N1 - Funding Information:
R. Bukontaite, S. Holmgren, P. Perkins, andR. Sites are greatly thanked for their excellent companionship in the field during the 2014 Madagascar Expedition. Emmanuel Toussaint is thanked for his recommendation of the French common name. This project was funded in part by NSF DEB#1402446 (PI K. B. Miller, Co-PI G. Gustafson) and #DEB-1353426 (PI K. B. Miller). G. Gustafson is supported by a NIH IRACDA postdoctoral fellowship (5K12GM063651). J. Bergsten was funded by the Swedish Research Council (grants #2009-3744, #2013-5170), and the Royal Swedish Academy of Sciences.

N2 - The Malagasy endemic whirligig beetle Heterogyrus milloti Legros, 1953 is redescribed. Jumping behavior of H. milloti is reported here for the first time with video recordings provided. Results of a behavioral experiment conducted in the field demonstrate H. milloti jumps in a targeted manner in a downstream direction. The unique habitat of H. milloti is described in detail with both image and video of the habitat included. Morphology of H. milloti is discussed in detail, revealing symplesiomorphies with Spanglerogyrus Folkerts, 1979, characters forming transitional series between Spanglerogyrus and the Gyrininae, and features unique to H. milloti. The potential adaptive significance of these peculiar morphological features in association with the habitat of H. milloti is discussed. Finally, an argument for the necessity of conservation of this species is made, and common names in English, French, Malagasy, and Swedish for H. milloti are proposed to aid conservation efforts.
