Caenorhabditis inopinata is associated with fresh Ficus septica figs and fig wasps. a A cladogram revealing the evolutionarily relationships of Caenorhabditis, following [46, 47]. The fig-associated C. inopinata is among the closest known relatives of the important model organism, C. elegans. This reduced figure excludes many known species in this group [53]. b An adult C. inopinata female isolated from a fresh F. septica fig. c An adult C. inopinata male isolated from a fresh F. septica fig. d A C. inopinata dauer larva isolated from a fresh F. septica fig. All scale bars in (b–d) are 100 microns. e A female Ceratosolen pollinating wasp. f A Philotrypesis parasitic wasp. g A F. septica plant
