178 Euura miltonota group

Valvula 3 (narrow and acute at apex in dorsal view) and lancet (18–24 serrulae, ventrally concave, short spine-like setae, apical sutures slightly or distinctly inclined basally, middle part of basal sutures strongly bent apically) enable separation of the females from those of the other Euura . Males in the group have two types of penis valves. Most of the species ( E. miltonota, E. sagmarius, E. nimbus) have rather characteristic penis valves compared to the other Euura: valvura distinctly longer than ventral margin of paravalva, invagination between valvispina and paravalva broad, ventroapical margin of paravalva broad and round, valvar strut distinctly removed from ventral margin of paravalva along its entire length. Euura halo Prous, Liston & Mutanen sp. nov. penis valve is more similar to that of some other species outside the group (see details under that species).
