Furniss det., BEM Trypophloeus nitidus Swaine, 1912: 349 = T. striatulus auct., nec Mannerheim, 1853: 235 syn. n. = T. punctipennis Hopkins, 1915: 37 Examined material. Type material: Holotype: Trypophloeus striatulus (Mannerheim, 1853): circle of golden paper // “ Cryphalus striatulus Mnnhm (=Mannerheim), Kenai J.” farther unreadable in ink handwriting, probably “Russam”, ZIN. Comment. The type of the species has been considered lost, at least not found in Mannerheim collection, Finland (Wood and Bright 1992). However, in 1853 both Alaska and Finland were still parts of Russian Empire and thus deposition of the holotype in main country collection, i.e. in the former capital of the Empire (St. Petersburg) was logical. Cryphalus striatulus is the original valid name proposed by Mannerheim for a new species. It was described and really belongs to genus Cryphalus and not to genus Trypophloeus as many authors thought. It is not a new synonym, but a senior name and Cryphalus ruficollis is a new junior synonym of Cryphalus striatulus.

General distribution. North America, including Canada (Newfoundland, Nova Scotia, Quebec, Yukon), Alaska and mountains of western USA (Colorado, Idaho, Minnesota, Oregon, Utah) (Wood and Bright, 1992). Comment. We were not able to find the reference indicating the introduction of the species to Hungary (cf. Knížek, 2011). Host trees. Alnus crispa, A. rugosa, Salix scouleriana, S. alaxensis. Re-descripion. Body: length 1.6–2.2 mm, 2.7 (2.4–3.0) times as long as wide, black or dark brown, brightly shining. Head: frons convex, with Y-shaped impression from upper level of eyes to antennal insertions; surface finely reticulated from upper level of eyes to vertex, shallowly punctured below; pubescence consisting of inconspicuous sparse hairs. Pronotum: widest at base, distinctly transverse, 0.65–0.75 as long as wide; summit slightly behind middle; asperities in front of summit, rather large and abundant, forming concentric rows in anterior half; anterior margin with four to eight contiguous teeth. Surface of lateral and posterior areas shining, punctures rather close, coarse and deep; covered with short hair-like setae, slightly longer ispiratete area. Elytra: glossy, 1.6–2.0 times as long as wide; punctures on striae and interstriae deeply impressed in anterior two thirds, becoming smaller and shallow near declivity; interstriae with small granules on declivity; surface covered with recumbent hair-like strial and interstrial setae, becoming more scale-like at the declivity, and with rows of erect elongated scales on interstriae throughout elytral length. Diagnosis. Distinguished from other species due to reticulated surface of the upper portion of frons and vertex; from T. alni and T. dejevi by more weak punctures in basal half of pronotum and declivity, by elytral vestiture, and by brightly shining body. T. nitidus differs from the North American species T. populi, T. salicis, and T. thatcheri by strong pucturation of elytra organized in rows. These rows of punctures on elytra extending at least two-thirds from the elytral base to declivity. The scale-like pubescence is only present at the declivity.
