Aenigmatistes Shelford, 1908

Aenigmatistes Shelford View in CoL (total of one photo of one mating event examined: Figure 1A View Figure 1 )

Aenigmatistes View in CoL has an accentuated sexual dimorphism with the males conserving a relatively common body shape and structures while the females are apterous and highly modified, with a limuloid shape adapted to live in nests of social insects ( Brown 1993). Figure 1A View Figure 1 illustrates the first record of specimens of this genus copulating. Despite the dimorphism with the male being much larger than the female, they conserve the general mating position. Aenigmatias View in CoL , a closely related genus, has a similar dimorphism with the male additionally presenting modified foretarsi which were inferred to be used in transporting the female during copulation ( Dupont and Pape 2007).
