The new species Fictor platypapillata was isolated from dung beetle Oniticellus cinctus (Scarabaeidae), collected from the district Balrampur, Uttar Pradesh, India. Fictor platypapillata sp. n. is described based on morphology, morphometric and molecular characterization, supplemented with scanning electron microscopy observations. The new species is characterized by two female morphs based on stomatal dimorphism: α morph with left subventral wall having 14 denticles, six low conical and eight elongated finger-like, slender denticles separated by a deep groove; inner wall of gymnostom with linearly arranged warts; β morph with inner wall of gymnostom lacking warts; dorsal and right subventral stegostomal walls having large, slender teeth with hook-shaped apical end. Genital sensilla eight pairs with v5 pair flattened, button-shaped, located ventrally. The phylogenetic analyses revealed significant congruence, especially in the position of the subordinate taxa of genus Fictor that shows polyphyly by both Bayesian inference and minimum evolution methods. The taxonomy of the genus is updated with a valid species list along with their geographical mapping.
新物种 Fictor platypapillata 是从印度北方邦巴尔兰普尔地区收集的蜣螂 Oniticellus cinctus（金龟科）的粪便中分离出来的。基于形态学、形态计量学和分子特征，结合扫描电子显微镜观察，对新物种进行了描述。该新种的特征是根据气孔二态性分为两种雌性形态：α 形态的左亚腹壁有 14 个齿，6 个低圆锥形和 8 个细长指状，细长的齿由深沟隔开；无孔壁的内表面有线性排列的疣；β 形态的无孔壁缺乏疣；背和右亚腹侧肛侧板有大的、细长的牙齿，顶端呈钩状。性感觉器 8 对，v5 对扁平，呈纽扣状，位于腹侧。系统发育分析显示出显著的一致性，特别是在 Fictor 属的亚分类群的位置上，这表明无论是贝叶斯推断还是最小进化方法都显示出多系性。对该属的分类进行了更新，列出了有效物种及其地理分布。
