Descriptions (based on holotype ): Colour : Metallic bronze, compound eyes dark, two basal segments of antennae, last segment of maxillary palpi, claws reddish brown. Body length: 4.96 mm ; body width: 2.56 mm ; body elongate-ovoid, small ( Fig. 6 A); hind wing absent. Head : Clypeus with sparse pubescence, with sparse and small punctures; frons smooth, with sparse and small punctures; coronal suture and frontal suture present; vertex with sparse and dense punctures; compound eyes oblong, dorso-ventral eye length: 0.24 mm , interocular distance: 0.88 mm ; distance from antennal insertion to eye 0.16 mm ; distance from antennal insertion to clypeus 0.09 mm ; mandible with two denticles, outer surface with sparse pubescence, small and sparse punctures; third segment of maxillary palpi shorter than fourth, apex of fourth segment truncate; antennae with basal segments narrow, widening from segments 6 to 11, antennal segment (1–11) lengths (in millimeter): 0.32: 0.16: 0.24: 0.16: 0.16: 0.16: 0.16: 0.16: 0.16: 0.20: 0.32 ( Fig. 6 B). Pronotum : Length: 1.28 mm ; width: 2.40 mm ; central disc with small and sparse punctures, as same as those of head; without callus; punctures lateral to disc and basal part with moderate and dense punctures. Scutellum : Sub-triangular, with sparse punctures. Elytra : suture length: 3.76 mm ; width of elytra: 3.28 mm . Elytron with punctures forming 4 regular double striae, sutural stria present, punctures as strong as those of side of pronotum; interspaces of elytral striae with small and sparse punctures, with horizontal wrinkles; inner edge of epipleura with 2 bristles. Legs : Femora and tibiae with sparse and small punctures, sparse pubescence; tarsomere 1 of male protarsus enlarged; hind tarsi entirely pubescent beneath, relative lengths of hind tarsomeres: 5>1>3>2, tarsomere 5 not ventrally toothed ( Fig. 6 E). Venter : Hypomera without punctures; middle part of intercoxal prosternal process more than half width of apex; prosternum with sparse and small punctures, truncate behind, not emarginate behind; mesoventrite shorter than prosternum between coxae; metaventrite shorter than prosternum, with dense and moderate punctures; mesepisternum, mesepimeron and metepisternum without punctures; abdomen with moderate and dense punctures; pygidium with arcuate apex, without longitudinal depression medially. Median lobe of aedeagus ( Figs. 6 C–D): Basal part narrower than apex, curved in lateral view, flagellum slen- der. Female : Unknown. Remarks. Members of this new species are quite different from any other species of Chrysolina in the morphology of the aedeagus. Type material.
