SummaryWe 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.
