This new species can be readily distinguished from all the other Chinese species of the genus by the prominently raised odd elytral intervals. There are three other species (

Pouillaude) from the Himalayan region with similar elytral characters, but they are different from the new species by: pronotal lateral margins not crenulated; odd intervals carinate, of about the same width as the even ones; apical lamella hooked or much longer than its basal width. Among these three, the new species is most similar to

Endophallus (Fig. 8) short and straight, extending to dorsum, the inscribed angle between axes of aedeagus and endophallus about 90°; main portion of endophallus on dorsal side of aedeagus when everted; gonopore (gp, gonopore lobe folded in Fig. 8) located at a little before apical lamella, oriented to dorsal side of aedeagus. Basal tubercle (bt) much larger than in other species, very densely and heavily spined; basal band (bb) absent. Five distinct lobes recognized: dorsal lobe (dl) small, nearly rounded, almost touching bt; right basal lobe (rb) divided into two separate lobes; right basal lobe I (rb-1) elongated, bent to dorsal direction of endophallus, placed at right-dorsal surface, decorated with dense and fine scales; right basal lobe II (rb-2) close to rl-1, bent to apical direction of endophallus, apex pointing out to dorsal direction, without scales; right apical lobe (ra) small, on right side of gp, bent to dorsal direction of endophallus, apex curved; left basal lobe (lb) absent; left apical lobe (la) close to dl, on left side of gp, bent to apical direction of endophallus, apex a little bifid.</paragraph>

Among them, the new species has more plesiomorphies than the others, such as: all odd elytral intervals not carinate, apical lamella unhooked. Moreover,

Dubault, Lassalle & Roux was similar to the new species in external and male genitalia characters, although pronotal lateral margins are not crenulate and odd intervals not raised.. Thus, all seven species are assumed to be associated with and forming one species group defined by: (1) short metepisternum, length less than or subequal to its basal width; (2) elytra third interval without setigerous pore; (3) pronotal lateral margins distinctly sinuate before posterior angles, large, deep basal fovea; (4) relatively small body size, generally less than 24 mm.
