A new species, Zographetus dzonguensis sp. nov., is described based on three male specimens from Upper Dzongu, North Sikkim District, Sikkim, India. The new species is closely similar to Z. pangi from Guangdong and Z. hainanensis from Hainan, China, from which it is distinguished based on the following combination of external characters: (a) forewing with the white spot at the base of space M3 being sharply pointed at the inner edge and conspicuously more elongated, and (b) on underside of hindwing, all chocolate-brown spots being smaller, in Z. dzonguensis sp. nov. compared with both Z. pangi and Z. hainanensis. In Z. dzonguensis sp. nov., the male genitalia may be distinguished as follows: (c) tegumen and uncus are almost equal in length, (d) the dorsal outline of tegumen is relatively flat, and (e) saccus is distinctly bent upward as angle between vinculum and saccus is more acute than in Z. pangi and Z. hainanensis.
描述了一种新的物种，即来自印度锡金邦上宗古地区的三雄虫，命名为宗古沼腹蛛新种。该新种与来自中国广东的斑沼腹蛛和海南的海南沼腹蛛非常相似，但可通过以下外部特征组合进行区分：（a）前翅 M3 基部的白点在内缘处呈明显尖锐状，且明显更长；（b）在后翅下侧，与斑沼腹蛛和海南沼腹蛛相比，所有巧克力棕色斑点都更小。在宗古沼腹蛛新种中，雄性生殖器可如下区分：（c） 腹板和大颚须几乎等长；（d） 腹板的背轮廓相对平坦；（e） 囊明显向上弯曲，因为连接索和囊之间的角度比斑沼腹蛛和海南沼腹蛛更尖锐。
