A redescription of Schulzinema miroljbovi Krastin, 1937 (Nematoda: Strongyloidea)

Abstract

A redescription of Schulzinema miroljubovi, a parasite of the Asian cervid, Cervus nippon hortulorum, is presented, including the first description of the female and a new interpretation of the hook-like internal corona radiata that relates this nematode to Agriostomum Railliet, 1902, a strongyloid nematode parasite of Asian and African bovids. Schulzinema and Agriostomum share the characteristics of medium-sized body thickest at the level of the oesophageal bulb, a thick-walled buccal capsule, hook-like elements of an internal corona radiata, a thin sclerotized buccal collar surrounding the buccal capsule, a large oesophageal funnel with three teeth, a short dorsal gutter, a large club-shaped oesophagus with a thick cuticular lining, cephalic papillae that are not completely fused, spicules with striated alae and copulatory bursa and J-shaped ovejectors of the Chabertia type. Schulzinema differs from Agriostomum in its anteriorly directed oral opening, a symmetrical buccal capsule, the presence of an external corona radiata, and the presence of dorsal and ventral cervical cuticular inflations. Schulzinema provides a link between the Chabertiinae and Agriostomum which until recently was believed to belong to the Ancylostomatoidea. ac]19830624
