Proposal of homologies in male flagellar body and setae of <i>Surazomus</i> spp.

Different colors show homologous portions. (A-B) Adult male of S. kitu: (A) dorsal view, (B) lateral view. (C-E) S. sturmi: (C) juvenile, dorsal view, (D) adult male, dorsal view, (E) adult male, lateral view. (F-G) Adult male of S. saturninoae sp. nov.: (F) dorsal view, (G) lateral view. Redrawing from: A-B: Villarreal et al. ([13]: figs 4A and 4C); C: Kraus ([22]: fig 9); D: Armas ([3]: fig 18A); E: Kraus ([22]: fig 8), with seta modifications to match the photograph given by Sturm ([7]: fig 22A). Yellow shows a small portion that includes the stalk and extends dorsally to the base of Dm1. Blue shows a median region that extends from the base of Dm1 to the base of Vm5 and includes the tip of the flagellum. Red areas show the lateral lobes, on which the Dl2 (also marked in red) are attached. Green areas connect the yellow stalk to the red lobes and are more developed ventrally, extending to the base of Vm5.
