PTILOMYMAR Annecke & Doutt, 1961 View in CoL

( Figs 851–883 View FIGURE 851 View FIGURES 852–856 View FIGURES 857–859 View FIGURES 860, 861 View FIGURES 862–864 View FIGURES 865–870 View FIGURES 871–875 View FIGURES 876–883 )

Ptilomymar Annecke & Doutt, 1961c: 24 View in CoL . Type species: Ptilomymar rete Annecke & Doutt, 1961 View in CoL , by original designation.

Diagnosis. Body length 350–665 μm (male 300). Propodeum, petiole and gt 1 with large translucent reticulate lamina ( Figs 859 View FIGURES 857–859 , 860 View FIGURES 860, 861 , 863, 864a View FIGURES 862–864 , 875 View FIGURES 871–875 , 877–880 View FIGURES 876–883 ); propodeal seta large and branched with its base anterior to level of spiracle ( Figs 851 View FIGURE 851 , 860 View FIGURES 860, 861 , 872, 873, 875 View FIGURES 871–875 ).

Discussion. Ptilomymar belongs to the Camptoptera group of genera together with Camptoptera , Camptopteroides , Eofoersteria , Macrocamptoptera , and Stephanocampta . Tarsomere 4 in both Eofoersteria and Ptilomymar is about 2× as long as tarsomere 3, indicating in both cases that tarsomere 4 consists of a fusion of 4 and 5. The peculiar translucent structures described above occur elsewhere only in Stephanocampta (not on gt l, however) where they have a different configuration, and a few undescribed Camptoptera from the Afrotropical region.

Nearctic hosts. Unknown. Ptilomymar specimens are known to be associated with water. We hypothesize that the combination of modified propodeal seta and translucent outgrowths on propodeum and gt 1 is used to trap an air bubble that allows an individual to crawl under the water, presumably by walking down vegetation (not swimming with their wings as in Caraphractus —the air bubble would prevent it from doing that: the individual would just bob to the surface if it let go) to find and parasitize its presumed aquatic host.
