Neobohaiornis lamadongensis was named by Shen et al. (2024) [Referrable to Enantiornithes based on the presence of the following diagnostic features: a furcula with a ventral margin wider than dorsal margin; a proportionately elongate hypocleidium of the furcula; minor metacarpal projecting distally farther than major metacarpal; metatarsal IV mediolaterally thinner than both metatarsals II and III with the trochlea reduced to a single condyle; and a J-shaped metatarsal I. Referred to the enantiornithine clade Bohaiornithidae based on the presence of the following diagnostic features: premaxillary and rostral-most dentary teeth being smaller in size than distal teeth; basally robust teeth with tapered and slightly recurved apices; caudolateral projection of the lateral trabecula of the sternum; distal inflation of the lateral sternal trabecula with greater medial expansion; minor metacarpal proportionately longer than most other enantiornithines; pygostyle tapered caudally (distinct distal constriction absent); and robust proximal phalanges of pedal digits I and II. Neobohaiornis lamadongensis is an icterid-sized (~ 55  g) enantiornithine with the following unique combination of features: ceratobranchial bones rostrally expanded; furcular rami straight, defining a 50˚ angle; robust, medially-curved intermediate lateral trabeculae of the sternum; alular digit ending well before the distal margin of the major metacarpal; penultimate phalanx of the major digit proportionately shorter and robust; alular and major digit unguals reduced; forked cranial processes on the pygostyle strongly developed.]. Its type specimen is MHGU-0288, a skeleton (a nearly complete and articulated skeleton preserved in dorsal aspect with traces of feathers surrounding the skeleton), and it is a compression fossil. Its type locality is Lamadong, Jianchang, which is in an Aptian lacustrine sandstone/mudstone in the Jiufotang Formation of China. It is the type species of Neobohaiornis.
