Larval morphology plays an important role in taxonomy and phylogeny construction. Larvae of three hypogean Trechini species, representing aphenopsian, semi-aphenopsian and anophthalmic, respectively, are described and illustrated from China. In general, primary setae were identified according to classical theory established by Bousquet and Goulet....
