The second Malagasy species of Anacanthiocnemis (Hemiptera: Heteroptera: Reduviidae) with an updated key to the species of the genus

Based on the material collected from Toamasina, east Madagascar, we describe Anacanthiocnemis lihui sp. nov. as the second Malagasy representative of the genus Anacanthiocnemis Reuter, 1882 (Hemiptera: Heteroptera: Reduviidae: Stenopodainae). The new species presents relatively long postocular region of head, widely separated mandibular plates, and different armatures on the profemur, that allow it to be readily distinguished from its congeners. Illustrations and COI barcode of the new species as well as an updated key to the species of Anacanthiocnemis are provided. The known distribution records of Anacanthiocnemis are summarized, showing that the species of the genus occur mainly in tropical rainforests or savannas.
