urn:lsid:zoobank.org:act:A3C86F23-57EA-4BE5-889E-377490B752 CB

Type species: Hasegawanema mamasaense (Hasegawa, Miyata & Syafruddin, 1999) n. comb.

Hosts: Muridae ( Rodentia ).

Host site: Small intestine.

Distribution: Indonesia.

Etymology: The genus is named in honor of Pr. Hideo Hasegawa (Faculty of Medicine, Oita University, Japan), in recognition of his valuable contribution to knowledge on the Oriental Nippostrongylinae.

Definition: Heligmonellidae , Nippostrongylinae. Synlophe with 15–26 ridges in both sexes. Ridges continuous. Careen supported by two small ridges with ventral one generally slightly larger. Ridge 1’distinct from left ridge. Ridges unequal in size, small to minute. Careen and ridges associated with right ridge, largest. Other ridges very small or minute. Left ridge minute or replaced by a gap in front of the left lateral field. Axis (es) of orientation oblique. Characteristic bursal pattern of type 2-2-1. Dorsal ray divided within proximal half. Each spicule ending in one tip. SpL/BL: 6–25%.

Other species: Hasegawanema mallomyos (Hasegawa & Syafruddin, 1994) n. comb., Hasegawanema maxomyos (Hasegawa, Miyata & Syafruddin, 1999) n. comb., Hasegawanema moatense (Hasegawa, Miyata & Syafruddin, 1999) n. comb., Hasegawanema sulawesiense (Hasegawa, Miyata & Syafruddin, 1999) n. comb.
