Genus Cryptorhynchus

Data on Genus Cryptorhynchus (subtribe Cryptorhynchina, tribe Cryptorhynchchini, subfamily Cryptorhynchinae)

Wikipedia states that there are 480 named species of Cophes worldwide. iNaturalist has Observations for only 6 of those species worldwide, with 5 of the 6 occurring in North America - 200 Observations in the U.S. and Canada only. I have found the top one at a single site in Pennsylvania, attracted to the wall at night by outside lights.

C. fuscatus (US, C)
C. lapathi (US, C) - The Poplar-and-Willow Borer
C. tristis (US)
C. helvus (US)
C. obliquus (US)

A larger dataset with one more species is found in the Global Biodiversity Information Facility (GBIF) database - 364 North American Observations & Museum-preserved specimens over 6 species as follows:

C. lapathi
C. fuscatus
C. tristis
C. helvus
C. obliquus
C. minutissimus

The BugGuide platform (which only covers the US and Canada), has a similar number of Observations of the following 4 species in total - all in the US:

C. lapathi
C. fuscatus
C. tristis
C. helvus

The following paper discusses this genus:

"A Review of the Genus Cryptorhynchus Illiger 1807 in the United States and Canada (Curculionidae: Cryptorhynchinae), Robert Anderson, Canadian Museum of Nature, The Coleopterists Bulletin 62, Mar, 2008, pp. 168-180

Abstract

"The genus Cryptorhynchus Illiger 1807 is reviewed for the United States and Canada. Five species [see below] are recognized... Sternochetus woodruffi Sleeper is a new junior synonym of C. helvus. Cryptorhynchus minutissimus LeConte is transferred provisionally to Acalles Schoenherr near Acalles sablensis Blatchley as Acalles minutissimus (LeConte), new combination...A key to the five species is presented along with brief diagnoses, and summaries of natural history and distribution."

C. lapathi
C. fuscatus
C. tristis
C. helvus
C. obliquus
