A new species of Ljungh, 1810, , from Jalisco, Mexico, is described and illustrated. In the Neotropical region, is similar to Olmi, 1998, but it is distinguished by the black mesosoma (except prothorax, mesoscutum, and mesoscutellum that are yellow), and the metapostnotum being granulated and not rugose; in the mesosoma is completely black and the metapostnotum is granulated and strongly rugose. In the Nearctic region, the new species is morphologically similar to Krombein, 1962, but it is distinguished by the dull and granulated metapostonotum; in the metapostnotum is shiny and unsculptured. The new species belongs to group 7. The keys to the females of the Nearctic and Neotropical species of this group are modified to include the new taxon.
描述并图示了一种来自墨西哥哈利斯科州的新物种，该物种归属于1810年的Ljungh属。在新热带区，它与1998年的Olmi属相似，但区别在于中体黑色（前胸、中胸盾片和中胸小盾片黄色除外），后胸背板具颗粒状而非皱纹状；而在Olmi属中，中体完全黑色，后胸背板具颗粒状且强烈皱纹状。在新北界，该新物种在形态上与1962年的Krombein属相似，但区别在于后胸背板暗淡且具颗粒状；而在Krombein属中，后胸背板有光泽且无刻纹。该新物种属于第7组。对该组新北界和新热带区物种的雌性检索表进行了修订，以纳入新分类单元。
