- <p><b><i>Monoclona</i> Mik</b></p><p><i>Staegeria</i> van der Wulp, 1876: xlix (preoccupied by Rondani, 1856).</p><p>Type species: <i>Sciophila halterata</i> Staeger, 1840 [<i>Sciophila rufilatera</i> (Walker)], by monotypy.</p><p><i>Monoclona</i> Mik, 1886: 279 (nom. n. for <i>Staegeria</i> Wulp).</p><p><b>Diagnosis</b></p><p>[Modified from BORKENT & WHEELER (2013).] Two or three ocelli. Metepisternum setose. Wing membrane macrotrichia reflexed towards wing base; sc-r placed before origin of Rs; R 4 present or absent; anterior fork present, posterior fork absent (M 4 missing), M 1+2 shorter than medial fork.</p><p><b>Remarks</b></p><p>Of 19 species of <i>Monoclona</i> described worldwide (BORKENT & WHEELER 2013; AMARAL et al. 2022), only one is known so far from the Oriental region— <i>Monoclona laosilvatica</i> Ševčík, from Laos. The remaining species are from the Palearctic (six), Nearctic (four), and Neotropical (eight) regions. The species from Singapore, described here based on females, clearly diverges from <i>M. laosilvatica</i>, as discussed below. There are no worldwide revisions of the genus or a phylogeny for the species of <i>Monoclona</i>.</p>
