Identification. Our specimens of M. nelsoni are all apterous. They were identified based on the body length between 1.70 and 2.00 mm and the pronotum extended posteriorly over almost the entire dorsum of the thorax. In addition, the body is black, with an orange-red mark on the pronotum (Moreira et al. 2012). The distribution of patches of silvery setae on the abdomen is slightly different from the types of this species, but we believe that this represents intraspecific variation only. The original description of M. nelsoni indicates that silvery patches occur on the sides of abdominal mediotergites I and III – V, and laterotergites III – VI, whereas there are no silvery patches centrally on mediotergites V –VIII. In our specimens, there are silvery patches on the sides of

mediotergites I and III –IV, centrally on mediotergites V – VIII, and on laterotergites III –VII ( Fig. 1A).

Known distribution. Brazil (Moreira et al. 2012).

Distribution in Brazil. Pará ( Cunha et al. 2015), Rio de Janeiro (Moreira et al. 2012), São Paulo (this work).
