        | Etymology | Named after Count Nils Gyldenstolpe (1886-1961), a zoologist and ornithologist who was attached to Naturhistoriska Riksmuseet, Stockholm (1914-1961). 
 The genus name was not explained by Lönnberg (1916), but presumably from the Greek isos (equal) plus pachys (thick). Lönnberg states in the diagnosis for the genus "Body cylindrical, a little depressed in front, not tapering towards the posterior end which is abruptly rounded off".
