Diagnosis

Preoccipital furrow present, with small interocellar pit;posterior mesosomal comb present.Male genitalia: harpes taken together bell-shaped in ventral and dorsal view; harpe/gvc index 0.41; ventromedial margins of harpes not touching at distoventral margin of gvc, ventromedial margin of harpe convex in basal half, concave in apical half and converging and touching distomedially; ventral margin of harpe convex, dorsal margin straight with indentation between basal and apical half, lateral margin straight and curved at its middle in basal third, convex and oriented distomedially in apical two thirds.

Etymology

The species name is derived from the Latin word ‘ campanula ’ which means ‘bell’, with reference to the bell-shaped harpes of the male genitalia.

Remarks

Comparison with similar species

Aphanogmus campanula sp. nov. and A. pagoda sp. nov. are very similar in having a small interocellar pit, a posterior mesosomal comb and similar stigmal vein to pterostigma marginal length ratios. However, in A. campanula the scape is longer than F1 and F2 combined (scape as long as F1 and F2 combined in A. pagoda ), and the harpe/gvc index is higher (0.41 in A. campanula , 0.27 in A. pagoda ), In addition, the two species differ in the shapes of the ventral, dorsal and lateral margins of the harpes.

Condition of type material

In the holotype, the right F6 to F9, and the left mesotarsus are missing. The left middle leg (except coxa) and the left fore and hind wing are detached. The metasoma is slightly deformed and the posterior third of the metasoma is missing, thus the body length measurement is not precise.
