Orthogonius xanthomerus Redtenbacher, 1867 This species was described from specimens collected by Ritter von Frauenfeld in Hong Kong . It was also collected by both Champion and Bowring prior to 1855. This is likely to be the species Bowring mentions in a 1855 letter to Adam White (Anon 1855). "the other day I got my first specimen of the only beetle in poor Champion's collection, which I did not possess when he left China , an Orthogonius ; I don't know whether it has been described." Gemminger & Harold (1868) , Chaudoir (1871b) , Andrewes (1924) and Bousquet (2003d) also list this species for Hong Kong . Orthogonius sp. A number of specimens were quite different from O. xanthomerus . According to Mingyi Tian (pers. comm.) their genital structures are somewhat intermediate between several species from China and southeast Asia. Material: 1 ex.
