Aspiculuris tianjinensis sp. nov. recovered from the intestine of Clethrionomys rufocanus from Tianjin, China is described and illustrated using light microscopy and scanning electron microscopy. The new species differs from congeners in the shape of the cervical alae, and the number and arrangement of caudal papillae.

Seven species of Cylicocyclus Ihle, 1922 (Nematoda: Strongylidae) were collected from donkeys from Henan Province, China. Five samples of each species were selected for sequencing. Sixteen different internal transcribed spacer (ITS) sequences representing the seven species of Cylicocyclus were obtained. Sequence differences in the first internal transcribed spacer (ITS-1) among species was lower than that of the second internal transcribed spacer (ITS-2). Phylogenetic analyses were conducted using the combined ITS-1 and ITS-2 data sets from the present study and using reference sequences from the GenBank database. The MP and ML trees were similar in topology. The phylogenetic trees were divided into two clades. Clade I included 8 species of Cylicocyclus; within this group, Cylicocyclus leptostomus (Kotlan, 1920) is nested between different samples of Cylicocyclus ashworthi (LeRoux, 1924), suggesting C. ashworthi may represent a species complex. Clade II included Cylicocyclus elongatus (Looss, 1900) and Cylicocyclus ultrajectinus (Ihle, 1920); however, these two species always clustered with the comparative species (Petrovinema poculatum (Looss, 1900) and Poteriostomum imparidentatum Quiel, 1919), suggesting that C. elongatus and C. ultrajectinus represent members of other genera.

Thirty-four donkeys from Henan Province, China, were examined at necropsy for strongyloid nematodes in the caecum (February 2006 to January 2007). Twenty-two species, including 18 Cyathostominae (small strongyles) and 4 Strongylinae (large strongyles), were identified. The five most prevalent Cyathostominae were Cylicocyclus nassatus (73.5%), Coronocyclus labratus (70.6%), Coronocyclus labiatus (67.6%), Cyathostomum tetracanthum (61.8%) and Coronocyclus coronatus (52.9%), accounting for 70.2% of all species identified; C. labratus (124.2 ± 256.4), Cyathostomum tetracanthum (96.4 ± 210.5) and Cylicocyclus nassatus (80.9 ± 117.1) had the greatest mean abundance, whereas Strongylus vulgaris was the most prevalent (88.2%) of the Strongylinae and had the highest mean abundance (34.9 ± 37.8). The numbers of species per donkey ranged from 1 to 15 (with a median of 7.1). Only a small percentage (5.9%) of donkeys were infected by a single species, whereas the other donkeys had infections with multiple species.
