Tragosoma spiculum Casey, 1890 and T. chiricahuae Linsley, 1959 .

Examination of the holotypes of T. spiculum [type locality: “ New Mexico (Las Vegas)”] (NMNH) and T. chiricahuae [type locality: “Chiricahua Mts, Cochise Co., Arizona ”] (CAS) showed that they are conspecific. Tragosoma spiculum , revised status is the senior synonym and it is therefore the valid name for the species currently known as T. chiricahuae , new synonym. Leng (1920: 266) listed T. spiculum as the southwestern North American subspecies of T. depsarium , with T. pilosicorne [type locality: “ California (Mt. Diablo)”] as a synonym. Because the name T. spiculum has been used as valid after 1899, this prevents from using the provision of Article 23.9 of ICZN (1999) to declare T. spiculum a nomen oblitum and T. chiricahuae a nomen protectum. Since T. chiricahuae has not often been cited in the literature, at least not as a species of economic or ecological importance, I consider the impact on the stability of nomenclature minimal.
