03AAD00156412C6DFD80F9F22D82285F.taxon	diagnosis	Diagnosis Adult Body size moderately small, length about 5.0 – 9.0 mm; body color dark-brown. Cephalic setal warts similar to those of Apatania, with a pair of lateral ocelli. Fore wings transparent, with a patch of dense hairs near the apex of vein Sc; vein R with a row of close, short, black hairs from the apex to the sub-base (Mosely 1942); FI – III and FV presented in both fore and hind wings; discoidal cells in the fore wings are closed but are open in the hind wings. Spurs 1, 2, 4. Abdominal sternum V with a lateral process on each side in male, by which males are easily separated from any other genus of the tribe Apataniini. However, due to the absence of such structures, females of the genus must be identified by a short apical vulvar lobe of sternum VIII and a roof-shaped, slightly sclerotized segment X. The vulvar lobes of sternum VIII in female Apatania Kolenati, 1848 are usually slender, thumb-like or slender, rectangular.	en	Xie, Yue, Wang, Beixin, Sun, Changhai (2017): Associations and a new species of the genus Apatidelia (Trichoptera, Apataniidae) from China.

03AAD00156462C6EFDE0FE5C28D42A65.taxon	diagnosis	Diagnosis Male The new species is very similar to A. acuminata in male genitalia, but differs from the latter in that (1) paired internal branches are finger-like, much shorter than those of A. acuminata; (2) each external branch is sinuate in dorsal view with its apex acute in the new species, but is arc-shaped with the apex obtuse in A. acuminata; (3) each inferior appendage is stout in ventral view in A. morsei sp. nov., but is slender in A. acuminata; (4) FI is sessile in A. morsei, but is petiolate in A. acuminata. The new species can be separated from A. martynovi by the external branches being sinuate with the apex acute in dorsal view, as in A. martynovi it is arc-shaped with the apex bulging. It can easily be separated from A. gansuensis by the distal segments of inferior appendages, which are acute apically, but bifurcate in the latter. It differs from A. egibiel in the overall shape of the phallic apparatus. In addition, the new species can be separated from A. mirabilis by sickle-shaped external branches in lateral view, by short internal branches, and by each distal segment being about twice the length of the basal segment. Female The female of the new species is similar to Apatidelia acuminata, but differs in that (1) the lateral margin of segment IX is depressed at mid-length in lateral view, but is straight in A. acuminata; (2) apicodorsal sclerites of the posterior lobe of IX are close to each other in dorsal view, but widely separated in A. acuminata; (3) lateral lobes of IX in ventral view are somewhat elliptical, but rectangular in A. acuminata.	en	Xie, Yue, Wang, Beixin, Sun, Changhai (2017): Associations and a new species of the genus Apatidelia (Trichoptera, Apataniidae) from China.
