This latter genus has seven species described from the Neotropical region, nine from the Nearctic and ten from the Palearctic (BECHEV 1999; CHANDLER et al. 2005; KERR 2014; OLIVEIRA & AMORIM 2014). JASCHHOF & KALLWEIT’S (2004) understanding about this group was similar to MATILE’S (1979a), and reinforced the possible relationship between <i>Aphrastomyia</i> and <i>Mohelia</i>. KERR (2014) made a careful revision of the Nearctic species of <i>Megophthalmidia</i> and also mentioned its similarities with <i>Aphrastomyia</i>. A key for these three genera— <i>Aphrastomyia</i>, <i>Mohelia</i>, and <i>Megophthalmidia</i> — was published by OLIVEIRA & AMORIM (2021).</p><p>The species from Singapore described here unquestionably belongs to the clade (<i>Megophthalmidia</i> + (<i>Mohelia</i> + <i>Aphrastomyia</i> )). All species of <i>Aphrastomyia</i> have an obvious sclerotization of the posterior border of the syngonocoxite ventrally, not seen in the Singaporean species. <i>Megophthalmidia</i> has a flat and elongate syngonocoxite and a largely modified tergite 9 (KERR 2014), two features absent in <i>Mohelia zubirsaidi</i> <b>sp. n.</b> The Afrotropical species of <i>Mohelia</i> have simpler terminalia, but with a general shape and details on most sclerites that differ from the species from Singapore, except for the simple, band-like tergite 9 (OLIVEIRA 2015). The problem of the limits between <i>Aphrastomyia</i> and <i>Mohelia</i> was already in need of solution, but this is beyond the scope of this paper. Some features of this Singaporean species, such as the presence of a short proboscis, the shape of some of the wing veins, etc., suggest that its inclusion in <i>Mohelia</i> may be the best solution for the time being.</p><p>In OLIVEIRA & AMORIM’ s (2021) phylogeny, the clade with <i>Aphrastomyia</i>, <i>Mohelia</i>, and <i>Megophthalmidia</i> belongs in the Leiinae, but is too many nodes distant from the base of the subfamily. The presence of <i>Mohelia</i> in Southeast Asia is another case of an Afro-Oriental distribution pattern (e.g., AMORIM & TOZONI 1995; MATILE 1999), as also seen, e.g., in the genus <i>Platyprosthiogyne</i> Enderlein.</p> |
