The South American members of the stiletto fly subfamily Agapophytinae (Diptera: Therevidae) occur in the South American Transition Zone, predominantly in Chile and southwestern Argentina. The four agapophytine genera described from this region are Entesia Oldroyd, 1968; Melanothereva Malloch 1932; Pachyrrhiza Philippi, 1865; and more recently, Sigalopella Irwin & Winterton, 2020. Here we revise Melanothereva and Entesia and describe the new monotypic genus Pachylopella.

The genus Enderlein, 1910 is a remarkable group of mantidflies (Neuroptera: Mantispidae: Mantispinae) distributed from Canada to Argentina, including parts of the Caribbean. This genus comprises nine valid extant species plus an extinct species from the late Oligocene of France. Species exhibit Batesian mimicry with vespid wasps (Vespidae).

The sequential breakup of the supercontinent Pangaea since the Middle Jurassic is one of the crucial factors that has driven the biogeographical patterns of terrestrial biotas. Despite decades of effort searching for concordant patterns between diversification and continental fragmentation among taxonomic groups, increasing evidence has revealed more complex and idiosyncratic scenarios resulting from a mixture of vicariance, dispersal and extinction. Aquatic insects with discreet ecological requirements, low vagility and disjunct distributions represent a valuable model for testing biogeographical hypotheses by reconstructing their distribution patterns and temporal divergences.

In South America, the stiletto fly subfamily Agapophytinae (Diptera: Therevidae) occurs predominantly in the Patagonian region where it is represented by four genera: Pachyrrhiza Philippi, Melanothereva Malloch, Entesia Oldroyd and Sigalopella Irwin Winterton. Here we revise the genus Pachyrrhiza with an additional four new species described and figured.

Stiletto-flies (Diptera: Therevidae) are highly diverse and species-rich in Australia and New Zealand, yet relatively few species have been recorded from neighbouring Papua New Guinea, Indonesia and throughout the remainder of Oceania. Indeed, in New Caledonia only a single species of the widely distributed Australasian genus Macquart (Therevinae) is previously known. Herein we describe two new agapophytine genera (i.

The Chinese stiletto fly fauna is poorly known, with few species previously described and no endemic genera. A new genus and species of charismatic stiletto fly is described from northern China. Although the species was previously known from a poorly preserved specimen, the true form of this apparent bumble bee-mimic was not known until images of a live individual were discovered amongst photographs posted on iNaturalist, an online citizen scientist and biodiversity social network.

Many adult Chrysoperla comanche (Stephens) green lacewings were caught in traps baited with live yeast cultures during tests designed to catch olive fruit flies. All 13 yeast species tested were more attractive than the industry-standard dried torula yeast (Cyberlindnera jadinii; syn. Candida utilis).

The onset of phylogenomics has contributed to the resolution of numerous challenging evolutionary questions while offering new perspectives regarding biodiversity. However, in some instances, analyses of large genomic datasets can also result in conflicting estimates of phylogeny. Here, we present the first phylogenomic scale study of a dipteran parasitoid family, built upon anchored hybrid enrichment and transcriptomic data of 240 loci of 43 ingroup acrocerid taxa.

The last 25 years of phylogenetic investigation into the three orders constituting the superorder Neuropterida-Raphidioptera, Megaloptera, and Neuroptera-have brought about a dramatic revision in our understanding of the evolution of lacewings, snakeflies, dobsonflies, and their diverse relatives. Phylogenetic estimations based on combined analyses of diverse data sources, ranging from adult and larval morphology to full mitochondrial genomic DNA, have begun to converge on similar patterns, many times in accordance with hypotheses put forth by Cyril Withycombe nearly a century ago. These data, in combination with information from the fossil record, have given a revised perspective on the historical evolution and classification of Neuropterida, necessitating an overhaul of their organization and providing focus and insight on fruitful future efforts for neuropterology.

Neuroptera (lacewings) and allied orders Megaloptera (dobsonflies, alderflies) and Raphidioptera (snakeflies) are predatory insects and together make up the clade Neuropterida. The higher-level relationships within Neuropterida have historically been widely disputed with multiple competing hypotheses. Moreover, the evolution of important biological innovations among various Neuropterida families, such as the origin, timing and direction of transitions between aquatic and terrestrial habitats of larvae, remains poorly understood.

Chrysopidae (green lacewings) is the second largest family in Neuroptera, and it includes medium-size lacewings largely recognized by the presence of golden-colored eyes, bright green bodies and delicate wings with dense venation patterns. The subfamily Chrysopinae includes 97% of the species diversity in the family and it is currently divided into four tribes: Ankylopterygini, Belonopterygini, Chrysopini and Leucochrysini. Here we sequenced and annotated the nearly complete mitochondrial genomes of four species of each these tribes: Abachrysa eureka, Italochrysa insignis, Leucochrysa pretiosa, Parankyloteryx sp.
