Elasmognathus helferi Fieber 1844
Material examined: 1 ɗ, Laos, Vientiane prov., Ban Van Eue, 14.IV.1965, J.L. Gressitt coll., Bishop. Comments: This specimen corresponds to E. helferi, but the costal area is irregularly biseriate or uniseriate, not triseriate as in E. helferi (see Drake & Davis 1960, fig. 55). Such a difference on a single specimen cannot justify the description of a new species. This species is known from India and Philippines.
