Bark and Ambrosia Beetles of

SYNONYMY

Taxonomic Comments.   This species is very similar to specimens from eastern North America identified as X. intrusus Blandford, differing in minute differences in the denticles of the elytral declivity. Xyleborus intrusus is found from British Columbia to Gautemala, but is isolated from eastern populations of the 'same species' by a large area in central Canada and the Lake states of the U.S. Bright (2019:298) formally proposed the synonymy but this may be premature. In the meantime I believe that all records and names from eastern North America should be treated as pubescens. Pérez Silva et al. (2021) cited X. pubescens from the Mexican state of Chiapas, further complicating matters. This group of species needs revision.

Maps automatically open at the center of the plotted points and the scale is set to encompass all map points. Maps can be resized (scale bar at upper left) and the center moved (place cursor over map and drag) to see other parts of the distribution of the species. Clicking on a map marker will pull up collection event data and a literature citation if present. If any errors are found, please refer to the "series code" which is a unique identifier for a database record in any communications). Coordinates have not been entered for all collection records. Localities outside the New World are not plotted, even though they are listed in the distribution summary and in the table of records.
