The new species differs from all congeners by the following combination of characters: dorsal shield hypotrichous; dorsal cuticle not hypertrichous; setae st1–st5 present; anal shield with circum-anal setae only; peritremes short; ventral soft cuticle hypertrichous; fixed and movable cheliceral digits edentate; epistome smooth; leg setation not hypotrichous. This new species represents the first Myrmozercon from the Neotropical region. A key to non-Palaearctic species of Myrmozercon is provided.enAcariMesostigmataLaelapidaeMyrmozercon patagonicusantsNeotropicChileArticle
