Type Locality. W Hubei province, Dashennongjia Nat. Res., Muyu, E slope, China .

Diagnosis. This species is separated from other species of Callimoxys by the following combination of characters: pronotum metallic black (♂) or orange to red (♀); all legs metallic black; abdomen dull orange to brown (♀); gena long; clypeus uniformly sparsely punctate and microsculptured; lower eye lobe oblong quadrate; male eye invagination concavity angled dorsally, appearing somewhat flattened; surface of eye invagination finely wrinkled, setae absent; apical 3 antennomeres very long; pronotum length> width, with obvious transverse and longitudinal strigae interspersed with longitudinal arranged punctures on disk, pubescence double with long erect darkly colored setae and extremely short yellow to golden bristlelike, erect setae on lateral aspects, dorsally with 4 widely separated strongly elevated tubercles, with an elevated circular median posterior tubercle, laterally with a single moderately protuberant tubercle, lateroposterior pronotal carina curved and not reaching procoxal cavity; elytra long, covering entire abdomen, surface roughened between punctures; abdominal sternite pubescence of short, decumbent, dense setae; metafemur gradually widened towards apex, entire metafemur with a few scattered, larger, protuberant punctures, and densely covered with smaller contiguous punctures, surface appearing minutely roughened; aedeagus with extremely long ventral lobe; internal sac spicules triangular, uniform in size, forming longitudinal rows.

Remarks. Niisato and Ohbayashi (2005) synonymized C. orientalis with C. retusifer because they were unaware of Holzschuh’ s original description in 1999. Examination of both descriptions suggests that these are the same species. For habitus photo of C. retusifer , see Holzschuh (1999), and for detailed figures, see Ohbayashi et al. (2004).

This species is morphologically unique for Callimoxys . The shape and character of the eyes, pronotum, and elytra are different from any of the North American species. It is also the only species in the group that has long, erect to semi-erect, dark setae located on the pronotum and femora; all other species have only white, grey, or golden setae. Given these differences, the genitalia, however, are typical for Callimoxys . This species is only known from China.
