Abstract
"In a revision of the subtribe Dolicaonina of the Paederinae, descriptions, illustrations, and a key are presented for the three genera and 78 species in the New World. Acaratopus is described as a new genus with one new species, edenus, from Mexico. Stenopholea is redescribed and nine new species are described; they are bifurca, hadra, luma, sarma, thyma, and trunca from Brazil, papola from Ecuador, and aega and libra from Mexico. Gnathymenus is redescribed and 51 new species are added; they are flatrus, hyllus, kapetus, pipus, stubbus, twapicus, twelfus, and volcanus from Chile, avisoideus, brerus, cleofanus, divisus, garus, limus, mergus, prolixus, siagonus and speccus from Colombia, bobelus, gomphus, plancus, radulus, scoliodontus, setosus, umbus and zarzus from Brazil, angulus, geocus, kestrus, nacodus, spereus and tungus from Ecuador, fiscus and simatus from Venezuela, ascus, catillus, clinus, culebrus, falcatus, pandus, raius, ramosus, sifrus and spirus from Panama, and buganus, hamulus, lirellus, nutatus, patulus, somphus, and virgosus from Mexico. Lithocaon Sharp, Litozoon Bierig, Xanthornobium Scheerpeltz, and Macrognathymenus Coiffait and Saiz are new junior synonyms of Gnathymenus. Gnathymenus macropterus (Bierig) is a new junior synonym of Gnathymenus intermedius (Bierig). Xanthornobium vogelsangi Scheerpeltz, Dolicaon klimai Bernhauer, Litozoon maritimus Bierig, Litozoon intermedius Bierig, Litozoon macropterus Bierig, Litozoon nevermanni Bierig, Litozoon progenitor Bierig, Lithocaon fenyesi Bernhauer, and Lithocaon sparsus Sharp are transferred to Gnathymenus and Dolicaon distans Sharp is transferred to Lobrathium. The 14 Old World genera are briefly discussed. Cladograms are presented for three subtribes of the Paederinae, the 17 genera of the Dolicaonina, and all of the species of Dolicaonina for the New World. The presence of protibial combs is used to help define the Paederinae and to suggest relationship of the Paederinae to the Xantholinini of the Staphylininae. The Dolicaonina and Paederina are sister taxa and together form the sister group of the Cryptobiina. The Dolicaonina are defined by the compressed, pubescent, apically truncate fourth segment of the maxillary palpus, the enlarged, medially fused mesothoracic peritremes, and the medially fused genital sclerites of the female. The cladograms for the species and genera are largely unresolved. The three New World genera are defined by characters of the aedeagus. To avoid a polyphyletic classification, three genera are recognized since each is related to a different Old World genus. The New World species are found from northern Mexico to southern Chile where most have been collected from ground litter and debris at elevations up to 11,600 ft. (3536 m.). More than 60 percent of the species are flightless and have reduced eyes. This study of 78 species is based on 885 specimens from 87 localities"--P. 331.
