Description:
<jats:p>Microphthalminae Hartmann-Schröder, 1971 was proposed in Hesionidae to include <jats:italic>Microphthalmus</jats:italic> and <jats:italic>Hesionides</jats:italic>; however, the affinities of these genera to other members of Hesionidae have been debated, and some authors have concluded they do not belong in Hesionidae. Herein, based on morphological characters, a phylogenetic analysis of the subfamily and some other similar poorly-known genera, with an uncertain position in Hesionidae was performed to clarify their affinities. Our results indicate that Microphthalminae, as currently delimited, is paraphyletic. The inclusion of <jats:italic>Struwela</jats:italic>, <jats:italic>Uncopodarke</jats:italic>, and <jats:italic>Westheideius</jats:italic>, a new genus, as well as the recognition of <jats:italic>Fridericiella</jats:italic> are proposed to meet the requirement of monophyly; and as result of this, the elevation in rank to the family level is herein presented. Furthermore, the type species for <jats:italic>Hesionella</jats:italic> and <jats:italic>Struwela</jats:italic> are redescribed, and a new species in the latter is described. A key to identify microphthalmid genera is also included.</jats:p>
