An allusion to the small size of the species included in the genus. Gender neutral.</p><p><b>Remarks.</b> The placement of <i>Nanoleon</i> in Myrmeleontidae is undoubted considering the short and clubbed antenna as well as the presence of presectorial crossveins in both wings, but the subfamilial affiliation of the new genus is still unclear. The presence of only one presectorial crossvein in both fore- and hind wings is rarely found in Myrmeleontidae. The result of present phylogenetic analysis suggests its closer relationship with extant antlions. Notably, the new genus possesses the forewing CuP distally fused with A1, which is an important diagnostic character of the subfamily Myrmeleontinae. However, <i>Nanoleon</i> lacks the sensory hair on pro- and mesofemora, and it has relatively long pretarsal claws, apparently being different from the species of Myrmeleontinae.</p> |
