A revision of the rugulosus group of Otostigmus subgenus Otostigmus Porat, 1876 (Chilopoda: Scolopendromorpha: Scolopendridae) Author Lewis, John G. E. text Zootaxa 2010 2579 1 29 journal article 10.5281/zenodo.197572 2d6f9a2e-d8f7-4b68-915c-17246687cfe6 1175-5326 197572 Otostigmus armatus Attems, 1953 Otostigmus armatus Attems, 1954: 146 , fig. 15. Laos . Otostigmus armatus : Lewis, 2004 : 27 , figs 1–7. Remarks. Lewis (2004) examined three of Attems’ specimens from Laos and found two to be O . multidens Haase, 1887 and the third probably O . scaber Porat, 1876 . He was unable to examine a further two specimens in the collection of the Naturhistorisches Museum in Vienna as they were too delicate to transport by post. He noted that these specimens might be the ones on which Attems based his description of armatus but that the problem could not then be resolved. On the advice of Sandro Minelli I here designate Lewis’s (2004) O . armatus specimen 1 (an O . multidens ) the lectotype to resolve the problem. The specimen has been removed to a separate tube and so labelled by Verena Stagl. Otostigmus armatus then becomes a junior subjective synonym of O . multidens .
