Scutellum yellowish to piceous. Antennae and other head appendages yellow to yellowish brown. Legs yellow to yellowish brown proximally and darker distally, especially metalegs.

Pronotum usually with distinct strioles at posterior angles, with short, thin, rather inconspicuous longitudinal wrinkles at middle of posterior margin; pronotal punctation slightly finer than on head; coarse setigerous punctures form a broad row along pronotal margins, absent in posterior middle; disc of pronotum with short, thin, longitudinal median scratch. Pronotal microreticulation rather weakly impressed on disc. Elytron with 2-10 dorsal striae, submarginal stria usually absent, present apically only in some specimens. Using 11-stria pattern: stria 1 completely reduced (only weak strioles can be find in very few specimens); striae 2, 4, 6, 8, 10, and 11 usually present complete or slightly reduced basally, stria 2 can be more distinctly reduced basally; remained striae usually differently developed, often present as weak strioles, especially in apical half or completely reduced. Only one specimen with stronger stria reduction: striae 1-3, 5, 7, 9 completely absent, striae 4, 6, 8 reduced to differently developed puncture lines, striae 10 and 11 present, slightly reduced basally. Elytron with distinct, fine punctation; microreticulation weak. Ventral part with extremely fine, scarce, inconspicuous punctation, invisible on metaventrite and metacoxae and more distinct on abdominal ventrites; prosternum smooth medially; metaventrite and metacoxae with weak microreticulation; on abdominal ventrites microreticulation almost invisible; metacoxal plates with more or less short almost longitudinal strioles, abdominal ventrites 1 and 2 with numerous, long, longitudinal strioles from margin to margin, on abdominal ventrites 3 and 4 strioles situated laterally and turn to middle, almost horizontal, abdominal ventrites 5 and 6 without strioles but with rather distinct punctation that sparser medially and forms a dense lateral area at each side.

: The species distinctly varies in intensity of yellow colouration of dorsal surface, especially elytra. The strongly developed yellow elytral pattern is characteristic for the Sandaun populations. Their representatives always have yellow longitudinal elytral bands though in most specimens not completely developed. There is only one specimen from Bewani without elytral bands. The most reduced yellow elytral pattern is characteristic for the East Sepik populations; their representatives have no yellow longitudinal elytral bands. Specimens of the Madang population are rarely without yellow longitudinal elytral bands though the specimens with intensive yellow colouration are less then in the Sandaun. Indonesian specimens are with yellow longitudinal elytral bands, except for the specimen from Sarmi Regency (Foja Mts).

|

: The species evidently varies in number and degree of development of elytral striae. The maximal number of the striae is ten and is characteristic for the Sandaun populations, although specimens with the 6-stria pattern prevail in the Bewani populations. The representatives of the East Sepik and Madang populations have almost exclusively the 6- stria pattern of the elytron, as well as specimens from the Cyclops Mts. Papuan specimen from Elelim has eight elytral striae. The most interesting is the male from Sarmi (Foja Mts) with strongly reduced elytral pattern described above.
