schedl, 1953c: 28. syn. nov.

Xyleborus conditus   Schedl, 1971b: 379. syn. nov.

Type material.

Holotype Xyleborus muticus   ( NHMUK), paratype ( NHMUK). Holotype Xyleborus conditus   ( NHMW). Lectotype Xyleborus lignographus   ( NHMW).

Diagnosis.

3.0-3.1 mm long (mean = 3.08 mm; n = 4); 2.72-2.82 × as long as wide. This species is distinguished by the antennal club distinctly wider than long; protibiae with evenly rounded outer edge; elytral posterolateral costa absent, replaced by a short row of tubercles; declivity lightly shagreened, strial punctures large, deep and distinct; and discal interstrial setae uniseriate.

Similar species.

Xyleborus sunisae   .

Distribution.

China (Fujian, Sichuan), India (Uttar Pradesh), Japan (Honshu, Kyushu), Nepal, South Korea, Vietnam.

Host plants.

This species has been recorded from Quercus   ( Fagaceae  ) and Prunus   ( Rosaceae  ) ( Murayama 1954).

Remarks.

The holotypes of X. muticus   and X. conditus   and the lectotype of X. lignographus   were directly compared. All three specimens were found to be conspecific with minor variations observed in the numbers of setae remaining on the specimens and numbers of granules on the declivital interstriae. Xyleborus conditus   and X. lignographus   are here placed in synonymy with X. muticus   .

Wood and Bright (1992) erroneously reported this species from ' Pinus maximowiczii   '. Murayama (1954) reported the species from Prunus maximowiczii   , Korean cherry, thus the record from Pinus   is incorrect.
