Stenochiinae is a subfamily of Tenebrionidae with a mainly pantropical distribution, but with a few species distributed at higher latitudes. In general, Stenochiinae has been little studied, and the taxonomic effort been insufficient to understand all its diversity. Recently, a new taxon of Stenochiinae from Central Chile with remarkable morphological characters was collected. Based on phylogenetic analyses of concatenated 28S, 18S, 16S and COI genes and on morphological analyses, a new genus and two species of Stenochiinae are described from Central Chile. Our results suggest that Nestorinus gen. nov. (with the species Nestorinus roitmani sp. nov. and Nestorinus yanettae sp. nov.) has a basal position in Stenochiinae, related to Homocyrtus. The set of morphological characters shared between Stenochiini and Cnodalonini plus their phylogenetic position make it difficult to classify them at tribal level.

综合分类学揭示了智利中部的一个新属，并建议在 Stenochiinae（鞘翅目：Tenebrionidae）中进行系统重排

Stenochiinae是Tenebrionidae的一个亚科，主要分布在泛热带，但少数物种分布在高纬度地区。一般来说，Stenochiinae 的研究很少，分类努力不足以了解它的所有多样性。近期，在智利中部收集到了一个具有显着形态特征的新分类群。基于串联的 28S、18S、16S 和 COI 基因的系统发育分析和形态学分析，描述了智利中部的一个新属和两个种。我们的结果表明 Nestorinus gen。十一月 （与物种 Nestorinus roitmani sp. nov. 和 Nestorinus yanettae sp. nov.）在 Stenochiinae 中具有基础位置，与 Homocyrtus 相关。
