The generic name Nagathrips was erected as a sub-genus of Mesothrips for the single species, crenulatus Varatharajan and Singh (2000). Subsequent studies revealed character states that were not included in the original description. These are: prosternal basantra absent; antennal segment III with one slender sense cone, segment IV with three similar sense cones; fore wings parallel-sided with no median constriction. These character states are not found in any species of Mesothrips, a genus of the Tribe Haplothripini (Mound & Minaei 2007), but are typical of members of the Liothrips-lineage (Dang et al. 2014). To confirm such a relationship partial sequence data of the mitochondrial gene (CO1) was obtained and compared with that of Gynaikothrips species.
属名Nagathrips最初是作为Mesothrips的一个亚属建立的，仅包含单一物种crenulatus Varatharajan和Singh（2000年）。随后的研究揭示了一些未包含在原始描述中的特征状态。这些特征状态包括：前胸基腹片缺失；触角第三节有一个细长的感觉锥，第四节有三个相似的感觉锥；前翅两侧平行，无中缢。这些特征状态在Haplothripini族（Mound和Minaei，2007年）的Mesothrips属的任何物种中都未发现，但却是Liothrips谱系成员的典型特征（Dang等人，2014年）。为了证实这种关系，获得了线粒体基因（CO1）的部分序列数据，并与Gynaikothrips物种的数据进行了比较。
