Explanation of Names
Possibly a reference to the structure of the aedeagus (trior, trier) -- see below
Numbers
a single species in our area, 10 spp. total(1)
Identification
Aedeagus with three long apical tubes (in Efferia, aedeagus hookshaped; in Eicherax, has 3 short apical tubes). (Parks 1968)
Remarks
Author of genus is LeRoy Parks, then at Oregon State University. He apparently had a short career as an entomologist. The publication notes: "Mr. Parks had nearly completed this paper when his untimely death occurred November 20, 1966. Edited and submitted by Charles H. Martin." A grave memorial indicates his birth year was 1930. (See wikispecies page linked above for details.)
