Remarks.

The study of the Andrewes’s type has proved that it belongs to the subtribe Trigonognathina Tschitschérine, 1898, which includes Aristochroa Tschitschérine, 1898, Myas Sturm, 1826 (incl. Trigonognatha Motschulsky, 1858), Steropanus Fairmaire, 1888, and Xenion Tschitschérine, 1902. The presence of the following set of characters: 1/ anterior margin of ligula with four or more setae; 2/ elytra with intervals 1, 3, 5, and 7 wider, more or less distinctly raised and differently colored than the other intervals; 3/ terminal segment of both the maxillary and labial palpi not enlarged, revealed that the only specimen of this taxon belongs to Aristochroa .

The holotype of Aristochroa poecilma was found at Nyima La, a high-mountain passage in the Nyingchi Prefecture, the southeastern part of the Tibet Autonomous Region, China.
