Comments
This species can be easily recognized by rugose punctation along supraorbital furrows (Fig. 3) and several additional characters: antennae reddish brown with antennomeres 9 and 10 pale and antennomere 11 blackish; each elytron (Fig. 4) with a large yellowish mark extending from the elytral center to a broad yellowish band along the lateral margin, anterad and posterad from the midpoint; profemur and metafemur with approximately half of the apical portion darker, mesofemur with apical portion slightly darker (Figs 1, 2); median lobe of aedeagus with a sclerotized apical portion which is delimited basally by a curved margin (Figs 5–7). In immature specimens, however, the elytral coloration is hardly discernible.
Biological notes
Most specimens were collected by sifting leaf litter along a stream in the forest, sometimes even along the bed of temporary brooks (Fig. 8). Two individuals were observed actively moving on the underside of a wet log lying close to a tiny stream (Fig. 9). In the past ten years, many collecting trips were made to Longwanshan from the middle of April to the beginning of October, covering all altitudes of the area in each trip (300–1500m), and the collections show that the activity period of the adults is during late April through May at the higher altitudes of the area, above 1000m.
