( Figs 1–4 ) Description – Body elongate, parallel-sided, moderately convex, shiny, brown, dorsal surface with olive tint; vestiture consisting of sparsely set, moderately long, erect, greyish hairs. Body length 9–16.5 mm . Male ( Fig. 1 ). Body length 9–12.5 mm (n = 3). Head elongate, coarsely and densely punctate, genae and medio-longitudinal area of frons impunctate; frontoclypeal suture deep; genae raised, prominent; clypeus with anterior margin straight; labroclypeal membrane concealed; labrum elongate, longer than clypeus; eyes large, hemispherical, interocular distance half of eye diameter. Maxilla with apical palpomere elongate, broadest at middle. Labium with apical palpomere fusiform, apex not emarginate. Mentum broader than long, nearly flat, with two shallow depressions. Antennae long, extending beyond middle of elytra; antennomeres elongate, slightly broadened toward apex, 6 to 10 with inner apical angle rectangular; antennomere length ratios as 21: 5: 15: 19: 18: 18: 18: 18: 20: 22: 41. Prothorax longer than wide, widest in anterior third, constricted before base; pronotum without lateral carina; disc flattened, slightly depressed before base; punctation coarse and moderately dense, interspaces irregular, broadest in central area. Prothoracic hypomeron and prosternum with fine transverse wrinkles and fine punctures. Prosternum in front of coxae nearly twice longer than width of procoxal cavity; intercoxal process with external portion short, subtriangular, very narrow between coxae, not extending behind coxae. Scutellum elongate, linguliform, impunctate, glabrous. Elytra about 3.5 times as long as wide and 4 times as long as pronotum; sides parallel, somewhat abruptly tapering near apex; disc relatively flat in middle, steeply sloping laterally and posteriorly; punctural rows recognizable (especially the first three), but heavily interrupted by irregularly scattered setigerous punctures grouped into clusters of 2 or 3 on intervals; punctation coarse and sparse; interspaces without microreticulation. Mesoventrite densely punctate and pubescent, with a large smooth and impunctate central area; mesoventral process about ¼ times as wide as mesocoxal width; mesepisternum, metepimeron, metaventrite and metepisternum coarsely and densely punctate and pubescent, punctures of metaventrite tend to be finer toward middle, where fine transverse wrinkles present. Hind wings with incomplete first anal cross-vein. Legs rather long and slender; femora subequal in length to tibiae; fore femora slightly clavate; tibiae subequal in width; femora and tibiae without modifications; tarsi slightly shorter than tibiae. Abdominal ventrites finely and sparsely punctate, punctation becoming denser toward lateral portion; last ventrite rounded posteriorly. Abdominal process as wide as diameter of metacoxae. Aedeagus with basale much longer than apicale; apicale triangular proximally, then narrow and parallel-sided in ventral view ( Fig. 2 ), in lateral view with a dentiform angulation mesally ( Fig. 3 ). Female ( Fig. 4 ). Body length 13.5–16.5 mm (n = 4). Body broader, more robust; antenna shorter and less serrate, extending to middle of elytra; antennomeres much narrower; antennomere length ratios as 16: 4: 16: 15: 15: 15: 15: 15: 13: 12: 27; interocular distance nearly twice as eye diameter; legs shorter.

All paratypes are tagged with the following label: PARATYPUS m or f Arthromacra chifengi MERKL , 2004 [printed on yellow paper]. Remarks – This species can be distinguished from other species of Arthromacra by the hairy dorsal surface and the indistinct but traceable puncture rows on the elytra. The differences between this species and other members of Arthromacra would lead many coleopterists to place it in a different genus. However, the distinguishing features of the genera of the Arthromacra group are vague, and this species shares all the fundamental features with other Arthromacra species , so it seems unnecessary to propose yet another monotypic genus in the unrevised complex of Asian Lagriini . Etymology – This species is dedicated to CHI-FENG LEE at the National Taiwan University, the noted specialist of Psephenidae who collected the holotype and two paratypes . * Acknowledgements – I thank all colleagues mentioned in the list of the depositories in the introduction for sending me valuable types and non-type specimens .
