Puyehuemyia Amorim & Silva & Brown 2018, new genus

Puyehuemyia, new genus Type species, Puyehuemyia chandleri, sp. nov. DIAGNOSIS: Maxillary palpus small, 1-segmented, antennal pedicel widening to apex, first flagellomere slightly wider midway to apex, arista 3-articled. Only R 1 setose among wing veins, R 1 not curved anteriorly toward C at apex, C circumambient. Tibial spurs absent, hind tibia slightly sinuous. Scutum with only one pair of posterior dorsocentral setae, acrostical setae absent. Scutellum with four strong setae evenly spaced at discal margin. Female segments 5���8 telescoped, ending as a sclerotized, possibly parasitoid-type ovipositor, cercus probably absent. COMMENTS: A generic status for this Chilean species seems well justified. Not only is the antenna strikingly different from Opetia, with a 3-articled stylus, but also there are features in the wing venation of Puyehuemyia that differentiates it from the remaining species of the family���particularly, the shape of Sc and R1, and the shape of the basal sector of Rs.
