Valvula 3 of some specimens of <i>E. leucopyga</i> and often in <i>E. polaris</i> is rather broad and square-shaped in dorsal view while it is narrower and tends to be more triangular in the other species. The lancet of <i>E. sordidiapex</i> is the most similar to <i>E. leptostigma</i> and may not always be distinguishable. There might be differences in overall shape:</p><p>– dorsal margin of lamnium almost straight, basal annuli somewhat higher than middle annuli ......... ...................................................................................................................................... <i>E. sordidiapex</i></p><p>– dorsal margin of lamnium somewhat bent, middle and basal annuli of similar height ...................... ..................................................................................................................................... <i>E. leptostigma</i>.</p><p>The lancet of <i>E. polaris</i> is also similar, but the overall shape might be slightly different and it is perhaps (usually?) smaller than in <i>E. leptostigma</i>. The males are not clearly distinguishable from those of <i>E. leucopyga</i>, <i>E. parviserrata</i>, <i>E. sulciceps</i>, <i>E. polepso</i> sp. nov., and <i>E. polaris</i>.
