Comments. This species runs into couplet 9 in Norrbom and PAPP’s (1994) key, where it would go into a third case, wing with microtrichose area entirely covering cells r 2+3 and d, and only part of basal cells is non-microtrichose. The malegenitaliaarepeculiar, withitssurstylusshortandbroadbearingasharp apex and very small thorn.
