Abstract
Summary We describe two new genera with two new species, Crassicorpus maculatus n. gen., n. sp., and Ordicalcaratus inconditus n. gen., n. sp., based on two specimens from northern Myanmar amber. Crassicorpus maculatus n. gen., n. sp. can be characterized by its pro- and mesotibia with two inner apical spurs and one outer apical spur; metabasitarsus with two long apical spurs and two dorsal spines; and CuPb crossing the harp. Ordicalcaratus inconditus n. gen., n. sp. can be characterized by its metatibia only with inner subapical spurs and outer spines; basitarsus with a pulvillus gradually becoming wider toward apex; and second tarsomere with a small pulvillus.
摘要 我们根据缅甸北部琥珀中的两个标本描述了两个新属和两个新种，即Crassicorpus maculatus n. gen., n. sp.和Ordicalcaratus inconditus n. gen., n. sp.。Crassicorpus maculatus n. gen., n. sp.的特征是：前胫骨和中胫骨有两个内侧尖刺和一个外侧尖刺；后胫骨有两个长尖刺和两个背刺；CuPb穿过竖琴。Ordicalcaratus inconditus n. gen., n. sp. 的特征是其跖骨仅具近端内刺和外刺；基跗蹠具向先端逐渐变宽的脉突；第二跗蹠具小脉突。
