The tetragnathid spider genus Tylorida Simon, 1894 is reviewed in India. The relationship of Tylorida with Orsinome Thorell, 1890 is discussed and illustrated. The taxonomic significance of male chelicerae of Tylorida spp. is discussed and an identification key based on the features of male chelicerae to separate Indian Tylorida spp. is provided. A new species, Tylorida flava sp. nov. is described and illustrated. Two new transfers and four new synonyms are proposed: Orsinome marmorea Pocock, 1901 and Tylorida culta (O. Pickard-Cambridge, 1869) are transferred to Tylorida and Mesida Kulczyn'ski, 1911 respectively, Tylorida cylindrata (Wang, 1991) and Tylorida sataraensis Kulkarni, 2014 are synonymised with Tylorida marmorea (Pocock, 1901) comb. nov., Tylorida nicobarensis (Tikader, 1977) is synonymised with Tylorida striata (Thorell, 1877) and Leucauge pondae Tikader, 1970 is synonymised with Tylorida ventralis (Thorell, 1877). The biology, natural history and intraspecific variations of T. marmorea comb. nov. are noted. The occurrence of intraspecific variations and colour polymorphism in T. ventralis is discussed and two colour morphs (Silver and Yellow morphs) and three varieties (varieties I, II & III) for the species are recognised. Additionally, the genus Atelidea Simon, 1895 is recorded for the first time from India and provided the description and illustration of Atelidea nona sp. nov.. The current distribution of Atelidea is mapped.
对印度的长脚蛛科泰勒蛛属(Tylorida Simon,1894)进行了综述。讨论并阐述了泰勒蛛属与奥氏蛛属(Orsinome Thorell,1890)的关系。探讨了泰勒蛛属物种雄性螯肢的分类学意义,并提供了基于雄性螯肢特征来区分印度泰勒蛛属物种的检索表。描述并阐述了一个新物种——黄斑泰勒蛛(Tylorida flava sp. nov.)。提出了两个新的转移和四个新的同物异名:1901年的大理石奥氏蛛(Orsinome marmorea Pocock)和1869年的粗疣泰勒蛛(Tylorida culta (O. Pickard-Cambridge))分别转移到泰勒蛛属和梅氏蛛属(Mesida Kulczyn'ski,1911);1991年的柱状泰勒蛛(Tylorida cylindrata (Wang))和2014年的萨塔拉泰勒蛛(Tylorida sataraensis Kulkarni)与1901年的大理石泰勒蛛(Tylorida marmorea (Pocock) comb. nov.)同义;1977年的尼科巴泰勒蛛(Tylorida nicobarensis (Tikader))与1877年的条纹泰勒蛛(Tylorida striata (Thorell))同义,1970年的庞氏银鳞蛛(Leucauge pondae Tikader)与1877年的腹侧泰勒蛛(Tylorida ventralis (Thorell))同义。记录了大理石泰勒蛛(T. marmorea comb. nov.)的生物学、自然史和种内变异。讨论了腹侧泰勒蛛的种内变异和颜色多态性,并识别出该物种的两种颜色形态(银色和黄色形态)和三个变种(变种I、II和III)。此外,首次记录了印度的1895年的阿特利蛛属(Atelidea Simon),并提供了新物种——诺氏阿特利蛛(Atelidea nona sp. nov.)的描述和插图。绘制了阿特利蛛属的当前分布图。
