10 Measurements. Holotype male, total body length 7.1 mm; head length 1.1 mm, maximum head width across compound eyes 1.1 mm, pronotal length 1 mm, maximum pronotal width across base 1.3 mm, elytral length 5 mm, combined maximum elytral width across postmedium 3.1 mm. Paratype male ( Fig. 7C ) 7.5 mm, paratypes females – 8.7–10.1 mm long.

Description. Holotype male ( Fig. 7A, C ). Dorsal and ventral forebody uniformly black. Elytra dark brown, abdomen black. Mouthparts, maxillary palps, antennae and legs dark brown.

Head elliptical, about same wide as long, opaque dorsally and ventrally. Labrum shallowly emarginate medially at anterior margin. Epistoma shallowly emarginate at anterior margin. Frontoepistomal impression moderately deep, distinct. Anterolateral area of frons moderately projected laterodorsad to hold insertion of antenna. Compound eye large, kidney-shaped, strongly emarginate at anterior, subtruncate at posterior margin in lateral view, touching insertion of antenna, moderately prominent in lateral and dorsal aspects. Interfacetal setae not observed. Minimum interocular distance about 0.7× a length of dorsal eye portion. Tempus about half a length of dorsal eye portion, constricted posteriad, posterior temporal angle rounded, head base truncate. Head dorsum densely punctate with flat punctures. Intervening spaces generally as wide as punctures, subopaque. Head dorsal setation inconspicuous, whitish to silvery, short, appressed, in part concealing dorsal surface of head, directed generally anteriad. Epistoma and labrum with much longer but sparser suberect setae. Antenna long, filiform, extending slightly beyond metacoxa when directed posteriad. Basal antennomere slightly thickened, about 1.5–1.6× as long as antennomere two. Antennomere two shortened. Antennomere three about 2.2× as long as antennomere two, as long as antennomere four. Antennomeres 9–10 slightly widened distally. Terminal antennomere slightly arched, apically bluntly pointed, 0.7 mm long, about 2.2× as long as penultimate antennomere and somewhat shorter than combined length of two preceding antennomeres. Terminal maxillary palpomere strongly securiform. Cranial ‘neck’ not exposed from beneath anterior margin of pronotum, subopaque dorsally, glossy ventrally. Pronotum trapezoid, slightly transverse, opaque and flattened dorsally, subtruncate at both anterior and posterior margin. Maximum width across base, slightly expanding medially on lateral margins about midlength, slightly constricted anteriad. Anterior and posterior margin not beaded or rimed. Antero- and posterolateral angles obtuse angulate in dorsal view. Dorsal pronotal punctures small, flat, moderately dense. Intervening spaces variably narrower, opaque while in part microreticulate to slightly glossy when smooth. Dorsal pronotal setae as those on head, effectively concealing sculpture of pronotal disc. Scutellar shield small, elongated, apically rounded, densely punctured and appressedly setose. Elytron widened postmedium, dorsally moderately convex, slightly glossy. Apical sutural angle round- ed. Elytral sculpture of dense, deep, large to smaller punctures and slightly elevated, in part glossy, variably wide intervening spaces building rugulose pattern. Whole dorsum, including both punctures and elevated rugules, covered with inconspicuous, very

11 sparse, short, curved whitish setae. Setae becoming apparently denser on postbasal area. Setae arranged denser and building vague whitish markings on elytra: a narrow transverse band in basal fourth (slightly producing anteriad along suture) and Tshaped band in apical third with longitudinal part of this marking being double (e.g. a narrow band each side of suture). Epipleuron complete, broad at most of its length except at elytral apex, densely punctured and rather densely white setose. Metathoracic wings fully developed (functional). Ventral pterothorax and abdominal sternites densely white setose by short setae, in part effectively concealing their ventral sculpture. Legs long, slender, femora and tibiae subopaque, with whitish, inconspicuous, moderately dense appressed setae. Femora slender, not clavate or thickened. Tibiae subequally long to corresponding femora, metatibia denticulate/serrate at inner margin in distal half ( Fig. 7B ). Tarsomeres somewhat widened likely pointing on arboreal lifestyle. Basal metatarsomere shorter than combined length of remaining metatarsomeres. Male tergite VII and morphological sternite VII broadly rounded at posterior margin. Aedeagus as in Fig. 8 .

Sexual dimorphism. Female ( Fig. 7D ) much larger and stronger globose than male. Female dorsum uniformly dark brown, venter uniformly black. Mouthparts, maxillary palps, antennae and legs brown to dark brown. Minimum interocular distance about 1.3× a length of dorsal eye portion. Tempus about half a length of dorsal eye portion, posterior temporal angle rounded, head base subtruncate. Antenna moderate, filiform with somewhat thickened antennomeres 9–11, extending slightly beyond mesocoxa when directed posteriad. Basal antennomere shortened and thickened, about 1.3× as long as antennomere two. Antennomere two shortened. Antennomere three about 2.2× as long as antennomere two, slightly longer than antennomere four.

12 Antennomeres 9–10 slightly widened distally. Terminal antennomere slightly asymmetrical, apically bluntly pointed, 0.65 mm long, about 2.1× as long as penultimate antennomere and about as long as combined length of two preceding antennomeres. Pronotum trapezoid, transverse, opaque and flattened dorsally, subtruncate at both anterior and posterior margin. Maximum width across base, slightly expanding medially on lateral margins about midlength, slightly constricted anteriad. Elytron strongly widened postmedium, dorsally strongly convex, slightly glossy. Apical sutural angle slightly produced posteriad, rounded. Elytral sculpture of dense, deep, variably large to small punctures and strongly elevated, in part strongly glossy, variably narrow intervening spaces building strongly rugulose pattern. Whole dorsum, including both punctures and elevated rugules, covered with inconspicuous, very sparse, short, curved whitish setae. Setae becoming apparently denser on elevated intervening spaces on postbasal area. Setae arranged denser and building vague whitish markings on elytra: a narrow transverse band in basal fourth (slightly producing anteriad along suture), two-three short longitudinal bands on apical fourth, a zigzagshaped transverse preapical band. Tibiae subequally long to corresponding femora, without modifications. Female basal metatarsomere much shorter than combined length of remaining metatarsomeres. Female tergite VII and morphological sternite VII broadly rounded at posterior margin.

Interspecific variability. Forebody, antennae and legs are black in one paratype, elytra brown in pale brown in one paratype.

Differential diagnosis. This species is unique among all known congeners primarily due to the rugulose, glossy elytra provided with a narrow transverse postbasal and a complex of longitudinal preapical bands of short, dense setae and densely whitish setose periphery of the scutellar shield.

Ecology. Occurs in primary mid-montane rainforest at 1400–1890 m. Diurnal, observed on low vegetation.

Distribution. Arfak Mountains in Doberai Peninsula of New Guinea.
