Derivatio nominis. Named from Latin ‘undulatus’ (wavy, uneven) to point on the uneven elytral surface with several impressions. Feminine.

Measurements. Holotype male, total body length 7.1 mm; head length 1.1 mm, maximum head width across compound eyes 1.2 mm, pronotal length 1 mm, pronotal width across anterior edge 0.9 mm, maximum pronotal width across base 1.2 mm, elytral length 5 mm, combined maximum elytral width across postmedium 3.4 mm. Male paratypes 6.9–7.5 mm, female paratypes 8.6–9.6 mm long.

Description. Holotype male. Dorsum and venter uniformly brown to black-brown. Dorsal head with golden to reddish metallic shine, pronotum with reddish to purple and elytra with inconspicuous khaki green metallic shine. Mouthparts, antenna and legs pale brown to brown, terminal antennomeres slightly darker. Head elliptical, hardly transverse, glossy dorsally and ventrally. Labrum deeply emarginate medially at anterior margin. Epistoma strongly and deeply U-shapely emarginate at anterior margin. Frontoepistomal impression deep. Insertion

202 of antenna not concealed. Compound eye large, nearly holoptic, deeply but narrowly emarginate at anterior, subtruncate at posterior margin in lateral view, touching insertion of antenna, strongly prominent in lateral and dorsal aspect. Interfacetal setae not observed. Minimum interocular distance very narrow, about 0.4× as wide as dorsal eye portion. Tempus converging towards head base, less than half eye length, temporal angle rounded, head base concave. Head dorsum densely and coarsely punctate with deep variably shaped punctures. Intervening spaces smooth and glossy, narrower than to as wide as punctures. Head dorsal setation whitish to yellowish, long, suberect, rather sparse, not concealing dorsal surface of head. Antenna long, filiform, touching metacoxa when directed posteriad. Basal antennomere short, slightly thickened, about 1.4× as long as second antennomere. Second antennomere longer than wide. Third antennomere about twice as long as second antennomere, 0.9× as long as fourth antennomere, the longest of 1–10. Antennomeres 5–10 filiform. Penultimate antennomere slightly longer than wide, shortened, widened distally. Terminal antennomere ( Fig. 6B View Figure 6 ) elongate, about 0.9 mm long, asymmetrical, flattened on all edges, apically obliquely pointed, about 4.2× as long as penultimate antennomere and about as long as combined length of 3.5 preceding antennomeres, surface sparsely microtuberculate. Terminal maxillary palpomere small, securiform. Pronotum subtrapezoidal, slightly transverse, glossy and flattened dorsally, subtruncate at anterior, truncate at posterior margin. Maximum width in basal portion, lateral margins gradually widen towards base. Anterior and posterior edge not margined or rimed. Lateral margin not visible in dorsal view. Antero- and posterolateral angles obtuse in dorsal view. Pronotal disc uneven, declivous on lateral sides, shallowly transversely impressed in anterior third ( Fig. 6A View Figure 6 ). Dorsal pronotal punctures large and dense, rather flat. Intervening spaces smooth and glossy, narrower than punctures. Dorsal pronotal setae as those

on head. Scutellar shield small, apically round- ed, densely punctured. Elytron widened postmedium, dorsally moderately convex, glossy. Apical sutural angle narrowly rounded in dorsal view. Elytral lateral margin visible in dorsal view in posthumeral portion of elytron. Elytra with common posthumeral transverse impression on disc; each elytron additionally with four moderately deep lateral impressions, each becoming shallower towards median portion of elytral disc where they disappear; posthumeral impression is smallest and shallowest. Elytral punctures moderately dense, moderately deep. Intervening spaces smooth and glossy, about as wide as to 1.5–2× as wide as punctures. Elytral setae whitish, moderately long, moderately dense, suberect, not concealing sculpture of elytra. Lateral margin of elytra appears somewhat sinuous in lateral view because of elytral impressions. Epipleuron complete, broad at most of its length except at elytral apex, glossy, moderately densely punctured. Metathoracic wings fully developed (functional). Legs long, slender, moderately glossy, tibiae and tarsi with moderately dense whitish to yellowish setae. Femur not clavate. Tibia not to hardly widened distally, male meso- and metatibia hardly arched at external and inner edge, on distal inner margin with some acute denticles ( Fig. 6C– D View Figure 6 ). Protarsomeres slightly widened. Male basal metatarsomere shorter than combined length of remaining metatarsomeres. Male tergite VII and sternite VII broadly rounded at posterior margin. Aedeagus as in Fig. 7 View Figure 7 .

Sexual dimorphism. Female ( Fig. 5C View Figure 5 ) comparatively larger, elytra stronger convex dorsally, minimum interocular distance about 0.8× as wide as dorsal eye length, third antennomere about 2.4× as long as second antennomere, about 1.1–1.2× as long as fourth antennomere, terminal antennomere 0.7 mm long, apically rounded, thicker cylindrical, about 2.6× as long as penultimate antennomere, slightly longer than antennomeres 9–10 combined, meso- and metatibia without obvious denticles, metatibia hardly arched at external and inner edge.

Intraspecific variability. Head with strong blue or purple metallic shine in some paratypes. Differential diagnosis. This species falls into Bothrionota Borchmann, 1936 following the only available key to lagriine genera ( Borchmann 1936). However, the Bothrionota species have margined anterior and posterior pronotal margin, the terminal antennomere is not elongated, the elytra are comparatively stronger elongate and the male meso-and metatibiae not denticulate in this genus ( Borchmann 1936; Telnov & Ruzzier 2024). I therefore tentatively arrange the new species to the genus Lagria Fabricius, 1775 sensu stricto, which is known to be variable in external morphology, until a comprehensive revision of Lagriinae genera becomes available. No congeners with multiimpressed elytra are known from the Papuan Region and surrounding areas. Bothrionota ruzzieri Telnov, 2022 from the North Moluccas (Halmahera) has the elytra comparatively stronger elongate with the conspicuous pale setae, the pronotum is longer than wide, the male terminal antennomere significantly shorter than the combined length of three previous antennomeres (about as long as 3.5 previous antennomeres in L. undulata sp. nov.), the eyes comparatively smaller, and the apex of aedeagus rounded (nearly pointed in L. undulata sp. nov.).

Ecology. Occurs at about 1300–1800 m in primary and degraded mid-montane rainforests, collected both at daytime and attracted to light at night.

Distribution. Arfak Mountains, Doberai Peninsula, New Guinea.
