A hard tick larva in Cretaceous Burmese amber is described as Cornupalpatum burmanicum n. g., n. sp. Diagnostic characters include a subcircular body with a marginal groove, 11 festoons, elongate four-segmented palpi with the fourth segment distinct and apical, the absence of an anal groove and eyes, and the presence of claws on palpal segment 3. The last character is unique for all members of the Ixodida, both fossil and extant. Aside from the palpal claws and marginal groove, features of the tick larva closely resemble those of members of the genus Aponomma Neumann 1899, considered one of the most primitive tick lineages today, whose hosts are primarily reptiles.
一枚来自白垩纪缅甸琥珀的硬蜱幼虫被描述为新属新种缅甸冠状蜱（Cornupalpatum burmanicum）。诊断特征包括：身体近圆形，具边缘沟；有11个肛褶；触须细长，分四节，第四节明显且位于顶端；无肛沟和眼；触须第三节有爪。最后一个特征在所有硬蜱目成员（包括化石种和现生种）中是独一无二的。除了触须爪和边缘沟外，该蜱幼虫的特征与1899年命名的阿波蜱属（Aponomma Neumann）成员非常相似，阿波蜱属被认为是当今最原始的蜱类谱系之一，其宿主主要为爬行动物。
