The new species is similar to Tyloperla attenuate, but posterior margin of the new species raised as a ridge, a concavity presented at the middle of the ridge, while in the latter, tergum 8 with center area raised, and sensilla basiconica more than the former; tergum 9 of the new species depressed mesally, margin of the concavity sclerotized distinctly, with thin disky sensilla basiconica, while in the latter, a cluster of sensilla basiconica in the middle of tergum 9 distinctly. The type of the new species is deposited in the Insect Collection of Yangzhou University. |
