Diagnostic Notes

Adult body length 3.5 to 4 mm, body is dull reddish brown, with golden-brown or yellowish hair covering its elytra. This hair hides a series of longitudinal rows of small pits that are visible only when the hair is rubbed or worn off. This species can be confused with the male of P. fur.

The species differs from many other Ptinus spp. in having the elytral surface completely obscured by the vestiture, which consists mainly of dark golden appressed setae. This species is most similar to Niptus hololeucus and Trigonogenius globulus, which also have the elytral surface com-pletely obscured by the vestiture; adults of P. tectusare distinct, however, in hav-ing the area between the antennal insertions narrow instead of wide.

This species is known outside North America by the name Ptinus tectus Boieldieu. However, under article 72C(e) of the International Code of Zoological Nomenclature, the valid name for the Australian spider beetle is Ptinus ocellus Brown, since P. tectus Boildieu was originally proposed as a replacement name for Ptinus pilosus White (= Dorcatoma pilosus White, an anobiid).
