Genus Selenophorus
Pronunciation
Typically pronounced either si-LEE-NO-fer-us or silly-NO-fer-us. First case: major accent on bold capitals and minor accent on plain capitals. Second case: only one accent on the plain capitals. In either case, the only long vowel is the second e in Selenophorus. [PWM note]
Synonyms and other taxonomic changes
A much needed key to the Nearctic species of Selenophorus is forthcoming by Messer & Raber. This paper will supplement Bousquet's 2012 catalogue(1) with several new species, new synonyms, new combinations, and biogeographical extensions.
Explanation of Names
Selenophorus Dejean 1829. Greek: "seleno" (= moon) + "phorus" (= bearing) is a reference to the very shiny appearance of some members of this genus. [PWM note]
Numbers
Two subgenera (Celiamorphus, Selenophorus) last reported to include 38 species in the Nearctic and about 190 total species in the Western Hemisphere(1)
Identification
Serial punctures in elytral striae 2, 5, 7 are characteristic of these four sister genera in North America: Selenophorus, Amblygnathus, Athrostictus, Discoderus. The genera are distinguished in identification keys by Noonan (1985) and Ball & Bousquet (2001).
Range
Western Hemisphere: New World (southern Canada to Argentina), mostly Neotropical(1) plus a few Pacific Islands. New range extensions for the Nearctic species of Selenophorus are continuously updated at the post-2012 Caraboidea Registry. (2)
