The genus Taiwanolepta Kimoto, 1989 (type species Taiwanolepta babai Kimoto, 1989) is proposed as a junior synonym of Sikkimia Duvivier, 1891. Sikkimia species from Taiwan form a group characterized by the reduction of their hind wings. Most of them cannot be distinguished using external morphology, except by the structure of last two antennomeres in males. Diagnoses are made by using distribution, aedeagal, and gonocoxal morphology. The group includes one previously described species, Sikkimia babai (Kimoto, 1989), comb. n., and four new species, Sikkimia meihuai sp. n., Sikkimia sufangae sp. n., Sikkimia tsoui sp. n., and Sikkimia yuae sp. n. Speciation models, supporting the high diversity of Sikkimia species in Taiwan, are discussed. Sikkimia metallica Jacoby, 1903 and Sikkimia tamra Maulik, 1936, both from southern India, are transferred to the genus Cerophysa Chevrolat, 1836.
1989年的台湾小瓢虫属（Taiwanolepta Kimoto，模式种为1989年的巴氏台湾小瓢虫Taiwanolepta babai Kimoto）被提议作为1891年的锡金瓢虫属（Sikkimia Duvivier）的次异名。来自台湾的锡金瓢虫属物种形成了一个以后翅退化（缩小）为特征的类群。除了雄性最后两个触角节的结构外，它们中的大多数无法通过外部形态来区分。通过分布、阳茎形态和生殖基节形态进行鉴别。该类群包括一个先前描述的物种，即巴氏锡金瓢虫（Sikkimia babai (Kimoto, 1989)，新组合），以及四个新物种，即美怀锡金瓢虫（Sikkimia meihuai sp. n.）、苏芳锡金瓢虫（Sikkimia sufangae sp. n.）、邹氏锡金瓢虫（Sikkimia tsoui sp. n.）和俞氏锡金瓢虫（Sikkimia yuae sp. n.）。讨论了支持台湾锡金瓢虫属物种高度多样性的物种形成模型。1903年的金属锡金瓢虫（Sikkimia metallica Jacoby）和1936年的塔姆拉锡金瓢虫（Sikkimia tamra Maulik），均来自印度南部，被转移到1836年的Cerophysa Chevrolat属。
