Abstract

Three new aphid taxa (Hemiptera: Sternorrhyncha) are described from Lower Cretaceous amber from Myanmar (Burma). A new family, the Verrucosidae Poinar and Brown, is described for the new genus and species Verrucosa annulata Poinar and Brown, which is characterized by 3-segmented antennae, with the third segment composed of 20 annuli, forewing containing only 3 veins radiating from the main vein (Rs, M and distal C), and the forewing membrane covered with scalelike warts. Another new family, the Burmitaphidae Poinar and Brown, is described for the new genus and species Burmitaphis prolatum Poinar and Brown, and the new genus and species Caulinus burmitis Poinar and Brown. This family is characterized by greatly reduced (stub-like) hind wings, 7- segmented antennae, and a greatly reduced rostrum and frons with a protruding median tubercle. In B. prolata, the forewing has only 3 veins radiating from the main vein and the aedaegus is long and highly sclerotized. In C. bunnitis, the forewing has 4 veins departing from the main vein and an elongate cauda is present. These new taxa, together with previously described aphids from Mesozoic deposits, show a high degree of morphological diversity in Cretaceous aphids.
