Material examined. Bhutan: Pedong , 1.i.–31.xii.1900, coll. R. Oberthür— 1 female, 1 male (syntypes) (Paris MNHN) .

Discussion. The male syntype is obviously missing the pair of short acute spines in middle of apical margin of ninth tergite male that are typical for E. r. rugosifrons as already noted by Griffini (1913a) in the original diagnosis. But a more severe re-examination including relaxing and manipulation of the specimen would be necessary to confirm this. The female differs from E. rugosifrons by the apical groove at the end of the seventh abdominal sternite that is narrower and at the end of the sternite ( Fig. 62K View FIGURE 62 ) while in E. rugosifrons it is more distinct and at the end of an apical prolongation of the sternite ( Fig. 61N View FIGURE 61 ). Moreover, it differs from E. rugosifrons by the possession of distinct relicts of wings Griffini (1913a); squamipterous instead of apterous wing condition. It is thus better regarded as full species instead as subspecies of the latter.

Male ninth abdominal tergite in dorsal view triangularly rounded ( Fig. 62H View FIGURE 62 ); apical margin incurved without spines or teeth but may be hidden due to rolled-up margin ( Fig. 62J View FIGURE 62 ). Subgenital plate wider than long with little diverging lateral margins; apical margin concave, with small styli sitting on rounded apical lateral angles ( Fig. 62I View FIGURE 62 ).

Female seventh abdominal sternite with a small transverse groove before apical margin. Subgenital plate elongate semi-ovoid ( Fig. 62K View FIGURE 62 ). Ovipositor long, slightly upcurved, with simple, subacute tip ( Fig. 62L View FIGURE 62 ).

Measurements after Griffini (1913a) (1 male, 1 female).—body w/o wings: male 27.5, female 32.5; pronotum: male 5.7, female 6.8; tegmen: male 1.5, female 1.7; hind femur: male 15.3, female 17.2; ovipositor: female 19 mm.
