description: Subfamily ARCOSCALPELLINAE Zevina, 1978Sinoscalpellumgen. nov.
Diagnosis
Capitulum with 14 calcified plates, fully covered, narrow membranous interspace between plates. Carina arched, umbo apical; upper latus rectangular, umbo at submedial of scutal margin, inframedian latus narrow and long, umbo at basi-rostral angle, protruded to below rostrum. Peduncle short, with transverse scales.
Type species
Sinoscalpellum sinensis sp. nov.
Etymology
Sino - from Latin for China, in combination with Scalpellum.
Remarks
The subfamily Arcoscalpellinae is composed of 13 genera. The characters of the new species do not allow it to be accommodated within known genera, so we erected a new genus to accommodate it. The new genus is similar to the genus Planoscalpellum Zevina by the umbo of the upper latus at the sub-medial of scutal margin. The new genus is similar to the genus Verum Zevina by having the following characteristics: apex of carinal latus not extending beyond carinal margin and inframedian latus triangular, umbo basal. But it differs from these by the inframedian latus narrow and long, umbo at basi-rostral angle and protruded to below rostrum.
There is only one species in the genus: Sinoscalpellum sinensis sp. nov.
