Curculionidae of Guam Author Zimmerman, Elwood C. Entomologist Bernice P. Bishop Museum text 1942 1942-06-01 Bernice P. Bishop Museum Honolulu, Hawaii Insects of Guam I 73 146 book chapter http://doi.org/10.5281/zenodo.5159964 d0309e8b-3179-4162-946c-08cef1c82013 5159964 Genus MACRANCYLUS LeConte Macrancylus LeConte , Am. Phil. Soc., Proc. 14 : 338 , 1876 . Haloxenus Perkins , 2 : 148 , 1900 . Synonymy by Champion , Ent. Mo. Mag. II, 20 : 123 , 1909 . This genus was described as American by LeConte, but I have shown in my "Synopsis of the Genera of Hawaiian Cossoninae " [B. P. Bishop Mus., 0cc. Papers 15(25): 285, 1940] that the genus belongs to the Pacific fauna and that the genotype of Haloxenus is a synonym of the genotype of Macrancylus . In other words, the genotype of Macrancylus is a Pacific insect that has been imported into America. The genus has remained monotypic until now, but the discovery of a new species on Guam indicates that there are more species to be found in the Pacific. [Since this was written, I have described a third species from Samoa (B. P. Bishop Mus., 0cc. Papers 16(7): 172-173, 1941)].
