Seldon (1, NZAC).   
 Diagnosis. This is the only known member of the genus; therefore, it may be recognized by the characters given in the generic diagnosis above.   
 Description. Length 1.50–1.53 mm. Color of body (Fig. 26) dark brown, legs, mouthparts, and antennal club lighter; each elytron with broad light maculation extending from basal 1/4 to apical 1/3. Dorsal setae uniformly golden, vestiture converging to pronotal midline, undulating near base of the elytra, pronotum and elytra with long, decumbent setae, appearing somewhat longer on pronotal disc and apex of elytra, with scattered suberect setae. Ventral surfaces with recumbent setae, shorter in length compared with those on dorsum; densely punctate; prosternal process with sparse decumbent setae; punctation of metaventrite less coarse than prosternum, smaller in size at the center of disc, larger laterally; abdominal ventrites with punctures less impressed than those on metaventrite and in a matrix of micropunctate microsculpture, ventrite 5 bearing a patch of posteriorly-directed setae with a small impression at middle of sclerite.   
Head punctate with smooth and shiny interspaces. Antennomere 2 globular, as long as wide, antennomeres 3 and 4 about as long as wide, narrower than 2 and slightly shorter than 5; antennomere 11 longer than 10, shorter than 9 and 10 combined. Pronotal length/width ratio ~0.82, widest at apex, wider across anterior angles than across posterior angles; lateral edges divergent, gradually widened anteriorly, anterior angles not projecting, posterior angles projecting posterolaterally and obtuse, posterior margin bisinuate, with narrow scutellar lobe; pronotum with a moderately deep medial fovea; paralateral plicae absent; pronotal punctation similar to that of frons, punctures separated by about two puncture diameters or less, with smooth and shiny interspaces, punctures larger in fovea, larger and contiguous at base. Elytra about 1.99× longer than combined width, about 1.27× wider than pronotum at greatest width, about 3.10× longer than pronotum at greatest length; punctation dense, punctures separated by 1–3 puncture diameters; sutural stria present to basal 1/3; disc lacking impressions.  
 Remarks. Unfortunately, the head and prothorax of the photographed (paratype) specimen were subsequently lost.   
 Etymology. Named for Yandong Chen (Institute of Zoology, Chinese Academy of Sciences, Beijing, China), enthusiastic microcoleopterist and keen beetle collector who collected the holotype specimen of this species.
