A new genus and species of scale insect (Hemiptera: Coccomorpha) is described from a female specimen in mid-Cretaceous Burmese (Myanmar) amber. Fossil female scales are rare and the present species, described as Paleolepidotus macrocolus gen. et sp. n., has such an unusual assortment of morphological features that it could not be assigned to any particular extant or extinct family. The small, ferruginous specimen exhibits a series of long wax pencils that extend around the body, including the head. The antennae and legs are quite long compared to other extant and extinct scale fossils. Of special interest are the protruding eyes, and a conical-triangular rostrum arising from between the forelegs; the claws with bifid apices are also unique. The ovisac contains immature stages.
从一枚产自白垩纪中期缅甸琥珀中的雌性标本描述了一种新的介壳虫属和种（半翅目：蚧亚目）。化石雌性介壳虫十分罕见，当前被描述为巨瘤古蚧属（Paleolepidotus）新种（Paleolepidotus macrocolus gen. et sp. n.）的物种具有如此不寻常的一系列形态特征，以至于无法将其归入任何特定的现存或已灭绝的科。这个小的、铁锈色的标本展示出一系列围绕身体包括头部延伸的长蜡丝。与其他现存和已灭绝的介壳虫化石相比，其触角和腿相当长。特别有趣的是突出的眼睛，以及从前腿之间生出的一个圆锥形三角喙；顶端分叉的爪也很独特。卵囊内含有未成熟阶段的个体。
