Etymology. This species is named for the collector of the holotype, J. S. Dugdale.

Winged male eye approximately 1.45, wingless male 0.82 times longer than temple. Winged male antennomeres 3–8 subquadrate, 9 slightly transverse, 10 transverse. Wingless male antennomeres 3–6 subquadrate, 7–10 transverse. Thorax: Pronotum as long as wide. Winged male elytra approximately 1.85 times, wingless male 1.32 longer than pronotum. Winged male meso- and metaventrites trapezoidal, approximately 1.59 times, wingless male 1.19 times longer than pronotum. Aedeagus: Apical lobe of male genitalia broadly bifid, left lobe longer than right ( Fig. 10d ). Paramere symmetrical, setae present anteriorly ( Fig. 10d ).
