03E56F05FFD7950004374B72605DFD81.taxon	discussion	Remarks: Larvae were collected from the sublittoral zone of a reservoir. They are small with a relatively short basal antennal segment and low antennal ratio and rather shallow lateral notch on the trifid median mental tooth. The mandible resembles somewhat that of Cryptotendipes pseudotener, with two flat inner teeth and a long seta subdentalis that almost reaches the apex of the apical tooth. Of all the described freshwater larvae in this genus, only C. usmaensis, C. emorsus, and C. pseudotender have flat mandibular inner teeth. Cryptotendipes usmaensis and C. emorsus can be separated from our material by the short seta subdentalis reaching no farther than to the second inner tooth, whereas in our material, the seta subdentalis clearly extends to the base of the apical tooth. Cryptotendipes pseudotener can be separated from the larvae of other species, which have a single, broad median mental tooth; our specimens clearly have trifid median teeth. The larva can not be associated with any of the adults described in this paper. We, therefore, treat this larva as C. sp. 1.	en	Yan, Chuncai, Tang, Hongqu, Wang, Xinhua (2005): A review of the genus Cryptotendipes Lenz (Diptera: Chironomidae) from China.

03E56F05FFD19502043748BA668BFBD9.taxon	discussion	Remarks: The larva resembles that of C. usmaensis from Germany. Both have the dome­shaped median tooth without a distinct lateral notch and the mandible with triangular inner teeth hardly extending from the inner margin. Small differences exist in the lengths of the seta subdentalis and the third antennal segment. The seta subdentalis is relatively long, distinctly extending to the base of the apical teeth, and the third antennal segment is about half as long as the fourth segment, whereas in C. usmaensis, the seta subdentalis only extends to the basal inner tooth and the third antennal segment is much longer than the fourth segment. According to Pagast (1931: 221), the ratios between antennal segments are 42: 12: 6: 4.5: 4.5, whereas in our material they are 45: 12: 3: 6: 6. Cryptotendipes sp. 2 can be separated from C. sp. 1 by the triangular inner mandible teeth and the weak pigmentation of the postmentum and the posterior occipital margin. We cannot associate this larva with any adult and, thus, tentatively refer to it as C. sp. 2.	en	Yan, Chuncai, Tang, Hongqu, Wang, Xinhua (2005): A review of the genus Cryptotendipes Lenz (Diptera: Chironomidae) from China.

03E56F05FFD3951C04374EE2600BFD81.taxon	discussion	Remarks: The larva resembles that of C. holsatus described by Lenz (1959), Moller­ Pillot (1984, Netherlands), and Nocentini (1985, Italy). The larva differs from others in the genus by the two­toothed pecten epipharyngis and loosely arranged mental teeth. In the Chinese specimen, SI is a little smaller than SII, SI / SII = 0.6 – 0.7 in length, similar to the Netherlands specimen described by Moller­Pillot (1984), but not as small as in the original description by Lenz (1959). The pupa, male, and female have not been found in China, so we treat this larva as C. sp. 3.	en	Yan, Chuncai, Tang, Hongqu, Wang, Xinhua (2005): A review of the genus Cryptotendipes Lenz (Diptera: Chironomidae) from China.
