Comparative notes. Lathrobium inflexum lacks conspic- uous external characters separating it from other species of moderate size and with a slender pronotum. It is char- acterized particularly by the male primarly and second- ary sexual characters, above all by the shape of the ven- Bonn zoological Bulletin 62 (1): 30-91 tral process of the aedeagus. Based on the similar male and female sexual characters, the species is tentatively at- tributed to the L. varisternale group, although it is not sub- ject to a sexual dimorphism of body size, one of the synapomorphies constituting this group. Distribution and natural history. The species was found in several geographically close localities in the mountain range to the southeast of Longnan, southern Gansu (Fig. 111). It was sifted in great numbers from moss, fern roots, and leaf litter in mixed forests and beneath shrubs at an altitude of 2030-2170 m, in one locality together with an undescribed species represented by a single female. Three specimens are teneral. ©ZFMK.
