| abstract | In this paper, two new species of the family Haemogamasidae are described and figured. All types are deposited in The Yunnan Institute of Epidemic Diseases.
Haemogamasus daliensis sp. nov. (figs. 1-4)
This new species is similar to Haemogamasus liberiensis Hirst, but easily distinguished by the former’s genitoventral plate not bearing three-forked setae and the shape of tectum different. It is also closely allied to H. trifurcisetus Zhou et Jiang, but differs from the latter in: 1) sternal plate with 3 pairs of lyriform organs and St1, St2 St3 plumose; 2). pilus dentilis ribbon-like; 3) tectum rounded-tongue like and midportion with small triangular protrusions; 4) coxa II-IV with unciform process.
Holotype ♀, paratypes 2♀♀ were collected off Eothenomys custos Thomas, from Dali City (25°32’ N, l00°14’ E) Yunnan Province, alt. 3200m in March 1986.
Eulaelaps sinensis sp. nov. (figs. 5-8)
This new species is very similar to Eulaelaps indiscretus Allred but differs from the latter in 1) chela with pilus basalis; 2) posterior portion of peritrematal plate with a lyriform organ; 3) St1 not extending to the posterior margin of sternal plate.
Holotype ♀ was collected off Apodemus sylvaticus orestes Thomas from Jingdong County (24°32’ N, 101°02’ E) Yunnan Province, alt. 2450 m in May 1986. |
