Locations where Stenosagola gracilis (triangles) and Stenosagola pseudogracilis (circles) have been collected in New Zealand. Diagnosis. Specimens of S. pseudogracilis are similar in appearance to those of S. gracilis , S. clarkei , S. ramsayi , S. domettensis , and S. eylesi but can be distinguished by the shape of the male genitalia ( Fig. 4a ). Members of this species can be separated from those of S. egmontensis and S. stewartensis by the glossy dorsal surface of the head ( Fig. 1d–f ). Description. Length 1.6–1.8 mm ( Fig. 1d–f ). Head : Winged male head approximately 1.37 times, wingless male 1.37 times, female 1.39 times longer than wide. Winged male eye approximately 0.81 times, wingless male 0.67 times, female 0.35 times as long as temple. Winged male antennomere 3 subquadrate, 4 longer than wide, 5 subquadrate. Wingless male antennomere 3 slightly transverse, 4–5 subquadrate. Female antennomere 3 transverse, 4 subquadrate, 5 transverse. Thorax : Pronotum approximately 1.10 times longer than wide. Winged male elytra approximately 1.66 times, wingless male 1.35, female 1.14 longer than pronotum. Winged male meso- and metaventrites trapezoidal, approximately 1.48 times, wingless male 1.20, female 1.12 longer than pronotum. Aedeagus : Right apical lobe of male genitalia longer than left ( Fig. 4a ). Left paramere broader than right with setae present at tip and middle ( Fig. 4a ). Distribution.
