象鼻兰杜丽亚sp.分布于中国云南北方。根据交配囊基部膨大、鞭毛具瘤、无镖囊和粘液腺等特征，将该新种归为LandouriaGodwin-Austen，1918属。omnastoman。sp.的特征是壳的水平孔，这是该属中唯一的。这一特征类似于另外两个骆驼科/缓蹄龙科分类群，中国属的种PseudaspasitaMöllendorff，1902和日本属的种CoelorusPilsbry，1900。这是该属在中国的第一个被证实的记录，也是Landouria的最东记录。本文为进一步研究水平孔的重复演化提供了分类学基础。
Landouria omphalostoman. sp. is described from northern Yunnan, China. The new species is placed in the genusLandouriaGodwin-Austen, 1918 based on the presence of tuberculated flagellum and swollen basal part in the bursa copulatrix, and on the absence of dart sacs and mucous glands.L. omphalostoman. sp. is characterized by a horizontal aperture of the shell which is unique in the genus. This feature resembles those of only two other camaenid/bradybaenid taxa, species of the Chinese genusPseudaspasitaMöllendorff, 1902 and species of the Japanese genusCoelorusPilsbry, 1900. This is the first verified record of the genus in China and the easternmost record ofLandouria. This paper provides the taxonomic ground work for further studies of the repeated evolution of a horizontal aperture.
