Differences between anophthalmic and aphenopsian beetles: evidences from larvae of Chinese species

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. Main larval morphological characteristics of them provide evidences between aphenopsian and...
