Tragosoma repens Casey, 1924

I studied the only specimen (male) of T. repens in Casey’s collection in NMNH. In its original description, Casey (1924: 226) provides the following information “ Utah (southwestern); Length (♂) 24.5 mm; width 8.0 mm.”, but does not designate a holotype or mention how many specimens his description is based on. However, Lingafelter et al. (2014: 4) consider a single measurement (rather than a range) given by Casey, and the fact that the specimen label data agree with the published record, as an implicit indication that there was only one specimen. They therefore regard the specimen under that name in NMNH as the holotype by monotypy ( ICZN 1999, Art. 72.4.1.1 and 73.1.2). My measurements of length and width of the specimen coincide within a fraction of a millimeter with the single set of measurements given by Casey in the original description and support the type status accepted by Lingafelter et al. (2014: 309, Fig. 143, g, h). The specimen is obviously a representative of the depsarium group and its morphological characters fall within the range of the variation observed in T. harrisii . I consider T. repens , new synonym, to be a junior synonym of T. harrisii .
