Strumigenys is one of the most diverse ant genera in the world and arguably the most morphologically diverse, exhibiting an exceptional range of mandible shape and function. A new species, Strumigenys ayerstheysp. nov., discovered in the Chocó region of Ecuador is described. With two morphological characters, this species is shown to be a morphologically unique outlier among Strumigenys globally, having predominately smooth and shining cuticle surface sculpturing and long trap-jaw mandibles. Using µCT scans, we produced 3D images of the worker ant and static images to examine and compare mandible articular morphologies with most morphologically similar members of the mandibularis species group. Cuticular, pilosity, and articular mandible morphological differences supports placing the new species in its own new species group.

厄瓜多尔的一种新的Strumigenys属（膜翅目，For科），并对其下颌骨形态进行了描述

Strumigenys是世界上最多样化的蚂蚁属之一，并且可以说是形态最多样化的蚂蚁，其下颌骨的形状和功能范围非常广泛。一个新种，Strumigenys ayerstheysp。介绍了在厄瓜多尔乔科地区发现的11月。具有两个形态学特征，该物种被证明是全球Strumigenys的一个形态学独特的异常，主要具有角质层表面光滑且光亮的雕刻和长下颌下颌骨。使用µCT扫描，我们生成了工蚁的3D图像和静态图像，以检查和比较下颌骨物种组中大多数形态相似的下颌骨形态。角质层，柔毛和下颌骨的形态学差异支持将新物种置于其自己的新物种组中。
