“…It is unmodified, sparsely setose in Amoea (Haplogleniini, Figure 8j), Dejuna (Brachynemurini, Figure 9p), Vella (Acanthaclisini, Figure 10f), and Glenurus (Glenurini, Figure 10n). It appears with variously shaped symmetrical sclerites, with more or less developed apodemes in Albardia (Ululodini, Figure 8c,d), Botjederus (Figure 9h) and Bubopsis (Ascalaphini, Figure 9j), to a well‐defined microsetose triangle in Ameropterus (Figure 8f), Ululodes (Figure 8g,h), Ascalorphne (Schuster & Machado, 2022) and Cordulecerus (Ululodini). This triangular microsetose plate is a diagnostic character for the tribe Ululodini (Ascalaphinae), which is recovered as monophyletic because it has the most developed plate within owlflies.…”

Male genitalia morphology in Myrmeleontidae has traditionally been insufficiently studied, although it has received increased attention for its diagnostic value in recent times. A neutral terminology has generally been applied in standard taxonomic practice, yet knowledge of an equivalent and stable terminology across taxa based on comparative morphology has been missing. Herein a detailed comparative morphology study with examples from most tribes within Myrmeleontidae, including owlflies (Ascalaphinae), attempts to relate external and internal genital structures based on a proposed groundplan for Neuroptera and Myrmeleontidae. We contend that a groundplan based on 10 abdominal segments, plus vestigial structures from an 11th segment, coherently depicts structural components across myrmeleontid taxa. A gonarcus, an element of Neuropterida amply referred in Neuroptera, is supported to represent the pair of abdominal appendages of segment X medially fused, with gonocoxite and gonostylus components. In most myrmeleontid taxa, basal (gonocoxites) and distal (gonostyli) components separate, with gonostyli positioned posteriorly with respect to gonocoxites, still united with translucent, lightly sclerotized tissue, forming a more or less conical structure, a proposed synapomorphy for the family. Ninth gonostyli are generally reduced (pulvini) and have migrated close to the base of gonarcus (10th gonocoxites). A pelta, also a potential synapomorphy for Myrmeleontidae, derives from paired setose surfaces of the 10th gonostyli, medially positioned (still evident in Bubopsis). Three structural types of gonarcus are diagnosed for illustrative purposes, as they may represent convergent constructs.
